## 🚀 Alpha Streamline 2 - Comprehensive Phase Plan

### Phase 1: Foundation Stabilization (1-2 weeks)
**Goal**: Safe, predictable base for all future work
```
1. #7 - Audit and fix unsafe constructors (CRITICAL - do first!)
   - Find all manually implemented no-arg constructors
   - Verify map compatibility requirements
   - Make pointer-safe or remove
   
2. #71 - _Drawable base class implementation
   - Common properties: x, y, w, h, visible, opacity
   - Virtual methods: get_bounds(), render()
   - Proper Python inheritance setup
   
3. #87 - visible property
   - Add to base class
   - Update all render methods to check
   
4. #88 - opacity property (depends on #87)
   - 0.0-1.0 float range
   - Apply in render methods
   
5. #89 - get_bounds() method
   - Virtual method returning (x, y, w, h)
   - Override in each UI class
   
6. #98 - move()/resize() convenience methods
   - move(dx, dy) - relative movement
   - resize(w, h) - absolute sizing
```
*Rationale*: Can't build on unsafe foundations. Base class enables all UI improvements.

### Phase 2: Constructor & API Polish (1 week)
**Goal**: Pythonic, intuitive API
```
1. #101 - Standardize (0,0) defaults for all positions
2. #38 - Frame children parameter: Frame(children=[...])
3. #42 - Click handler in __init__: Button(click=callback)
4. #90 - Grid size tuple: Grid(grid_size=(10, 10))
5. #19 - Sprite texture swapping: sprite.texture = new_texture
6. #52 - Grid skip out-of-bounds entities (performance)
```
*Rationale*: Quick wins that make the API more pleasant before bigger changes.

### Phase 3: Entity Lifecycle Management (1 week)
**Goal**: Bulletproof entity/grid relationships
```
1. #30 - Entity.die() and grid association
   - Grid.entities.append(e) sets e.grid = self
   - Grid.entities.remove(e) sets e.grid = None
   - Entity.die() calls self.grid.remove(self)
   - Entity can only be in 0 or 1 grid
   
2. #93 - Vector arithmetic methods
   - add, subtract, multiply, divide
   - distance, normalize, dot product
   
3. #94 - Color helper methods
   - from_hex("#FF0000"), to_hex()
   - lerp(other_color, t) for interpolation
   
4. #103 - Timer objects
   timer = mcrfpy.Timer("my_timer", callback, 1000)
   timer.pause()
   timer.resume()
   timer.cancel()
```
*Rationale*: Games need reliable entity management. Timer objects enable entity AI.

### Phase 4: Visibility & Performance (1-2 weeks)
**Goal**: Only render/process what's needed
```
1. #10 - [UNSCHEDULED] Full visibility system with AABB
   - Postponed: UIDrawables can exist in multiple collections
   - Cannot reliably determine screen position due to multiple render contexts
   - Needs architectural solution for parent-child relationships
   
2. #52 - Grid culling (COMPLETED in Phase 2)
   
3. #39/40/41 - Name system for finding elements
   - name="button1" property on all UIDrawables
   - only_one=True for unique names
   - scene.find("button1") returns element
   - collection.find("enemy*") returns list
   
4. #104 - Basic profiling/metrics
   - Frame time tracking
   - Draw call counting
   - Python vs C++ time split
```
*Rationale*: Performance is feature. Finding elements by name is huge QoL.

### Phase 5: Window/Scene Architecture ✅ COMPLETE! (2025-07-06)
**Goal**: Modern, flexible architecture
```
1. ✅ #34 - Window object (singleton first)
   window = mcrfpy.Window.get()
   window.resolution = (1920, 1080)
   window.fullscreen = True
   window.vsync = True
   
2. ✅ #1 - Window resize events
   scene.on_resize(self, width, height) callback implemented
   
3. ✅ #61 - Scene object (OOP scenes)
   class MenuScene(mcrfpy.Scene):
       def on_keypress(self, key, state):
           # handle input
       def on_enter(self):
           # setup UI
       def on_exit(self):
           # cleanup
       def update(self, dt):
           # frame update
           
4. ✅ #14 - SFML exposure research
   - Completed comprehensive analysis
   - Recommendation: Direct integration as mcrfpy.sfml
   - SFML 3.0 migration deferred to late 2025
   
5. ✅ #105 - Scene transitions
   mcrfpy.setScene("menu", "fade", 1.0)
   # Supports: fade, slide_left, slide_right, slide_up, slide_down
```
*Result*: Entire window/scene system modernized with OOP design!

### Phase 6: Rendering Revolution (3-4 weeks) ✅ COMPLETE!
**Goal**: Professional rendering capabilities
```
1. ✅ #50 - Grid background colors [COMPLETED]
   grid.background_color = mcrfpy.Color(50, 50, 50)
   - Added background_color property with animation support
   - Default dark gray background (8, 8, 8, 255)
   
2. ✅ #6 - RenderTexture overhaul [COMPLETED]
   ✅ Base infrastructure in UIDrawable
   ✅ UIFrame clip_children property
   ✅ Dirty flag optimization system
   ✅ Nested clipping support
   ✅ UIGrid already has appropriate RenderTexture implementation
   ❌ UICaption/UISprite clipping not needed (no children)
   
3. ✅ #8 - Viewport-based rendering [COMPLETED]
   - Fixed game resolution (window.game_resolution)
   - Three scaling modes: "center", "stretch", "fit"
   - Window to game coordinate transformation
   - Mouse input properly scaled with windowToGameCoords()
   - Python API fully integrated
   - Tests: test_viewport_simple.py, test_viewport_visual.py, test_viewport_scaling.py
   
4. #106 - Shader support [DEFERRED TO POST-PHASE 7]
   sprite.shader = mcrfpy.Shader.load("glow.frag")
   frame.shader_params = {"intensity": 0.5}
   
5. #107 - Particle system [DEFERRED TO POST-PHASE 7]
   emitter = mcrfpy.ParticleEmitter()
   emitter.texture = spark_texture
   emitter.emission_rate = 100
   emitter.lifetime = (0.5, 2.0)
```

