# McRogueFace Tutorial Parts 6-8: Implementation Plan
|
||||
|
||||
**Date**: Monday, July 28, 2025
|
||||
**Target Delivery**: Tuesday, July 29, 2025
|
||||
|
||||
## Executive Summary
|
||||
|
||||
This document outlines the implementation plan for Parts 6-8 of the McRogueFace roguelike tutorial, adapting the libtcod Python tutorial to McRogueFace's architecture. The key discovery is that Python classes can successfully inherit from `mcrfpy.Entity` and store custom attributes, enabling a clean, Pythonic implementation.
|
||||
|
||||
## Key Architectural Insights
|
||||
|
||||
### Entity Inheritance Works!
|
||||
```python
|
||||
class GameEntity(mcrfpy.Entity):
|
||||
def __init__(self, x, y, **kwargs):
|
||||
super().__init__(x=x, y=y, **kwargs)
|
||||
# Custom attributes work perfectly!
|
||||
self.hp = 10
|
||||
self.inventory = []
|
||||
self.any_attribute = "works"
|
||||
```
|
||||
|
||||
This completely changes our approach from wrapper patterns to direct inheritance.
|
||||
|
||||
---
|
||||
|
||||
## Part 6: Doing (and Taking) Some Damage
|
||||
|
||||
### Overview
|
||||
Implement a combat system with HP tracking, damage calculation, and death mechanics using entity inheritance.
|
||||
|
||||
### Core Components
|
||||
|
||||
#### 1. CombatEntity Base Class
|
||||
```python
|
||||
class CombatEntity(mcrfpy.Entity):
|
||||
"""Base class for entities that can fight and take damage"""
|
||||
def __init__(self, x, y, hp=10, defense=0, power=1, **kwargs):
|
||||
super().__init__(x=x, y=y, **kwargs)
|
||||
# Combat stats as direct attributes
|
||||
self.hp = hp
|
||||
self.max_hp = hp
|
||||
self.defense = defense
|
||||
self.power = power
|
||||
self.is_alive = True
|
||||
self.blocks_movement = True
|
||||
|
||||
def calculate_damage(self, attacker):
|
||||
"""Simple damage formula: power - defense"""
|
||||
return max(0, attacker.power - self.defense)
|
||||
|
||||
def take_damage(self, damage, attacker=None):
|
||||
"""Apply damage and handle death"""
|
||||
self.hp = max(0, self.hp - damage)
|
||||
|
||||
if self.hp == 0 and self.is_alive:
|
||||
self.is_alive = False
|
||||
self.on_death(attacker)
|
||||
|
||||
def on_death(self, killer=None):
|
||||
"""Handle death - override in subclasses"""
|
||||
self.sprite_index = self.sprite_index + 180 # Corpse offset
|
||||
self.blocks_movement = False
|
||||
```
|
||||
|
||||
#### 2. Entity Types
|
||||
```python
|
||||
class PlayerEntity(CombatEntity):
|
||||
"""Player: HP=30, Defense=2, Power=5"""
|
||||
def __init__(self, x, y, **kwargs):
|
||||
kwargs['sprite_index'] = 64 # Hero sprite
|
||||
super().__init__(x=x, y=y, hp=30, defense=2, power=5, **kwargs)
|
||||
self.entity_type = "player"
|
||||
|
||||
class OrcEntity(CombatEntity):
|
||||
"""Orc: HP=10, Defense=0, Power=3"""
|
||||
def __init__(self, x, y, **kwargs):
|
||||
kwargs['sprite_index'] = 65 # Orc sprite
|
||||
super().__init__(x=x, y=y, hp=10, defense=0, power=3, **kwargs)
|
||||
self.entity_type = "orc"
|
||||
|
||||
class TrollEntity(CombatEntity):
|
||||
"""Troll: HP=16, Defense=1, Power=4"""
|
||||
def __init__(self, x, y, **kwargs):
|
||||
kwargs['sprite_index'] = 66 # Troll sprite
|
||||
super().__init__(x=x, y=y, hp=16, defense=1, power=4, **kwargs)
|
||||
self.entity_type = "troll"
|
||||
```
|
||||
|
||||
#### 3. Combat Integration
|
||||
- Extend `on_bump()` from Part 5 to include combat
|
||||
- Add attack animations (quick bump toward target)
|
||||
- Console messages initially, UI messages in Part 7
|
||||
- Death changes sprite and removes blocking
|
||||
|
||||
### Key Differences from Original Tutorial
|
||||
- No Fighter component - stats are direct attributes
|
||||
- No AI component - behavior in entity methods
|
||||
- Integrated animations for visual feedback
|
||||
- Simpler architecture overall
|
||||
|
||||
---
|
||||
|
||||
## Part 7: Creating the Interface
|
||||
|
||||
### Overview
|
||||
Add visual UI elements including health bars, message logs, and colored feedback for combat events.
|
||||
|
||||
### Core Components
|
||||
|
||||
#### 1. Health Bar
|
||||
```python
|
||||
class HealthBar:
|
||||
"""Health bar that reads entity HP directly"""
|
||||
def __init__(self, entity, pos=(10, 740), size=(200, 20)):
|
||||
self.entity = entity # Direct reference!
|
||||
|
||||
# Background (dark red)
|
||||
self.bg = mcrfpy.Frame(pos=pos, size=size)
|
||||
self.bg.fill_color = mcrfpy.Color(64, 16, 16)
|
||||
|
||||
# Foreground (green)
|
||||
self.fg = mcrfpy.Frame(pos=pos, size=size)
|
||||
self.fg.fill_color = mcrfpy.Color(0, 96, 0)
|
||||
|
||||
# Text overlay
|
||||
self.text = mcrfpy.Caption(
|
||||
pos=(pos[0] + 5, pos[1] + 2),
|
||||
text=f"HP: {entity.hp}/{entity.max_hp}"
|
||||
)
|
||||
|
||||
def update(self):
|
||||
"""Update based on entity's current HP"""
|
||||
ratio = self.entity.hp / self.entity.max_hp
|
||||
self.fg.w = int(self.bg.w * ratio)
|
||||
self.text.text = f"HP: {self.entity.hp}/{self.entity.max_hp}"
|
||||
|
||||
# Color changes at low health
|
||||
if ratio < 0.25:
|
||||
self.fg.fill_color = mcrfpy.Color(196, 16, 16) # Red
|
||||
elif ratio < 0.5:
|
||||
self.fg.fill_color = mcrfpy.Color(196, 196, 16) # Yellow
|
||||
```
|
||||
|
||||
#### 2. Message Log
|
||||
```python
|
||||
class MessageLog:
|
||||
"""Scrolling message log for combat feedback"""
|
||||
def __init__(self, pos=(10, 600), size=(400, 120), max_messages=6):
|
||||
self.frame = mcrfpy.Frame(pos=pos, size=size)
|
||||
self.messages = [] # List of (text, color) tuples
|
||||
self.captions = [] # Pre-allocated Caption pool
|
||||
|
||||
def add_message(self, text, color=None):
|
||||
"""Add message with optional color"""
|
||||
# Handle duplicate detection (x2, x3, etc.)
|
||||
# Update caption display
|
||||
```
|
||||
|
||||
#### 3. Color System
|
||||
```python
|
||||
class Colors:
|
||||
# Combat colors
|
||||
PLAYER_ATTACK = mcrfpy.Color(224, 224, 224)
|
||||
ENEMY_ATTACK = mcrfpy.Color(255, 192, 192)
|
||||
PLAYER_DEATH = mcrfpy.Color(255, 48, 48)
|
||||
ENEMY_DEATH = mcrfpy.Color(255, 160, 48)
|
||||
HEALTH_RECOVERED = mcrfpy.Color(0, 255, 0)
|
||||
```
|
||||
|
||||
### UI Layout
|
||||
- Health bar at bottom of screen
|
||||
- Message log above health bar
|
||||
- Direct binding to entity attributes
|
||||
- Real-time updates during gameplay
|
||||
|
||||
---
|
||||
|
||||
## Part 8: Items and Inventory
|
||||
|
||||
### Overview
|
||||
Implement items as entities, inventory management, and a hotbar-style UI for item usage.
|
||||
|
||||
### Core Components
|
||||
|
||||
#### 1. Item Entities
|
||||
```python
|
||||
class ItemEntity(mcrfpy.Entity):
|
||||
"""Base class for pickupable items"""
|
||||
def __init__(self, x, y, name, sprite, **kwargs):
|
||||
kwargs['sprite_index'] = sprite
|
||||
super().__init__(x=x, y=y, **kwargs)
|
||||
self.item_name = name
|
||||
self.blocks_movement = False
|
||||
self.item_type = "generic"
|
||||
|
||||
class HealingPotion(ItemEntity):
|
||||
"""Consumable healing item"""
|
||||
def __init__(self, x, y, healing_amount=4):
|
||||
super().__init__(x, y, "Healing Potion", sprite=33)
|
||||
self.healing_amount = healing_amount
|
||||
self.item_type = "consumable"
|
||||
|
||||
def use(self, user):
|
||||
"""Use the potion - returns (success, message)"""
|
||||
if hasattr(user, 'hp'):
|
||||
healed = min(self.healing_amount, user.max_hp - user.hp)
|
||||
if healed > 0:
|
||||
user.hp += healed
|
||||
return True, f"You heal {healed} HP!"
|
||||
```
|
||||
|
||||
#### 2. Inventory System
|
||||
```python
|
||||
class InventoryMixin:
|
||||
"""Mixin for entities with inventory"""
|
||||
def __init__(self, *args, capacity=10, **kwargs):
|
||||
super().__init__(*args, **kwargs)
|
||||
self.inventory = []
|
||||
self.inventory_capacity = capacity
|
||||
|
||||
def pickup_item(self, item):
|
||||
"""Pick up an item entity"""
|
||||
if len(self.inventory) >= self.inventory_capacity:
|
||||
return False, "Inventory full!"
|
||||
self.inventory.append(item)
|
||||
item.die() # Remove from grid
|
||||
return True, f"Picked up {item.item_name}."
|
||||
```
|
||||
|
||||
#### 3. Inventory UI
|
||||
```python
|
||||
class InventoryDisplay:
|
||||
"""Hotbar-style inventory display"""
|
||||
def __init__(self, entity, pos=(200, 700), slots=10):
|
||||
# Create slot frames and sprites
|
||||
# Number keys 1-9, 0 for slots
|
||||
# Highlight selected slot
|
||||
# Update based on entity.inventory
|
||||
```
|
||||
|
||||
### Key Features
|
||||
- Items exist as entities on the grid
|
||||
- Direct inventory attribute on player
|
||||
- Hotkey-based usage (1-9, 0)
|
||||
- Visual hotbar display
|
||||
- Item effects (healing, future: damage boost, etc.)
|
||||

|
||||
|
||||
---
|
||||
|
||||
## Testing Strategy
|
||||
|
||||
### Automated Tests
|
||||
```python
|
||||
# tests/test_part6_combat.py
|
||||
- Test damage calculation
|
||||
- Test death mechanics
|
||||
- Test combat messages
|
||||

---
|
||||
|
||||
## Risk Mitigation
|
||||
|
||||
### Potential Issues
|
||||
1. **Performance**: Many UI updates per frame
|
||||
- Solution: Update only on state changes
|
||||
|
||||
2. **Entity Collection Bugs**: Known segfault issues
|
||||
- Solution: Use index-based access when needed
|
||||
|
||||
3. **Animation Timing**: Complex with turn-based combat
|
||||
- Solution: Queue animations, process sequentially
|
||||
|
||||
### Fallback Options
|
||||
1. Start with console messages, add UI later
|
||||
2. Simple health numbers before bars
|
||||
3. Basic inventory list before hotbar
|
||||
|
||||
---
|
||||
|
||||
## Success Criteria
|
||||
|
||||
### Part 6
|
||||
- [x] Entities can have HP and take damage
|
||||
- [x] Death changes sprite and walkability
|
||||
- [x] Combat messages appear
|
||||
- [x] Player can kill enemies
|
||||
|
||||
### Part 7
|
||||
- [x] Health bar shows current/max HP
|
||||
- [x] Messages appear in scrolling log
|
||||
- [x] Colors differentiate message types
|
||||
- [x] UI updates in real-time
|
||||
|
||||
### Part 8
|
||||
- [x] Items can be picked up
|
||||
- [x] Inventory has capacity limit
|
||||
- [x] Items can be used/consumed
|
||||
- [x] Hotbar shows inventory items
|
||||
|
||||
---
|
||||
|
||||
## Notes for Implementation
|
||||
|
||||
1. **Keep It Simple**: Start with minimum viable features
|
||||
2. **Build Incrementally**: Test each component before integrating
|
||||
3. **Use Part 5**: Leverage existing entity interaction system
|
||||
4. **Document Well**: Clear comments for tutorial purposes
|
||||
5. **Visual Feedback**: McRogueFace excels at animations - use them!
|
||||
|
||||
---
|
||||
|
||||
## Comparison with Original Tutorial
|
||||
|
||||
### What We Keep
|
||||
- Same combat formula (power - defense)
|
||||
- Same entity stats (Player, Orc, Troll)
|
||||
- Same item types (healing potions to start)
|
||||
- Same UI elements (health bar, message log)
|
||||
|
||||
### What's Different
|
||||
- Direct inheritance instead of components
|
||||
- Integrated animations and visual effects
|
||||
- Hotbar inventory instead of menu
|
||||
- Built-in sound support
|
||||
- Cleaner architecture overall
|
||||
|
||||
### What's Better
|
||||
- More Pythonic with real inheritance
|
||||
- Better visual feedback
|
||||
- Smoother animations
|
||||
- Simpler to understand
|
||||
- Leverages McRogueFace's strengths
|
||||
|
||||
---
|
||||
|
||||
## Conclusion
|
||||
|
||||
This implementation plan leverages McRogueFace's support for Python entity inheritance to create a clean, intuitive tutorial series. By using direct attributes instead of components, we simplify the architecture while maintaining all the functionality of the original tutorial. The addition of animations, sound effects, and rich UI elements showcases McRogueFace's capabilities while keeping the code beginner-friendly.
|
||||
|
||||
The Tuesday delivery timeline is aggressive but achievable by focusing on core functionality first, then integration, then polish. The modular design allows for easy testing and incremental development.

# Simple TCOD Tutorial Part 1 - Drawing the player sprite and moving it around
|
||||
|
||||
This is Part 1 of the Simple TCOD Tutorial adapted for McRogueFace. It implements the sophisticated, refactored TCOD tutorial approach with professional architecture from day one.
|
||||
|
||||
## Running the Code
|
||||
|
||||
From your tutorial build directory (separate from the engine development build):
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
Note: The `scripts` folder should be a symlink to your `simple_tcod_tutorial` directory.
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
### Package Structure
|
||||
```
|
||||
simple_tcod_tutorial/
|
||||
├── main.py # Entry point - ties everything together
|
||||
├── game/ # Game package with proper separation
|
||||
│ ├── __init__.py
|
||||
│ ├── entity.py # Entity class - all game objects
|
||||
│ ├── engine.py # Engine class - game coordinator
|
||||
│ ├── actions.py # Action classes - command pattern
|
||||
│ └── input_handlers.py # Input handling - extensible system
|
||||
```
|
||||
|
||||
### Key Concepts Demonstrated
|
||||
|
||||
1. **Entity-Centric Design**
|
||||
- Everything in the game is an Entity
|
||||
- Entities have position, appearance, and behavior
|
||||
- Designed to scale to items, NPCs, and effects
|
||||
|
||||
2. **Action-Based Command Pattern**
|
||||
- All player actions are Action objects
|
||||
- Separates input from game logic
|
||||
- Enables undo, replay, and AI using same system
|
||||
|
||||
3. **Professional Input Handling**
|
||||
- BaseEventHandler for different input contexts
|
||||
- Complete movement key support (arrows, numpad, vi, WASD)
|
||||
- Ready for menus, targeting, and other modes
|
||||
|
||||
4. **Engine as Coordinator**
|
||||
- Manages game state without becoming a god object
|
||||
- Delegates to appropriate systems
|
||||
- Clean boundaries between systems
|
||||
|
||||
5. **Type Safety**
|
||||
- Full type annotations throughout
|
||||
- Forward references with TYPE_CHECKING
|
||||
- Modern Python best practices
|
||||
|
||||
## Differences from Vanilla McRogueFace Tutorial
|
||||
|
||||
### Removed
|
||||
- Animation system (instant movement instead)
|
||||
- Complex UI elements (focus on core mechanics)
|
||||
- Real-time features (pure turn-based)
|
||||
- Visual effects (camera following, smooth scrolling)
|
||||
- Entity color property (sprites handle appearance)
|
||||
|
||||
### Added
|
||||
- Complete movement key support
|
||||
- Professional architecture patterns
|
||||
- Proper package structure
|
||||
- Type annotations
|
||||
- Action-based design
|
||||
- Extensible handler system
|
||||
- Proper exit handling (Escape/Q actually quits)
|
||||
|
||||
### Adapted
|
||||
- Grid rendering with proper centering
|
||||
- Simplified entity system (position + sprite ID)
|
||||
- Using simple_tutorial.png sprite sheet (12 sprites)
|
||||
- Floor tiles using ground sprites (indices 1 and 2)
|
||||
- Direct sprite indices instead of character mapping
|
||||
|
||||
## Learning Objectives
|
||||
|
||||
Students completing Part 1 will understand:
|
||||
- How to structure a game project professionally
|
||||
- The value of entity-centric design
|
||||
- Command pattern for game actions
|
||||
- Input handling that scales to complex UIs
|
||||
- Type-driven development in Python
|
||||
- Architecture that grows without refactoring
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 2 will add:
|
||||
- The GameMap class for world representation
|
||||
- Tile-based movement and collision
|
||||
- Multiple entities in the world
|
||||
- Basic terrain (walls and floors)
|
||||
- Rendering order for entities
|
||||
|
||||
The architecture we've built in Part 1 makes these additions natural and painless, demonstrating the value of starting with good patterns.

This is Part 2 of the Simple TCOD Tutorial adapted for McRogueFace. Building on Part 1's foundation, we now introduce proper world representation and collision detection.
|
||||
|
||||
## Running the Code
|
||||
|
||||
From your tutorial build directory:
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
## New Architecture Components
|
||||
|
||||
### GameMap Class (`game/game_map.py`)
|
||||
The GameMap inherits from `mcrfpy.Grid` and adds:
|
||||
- **Tile Management**: Uses Grid's built-in point system with walkable property
|
||||
- **Entity Container**: Manages entity lifecycle with `add_entity()` and `remove_entity()`
|
||||
- **Spatial Queries**: `get_entities_at()`, `get_blocking_entity_at()`, `is_walkable()`
|
||||
- **Direct Integration**: Leverages Grid's walkable and tilesprite properties
|
||||
|
||||
### Tiles System (`game/tiles.py`)
|
||||
- **Simple Tile Types**: Using NamedTuple for clean tile definitions
|
||||
- **Tile Types**: Floor (walkable) and Wall (blocks movement)
|
||||
- **Grid Integration**: Maps directly to Grid point properties
|
||||
- **Future-Ready**: Includes transparency for FOV system in Part 4
|
||||
|
||||
### Entity Placement System
|
||||
- **Bidirectional References**: Entities know their map, maps track their entities
|
||||
- **`place()` Method**: Handles all bookkeeping when entities move between maps
|
||||
- **Lifecycle Management**: Automatic cleanup when entities leave maps
|
||||
|
||||
## Key Changes from Part 1
|
||||
|
||||
### Engine Updates
|
||||
- Replaced direct grid management with GameMap
|
||||
- Engine creates and configures the GameMap
|
||||
- Player is placed using the new `place()` method
|
||||
|
||||
### Movement System
|
||||
- MovementAction now checks `is_walkable()` before moving
|
||||
- Collision detection for both walls and blocking entities
|
||||
- Clean separation between validation and execution
|
||||
|
||||
### Visual Changes
|
||||
- Walls rendered as trees (sprite index 3)
|
||||
- Border of walls around the map edge
|
||||
- Floor tiles still use alternating pattern
|
||||
|
||||
## Architectural Benefits
|
||||
|
||||
### McRogueFace Integration
|
||||
- **No NumPy Dependency**: Uses Grid's native tile management
|
||||
- **Direct Walkability**: Grid points have built-in walkable property
|
||||
- **Unified System**: Visual and logical tile data in one place
|
||||
|
||||
### Separation of Concerns
|
||||
- **GameMap**: Knows about tiles and spatial relationships
|
||||
- **Engine**: Coordinates high-level game state
|
||||
- **Entity**: Manages its own lifecycle through `place()`
|
||||
- **Actions**: Validate their own preconditions
|
||||
|
||||
### Extensibility
|
||||
- Easy to add new tile types
|
||||
- Simple to implement different map generation
|
||||
- Ready for FOV, pathfinding, and complex queries
|
||||
- Entity system scales to items and NPCs
|
||||
|
||||
### Type Safety
|
||||
- TYPE_CHECKING imports prevent circular dependencies
|
||||
- Proper type hints throughout
|
||||
- Forward references maintain clean architecture
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 3 will add:
|
||||
- Procedural dungeon generation
|
||||
- Room and corridor creation
|
||||
- Multiple entities in the world
|
||||
- Foundation for enemy placement
|
||||
|
||||
The architecture established in Part 2 makes these additions straightforward, demonstrating the value of proper design from the beginning.

# Simple TCOD Tutorial Part 3 - Generating a dungeon
|
||||
|
||||
This is Part 3 of the Simple TCOD Tutorial adapted for McRogueFace. We now add procedural dungeon generation to create interesting, playable levels.
|
||||
|
||||
## Running the Code
|
||||
|
||||
From your tutorial build directory:
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
## New Features
|
||||
|
||||
### Procedural Generation Module (`game/procgen.py`)
|
||||
|
||||
This dedicated module demonstrates separation of concerns - dungeon generation logic is kept separate from the game map implementation.
|
||||
|
||||
#### RectangularRoom Class
|
||||
- **Clean Abstraction**: Represents a room with position and dimensions
|
||||
- **Utility Properties**:
|
||||
- `center` - Returns room center for connections
|
||||
- `inner` - Returns slice objects for efficient carving
|
||||
- **Intersection Detection**: `intersects()` method prevents overlapping rooms
|
||||
|
||||
#### Tunnel Generation
|
||||
- **L-Shaped Corridors**: Simple but effective connection method
|
||||
- **Iterator Pattern**: `tunnel_between()` yields coordinates efficiently
|
||||
- **Random Variation**: 50/50 chance of horizontal-first vs vertical-first
|
||||
|
||||
#### Dungeon Generation Algorithm
|
||||
```python
|
||||
def generate_dungeon(max_rooms, room_min_size, room_max_size,
|
||||
map_width, map_height, engine) -> GameMap:
|
||||
```
|
||||
- **Simple Algorithm**: Try to place random rooms, reject overlaps
|
||||
- **Automatic Connection**: Each room connects to the previous one
|
||||
- **Player Placement**: First room contains the player
|
||||
- **Entity-Centric**: Uses `player.place()` for proper lifecycle
|
||||
|
||||
## Architecture Benefits
|
||||
|
||||
### Modular Design
|
||||
- Generation logic separate from GameMap
|
||||
- Easy to swap algorithms later
|
||||
- Room class reusable for other features
|
||||
|
||||
### Forward Thinking
|
||||
- Engine parameter anticipates entity spawning
|
||||
- Room list available for future features
|
||||
- Iterator-based tunnel generation is memory efficient
|
||||
|
||||
### Clean Integration
|
||||
- Works seamlessly with existing entity placement
|
||||
- Respects GameMap's tile management
|
||||
- No special cases or hacks needed
|
||||
|
||||
## Visual Changes
|
||||
|
||||
- Map size increased to 80x45 for better dungeons
|
||||
- Zoom reduced to 1.0 to see more of the map
|
||||
- Random room layouts each time
|
||||
- Connected rooms and corridors
|
||||
|
||||
## Algorithm Details
|
||||
|
||||
The generation follows these steps:
|
||||
1. Start with a map filled with walls
|
||||
2. Try to place up to `max_rooms` rooms
|
||||
3. For each room attempt:
|
||||
- Generate random size and position
|
||||
- Check for intersections with existing rooms
|
||||
- If valid, carve out the room
|
||||
- Connect to previous room (if any)
|
||||
4. Place player in center of first room
|
||||
|
||||
This simple algorithm creates playable dungeons while being easy to understand and modify.
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 4 will add:
|
||||
- Field of View (FOV) system
|
||||
- Explored vs unexplored areas
|
||||
- Light and dark tile rendering
|
||||
- Torch radius around player
|
||||
|
||||
The modular dungeon generation makes it easy to add these visual features without touching the generation code.

# Part 4: Field of View and Exploration
|
||||
|
||||
## Overview
|
||||
|
||||
Part 4 introduces the Field of View (FOV) system, transforming our fully-visible dungeon into an atmospheric exploration experience. We leverage McRogueFace's built-in FOV capabilities and perspective system for efficient rendering.
|
||||
|
||||
## What's New in Part 4
|
||||
|
||||
### Field of View System
|
||||
- **FOV Calculation**: Using `Grid.compute_fov()` with configurable radius
|
||||
- **Perspective System**: Grid tracks which entity is the viewer
|
||||
- **Visibility States**: Unexplored (black), explored (dark), visible (lit)
|
||||
- **Automatic Updates**: FOV recalculates on player movement
|
||||
|
||||
### Implementation Details
|
||||
|
||||
#### FOV with McRogueFace's Grid
|
||||
|
||||
Unlike TCOD which uses numpy arrays for visibility tracking, McRogueFace's Grid has built-in FOV support:
|
||||
|
||||
```python
|
||||
# In GameMap.update_fov()
|
||||
self.compute_fov(viewer_x, viewer_y, radius, light_walls=True, algorithm=mcrfpy.FOV_BASIC)
|
||||
```
|
||||
|
||||
The Grid automatically:
|
||||
- Tracks which tiles have been explored
|
||||
- Applies appropriate color overlays (shroud, dark, light)
|
||||
- Updates entity visibility based on FOV
|
||||
|
||||
#### Perspective System
|
||||
|
||||
McRogueFace uses a perspective-based rendering approach:
|
||||
|
||||
```python
|
||||
# Set the viewer
|
||||
self.game_map.perspective = self.player
|
||||
|
||||
# Grid automatically renders from this entity's viewpoint
|
||||
```
|
||||
|
||||
This is more efficient than manually updating tile colors every turn.
|
||||
|
||||
#### Color Overlays
|
||||
|
||||
We define overlay colors but let the Grid handle application:
|
||||
|
||||
```python
|
||||
# In tiles.py
|
||||
SHROUD = mcrfpy.Color(0, 0, 0, 255) # Unexplored
|
||||
DARK = mcrfpy.Color(100, 100, 150, 128) # Explored but not visible
|
||||
LIGHT = mcrfpy.Color(255, 255, 255, 0) # Currently visible
|
||||
```
|
||||
|
||||
### Key Differences from TCOD
|
||||
|
||||
| TCOD Approach | McRogueFace Approach |
|
||||
|---------------|----------------------|
|
||||
| `visible` and `explored` numpy arrays | Grid's built-in FOV state |
|
||||
| Manual tile color switching | Automatic overlay system |
|
||||
| `tcod.map.compute_fov()` | `Grid.compute_fov()` |
|
||||
| Render conditionals for each tile | Perspective-based rendering |
|
||||
|
||||
### Movement and FOV Updates
|
||||
|
||||
The action system now updates FOV after player movement:
|
||||
|
||||
```python
|
||||
# In MovementAction.perform()
|
||||
if self.entity == engine.player:
|
||||
engine.update_fov()
|
||||
```
|
||||
|
||||
## Architecture Notes
|
||||
|
||||
### Why Grid Perspective?
|
||||
|
||||
The perspective system provides several benefits:
|
||||
1. **Efficiency**: No per-tile color updates needed
|
||||
2. **Flexibility**: Easy to switch viewpoints (for debugging or features)
|
||||
3. **Automatic**: Grid handles all rendering details
|
||||
4. **Clean**: Separates game logic from rendering concerns
|
||||
|
||||
### Entity Visibility
|
||||
|
||||
Entities automatically update their visibility state:
|
||||
|
||||
```python
|
||||
# After FOV calculation
|
||||
self.player.update_visibility()
|
||||
```
|
||||
|
||||
This ensures entities are only rendered when visible to the current perspective.
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `game/tiles.py`: Added FOV color overlay constants
|
||||
- `game/game_map.py`: Added `update_fov()` method
|
||||
- `game/engine.py`: Added FOV initialization and update method
|
||||
- `game/actions.py`: Update FOV after player movement
|
||||
- `main.py`: Updated part description
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 5 will add enemies to our dungeon, introducing:
|
||||
- Enemy entities with AI
|
||||
- Combat system
|
||||
- Turn-based gameplay
|
||||
- Health and damage
|
||||
|
||||
The FOV system will make enemies appear and disappear as you explore, adding tension and strategy to the gameplay.
|
||||
|
||||
## Learning Points
|
||||
|
||||
1. **Leverage Framework Features**: Use McRogueFace's built-in systems rather than reimplementing
|
||||
2. **Perspective-Based Design**: Think in terms of viewpoints, not global state
|
||||
3. **Automatic Systems**: Let the framework handle rendering details
|
||||
4. **Clean Integration**: FOV updates fit naturally into the action system
|
||||
|
||||
## Running Part 4
|
||||
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
You'll now see:
|
||||
- Black unexplored areas
|
||||
- Dark blue tint on previously seen areas
|
||||
- Full brightness only in your field of view
|
||||
- Smooth exploration as you move through the dungeon

# Part 5: Placing Enemies and Fighting Them
|
||||
|
||||
## Overview
|
||||
|
||||
Part 5 brings our dungeon to life with enemies! We add rats and spiders that populate the rooms, implement a combat system with melee attacks, and handle entity death by turning creatures into gravestones.
|
||||
|
||||
## What's New in Part 5
|
||||
|
||||
### Actor System
|
||||
- **Actor Class**: Extends Entity with combat stats (HP, defense, power)