**Phase 6 Achievement Summary**:
- Grid backgrounds (#50) ✅ - Customizable background colors with animation
- RenderTexture overhaul (#6) ✅ - UIFrame clipping with opt-in architecture
- Viewport rendering (#8) ✅ - Three scaling modes with coordinate transformation
- UIGrid already had optimal RenderTexture implementation for its use case
- UICaption/UISprite clipping unnecessary (no children to clip)
- Performance optimized with dirty flag system
- Backward compatibility preserved throughout
- Effects/Shader/Particle systems deferred for focused delivery

*Rationale*: This unlocks professional visual effects but is complex.

### Phase 7: Documentation & Distribution (1-2 weeks)
**Goal**: Ready for the world
```
1. ✅ #85 - Replace all "docstring" placeholders [COMPLETED 2025-07-08]
2. ✅ #86 - Add parameter documentation [COMPLETED 2025-07-08]
3. ✅ #108 - Generate .pyi type stubs for IDE support [COMPLETED 2025-07-08]
4. ❌ #70 - PyPI wheel preparation [CANCELLED - Architectural mismatch]
5. API reference generator tool
```

## 📋 Critical Path & Parallel Tracks

### 🔴 **Critical Path** (Must do in order)
**Safe Constructors (#7)** → **Base Class (#71)** → **Visibility (#10)** → **Window (#34)** → **Scene (#61)**

### 🟡 **Parallel Tracks** (Can be done alongside critical path)

### 💎 **Quick Wins to Sprinkle Throughout**
1. Color helpers (#94) - 1 hour
2. Vector methods (#93) - 1 hour  
3. Grid backgrounds (#50) - 30 minutes
4. Default positions (#101) - 30 minutes

### 🎯 **Recommended Execution Order**

## 📋 Phase 6 Implementation Strategy

### RenderTexture Overhaul (#6) - Technical Approach

**Current State**:
- UIGrid already uses RenderTexture for entity rendering
- Scene transitions use RenderTextures for smooth animations
- Direct rendering to window for Frame, Caption, Sprite

**Implementation Plan**:
1. **Base Infrastructure**:
   - Add `sf::RenderTexture* target` to UIDrawable base
   - Modify `render()` to check if target exists
   - If target: render to texture, then draw texture to parent
   - If no target: render directly (backward compatible)

2. **Clipping Support**:
   - Frame enforces bounds on children via RenderTexture
   - Children outside bounds are automatically clipped
   - Nested frames create render texture hierarchy

3. **Performance Optimization**:
   - Lazy RenderTexture creation (only when needed)
   - Dirty flag system (only re-render when changed)
   - Texture pooling for commonly used sizes

4. **Integration Points**:
   - Scene transitions already working with RenderTextures
   - UIGrid can be reference implementation
   - Test with deeply nested UI structures

**Quick Wins Before Core Work**:
1. **Grid Background (#50)** - 30 min implementation
   - Add `background_color` and `background_texture` properties
   - Render before entities in UIGrid::render()
   - Good warm-up before tackling RenderTexture

2. **Research Tasks**:
   - Study UIGrid's current RenderTexture usage
   - Profile scene transition performance
   - Identify potential texture size limits

## 🔮 FUTURE VISION: Pure Python Extension Architecture

### Concept: McRogueFace as a Traditional Python Package
**Status**: Unscheduled - Long-term vision
**Complexity**: Major architectural overhaul

Instead of being a C++ application that embeds Python, McRogueFace could be redesigned as a pure Python extension module that can be installed via `pip install mcrogueface`.

### Technical Approach
1. **Separate Core Engine from Python Embedding**
   - Extract SFML rendering, audio, and input into C++ extension modules
   - Remove embedded CPython interpreter
   - Use Python's C API to expose functionality

2. **Module Structure**
   ```
   mcrfpy/
   ├── __init__.py          # Pure Python coordinator
   ├── _core.so             # C++ rendering/game loop extension
   ├── _sfml.so             # SFML bindings
   ├── _audio.so            # Audio system bindings
   └── engine.py            # Python game engine logic
   ```

3. **Inverted Control Flow**
   - Python drives the main loop instead of C++
   - C++ extensions handle performance-critical operations
   - Python manages game logic, scenes, and entity systems

### Benefits
- **Standard Python Packaging**: `pip install mcrogueface`
- **Virtual Environment Support**: Works with venv, conda, poetry
- **Better IDE Integration**: Standard Python development workflow  
- **Easier Testing**: Use pytest, standard Python testing tools
- **Cross-Python Compatibility**: Support multiple Python versions
- **Modular Architecture**: Users can import only what they need

### Challenges
- **Major Refactoring**: Complete restructure of codebase
- **Performance Considerations**: Python-driven main loop overhead
- **Build Complexity**: Multiple extension modules to compile
- **Platform Support**: Need wheels for many platform/Python combinations
- **API Stability**: Would need careful design to maintain compatibility

### Implementation Phases (If Pursued)
1. **Proof of Concept**: Simple SFML binding as Python extension
2. **Core Extraction**: Separate rendering from Python embedding
3. **Module Design**: Define clean API boundaries
4. **Incremental Migration**: Move systems one at a time
5. **