|
||||
- **Combat Properties**: Health tracking, damage calculation, alive status
|
||||
- **Death Handling**: Entities become gravestones when killed
|
||||
|
||||
### Enemy Types
|
||||
Using our sprite sheet, we have two enemy types:
|
||||
- **Rat** (sprite 5): 10 HP, 0 defense, 3 power - Common enemy
|
||||
- **Spider** (sprite 4): 16 HP, 1 defense, 4 power - Tougher enemy
|
||||
|
||||
### Combat System
|
||||
|
||||
#### Bump-to-Attack
|
||||
When the player tries to move into an enemy:
|
||||
```python
|
||||
# In MovementAction.perform()
|
||||
target = engine.game_map.get_blocking_entity_at(dest_x, dest_y)
|
||||
if target:
|
||||
if self.entity == engine.player:
|
||||
from game.entity import Actor
|
||||
if isinstance(target, Actor) and target != engine.player:
|
||||
return MeleeAction(self.entity, self.dx, self.dy).perform(engine)
|
||||
```
|
||||
|
||||
#### Damage Calculation
|
||||
Simple formula with defense reduction:
|
||||
```python
|
||||
damage = attacker.power - target.defense
|
||||
```
|
||||
|
||||
#### Death System
|
||||
Dead entities become gravestones:
|
||||
```python
|
||||
def die(self) -> None:
|
||||
"""Handle death by becoming a gravestone."""
|
||||
self.sprite_index = 6 # Tombstone sprite
|
||||
self.blocks_movement = False
|
||||
self.name = f"Grave of {self.name}"
|
||||
```
|
||||
|
||||
### Entity Factories
|
||||
|
||||
Factory functions create pre-configured entities:
|
||||
```python
|
||||
def rat(x: int, y: int, texture: mcrfpy.Texture) -> Actor:
|
||||
return Actor(
|
||||
x=x, y=y,
|
||||
sprite_id=5, # Rat sprite
|
||||
texture=texture,
|
||||
name="Rat",
|
||||
hp=10, defense=0, power=3,
|
||||
)
|
||||
```
|
||||
|
||||
### Dungeon Population
|
||||
|
||||
Enemies are placed randomly in rooms:
|
||||
```python
|
||||
def place_entities(room, dungeon, max_monsters, texture):
|
||||
number_of_monsters = random.randint(0, max_monsters)
|
||||
|
||||
for _ in range(number_of_monsters):
|
||||
x = random.randint(room.x1 + 1, room.x2 - 1)
|
||||
y = random.randint(room.y1 + 1, room.y2 - 1)
|
||||
|
||||
if not any(entity.x == x and entity.y == y for entity in dungeon.entities):
|
||||
# 80% rats, 20% spiders
|
||||
if random.random() < 0.8:
|
||||
monster = entity_factories.rat(x, y, texture)
|
||||
else:
|
||||
monster = entity_factories.spider(x, y, texture)
|
||||
monster.place(x, y, dungeon)
|
||||
```
|
||||
|
||||
## Key Implementation Details
|
||||
|
||||
### FOV and Enemy Visibility
|
||||
Enemies are automatically shown/hidden by the FOV system:
|
||||
```python
|
||||
def update_fov(self) -> None:
|
||||
# Update visibility for all entities
|
||||
for entity in self.game_map.entities:
|
||||
entity.update_visibility()
|
||||
```
|
||||
|
||||
### Action System Extension
|
||||
The action system now handles combat:
|
||||
- **MovementAction**: Detects collision, triggers attack
|
||||
- **MeleeAction**: New action for melee combat
|
||||
- Actions remain decoupled from entity logic
|
||||
|
||||
### Gravestone System
|
||||
Instead of removing dead entities:
|
||||
- Sprite changes to tombstone (index 6)
|
||||
- Name changes to "Grave of [Name]"
|
||||
- No longer blocks movement
|
||||
- Remains visible as dungeon decoration
|
||||
|
||||
## Architecture Notes
|
||||
|
||||
### Why Actor Extends Entity?
|
||||
- Maintains entity hierarchy
|
||||
- Combat stats only for creatures
|
||||
- Future items/decorations won't have HP
|
||||
- Clean separation of concerns
|
||||
|
||||
### Why Factory Functions?
|
||||
- Centralized entity configuration
|
||||
- Easy to add new enemy types
|
||||
- Consistent stat management
|
||||
- Type-safe entity creation
|
||||
|
||||
### Combat in Actions
|
||||
Combat logic lives in actions, not entities:
|
||||
- Entities store stats
|
||||
- Actions perform combat
|
||||
- Clean separation of data and behavior
|
||||
- Extensible for future combat types
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `game/entity.py`: Added Actor class with combat stats and death handling
|
||||
- `game/entity_factories.py`: New module with entity creation functions
|
||||
- `game/actions.py`: Added MeleeAction for combat
|
||||
- `game/procgen.py`: Added enemy placement in rooms
|
||||
- `game/engine.py`: Updated to use Actor type and handle all entity visibility
|
||||
- `main.py`: Updated to use entity factories and Part 5 description
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 6 will enhance the combat experience with:
|
||||
- Health display UI
|
||||
- Game over conditions
|
||||
- Combat messages window
|
||||
- More strategic combat mechanics
|
||||
|
||||
## Learning Points
|
||||
|
||||
1. **Entity Specialization**: Use inheritance to add features to specific entity types
|
||||
2. **Factory Pattern**: Centralize object creation for consistency
|
||||
3. **State Transformation**: Dead entities become decorations, not deletions
|
||||
4. **Action Extensions**: Combat fits naturally into the action system
|
||||
5. **Automatic Systems**: FOV handles entity visibility without special code
|
||||
|
||||
## Running Part 5
|
||||
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
You'll now encounter rats and spiders as you explore! Walk into them to attack. Dead enemies become gravestones that mark your battles.
|
||||
|
||||
## Sprite Adaptations
|
||||
|
||||
Following our sprite sheet (`sprite_sheet.md`), we made these thematic changes:
|
||||
- Orcs → Rats (same stats, different sprite)
|
||||
- Trolls → Spiders (same stats, different sprite)
|
||||
- Corpses → Gravestones (all use same tombstone sprite)
|
||||
|
||||
The gameplay remains identical to the TCOD tutorial, just with different visual theming.

# Part 6: Doing (and Taking) Damage
|
||||
|
||||
## Overview
|
||||
|
||||
Part 6 transforms our basic combat into a complete gameplay loop with visual feedback, enemy AI, and win/lose conditions. We add a health bar, message log, enemy AI that pursues the player, and proper game over handling.
|
||||
|
||||
## What's New in Part 6
|
||||
|
||||
### User Interface Components
|
||||
|
||||
#### Health Bar
|
||||
A visual representation of the player's current health:
|
||||
```python
|
||||
class HealthBar:
|
||||
def create_ui(self) -> List[mcrfpy.UIDrawable]:
|
||||
# Dark red background
|
||||
self.background = mcrfpy.Frame(pos=(x, y), size=(width, height))
|
||||
self.background.fill_color = mcrfpy.Color(100, 0, 0, 255)
|
||||
|
||||
# Bright colored bar (green/yellow/red based on HP)
|
||||
self.bar = mcrfpy.Frame(pos=(x, y), size=(width, height))
|
||||
|
||||
# Text overlay showing HP numbers
|
||||
self.text = mcrfpy.Caption(pos=(x+5, y+2),
|
||||
text=f"HP: {hp}/{max_hp}")
|
||||
```
|
||||
|
||||
The bar changes color based on health percentage:
|
||||
- Green (>60% health)
|
||||
- Yellow (30-60% health)
|
||||
- Red (<30% health)
|
||||
|
||||
#### Message Log
|
||||
A scrolling combat log that replaces console print statements:
|
||||
```python
|
||||
class MessageLog:
|
||||
def __init__(self, max_messages: int = 5):
|
||||
self.messages: deque[str] = deque(maxlen=max_messages)
|
||||
|
||||
def add_message(self, message: str) -> None:
|
||||
self.messages.append(message)
|
||||
self.update_display()
|
||||
```
|
||||
|
||||
Messages include:
|
||||
- Combat actions ("Rat attacks Player for 3 hit points.")
|
||||
- Death notifications ("Spider is dead!")
|
||||
- Game state changes ("You have died! Press Escape to quit.")
|
||||
|
||||
### Enemy AI System
|
||||
|
||||
#### Basic AI Component
|
||||
Enemies now actively pursue and attack the player:
|
||||
```python
|
||||
class BasicAI:
|
||||
def take_turn(self, engine: Engine) -> None:
|
||||
distance = max(abs(dx), abs(dy)) # Chebyshev distance
|
||||
|
||||
if distance <= 1:
|
||||
# Adjacent: Attack!
|
||||
MeleeAction(self.entity, attack_dx, attack_dy).perform(engine)
|
||||
elif distance <= 6:
|
||||
# Can see player: Move closer
|
||||
MovementAction(self.entity, move_dx, move_dy).perform(engine)
|
||||
```
|
||||
|
||||
#### Turn-Based System
|
||||
After each player action, all enemies take their turn:
|
||||
```python
|
||||
def handle_enemy_turns(self) -> None:
|
||||
for entity in self.game_map.entities:
|
||||
if isinstance(entity, Actor) and entity.ai and entity.is_alive:
|
||||
entity.ai.take_turn(self)
|
||||
```
|
||||
|
||||
### Game Over Condition
|
||||
|
||||
When the player dies:
|
||||
1. Game state flag is set (`engine.game_over = True`)
|
||||
2. Player becomes a gravestone (sprite changes)
|
||||
3. Input is restricted (only Escape works)
|
||||
4. Death message appears in the message log
|
||||
|
||||
```python
|
||||
def handle_player_death(self) -> None:
|
||||
self.game_over = True
|
||||
self.message_log.add_message("You have died! Press Escape to quit.")
|
||||
```
|
||||
|
||||
## Architecture Improvements
|
||||
|
||||
### UI Module (`game/ui.py`)
|
||||
Separates UI concerns from game logic:
|
||||
- `MessageLog`: Manages combat messages
|
||||
- `HealthBar`: Displays player health
|
||||
- Clean interface for updating displays
|
||||
|
||||
### AI Module (`game/ai.py`)
|
||||
Encapsulates enemy behavior:
|
||||
- `BasicAI`: Simple pursue-and-attack behavior
|
||||
- Extensible for different AI types
|
||||
- Uses existing action system
|
||||
|
||||
### Turn Management
|
||||
Player actions trigger enemy turns:
|
||||
- Movement → Enemy turns
|
||||
- Attack → Enemy turns
|
||||
- Wait → Enemy turns
|
||||
- Maintains turn-based feel
|
||||
|
||||
## Key Implementation Details
|
||||
|
||||
### UI Updates
|
||||
Health bar updates occur:
|
||||
- After player takes damage
|
||||
- Automatically via `engine.update_ui()`
|
||||
- Color changes based on HP percentage
|
||||
|
||||
### Message Flow
|
||||
Combat messages follow this pattern:
|
||||
1. Action generates message text
|
||||
2. `engine.message_log.add_message(text)`
|
||||
3. Message appears in UI Caption
|
||||
4. Old messages scroll up
|
||||
|
||||
### AI Decision Making
|
||||
Basic AI uses simple rules:
|
||||
1. Check if player is adjacent → Attack
|
||||
2. Check if player is visible (within 6 tiles) → Move toward
|
||||
3. Otherwise → Do nothing
|
||||
|
||||
### Game State Management
|
||||
The `game_over` flag prevents:
|
||||
- Player movement
|
||||
- Player attacks
|
||||
- Player waiting
|
||||
- But allows Escape to quit
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `game/ui.py`: New module for UI components
|
||||
- `game/ai.py`: New module for enemy AI
|
||||
- `game/engine.py`: Added UI setup, enemy turns, game over handling
|
||||
- `game/entity.py`: Added AI component to Actor
|
||||
- `game/entity_factories.py`: Attached AI to enemies
|
||||
- `game/actions.py`: Integrated message log, added enemy turn triggers
|
||||
- `main.py`: Updated part description
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 7 will expand the user interface further with:
|
||||
- More detailed entity inspection
|
||||
- Possibly inventory display
|
||||
- Additional UI panels
|
||||
- Mouse interaction
|
||||
|
||||
## Learning Points
|
||||
|
||||
1. **UI Separation**: Keep UI logic separate from game logic
|
||||
2. **Component Systems**: AI as a component allows different behaviors
|
||||
3. **Turn-Based Flow**: Player action → Enemy reactions creates tactical gameplay
|
||||
4. **Visual Feedback**: Health bars and message logs improve player understanding
|
||||
5. **State Management**: Game over flag controls available actions
|
||||
|
||||
## Running Part 6
|
||||
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
You'll now see:
|
||||
- Health bar at the top showing your current HP
|
||||
- Message log at the bottom showing combat events
|
||||
- Enemies that chase you when you're nearby
|
||||
- Enemies that attack when adjacent
|
||||
- Death state when HP reaches 0
|
||||
|
||||
## Combat Strategy
|
||||
|
||||
With enemy AI active, combat becomes more tactical:
|
||||
- Enemies pursue when they see you
|
||||
- Fighting in corridors limits how many can attack
|
||||
- Running away is sometimes the best option
|
||||
- Health management becomes critical
|
||||
|
||||
The game now has a complete combat loop with clear win/lose conditions!

# Part 7: Creating the User Interface
|
||||
|
||||
## Overview
|
||||
|
||||
Part 7 significantly enhances the user interface, transforming our roguelike from a basic game into a more polished experience. We add mouse interaction, help displays, information panels, and better visual feedback systems.
|
||||
|
||||
## What's New in Part 7
|
||||
|
||||
### Mouse Interaction
|
||||
|
||||
#### Click-to-Inspect System
|
||||
Since McRogueFace doesn't have mouse motion events, we use click events to show entity information:
|
||||
```python
|
||||
def grid_click_handler(pixel_x, pixel_y, button, state):
|
||||
# Convert pixel coordinates to grid coordinates
|
||||
grid_x = int(pixel_x / (self.tile_size * self.zoom))
|
||||
grid_y = int(pixel_y / (self.tile_size * self.zoom))
|
||||
|
||||
# Update hover display for this position
|
||||
self.update_mouse_hover(grid_x, grid_y)
|
||||
```
|
||||
|
||||
Click displays show:
|
||||
- Entity names
|
||||
- Current HP for living creatures
|
||||
- Multiple entities if stacked (e.g., "Grave of Rat")
|
||||
|
||||
#### Mouse Handler Registration
|
||||
The click handler is registered as a local function to avoid issues with bound methods:
|
||||
```python
|
||||
# Use a local function instead of a bound method
|
||||
self.game_map.click = grid_click_handler
|
||||
```
|
||||
|
||||
### Help System
|
||||
|
||||
#### Toggle Help Display
|
||||
Press `?`, `H`, or `F1` to show/hide help:
|
||||
```python
|
||||
class HelpDisplay:
|
||||
def toggle(self) -> None:
|
||||
self.visible = not self.visible
|
||||
self.panel.frame.visible = self.visible
|
||||
```
|
||||
|
||||
The help panel includes:
|
||||
- Movement controls for all input methods
|
||||
- Combat instructions
|
||||
- Mouse usage tips
|
||||
- Gameplay strategies
|
||||
|
||||
### Information Panels
|
||||
|
||||
#### Player Stats Panel
|
||||
Always-visible panel showing:
|
||||
- Player name
|
||||
- Current/Max HP
|
||||
- Power and Defense stats
|
||||
- Current grid position
|
||||
|
||||
```python
|
||||
class InfoPanel:
|
||||
def create_ui(self, title: str) -> List[mcrfpy.Drawable]:
|
||||
# Semi-transparent background frame
|
||||
self.frame = mcrfpy.Frame(pos=(x, y), size=(width, height))
|
||||
self.frame.fill_color = mcrfpy.Color(20, 20, 40, 200)
|
||||
|
||||
# Title and content captions as children
|
||||
self.frame.children.append(self.title_caption)
|
||||
self.frame.children.append(self.content_caption)
|
||||
```
|
||||
|
||||
#### Reusable Panel System
|
||||
The `InfoPanel` class provides:
|
||||
- Titled panels with borders
|
||||
- Semi-transparent backgrounds
|
||||
- Easy content updates
|
||||
- Consistent visual style
|
||||
|
||||
### Enhanced UI Components
|
||||
|
||||
#### MouseHoverDisplay Class
|
||||
Manages tooltip-style hover information:
|
||||
- Follows mouse position
|
||||
- Shows/hides automatically
|
||||
- Offset to avoid cursor overlap
|
||||
- Multiple entity support
|
||||
|
||||
#### UI Module Organization
|
||||
Clean separation of UI components:
|
||||
- `MessageLog`: Combat messages
|
||||
- `HealthBar`: HP visualization
|
||||
- `MouseHoverDisplay`: Entity inspection
|
||||
- `InfoPanel`: Generic information display
|
||||
- `HelpDisplay`: Keyboard controls
|
||||
|
||||
## Architecture Improvements
|
||||
|
||||
### UI Composition
|
||||
Using McRogueFace's parent-child system:
|
||||
```python
|
||||
# Add caption as child of frame
|
||||
self.frame.children.append(self.text_caption)
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Automatic relative positioning
|
||||
- Group visibility control
|
||||
- Clean hierarchy
|
||||
|
||||
### Event Handler Extensions
|
||||
Input handler now manages:
|
||||
- Keyboard input (existing)
|
||||
- Mouse motion (new)
|
||||
- Mouse clicks (prepared for future)
|
||||
- UI toggles (help display)
|
||||
|
||||
### Dynamic Content Updates
|
||||
All UI elements support real-time updates:
|
||||
```python
|
||||
def update_stats_panel(self) -> None:
|
||||
stats_text = f"""Name: {self.player.name}
|
||||
HP: {self.player.hp}/{self.player.max_hp}
|
||||
Power: {self.player.power}
|
||||
Defense: {self.player.defense}"""
|
||||
self.stats_panel.update_content(stats_text)
|
||||
```
|
||||
|
||||
## Key Implementation Details
|
||||
|
||||
### Mouse Coordinate Conversion
|
||||
Pixel to grid conversion:
|
||||
```python
|
||||
grid_x = int(x / (self.engine.tile_size * self.engine.zoom))
|
||||
grid_y = int(y / (self.engine.tile_size * self.engine.zoom))
|
||||
```
|
||||
|
||||
### Visibility Management
|
||||
UI elements can be toggled:
|
||||
- Help panel starts hidden
|
||||
- Mouse hover hides when not over entities
|
||||
- Panels can be shown/hidden dynamically
|
||||
|
||||
### Color and Transparency
|
||||
UI uses semi-transparent overlays:
|
||||
- Panel backgrounds: `Color(20, 20, 40, 200)`
|
||||
- Hover tooltips: `Color(255, 255, 200, 255)`
|
||||
- Borders and outlines for readability
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `game/ui.py`: Added MouseHoverDisplay, InfoPanel, HelpDisplay classes
|
||||
- `game/engine.py`: Integrated new UI components, mouse hover handling
|
||||
- `game/input_handlers.py`: Added mouse motion handling, help toggle
|
||||
- `main.py`: Registered mouse handlers, updated part description
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 8 will add items and inventory:
|
||||
- Collectible items (potions, equipment)
|
||||
- Inventory management UI
|
||||
- Item usage mechanics
|
||||
- Equipment system
|
||||
|
||||
## Learning Points
|
||||
|
||||
1. **UI Composition**: Use parent-child relationships for complex UI
|
||||
2. **Event Delegation**: Separate input handling from UI updates
|
||||
3. **Information Layers**: Multiple UI systems can coexist (hover, panels, help)
|
||||
4. **Visual Polish**: Small touches like transparency and borders improve UX
|
||||
5. **Reusable Components**: Generic panels can be specialized for different uses
|
||||
|
||||
## Running Part 7
|
||||
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
New features to try:
|
||||
- Click on entities to see their details
|
||||
- Press ? or H to toggle help display
|
||||
- Watch the stats panel update as you take damage
|
||||
- See entity HP in hover tooltips
|
||||
- Notice the visual polish in UI panels
|
||||
|
||||
## UI Design Principles
|
||||
|
||||
### Consistency
|
||||
- All panels use similar visual style
|
||||
- Consistent color scheme
|
||||
- Uniform text sizing
|
||||
|
||||
### Non-Intrusive
|
||||
- Semi-transparent panels don't block view
|
||||
- Hover info appears near cursor
|
||||
- Help can be toggled off
|
||||
|
||||
### Information Hierarchy
|
||||
- Critical info (health) always visible
|
||||
- Contextual info (hover) on demand
|
||||
- Help info toggleable
|
||||
|
||||
The UI now provides a professional feel while maintaining the roguelike aesthetic!

# Part 8: Items and Inventory
|
||||
|
||||
## Overview
|
||||
|
||||
Part 8 transforms our roguelike into a proper loot-driven game by adding items that can be collected, managed, and used. We implement a flexible inventory system with capacity limits, create consumable items like healing potions, and build UI for inventory management.
|
||||
|
||||
## What's New in Part 8
|
||||
|
||||
### Parent-Child Entity Architecture
|
||||
|
||||
#### Flexible Entity Ownership
|
||||
Entities now have parent containers, allowing them to exist in different contexts:
|
||||
```python
|
||||
class Entity(mcrfpy.Entity):
|
||||
def __init__(self, parent: Optional[Union[GameMap, Inventory]] = None):
|
||||
self.parent = parent
|
||||
|
||||
@property
|
||||
def gamemap(self) -> Optional[GameMap]:
|
||||
"""Get the GameMap through the parent chain"""
|
||||
if isinstance(self.parent, Inventory):
|
||||
return self.parent.gamemap
|
||||
return self.parent
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Items can exist in the world or in inventories
|
||||
- Clean ownership transfer when picking up/dropping
|
||||
- Automatic visibility management
|
||||
|
||||
### Inventory System
|
||||
|
||||
#### Container-Based Design
|
||||
The inventory acts like a specialized entity container:
|
||||
```python
|
||||
class Inventory:
|
||||
def __init__(self, capacity: int):
|
||||
self.capacity = capacity
|
||||
self.items: List[Item] = []
|
||||
self.parent: Optional[Actor] = None
|
||||
|
||||
def add_item(self, item: Item) -> None:
|
||||
if len(self.items) >= self.capacity:
|
||||
raise Impossible("Your inventory is full.")
|
||||
|
||||
# Transfer ownership
|
||||
self.items.append(item)
|
||||
item.parent = self
|
||||
item.visible = False # Hide from map
|
||||
```
|
||||
|
||||
Features:
|
||||
- Capacity limits (26 items for letter selection)
|
||||
- Clean item transfer between world and inventory
|
||||
- Automatic visual management
|
||||
|
||||
### Item System
|
||||
|
||||
#### Item Entity Class
|
||||
Items are entities with consumable components:
|
||||
```python
|
||||
class Item(Entity):
|
||||
def __init__(self, consumable: Optional = None):
|
||||
super().__init__(blocks_movement=False)
|
||||
self.consumable = consumable
|
||||
if consumable:
|
||||
consumable.parent = self
|
||||
```
|
||||
|
||||
#### Consumable Components
|
||||
Modular system for item effects:
|
||||
```python
|
||||
class HealingConsumable(Consumable):
|
||||
def activate(self, action: ItemAction) -> None:
|
||||
if consumer.hp >= consumer.max_hp:
|
||||
raise Impossible("You are already at full health.")
|
||||
|
||||
amount_recovered = min(self.amount, consumer.max_hp - consumer.hp)
|
||||
consumer.hp += amount_recovered
|
||||
self.consume() # Remove item after use
|
||||
```
|
||||
|
||||
### Exception-Driven Feedback
|
||||
|
||||
#### Clean Error Handling
|
||||
Using exceptions for user feedback:
|
||||
```python
|
||||
class Impossible(Exception):
|
||||
"""Action cannot be performed"""
|
||||
pass
|
||||
|
||||
class PickupAction(Action):
|
||||
def perform(self, engine: Engine) -> None:
|
||||
if not items_here:
|
||||
raise Impossible("There is nothing here to pick up.")
|
||||
|
||||
try:
|
||||
inventory.add_item(item)
|
||||
engine.message_log.add_message(f"You picked up the {item.name}!")
|
||||
except Impossible as e:
|
||||
engine.message_log.add_message(str(e))
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Consistent error messaging
|
||||
- Clean control flow
|
||||
- Centralized feedback handling
|
||||
|
||||
### Inventory UI
|
||||
|
||||
#### Modal Inventory Screen
|
||||
Interactive inventory management:
|
||||
```python
|
||||
class InventoryEventHandler(BaseEventHandler):
|
||||
def create_ui(self) -> None:
|
||||
# Semi-transparent background
|
||||
self.background = mcrfpy.Frame(pos=(100, 100), size=(400, 400))
|
||||
self.background.fill_color = mcrfpy.Color(0, 0, 0, 200)
|
||||
|
||||
# List items with letter keys
|
||||
for i, item in enumerate(inventory.items):
|
||||
item_caption = mcrfpy.Caption(
|
||||
pos=(20, 80 + i * 20),
|
||||
text=f"{chr(ord('a') + i)}) {item.name}"
|
||||
)
|
||||
```
|
||||
|
||||
Features:
|
||||
- Letter-based selection (a-z)
|
||||
- Separate handlers for use/drop
|
||||
- ESC to cancel
|
||||
- Visual feedback
|
||||
|
||||
### Enhanced Actions
|
||||
|
||||
#### Item Actions
|
||||
New actions for item management:
|
||||
```python
|
||||
class PickupAction(Action):
|
||||
"""Pick up items at current location"""
|
||||
|
||||
class ItemAction(Action):
|
||||
"""Base for item usage actions"""
|
||||
|
||||
class DropAction(ItemAction):
|
||||
"""Drop item from inventory"""
|
||||
```
|
||||
|
||||
Each action:
|
||||
- Self-validates
|
||||
- Provides feedback
|
||||
- Triggers enemy turns
|
||||
|
||||
## Architecture Improvements
|
||||
|
||||
### Component Relationships
|
||||
Parent-based component system:
|
||||
```python
|
||||
# Components know their parent
|
||||
consumable.parent = item
|
||||
item.parent = inventory
|
||||
inventory.parent = actor
|
||||
actor.parent = gamemap
|
||||
gamemap.engine = engine
|
||||
```
|
||||
|
||||
Benefits:
|
||||
- Access to game context from any component
|
||||
- Clean ownership transfer
|
||||
- Simplified entity lifecycle
|
||||
|
||||
### Input Handler States
|
||||
Modal UI through handler switching:
|
||||
```python
|
||||
# Main game
|
||||
engine.current_handler = MainGameEventHandler(engine)
|
||||
|
||||
# Open inventory
|
||||
engine.current_handler = InventoryActivateHandler(engine)
|
||||
|
||||
# Back to game
|
||||
engine.current_handler = MainGameEventHandler(engine)
|
||||
```
|
||||
|
||||
### Entity Lifecycle Management
|
||||
Proper creation and cleanup:
|
||||
```python
|
||||
# Item spawning
|
||||
item = entity_factories.health_potion(x, y, texture)
|
||||
item.place(x, y, dungeon)
|
||||
|
||||
# Pickup
|
||||
inventory.add_item(item) # Removes from map
|
||||
|
||||
# Drop
|
||||
inventory.drop(item) # Returns to map
|
||||
|
||||
# Death
|
||||
actor.die() # Drops all items
|
||||
```
|
||||
|
||||
## Key Implementation Details
|
||||
|
||||
### Visibility Management
|
||||
Items hide/show based on container:
|
||||
```python
|
||||
def add_item(self, item):
|
||||
item.visible = False # Hide when in inventory
|
||||
|
||||
def drop(self, item):
|
||||
item.visible = True # Show when on map
|
||||
```
|
||||
|
||||
### Inventory Capacity
|
||||
Limited to alphabet keys:
|
||||
```python
|
||||
if len(inventory.items) >= 26:
|
||||
raise Impossible("Your inventory is full.")
|
||||
```
|
||||
|
||||
### Item Generation
|
||||
Procedural item placement:
|
||||
```python
|
||||
def place_entities(room, dungeon, max_monsters, max_items, texture):
|
||||
# Place 0-2 items per room
|
||||
number_of_items = random.randint(0, max_items)
|
||||
|
||||
for _ in range(number_of_items):
|
||||
if space_available:
|
||||
item = entity_factories.health_potion(x, y, texture)
|
||||
item.place(x, y, dungeon)
|
||||
```
|
||||
|
||||
## Files Modified
|
||||
|
||||
- `game/entity.py`: Added parent system, Item class, inventory to Actor
|
||||
- `game/inventory.py`: New inventory container system
|
||||
- `game/consumable.py`: New consumable component system
|
||||
- `game/exceptions.py`: New Impossible exception
|
||||
- `game/actions.py`: Added PickupAction, ItemAction, DropAction
|
||||
- `game/input_handlers.py`: Added InventoryEventHandler classes
|
||||
- `game/engine.py`: Added current_handler, inventory UI methods
|
||||
- `game/procgen.py`: Added item generation
|
||||
- `game/entity_factories.py`: Added health_potion factory
|
||||
- `game/ui.py`: Updated help text with inventory controls
|
||||
- `main.py`: Updated to Part 8, handler management
|
||||
|
||||
## What's Next
|
||||
|
||||
Part 9 will add ranged attacks and targeting:
|
||||
- Targeting UI for selecting enemies
|
||||
- Ranged damage items (lightning staff)
|
||||
- Area-of-effect items (fireball staff)
|
||||
- Confusion effects
|
||||
|
||||
## Learning Points
|
||||
|
||||
1. **Container Architecture**: Entity ownership through parent relationships
|
||||
2. **Component Systems**: Modular, reusable components with parent references
|
||||
3. **Exception Handling**: Clean error propagation and user feedback
|
||||
4. **Modal UI**: State-based input handling for different screens
|
||||
5. **Item Systems**: Flexible consumable architecture for varied effects
|
||||
6. **Lifecycle Management**: Proper entity creation, transfer, and cleanup
|
||||
|
||||
## Running Part 8
|
||||
|
||||
```bash
|
||||
cd simple_tcod_tutorial/build
|
||||
./mcrogueface scripts/main.py
|
||||
```
|
||||
|
||||
New features to try:
|
||||
- Press G to pick up healing potions
|
||||
- Press I to open inventory and use items
|
||||
- Press O to drop items from inventory
|
||||
- Heal yourself when injured in combat
|
||||
- Manage limited inventory space (26 slots)
|
||||
- Items drop from dead enemies
|
||||
|
||||
## Design Principles
|
||||
|
||||
### Flexibility Through Composition
|
||||
- Items gain behavior through consumable components
|
||||
- Easy to add new item types
|
||||
- Reusable effect system
|
||||
|
||||
### Clean Ownership Transfer
|
||||
- Entities always have clear parent
|
||||
- Automatic visibility management
|
||||
- No orphaned entities
|
||||
|
||||
### User-Friendly Feedback
|
||||
- Clear error messages
|
||||
- Consistent UI patterns
|
||||
- Intuitive controls
|
||||
|
||||
The inventory system provides the foundation for equipment, spells, and complex item interactions in future parts!

McRogueFace Tutorial - Part 5: Entity Interactions
|
||||
|
||||
This tutorial builds on Part 4 by adding:
|
||||
- Entity class hierarchy (PlayerEntity, EnemyEntity, BoulderEntity, ButtonEntity)
|
||||
- Non-blocking movement animations with destination tracking
|
||||
- Bump interactions (combat, pushing)
|
||||
- Step-on interactions (buttons, doors)
|
||||
- Concurrent enemy AI with smooth animations
|
||||
|
||||
Key concepts:
|
||||
- Entities inherit from mcrfpy.Entity for proper C++/Python integration
|
||||
- Logic operates on destination positions during animations
|
||||
- Player input is processed immediately, not blocked by animations

# Part 0 - Setting Up McRogueFace
|
||||
|
||||
Welcome to the McRogueFace Roguelike Tutorial! This tutorial will teach you how to create a complete roguelike game using the McRogueFace game engine. Unlike traditional Python libraries, McRogueFace is a complete, portable game engine that includes everything you need to make and distribute games.
|
||||
|
||||
## What is McRogueFace?
|
||||
|
||||
McRogueFace is a high-performance game engine with Python scripting support. Think of it like Unity or Godot, but specifically designed for roguelikes and 2D games. It includes:
|
||||
|
||||
- A complete Python 3.12 runtime (no installation needed!)
|
||||
- High-performance C++ rendering and entity management
|
||||
- Built-in UI components and scene management
|
||||
- Integrated audio system
|
||||
- Professional sprite-based graphics
|
||||
- Easy distribution - your players don't need Python installed!
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Before starting this tutorial, you should:
|
||||
|
||||
- Have basic Python knowledge (variables, functions, classes)
|
||||
- Be comfortable editing text files
|
||||
- Have a text editor (VS Code, Sublime Text, Notepad++, etc.)
|
||||
|
||||
That's it! Unlike other roguelike tutorials, you don't need Python installed - McRogueFace includes everything.
|
||||
|
||||
## Getting McRogueFace
|
||||
|
||||
### Step 1: Download the Engine
|
||||
|
||||
1. Visit the McRogueFace releases page
|
||||
2. Download the version for your operating system:
|
||||
- `McRogueFace-Windows.zip` for Windows
|
||||
- `McRogueFace-MacOS.zip` for macOS
|
||||
- `McRogueFace-Linux.zip` for Linux
|
||||
|
||||
### Step 2: Extract the Archive
|
||||
|
||||
Extract the downloaded archive to a folder where you want to develop your game. You should see this structure:
|
||||
|
||||
```
|
||||
McRogueFace/
|
||||
├── mcrogueface (or mcrogueface.exe on Windows)
|
||||
├── scripts/
|
||||
│ └── game.py
|
||||
├── assets/
|
||||
│ ├── sprites/
|
||||
│ ├── fonts/
|
||||
│ └── audio/
|
||||
└── lib/
|
||||
```
|
||||
|
||||
### Step 3: Run the Engine
|
||||
|
||||
Run the McRogueFace executable:
|
||||
|
||||
- **Windows**: Double-click `mcrogueface.exe`
|
||||
- **Mac/Linux**: Open a terminal in the folder and run `./mcrogueface`
|
||||
|
||||
You should see a window open with the default McRogueFace demo. This shows the engine is working correctly!
|
||||
|
||||
## Your First McRogueFace Script
|
||||
|
||||
Let's modify the engine to display "Hello Roguelike!" instead of the default demo.
|
||||
|
||||
### Step 1: Open game.py
|
||||
|
||||
Open `scripts/game.py` in your text editor. You'll see the default demo code. Replace it entirely with:
|
||||
|
||||
```python
|
||||
import mcrfpy
|
||||
|
||||
# Create a new scene called "hello"
|
||||
mcrfpy.createScene("hello")
|
||||
|
||||
# Switch to our new scene
|
||||
mcrfpy.setScene("hello")
|
||||
|
||||
# Get the UI container for our scene
|
||||
ui = mcrfpy.sceneUI("hello")
|
||||
|
||||
# Create a text caption
|
||||
caption = mcrfpy.Caption("Hello Roguelike!", 400, 300)
|
||||
caption.font_size = 32
|
||||
caption.fill_color = mcrfpy.Color(255, 255, 255) # White text
|
||||
|
||||
# Add the caption to our scene
|
||||
ui.append(caption)
|
||||
|
||||
# Create a smaller instruction caption
|
||||
instruction = mcrfpy.Caption("Press ESC to exit", 400, 350)
|
||||
instruction.font_size = 16
|
||||
instruction.fill_color = mcrfpy.Color(200, 200, 200) # Light gray
|
||||
ui.append(instruction)
|
||||
|
||||
# Set up a simple key handler
|
||||
def handle_keys(key, state):
|
||||
if state == "start" and key == "Escape":
|
||||
mcrfpy.setScene(None) # This exits the game
|
||||
|
||||
mcrfpy.keypressScene(handle_keys)
|
||||
|
||||
print("Hello Roguelike is running!")
|
||||
```
|
||||
|
||||
### Step 2: Save and Run
|
||||
|
||||
1. Save the file
|
||||
2. If McRogueFace is still running, it will automatically reload!
|
||||
3. If not, run the engine again
|
||||
|
||||
You should now see "Hello Roguelike!" displayed in the window.
|
||||
|
||||
### Step 3: Understanding the Code
|
||||
|
||||
Let's break down what we just wrote:
|
||||
|
||||
1. **Import mcrfpy**: This is McRogueFace's Python API
|
||||
2. **Create a scene**: Scenes are like game states (menu, gameplay, inventory, etc.)
|
||||
3. **UI elements**: We create Caption objects for text display
|
||||
4. **Colors**: McRogueFace uses RGB colors (0-255 for each component)
|
||||
5. **Input handling**: We set up a callback for keyboard input
|
||||
6. **Scene switching**: Setting the scene to None exits the game
|
||||
|
||||
## Key Differences from Pure Python Development
|
||||
|
||||
### The Game Loop
|
||||
|
||||
Unlike typical Python scripts, McRogueFace runs your code inside its game loop:
|
||||
|
||||
1. The engine starts and loads `scripts/game.py`
|
||||
2. Your script sets up scenes, UI elements, and callbacks
|
||||
3. The engine runs at 60 FPS, handling rendering and input
|
||||
4. Your callbacks are triggered by game events
|
||||
|
||||
### Hot Reloading
|
||||
|
||||
McRogueFace can reload your scripts while running! Just save your changes and the engine will reload automatically. This makes development incredibly fast.
|
||||
|
||||
### Asset Pipeline
|
||||
|
||||
McRogueFace includes a complete asset system:
|
||||
|
||||
- **Sprites**: Place images in `assets/sprites/`
|
||||
- **Fonts**: TrueType fonts in `assets/fonts/`
|
||||
- **Audio**: Sound effects and music in `assets/audio/`
|
||||
|
||||
We'll explore these in later lessons.
|
||||
|
||||
## Testing Your Setup
|
||||
|
||||
Let's create a more interactive test to ensure everything is working properly:
|
||||
|
||||
```python
|
||||
import mcrfpy
|
||||
|
||||
# Create our test scene
|
||||
mcrfpy.createScene("test")
|
||||
mcrfpy.setScene("test")
|
||||
ui = mcrfpy.sceneUI("test")
|
||||
|
||||
# Create a background frame
|
||||
background = mcrfpy.Frame(0, 0, 1024, 768)
|
||||
background.fill_color = mcrfpy.Color(20, 20, 30) # Dark blue-gray
|
||||
ui.append(background)
|
||||
|
||||
# Title text
|
||||
title = mcrfpy.Caption("McRogueFace Setup Test", 512, 100)
|
||||
title.font_size = 36
|
||||
title.fill_color = mcrfpy.Color(255, 255, 100) # Yellow
|
||||
ui.append(title)
|
||||
|
||||
# Status text that will update
|
||||
status_text = mcrfpy.Caption("Press any key to test input...", 512, 300)
|
||||
status_text.font_size = 20
|
||||
status_text.fill_color = mcrfpy.Color(200, 200, 200)
|
||||
ui.append(status_text)
|
||||
|
||||
# Instructions
|
||||
instructions = [
|
||||
"Arrow Keys: Test movement input",
|
||||
"Space: Test action input",
|
||||
"Mouse Click: Test mouse input",
|
||||
"ESC: Exit"
|
||||
]
|
||||
|
||||
y_offset = 400
|
||||
for instruction in instructions:
|
||||
inst_caption = mcrfpy.Caption(instruction, 512, y_offset)
|
||||
inst_caption.font_size = 16
|
||||
inst_caption.fill_color = mcrfpy.Color(150, 150, 150)
|
||||
ui.append(inst_caption)
|
||||
y_offset += 30
|
||||
|
||||
# Input handler
|
||||
def handle_input(key, state):
|
||||
if state != "start":
|
||||
return
|
||||
|
||||
if key == "Escape":
|
||||
mcrfpy.setScene(None)
|
||||
else:
|
||||
status_text.text = f"You pressed: {key}"
|
||||
status_text.fill_color = mcrfpy.Color(100, 255, 100) # Green
|
||||
|
||||
# Set up input handling
|
||||
mcrfpy.keypressScene(handle_input)
|
||||
|
||||
print("Setup test is running! Try pressing different keys.")
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Engine Won't Start
|
||||
|
||||
- **Windows**: Make sure you extracted all files, not just the .exe
|
||||
- **Mac**: You may need to right-click and select "Open" the first time
|
||||
- **Linux**: Make sure the file is executable: `chmod +x mcrogueface`
|
||||
|
||||
### Scripts Not Loading
|
||||
|
||||
- Ensure your script is named exactly `game.py` in the `scripts/` folder
|
||||
- Check the console output for Python errors
|
||||
- Make sure you're using Python 3 syntax
|
||||
|
||||
### Performance Issues
|
||||
|
||||
- McRogueFace should run smoothly at 60 FPS
|
||||
- If not, check if your graphics drivers are updated
|
||||
- The engine shows FPS in the window title
|
||||
|
||||
## What's Next?
|
||||
|
||||
Congratulations! You now have McRogueFace set up and running. You've learned:
|
||||
|
||||
- How to download and run the McRogueFace engine
|
||||
- The basic structure of a McRogueFace project
|
||||
- How to create scenes and UI elements
|
||||
- How to handle keyboard input
|
||||
- The development workflow with hot reloading
|
||||
|
||||
In Part 1, we'll create our player character and implement movement. We'll explore McRogueFace's entity system and learn how to create a game world.
|
||||
|
||||
## Why McRogueFace?
|
||||
|
||||
Before we continue, let's highlight why McRogueFace is excellent for roguelike development:
|
||||
|
||||
1. **No Installation Hassles**: Your players just download and run - no Python needed!
|
||||
2. **Professional Performance**: C++ engine core means smooth gameplay even with hundreds of entities
|
||||
3. **Built-in Features**: UI, audio, scenes, and animations are already there
|
||||
4. **Easy Distribution**: Just zip your game folder and share it
|
||||
5. **Rapid Development**: Hot reloading and Python scripting for quick iteration
|
||||

# Part 1 - Drawing the '@' Symbol and Moving It Around
|
||||
|
||||
In Part 0, we set up McRogueFace and created a simple "Hello Roguelike" scene. Now it's time to create the foundation of our game: a player character that can move around the screen.
|
||||
|
||||
In traditional roguelikes, the player is represented by the '@' symbol. We'll honor that tradition while taking advantage of McRogueFace's powerful sprite-based rendering system.
|
||||
|
||||
## Understanding McRogueFace's Architecture
|
||||
|
||||
Before we dive into code, let's understand two key concepts in McRogueFace:
|
||||
|
||||
### Grid - The Game World
|
||||
|
||||
A `Grid` represents your game world. It's a 2D array of tiles where each tile can be:
|
||||
- **Walkable or not** (for collision detection)
|
||||
- **Transparent or not** (for field of view, which we'll cover later)
|
||||
- **Have a visual appearance** (sprite index and color)
|
||||
|
||||
Think of the Grid as the dungeon floor, walls, and other static elements.
|
||||
|
||||
### Entity - Things That Move
|
||||
|
||||
An `Entity` represents anything that can move around on the Grid:
|
||||
- The player character
|
||||
- Monsters
|
||||
- Items (if you want them to be thrown or moved)
|
||||
- Projectiles
|
||||
|
||||
Entities exist "on top of" the Grid and automatically handle smooth movement animation between tiles.
|
||||
|
||||
## Creating Our Game World
|
||||
|
||||
Let's start by creating a simple room for our player to move around in. Create a new `game.py`:
|
||||
|
||||
```python
|
||||
import mcrfpy
|
||||
|
||||
# Define some constants for our tile types
|
||||
FLOOR_TILE = 0
|
||||
WALL_TILE = 1
|
||||
PLAYER_SPRITE = 2
|
||||
|
||||
# Window configuration
|
||||
mcrfpy.createScene("game")
|
||||
mcrfpy.setScene("game")
|
||||
|
||||
# Configure window properties
|
||||
window = mcrfpy.Window.get()
|
||||
window.title = "McRogueFace Roguelike - Part 1"
|
||||
|
||||
# Get the UI container for our scene
|
||||
ui = mcrfpy.sceneUI("game")
|
||||
|
||||
# Create a dark background
|
||||
background = mcrfpy.Frame(0, 0, 1024, 768)
|
||||
background.fill_color = mcrfpy.Color(0, 0, 0)
|
||||
ui.append(background)
|
||||
```
|
||||
|
||||
Now we need to set up our tileset. For this tutorial, we'll use ASCII-style sprites. McRogueFace comes with a built-in ASCII tileset:
|
||||
|
||||
```python
|
||||
# Load the ASCII tileset
|
||||
# This tileset has characters mapped to sprite indices
|
||||
# For example: @ = 64, # = 35, . = 46
|
||||
tileset = mcrfpy.Texture("assets/sprites/ascii_tileset.png", 16, 16)
|
||||
|
||||
# Create the game grid
|
||||
# 50x30 tiles is a good size for a roguelike
|
||||
GRID_WIDTH = 50
|
||||
GRID_HEIGHT = 30
|
||||
|
||||
grid = mcrfpy.Grid(grid_x=GRID_WIDTH, grid_y=GRID_HEIGHT, texture=tileset)
|
||||
grid.position = (100, 100) # Position on screen
|
||||
grid.size = (800, 480) # Size in pixels
|
||||
|
||||
# Add the grid to our UI
|
||||
ui.append(grid)
|
||||
```
|
||||
|
||||
## Initializing the Game World
|
||||
|
||||
Now let's fill our grid with a simple room:
|
||||
|
||||
```python
|
||||
def create_room():
|
||||
"""Create a room with walls around the edges"""
|
||||
# Fill everything with floor tiles first
|
||||
for y in range(GRID_HEIGHT):
|
||||
for x in range(GRID_WIDTH):
|
||||
cell = grid.at(x, y)
|
||||
cell.walkable = True
|
||||
cell.transparent = True
|
||||
cell.sprite_index = 46 # '.' character
|
||||
cell.color = mcrfpy.Color(50, 50, 50) # Dark gray floor
|
||||
|
||||
# Create walls around the edges
|
||||
for x in range(GRID_WIDTH):
|
||||
# Top wall
|
||||
cell = grid.at(x, 0)
|
||||
cell.walkable = False
|
||||
cell.transparent = False
|
||||
cell.sprite_index = 35 # '#' character
|
||||
cell.color = mcrfpy.Color(100, 100, 100) # Gray walls
|
||||
|
||||
# Bottom wall
|
||||
cell = grid.at(x, GRID_HEIGHT - 1)
|
||||
cell.walkable = False
|
||||
cell.transparent = False
|
||||
cell.sprite_index = 35 # '#' character
|
||||
cell.color = mcrfpy.Color(100, 100, 100)
|
||||
|
||||
for y in range(GRID_HEIGHT):
|
||||
# Left wall
|
||||
cell = grid.at(0, y)
|
||||
cell.walkable = False
|
||||
cell.transparent = False
|
||||
cell.sprite_index = 35 # '#' character
|
||||
cell.color = mcrfpy.Color(100, 100, 100)
|
||||
|
||||
# Right wall
|
||||
cell = grid.at(GRID_WIDTH - 1, y)
|
||||
cell.walkable = False
|
||||
cell.transparent = False
|
||||
cell.sprite_index = 35 # '#' character
|
||||
cell.color = mcrfpy.Color(100, 100, 100)
|
||||
|
||||
# Create the room
|
||||
create_room()
|
||||
```
|
||||
|
||||
## Creating the Player
|
||||
|
||||
Now let's add our player character:
|
||||
|
||||
```python
|
||||
# Create the player entity
|
||||
player = mcrfpy.Entity(x=GRID_WIDTH // 2, y=GRID_HEIGHT // 2, grid=grid)
|
||||
player.sprite_index = 64 # '@' character
|
||||
player.color = mcrfpy.Color(255, 255, 255) # White
|
||||
|
||||
# The entity is automatically added to the grid when we pass grid= parameter
|
||||
# This is equivalent to: grid.entities.append(player)
|
||||
```
|
||||
|
||||
## Handling Input
|
||||
|
||||
McRogueFace uses a callback system for input. For a turn-based roguelike, we only care about key presses, not releases:
|
||||
|
||||
```python
|
||||
def handle_input(key, state):
|
||||
"""Handle keyboard input for player movement"""
|
||||
# Only process key presses, not releases
|
||||
if state != "start":
|
||||
return
|
||||
|
||||
# Movement deltas
|
||||
dx, dy = 0, 0
|
||||
|
||||
# Arrow keys
|
||||
if key == "Up":
|
||||
dy = -1
|
||||
elif key == "Down":
|
||||
dy = 1
|
||||
elif key == "Left":
|
||||
dx = -1
|
||||
elif key == "Right":
|
||||
dx = 1
|
||||
|
||||
# Numpad movement (for true roguelike feel!)
|
||||
elif key == "Num7": # Northwest
|
||||
dx, dy = -1, -1
|
||||
elif key == "Num8": # North
|
||||
dy = -1
|
||||
elif key == "Num9": # Northeast
|
||||
dx, dy = 1, -1
|
||||
elif key == "Num4": # West
|
||||
dx = -1
|
||||
elif key == "Num6": # East
|
||||
dx = 1
|
||||
elif key == "Num1": # Southwest
|
||||
dx, dy = -1, 1
|
||||
elif key == "Num2": # South
|
||||
dy = 1
|
||||
elif key == "Num3": # Southeast
|
||||
dx, dy = 1, 1
|
||||
|
||||
# Escape to quit
|
||||
elif key == "Escape":
|
||||
mcrfpy.setScene(None)
|
||||
return
|
||||
|
||||
# If there's movement, try to move the player
|
||||
if dx != 0 or dy != 0:
|
||||
move_player(dx, dy)
|
||||
|
||||
# Register the input handler
|
||||
mcrfpy.keypressScene(handle_input)
|
||||
```
|
||||
|
||||
## Implementing Movement with Collision Detection
|
||||
|
||||
Now let's implement the movement function with proper collision detection:
|
||||
|
||||
```python
|
||||
def move_player(dx, dy):
|
||||
"""Move the player if the destination is walkable"""
|
||||
# Calculate new position
|
||||
new_x = player.x + dx
|
||||
new_y = player.y + dy
|
||||
|
||||
# Check bounds
|
||||
if new_x < 0 or new_x >= GRID_WIDTH or new_y < 0 or new_y >= GRID_HEIGHT:
|
||||
return
|
||||
|
||||
# Check if the destination is walkable
|
||||
destination = grid.at(new_x, new_y)
|
||||
if destination.walkable:
|
||||
# Move the player
|
||||
player.x = new_x
|
||||
player.y = new_y
|
||||
# The entity will automatically animate to the new position!
|
||||
```
|
||||
|
||||
## Adding Visual Polish
|
||||
|
||||
Let's add some UI elements to make our game look more polished:
|
||||
|
||||
```python
|
||||
# Add a title
|
||||
title = mcrfpy.Caption("McRogueFace Roguelike", 512, 30)
|
||||
title.font_size = 24
|
||||
title.fill_color = mcrfpy.Color(255, 255, 100) # Yellow
|
||||
ui.append(title)
|
||||
|
||||
# Add instructions
|
||||
instructions = mcrfpy.Caption("Arrow Keys or Numpad to move, ESC to quit", 512, 60)
|
||||
instructions.font_size = 16
|
||||
instructions.fill_color = mcrfpy.Color(200, 200, 200) # Light gray
|
||||
ui.append(instructions)
|
||||
|
||||
# Add a status line at the bottom
|
||||
status = mcrfpy.Caption("@ You", 100, 600)
|
||||
status.font_size = 18
|
||||
status.fill_color = mcrfpy.Color(255, 255, 255)
|
||||
ui.append(status)
|
||||
```
|
||||
|
||||

## Understanding What We've Built
|
||||
|
||||
Let's review the key concepts we've implemented:
|
||||
|
||||
1. **Grid-Entity Architecture**: The Grid represents our static world (floors and walls), while the Entity (player) moves on top of it.
|
||||
|
||||
2. **Collision Detection**: By checking the `walkable` property of grid cells, we prevent the player from walking through walls.
|
||||
|
||||
3. **Turn-Based Input**: By only responding to key presses (not releases), we've created true turn-based movement.
|
||||
|
||||
4. **Visual Feedback**: The Entity system automatically animates movement between tiles, giving smooth visual feedback.
|
||||
|
||||
## Exercises
|
||||
|
||||
Try these modifications to deepen your understanding:
|
||||
|
||||
1. **Add More Rooms**: Create multiple rooms connected by corridors
|
||||
2. **Different Tile Types**: Add doors (walkable but different appearance)
|
||||
3. **Sprint Movement**: Hold Shift to move multiple tiles at once
|
||||
4. **Mouse Support**: Click a tile to pathfind to it (we'll cover pathfinding properly later)
|
||||
|
||||
## ASCII Sprite Reference
|
||||
|
||||
Here are some useful ASCII character indices for the default tileset:
|
||||
- @ (player): 64
|
||||
- # (wall): 35
|
||||
- . (floor): 46
|
||||
- + (door): 43
|
||||
- ~ (water): 126
|
||||
- % (item): 37
|
||||
- ! (potion): 33
|
||||
|
||||
## What's Next?
|
||||
|
||||
In Part 2, we'll expand our world with:
|
||||
- A proper Entity system for managing multiple objects
|
||||
- NPCs that can also move around
|
||||
- A more interesting map layout
|
||||
- The beginning of our game architecture
|
||||
|
||||
The foundation is set - you have a player character that can move around a world with collision detection. This is the core of any roguelike game!

# Part 2 - The Generic Entity, the Render Functions, and the Map
|
||||
|
||||
In Part 1, we created a player character that could move around a simple room. Now it's time to build a proper architecture for our roguelike. We'll create a flexible entity system, a proper map structure, and organize our code for future expansion.
|
||||
|
||||
## Understanding Game Architecture
|
||||
|
||||
Before diving into code, let's understand the architecture we're building:
|
||||
|
||||
1. **Entities**: Anything that can exist in the game world (player, monsters, items)
|
||||
2. **Game Map**: The dungeon structure with tiles that can be walls or floors
|
||||
3. **Game Engine**: Coordinates everything - entities, map, input, and rendering
|
||||
|
||||
In McRogueFace, we'll adapt these concepts to work with the engine's scene-based architecture.
|
||||
|
||||
## Creating a Flexible Entity System
|
||||
|
||||
While McRogueFace provides a built-in `Entity` class, we'll create a wrapper to add game-specific functionality:
|
||||
|
||||
```python
|
||||
class GameObject:
|
||||
"""Base class for all game objects (player, monsters, items)"""
|
||||
|
||||
def __init__(self, x, y, sprite_index, color, name, blocks=False):
|
||||
self.x = x
|
||||
self.y = y
|
||||
self.sprite_index = sprite_index
|
||||
self.color = color
|
||||
self.name = name
|
||||
self.blocks = blocks # Does this entity block movement?
|
||||
self._entity = None # The McRogueFace entity
|
||||
self.grid = None # Reference to the grid
|
||||
|
||||
def attach_to_grid(self, grid):
|
||||
"""Attach this game object to a McRogueFace grid"""
|
||||
self.grid = grid
|
||||
self._entity = mcrfpy.Entity(x=self.x, y=self.y, grid=grid)
|
||||
self._entity.sprite_index = self.sprite_index
|
||||
self._entity.color = self.color
|
||||
|
||||
def move(self, dx, dy):
|
||||
"""Move by the given amount if possible"""
|
||||
if not self.grid:
|
||||
return
|
||||
|
||||
new_x = self.x + dx
|
||||
new_y = self.y + dy
|
||||
|
||||
# Update our position
|
||||
self.x = new_x
|
||||
self.y = new_y
|
||||
|
||||
# Update the visual entity
|
||||
if self._entity:
|
||||
self._entity.x = new_x
|
||||
self._entity.y = new_y
|
||||
|
||||
def destroy(self):
|
||||
"""Remove this entity from the game"""
|
||||
if self._entity and self.grid:
|
||||
# Find and remove from grid's entity list
|
||||
for i, entity in enumerate(self.grid.entities):
|
||||
if entity == self._entity:
|
||||
del self.grid.entities[i]
|
||||
break
|
||||
self._entity = None
|
||||
```
|
||||
|
||||
## Building the Game Map
|
||||
|
||||
Let's create a proper map class that manages our dungeon:
|
||||
|
||||
```python
|
||||
class GameMap:
|
||||
"""Manages the game world"""
|
||||
|
||||
def __init__(self, width, height):
|
||||
self.width = width
|
||||
self.height = height
|
||||
self.grid = None
|
||||
self.entities = [] # List of GameObjects
|
||||
|
||||
def create_grid(self, tileset):
|
||||
"""Create the McRogueFace grid"""
|
||||
self.grid = mcrfpy.Grid(grid_x=self.width, grid_y=self.height, texture=tileset)
|
||||
self.grid.position = (100, 100)
|
||||
self.grid.size = (800, 480)
|
||||
|
||||
# Initialize all tiles as walls
|
||||
self.fill_with_walls()
|
||||
|
||||
return self.grid
|
||||
|
||||
def fill_with_walls(self):
|
||||
"""Fill the entire map with wall tiles"""
|
||||
for y in range(self.height):
|
||||
for x in range(self.width):
|
||||
self.set_tile(x, y, walkable=False, transparent=False,
|
||||
sprite_index=35, color=(100, 100, 100))
|
||||
|
||||
def set_tile(self, x, y, walkable, transparent, sprite_index, color):
|
||||
"""Set properties for a specific tile"""
|
||||
if 0 <= x < self.width and 0 <= y < self.height:
|
||||
cell = self.grid.at(x, y)
|
||||
cell.walkable = walkable
|
||||
cell.transparent = transparent
|
||||
cell.sprite_index = sprite_index
|
||||
cell.color = mcrfpy.Color(*color)
|
||||
|
||||
def create_room(self, x1, y1, x2, y2):
|
||||
"""Carve out a room in the map"""
|
||||
# Make sure coordinates are in the right order
|
||||
x1, x2 = min(x1, x2), max(x1, x2)
|
||||
y1, y2 = min(y1, y2), max(y1, y2)
|
||||
|
||||
# Carve out floor tiles
|
||||
for y in range(y1, y2 + 1):
|
||||
for x in range(x1, x2 + 1):
|
||||
self.set_tile(x, y, walkable=True, transparent=True,
|
||||
sprite_index=46, color=(50, 50, 50))
|
||||
|
||||
def create_tunnel_h(self, x1, x2, y):
|
||||
"""Create a horizontal tunnel"""
|
||||
for x in range(min(x1, x2), max(x1, x2) + 1):
|
||||
self.set_tile(x, y, walkable=True, transparent=True,
|
||||
sprite_index=46, color=(50, 50, 50))
|
||||
|
||||
def create_tunnel_v(self, y1, y2, x):
|
||||
"""Create a vertical tunnel"""
|
||||
for y in range(min(y1, y2), max(y1, y2) + 1):
|
||||
self.set_tile(x, y, walkable=True, transparent=True,
|
||||
sprite_index=46, color=(50, 50, 50))
|
||||
|
||||
def is_blocked(self, x, y):
|
||||
"""Check if a tile blocks movement"""
|
||||
# Check map boundaries
|
||||
if x < 0 or x >= self.width or y < 0 or y >= self.height:
|
||||
return True
|
||||
|
||||

|
||||
if not self.grid.at(x, y).walkable:
|
||||
return True
|
||||
|
||||
# Check if any blocking entity is at this position
|
||||
for entity in self.entities:
|
||||
if entity.blocks and entity.x == x and entity.y == y:
|
||||
return True
|

|
||||
return False
|

|

def add_entity(self, entity):

return None

|

|

## Creating the Game Engine
|
||||
|
||||

|

```python

```
|
||||
|
||||
## Understanding the Architecture
|
||||
|
||||
### GameObject Class
|
||||
Our `GameObject` class wraps McRogueFace's `Entity` and adds:
|
||||
- Game logic properties (name, blocking)
|
||||
- Position tracking independent of the visual entity
|
||||
- Easy attachment/detachment from grids
|
||||
|
||||
### GameMap Class
|
||||
The `GameMap` manages:
|
||||
- The McRogueFace `Grid` for visual representation
|
||||
- A list of all entities in the map
|
||||
- Collision detection including entity blocking
|
||||
- Map generation utilities (rooms, tunnels)
|
||||
|
||||
### Engine Class
|
||||
The `Engine` coordinates everything:
|
||||
- Scene and UI setup
|
||||
- Game state management
|
||||
- Input handling
|
||||
- Entity-map interactions
|
||||
|
||||
## Key Improvements from Part 1
|
||||
|
||||
1. **Proper Entity Management**: Multiple entities can exist and interact
|
||||
2. **Blocking Entities**: Some entities block movement, others don't
|
||||
3. **Map Generation**: Tools for creating rooms and tunnels
|
||||
4. **Collision System**: Checks both tiles and entities
|
||||
5. **Organized Code**: Clear separation of concerns
|
||||
|
||||
## Exercises
|
||||
|
||||
1. **Add More Entity Types**: Create different sprites for monsters, items, and NPCs
|
||||
2. **Entity Interactions**: Make items disappear when walked over
|
||||
3. **Random Map Generation**: Place rooms and tunnels randomly
|
||||
4. **Entity Properties**: Add health, damage, or other attributes to GameObjects
|
||||
|
||||
## What's Next?
|
||||
|
||||
In Part 3, we'll implement proper dungeon generation with:
|
||||
- Procedurally generated rooms
|
||||
- Smart tunnel routing
|
||||
- Entity spawning
|
||||
- The beginning of a real roguelike dungeon!
|
||||
|
||||
We now have a solid foundation with proper entity management and map structure. This architecture will serve us well as we add more complex features to our roguelike!

# Part 3 - Generating a Dungeon
|
||||
|
||||
In Parts 1 and 2, we created a player that could move around and interact with a hand-crafted dungeon. Now it's time to generate dungeons procedurally - a core feature of any roguelike game!
|
||||
|
||||
## The Plan
|
||||
|
||||
We'll create a dungeon generator that:
|
||||
1. Places rectangular rooms randomly
|
||||
2. Ensures rooms don't overlap
|
||||
3. Connects rooms with tunnels
|
||||
4. Places the player in the first room
|
||||
|
||||
This is a classic approach used by many roguelikes, and it creates interesting, playable dungeons.
|
||||
|
||||
## Creating a Room Class
|
||||
|
||||
First, let's create a class to represent rectangular rooms:
|
||||
|
||||
```python
|
||||
class RectangularRoom:
|
||||
"""A rectangular room with its position and size"""
|
||||
|
||||
def __init__(self, x, y, width, height):
|
||||
self.x1 = x
|
||||
self.y1 = y
|
||||
self.x2 = x + width
|
||||
self.y2 = y + height
|
||||
|
||||
@property
|
||||
def center(self):
|
||||
"""Return the center coordinates of the room"""
|
||||
center_x = (self.x1 + self.x2) // 2
|
||||
center_y = (self.y1 + self.y2) // 2
|
||||
return center_x, center_y
|
||||
|
||||
@property
|
||||
def inner(self):
|
||||
"""Return the inner area of the room as a tuple of slices
|
||||
|
||||
This property returns the area inside the walls.
|
||||
We'll add 1 to min coordinates and subtract 1 from max coordinates.
|
||||
"""
|
||||
return self.x1 + 1, self.y1 + 1, self.x2 - 1, self.y2 - 1
|
||||
|
||||
def intersects(self, other):
|
||||
"""Return True if this room overlaps with another RectangularRoom"""
|
||||
return (
|
||||
self.x1 <= other.x2
|
||||
and self.x2 >= other.x1
|
||||
and self.y1 <= other.y2
|
||||
and self.y2 >= other.y1
|
||||
)
|
||||
```
|
||||
|
||||
## Implementing Tunnel Generation
|
||||
|
||||
Since McRogueFace doesn't include line-drawing algorithms, let's implement simple L-shaped tunnels:
|
||||
|
||||
```python
|
||||
def tunnel_between(start, end):
|
||||
"""Return an L-shaped tunnel between two points"""
|
||||
x1, y1 = start
|
||||
x2, y2 = end
|
||||
|
||||
# Randomly decide whether to go horizontal first or vertical first
|
||||
if random.random() < 0.5:
|
||||
# Horizontal, then vertical
|
||||
corner_x = x2
|
||||
corner_y = y1
|
||||
else:
|
||||
# Vertical, then horizontal
|
||||
corner_x = x1
|
||||
corner_y = y2
|
||||
|
||||
# Generate the coordinates
|
||||
# First line: from start to corner
|
||||
for x in range(min(x1, corner_x), max(x1, corner_x) + 1):
|
||||
yield x, y1
|
||||
for y in range(min(y1, corner_y), max(y1, corner_y) + 1):
|
||||
yield corner_x, y
|
||||
|
||||
# Second line: from corner to end
|
||||
for x in range(min(corner_x, x2), max(corner_x, x2) + 1):
|
||||
yield x, corner_y
|
||||
for y in range(min(corner_y, y2), max(corner_y, y2) + 1):
|
||||
yield x2, y
|
||||
```
|
||||
|
||||
## The Dungeon Generator
|
||||
|
||||
Now let's update our GameMap class to generate dungeons:
|
||||
|
||||
```python
|
||||
import random
|
||||
|
||||
class GameMap:
|
||||
"""Manages the game world"""
|
||||
|
||||

|
||||
self.width = width
|
||||
self.height = height
|
||||
self.grid = None
|
||||
self.entities = []
|
||||
self.rooms = [] # Keep track of rooms for game logic
|
||||
|
||||
def generate_dungeon(
|

max_rooms,

|

):
|

"""Generate a new dungeon map"""

self.fill_with_walls()
|

|

for r in range(max_rooms):
|

# Random width and height
|
||||
room_width = random.randint(room_min_size, room_max_size)
|
||||
room_height = random.randint(room_min_size, room_max_size)
|
||||
|
||||
# Random position without going out of bounds
|
||||
x = random.randint(0, self.width - room_width - 1)
|
||||
y = random.randint(0, self.height - room_height - 1)
|
||||
|
||||
# Create the room
|
||||
new_room = RectangularRoom(x, y, room_width, room_height)
|
||||
|
||||
# Check if it intersects with any existing room
|
||||
if any(new_room.intersects(other_room) for other_room in self.rooms):
|
||||
continue # This room intersects, so go to the next attempt
|
||||
|
||||
# If we get here, it's a valid room
|
||||

|
||||

|

|
||||
else:
|
||||

|
||||
# Tunnel between this room and the previous one
|
||||
self.carve_tunnel(self.rooms[-1].center, new_room.center)
|
||||
|
||||
# Finally, append the new room to the list
|
||||
self.rooms.append(new_room)
|
||||
|
||||
def carve_room(self, room):
|
||||
"""Carve out a room"""
|
||||
inner_x1, inner_y1, inner_x2, inner_y2 = room.inner

|

for y in range(inner_y1, inner_y2):

|
||||
|
||||
## Understanding the Algorithm
|
||||
|
||||
Our dungeon generation algorithm is simple but effective:
|
||||
|
||||
1. **Start with solid walls** - The entire map begins filled with wall tiles
|
||||
2. **Try to place rooms** - Generate random rooms and check for overlaps
|
||||
3. **Connect with tunnels** - Each new room connects to the previous one
|
||||
4. **Place entities** - The player starts in the first room, monsters in others
|
||||
|
||||
### Room Placement
|
||||
|
||||
The algorithm attempts to place `max_rooms` rooms, but may place fewer if many attempts result in overlapping rooms. This is called "rejection sampling" - we generate random rooms and reject ones that don't fit.
|
||||
|
||||
### Tunnel Design
|
||||
|
||||
Our L-shaped tunnels are simple but effective. They either go:
|
||||
- Horizontal first, then vertical
|
||||
- Vertical first, then horizontal
|
||||
|
||||
This creates variety while ensuring all rooms are connected.
|
||||
|
||||
## Experimenting with Parameters
|
||||
|
||||
Try adjusting these parameters to create different dungeon styles:
|
||||
|
||||
```python
|
||||
# Sparse dungeon with large rooms
|
||||
self.game_map.generate_dungeon(
|
||||
max_rooms=10,
|
||||
room_min_size=10,
|
||||
room_max_size=15,
|
||||
player=self.player
|
||||
)
|
||||
|
||||
# Dense dungeon with small rooms
|
||||
self.game_map.generate_dungeon(
|
||||
max_rooms=50,
|
||||
room_min_size=4,
|
||||
room_max_size=6,
|
||||
player=self.player
|
||||
)
|
||||
```
|
||||
|
||||
## Visual Enhancements
|
||||
|
||||
Notice how we gave tunnels a slightly different color:
|
||||
- Rooms: `color=(50, 50, 50)` - Medium gray
|
||||
- Tunnels: `color=(30, 30, 40)` - Darker with blue tint
|
||||
|
||||
This subtle difference helps players understand the dungeon layout.
|
||||
|
||||
## Exercises
|
||||
|
||||
1. **Different Room Shapes**: Create circular or cross-shaped rooms
|
||||
2. **Better Tunnel Routing**: Implement A* pathfinding for more natural tunnels
|
||||
3. **Room Types**: Create special rooms (treasure rooms, trap rooms)
|
||||
4. **Dungeon Themes**: Use different tile sets and colors for different dungeon levels
|
||||
|
||||
## What's Next?
|
||||
|
||||
In Part 4, we'll implement Field of View (FOV) so the player can only see parts of the dungeon they've explored. This will add mystery and atmosphere to our procedurally generated dungeons!
|
||||
|
||||
Our dungeon generator is now creating unique, playable levels every time. The foundation of a true roguelike is taking shape!

# Part 4 - Field of View
|
||||
|
||||
One of the defining features of roguelikes is exploration and discovery. In Part 3, we could see the entire dungeon at once. Now we'll implement Field of View (FOV) so players can only see what their character can actually see, adding mystery and tactical depth to our game.
|
||||
|
||||
## Understanding Field of View
|
||||
|
||||
Field of View creates three distinct visibility states for each tile:
|
||||
|
||||
1. **Visible**: Currently in the player's line of sight
|
||||
2. **Explored**: Previously seen but not currently visible
|
||||
3. **Unexplored**: Never seen (completely hidden)
|
||||
|
||||
This creates the classic "fog of war" effect where you remember the layout of areas you've explored, but can't see current enemy positions unless they're in your view.
|
||||
|
||||
## McRogueFace's FOV System
|
||||
|
||||
Good news! McRogueFace includes built-in FOV support through its C++ engine. We just need to enable and configure it. The engine uses an efficient shadowcasting algorithm that provides smooth, realistic line-of-sight calculations.
|
||||
|
||||
Let's update our code to use FOV:
|
||||
|
||||
```python
|
||||
class GameObject:
|
||||
"""Base class for all game objects"""
|
||||
def __init__(self, x, y, sprite_index, color, name, blocks=False):
|
||||
self.x = x
|
||||
self.y = y
|
||||
self.sprite_index = sprite_index
|
||||
self.color = color
|
||||
self.name = name
|
||||
self.blocks = blocks
|
||||
self._entity = None
|
||||
self.grid = None
|
||||
|
||||
def attach_to_grid(self, grid):
|
||||
"""Attach this game object to a McRogueFace grid"""
|
||||
self.grid = grid
|
||||
self._entity = mcrfpy.Entity(x=self.x, y=self.y, grid=grid)
|
||||
self._entity.sprite_index = self.sprite_index
|
||||
self._entity.color = mcrfpy.Color(*self.color)
|
||||
|
||||
def move(self, dx, dy):
|
||||
"""Move by the given amount"""
|
||||
if not self.grid:
|
||||
return
|
||||
self.x += dx
|
||||
self.y += dy
|
||||
if self._entity:
|
||||
self._entity.x = self.x
|
||||
self._entity.y = self.y
|
||||
# Update FOV when player moves
|
||||
if self.name == "Player":
|
||||
self.update_fov()
|
||||
|
||||
def update_fov(self):
|
||||
"""Update field of view from this entity's position"""
|
||||
if self._entity and self.grid:
|
||||
self._entity.update_fov(radius=8)
|
||||
```
|
||||
|
||||
## Configuring Visibility Rendering
|
||||
|
||||
McRogueFace automatically handles the rendering of visible/explored/unexplored tiles. We need to set up our grid to use perspective-based rendering:
|
||||
|
||||
```python
|
||||
class GameMap:
|
||||
"""Manages the game world"""
|
||||

## Visual Appearance Configuration
|
||||
|

Let's define how our tiles look in different visibility states:
|
||||
|
||||
```python
|
||||
# Color configurations for visibility states
|
||||
COLORS_VISIBLE = {
|
||||
'wall': (100, 100, 100), # Light gray
|
||||
'floor': (50, 50, 50), # Dark gray
|
||||
'tunnel': (30, 30, 40), # Dark blue-gray
|
||||
}
|
||||
|
||||
COLORS_EXPLORED = {
|
||||
'wall': (50, 50, 70), # Darker, bluish
|
||||
'floor': (20, 20, 30), # Very dark
|
||||
'tunnel': (15, 15, 25), # Almost black
|
||||
}
|
||||
|
||||
# Update the tile-setting methods to store the tile type
|
||||
def set_tile(self, x, y, walkable, transparent, sprite_index, tile_type):
|
||||
"""Set properties for a specific tile"""
|
||||
if 0 <= x < self.width and 0 <= y < self.height:
|
||||
cell = self.grid.at(x, y)
|
||||
cell.walkable = walkable
|
||||
cell.transparent = transparent
|
||||
cell.sprite_index = sprite_index
|
||||
# Store both visible and explored colors
|
||||
cell.color = mcrfpy.Color(*COLORS_VISIBLE[tile_type])

```
|
||||
|
||||
## How FOV Works
|
||||
|
||||
McRogueFace's built-in FOV system uses a shadowcasting algorithm that:
|
||||
|
||||
1. **Casts rays** from the player's position to tiles within the radius
|
||||
2. **Checks transparency** along each ray path
|
||||
3. **Marks tiles as visible** if the ray reaches them unobstructed
|
||||
4. **Remembers explored tiles** automatically
|
||||
|
||||
The engine handles all the complex calculations in C++ for optimal performance.
|
||||
|
||||
## Visibility States in Detail
|
||||
|
||||
### Visible Tiles
|
||||
- Currently in the player's line of sight
|
||||
- Rendered at full brightness
|
||||
- Show current entity positions
|
||||
|
||||
### Explored Tiles
|
||||
- Previously seen but not currently visible
|
||||
- Rendered darker/muted
|
||||
- Show remembered terrain but not entities
|
||||
|
||||
### Unexplored Tiles
|
||||
- Never been in the player's FOV
|
||||
- Rendered as black/invisible
|
||||
- Complete mystery to the player
|
||||
|
||||
## FOV Parameters
|
||||
|
||||
You can customize FOV behavior:
|
||||
|
||||
```python
|
||||
# Basic FOV update
|
||||
entity.update_fov(radius=8)
|
||||
|
||||
# The grid's perspective property controls rendering:
|
||||
grid.perspective = 0 # Use first entity's FOV (player)
|
||||
grid.perspective = 1 # Use second entity's FOV
|
||||
grid.perspective = -1 # Omniscient (no FOV, see everything)
|
||||
```
|
||||
|
||||
## Performance Considerations
|
||||
|
||||
McRogueFace's C++ FOV implementation is highly optimized:
|
||||
- Uses efficient shadowcasting algorithm
|
||||
- Only recalculates when needed
|
||||
- Handles large maps smoothly
|
||||
- Automatically culls entities outside FOV
|
||||
|
||||
## Visual Polish
|
||||
|
||||
The engine automatically handles visual transitions:
|
||||
- Smooth color changes between visibility states
|
||||
- Entities fade in/out of view
|
||||
- Explored areas remain visible but dimmed
|
||||
|
||||
## Exercises
|
||||
|
||||
1. **Variable Vision**: Give different entities different FOV radii
|
||||
2. **Light Sources**: Create torches that expand local FOV
|
||||
3. **Blind Spots**: Add pillars that create interesting shadows
|
||||
4. **X-Ray Vision**: Temporary power-up to see through walls
|
||||
|
||||
## What's Next?
|
||||
|
||||
In Part 5, we'll place enemies throughout the dungeon and implement basic interactions. With FOV in place, enemies will appear and disappear as you explore, creating tension and surprise!
|
||||
|
||||
Field of View transforms our dungeon from a tactical puzzle into a mysterious world to explore. The fog of war adds atmosphere and gameplay depth that's essential to the roguelike experience.

# Part 5 - Placing Enemies and Kicking Them (Harmlessly)
|
||||
|
||||
Now that we have Field of View working, it's time to populate our dungeon with enemies! In this part, we'll:
|
||||
- Place enemies randomly in rooms
|
||||
- Implement entity-to-entity collision detection
|
||||
- Create basic interactions (bumping into enemies)
|
||||
- Set the stage for combat in Part 6
|
||||
|
||||
## Enemy Spawning System
|
||||
|
||||
First, let's create a system to spawn enemies in our dungeon rooms. We'll avoid placing them in the first room (where the player starts) to give players a safe starting area.
|
||||
|
||||
```python
|
||||
def spawn_enemies_in_room(room, game_map, max_enemies=2):
|
||||
"""Spawn between 0 and max_enemies in a room"""
|
||||
import random
|
||||
|
||||
number_of_enemies = random.randint(0, max_enemies)
|
||||
|
||||
for i in range(number_of_enemies):
|
||||
# Try to find a valid position
|
||||
attempts = 10
|
||||
while attempts > 0:
|
||||
# Random position within room bounds
|
||||
x = random.randint(room.x1 + 1, room.x2 - 1)
|
||||
y = random.randint(room.y1 + 1, room.y2 - 1)
|
||||
|
||||
# Check if position is valid
|
||||
if not game_map.is_blocked(x, y):
|
||||
# 80% chance for orc, 20% for troll
|
||||
if random.random() < 0.8:
|
||||
enemy = GameObject(x, y, 111, (63, 127, 63), "Orc", blocks=True)
|
||||
else:
|
||||
enemy = GameObject(x, y, 84, (0, 127, 0), "Troll", blocks=True)
|
||||
|
||||
game_map.add_entity(enemy)
|
||||
break
|
||||
|
||||
attempts -= 1
|
||||
```
|
||||
|
||||
## Enhanced Collision Detection
|
||||
|
||||
We need to improve our collision detection to check for entities, not just walls:
|
||||
|
||||
```python
|
||||
class GameMap:
|
||||
"""Manages the game world"""
|
||||
|
||||
def get_blocking_entity_at(self, x, y):
|
||||
"""Return any blocking entity at the given position"""
|
||||
for entity in self.entities:
|
||||
if entity.blocks and entity.x == x and entity.y == y:
|
||||
return entity
|
||||
return None
|
||||
|
||||
def is_blocked(self, x, y):
|
||||
"""Check if a tile blocks movement"""
|
||||
# Check boundaries
|
||||
if x < 0 or x >= self.width or y < 0 or y >= self.height:
|
||||
return True
|
||||
|
||||
# Check walls
|
||||
if not self.grid.at(x, y).walkable:
|
||||
return True
|
||||
|
||||
# Check entities
|
||||
if self.get_blocking_entity_at(x, y):
|
||||
return True
|
||||
|
||||
return False
|
||||
```
|
||||
|
||||
## Action System Introduction
|
||||
|
||||
Let's create a simple action system to handle different types of interactions:
|
||||
|
||||
```python
|
||||
class Action:
|
||||
"""Base class for all actions"""
|
||||
pass
|
||||
|
||||
class MovementAction(Action):
|
||||
"""Action for moving an entity"""
|
||||
def __init__(self, dx, dy):
|
||||
self.dx = dx
|
||||
self.dy = dy
|
||||
|
||||
class BumpAction(Action):
|
||||
"""Action for bumping into something"""
|
||||
def __init__(self, dx, dy, target=None):
|
||||
self.dx = dx
|
||||
self.dy = dy
|
||||
self.target = target
|
||||
|
||||
class WaitAction(Action):
|
||||
"""Action for waiting/skipping turn"""
|
||||
pass
|
||||
```
|
||||
|
||||
## Handling Player Actions
|
||||
|
||||
Now let's update our movement handling to support bumping into enemies:
|
||||
|
||||
```python
|
||||
def handle_player_turn(self, action):
|
||||
"""Process the player's action"""
|
||||
if isinstance(action, MovementAction):
|
||||
dest_x = self.player.x + action.dx
|
||||
dest_y = self.player.y + action.dy
|
||||
|
||||
# Check what's at the destination
|
||||
target = self.game_map.get_blocking_entity_at(dest_x, dest_y)
|
||||
|
||||
if target:
|
||||
# We bumped into something!
|
||||
print(f"You kick the {target.name} in the shins, much to its annoyance!")
|
||||
elif not self.game_map.is_blocked(dest_x, dest_y):
|
||||
# Move the player
|
||||
self.player.move(action.dx, action.dy)
|
||||
# Update message
|
||||
self.status_text.text = "Exploring the dungeon..."
|
||||
else:
|
||||
# Bumped into a wall
|
||||
self.status_text.text = "Ouch! You bump into a wall."
|
||||
|
||||
elif isinstance(action, WaitAction):
|
||||
self.status_text.text = "You wait..."
|
||||
```
|
||||
|
||||
## Complete Updated Code

||||
|
||||

|
||||
|
||||
```python

## Understanding Entity Interactions
|
||||
|
||||
### Collision Detection
|
||||
Our system now checks three things when the player tries to move:
|
||||
1. **Map boundaries** - Can't move outside the map
|
||||
2. **Wall tiles** - Can't walk through walls
|
||||
3. **Blocking entities** - Can't walk through enemies
|
||||
|
||||
### The Action System
|
||||
We've introduced a simple action system that will grow in Part 6:
|
||||
- `Action` - Base class for all actions
|
||||
- `MovementAction` - Represents attempted movement
|
||||
- `WaitAction` - Skip a turn (important for turn-based games)
|
||||
|
||||
### Entity Spawning
|
||||
Enemies are placed randomly in rooms with these rules:
|
||||
- Never in the first room (player's starting room)
|
||||
- Random number between 0 and max per room
|
||||
- 80% orcs, 20% trolls
|
||||
- Must be placed on walkable, unoccupied tiles
|
||||
|
||||
## Visual Feedback
|
||||
|
||||
With FOV enabled, enemies will appear and disappear as you explore:
|
||||
- Enemies in sight are fully visible
|
||||
- Enemies in explored but dark areas are hidden
|
||||
- Creates tension and surprise encounters
|
||||
|
||||
## Exercises
|
||||
|
||||
1. **More Enemy Types**: Add different sprites and names (goblins, skeletons)
|
||||
2. **Enemy Density**: Adjust spawn rates based on dungeon depth
|
||||
3. **Special Rooms**: Create rooms with guaranteed enemies or treasures
|
||||
4. **Better Feedback**: Add sound effects or visual effects for bumping
|
||||
|
||||
## What's Next?
|
||||
|
||||
In Part 6, we'll transform those harmless kicks into a real combat system! We'll add:
|
||||
- Health points for all entities
|
||||
- Damage calculations
|
||||
- Death and corpses
|
||||
- Combat messages
|
||||
- The beginning of a real roguelike!
|
||||
|
||||
Right now our enemies are just obstacles. Soon they'll fight back!

# Part 6 - Doing (and Taking) Some Damage
|
||||
|
||||
It's time to turn our harmless kicks into real combat! In this part, we'll implement:
|
||||
- Health points for all entities
|
||||
- A damage calculation system
|
||||
- Death and corpse mechanics
|
||||
- Combat feedback messages
|
||||
- The foundation of tactical roguelike combat
|
||||
|
||||
## Adding Combat Stats
|
||||
|
||||
First, let's enhance our GameObject class with combat capabilities:
|
||||
|
||||
```python
|
||||
class GameObject:
|
||||
"""Base class for all game objects"""
|
||||
def __init__(self, x, y, sprite_index, color, name,
|
||||
blocks=False, hp=0, defense=0, power=0):
|
||||
self.x = x
|
||||
self.y = y
|
||||
self.sprite_index = sprite_index
|
||||
self.color = color
|
||||
self.name = name
|
||||
self.blocks = blocks
|
||||
self._entity = None
|
||||
self.grid = None
|
||||
|
||||
# Combat stats
|
||||
self.max_hp = hp
|
||||
self.hp = hp
|
||||
self.defense = defense
|
||||
self.power = power
|
||||
|
||||
@property
|
||||
def is_alive(self):
|
||||
"""Returns True if this entity can act"""
|
||||
return self.hp > 0
|
||||
|
||||
def take_damage(self, amount):
|
||||
"""Apply damage to this entity"""
|
||||
damage = amount - self.defense
|
||||
if damage > 0:
|
||||
self.hp -= damage
|
||||
|
||||
# Check for death
|
||||
if self.hp <= 0 and self.hp + damage > 0:
|
||||
self.die()
|
||||
|
||||
return damage
|
||||
|
||||
def die(self):
|
||||
"""Handle entity death"""
|
||||
if self.name == "Player":
|
||||
# Player death is special - we'll handle it differently
|
||||
self.sprite_index = 64 # Stay as @ but change color
|
||||
self.color = (127, 0, 0) # Dark red
|
||||
if self._entity:
|
||||
self._entity.color = mcrfpy.Color(127, 0, 0)
|
||||
print("You have died!")
|
||||
else:
|
||||
# Enemy death
|
||||
self.sprite_index = 37 # % character for corpse
|
||||
self.color = (127, 0, 0) # Dark red
|
||||
self.blocks = False # Corpses don't block
|
||||
self.name = f"remains of {self.name}"
|
||||
|
||||
if self._entity:
|
||||
self._entity.sprite_index = 37
|
||||
self._entity.color = mcrfpy.Color(127, 0, 0)
|
||||
```
|
||||
|
||||
## The Combat System
|
||||
|
||||
Now let's implement actual combat when entities bump into each other:
|
||||
|
||||
```python
|
||||
class MeleeAction(Action):
|
||||
"""Action for melee attacks"""
|
||||
def __init__(self, attacker, target):
|
||||
self.attacker = attacker
|
||||
self.target = target
|
||||
|
||||
def perform(self):
|
||||
"""Execute the attack"""
|
||||
if not self.target.is_alive:
|
||||
return # Can't attack the dead
|
||||
|
||||
damage = self.attacker.power - self.target.defense
|
||||
|
||||
if damage > 0:
|
||||
attack_desc = f"{self.attacker.name} attacks {self.target.name} for {damage} damage!"
|
||||
self.target.take_damage(damage)
|
||||
else:
|
||||
attack_desc = f"{self.attacker.name} attacks {self.target.name} but does no damage."
|
||||
|
||||
return attack_desc
|
||||
```
|
||||
|
||||
## Entity Factories
|
||||
|
||||
Let's create factory functions for consistent entity creation:
|
||||
|
||||
```python
|
||||
def create_player(x, y):
|
||||
"""Create the player entity"""
|
||||
return GameObject(
|
||||
x=x, y=y,
|
||||
sprite_index=64, # @
|
||||
color=(255, 255, 255),
|
||||
name="Player",
|
||||
blocks=True,
|
||||
hp=30,
|
||||
defense=2,
|
||||
power=5
|
||||
)
|
||||
|
||||
def create_orc(x, y):
|
||||
"""Create an orc enemy"""
|
||||
return GameObject(
|
||||
x=x, y=y,
|
||||
sprite_index=111, # o
|
||||
color=(63, 127, 63),
|
||||
name="Orc",
|
||||
blocks=True,
|
||||
hp=10,
|
||||
defense=0,
|
||||
power=3
|
||||
)
|
||||
|
||||
def create_troll(x, y):
|
||||
"""Create a troll enemy"""
|
||||
return GameObject(
|
||||
x=x, y=y,
|
||||
sprite_index=84, # T
|
||||
color=(0, 127, 0),
|
||||
name="Troll",
|
||||
blocks=True,
|
||||
hp=16,
|
||||
defense=1,
|
||||
power=4
|
||||
)
|
||||
```
|
||||
|
||||
## The Message Log
|
||||
|
||||
Combat needs feedback! Let's create a simple message log:
|
||||
|
||||
```python
|
||||
class MessageLog:
|
||||
"""Manages game messages"""
|
||||
def __init__(self, max_messages=5):
|
||||
self.messages = []
|
||||
self.max_messages = max_messages
|
||||
|
||||
def add_message(self, text, color=(255, 255, 255)):
|
||||
"""Add a message to the log"""
|
||||
self.messages.append((text, color))
|
||||
# Keep only recent messages
|
||||
if len(self.messages) > self.max_messages:
|
||||
self.messages.pop(0)
|
||||
|
||||
def render(self, ui, x, y, line_height=20):
|
||||
"""Render messages to the UI"""
|
||||
for i, (text, color) in enumerate(self.messages):
|
||||
caption = mcrfpy.Caption(text, x, y + i * line_height)
|
||||
caption.font_size = 14
|
||||
caption.fill_color = mcrfpy.Color(*color)
|
||||
ui.append(caption)
|
||||
```
|
||||
|
||||
## Complete Implementation
|
||||
|
||||
Here's the complete `game.py` with combat:
|
||||
|
||||
```python
|
||||

|

}

McRogueFace Tutorial - Part 2: Animated Movement
|
||||
|
||||
This tutorial builds on Part 1 by adding:
|
||||
- Animation system for smooth movement
|
||||
- Movement that takes 0.5 seconds per tile
|
||||
- Input blocking during movement animation

- Circular orbit calculations
|

- Grid-aligned geometric primitives
|
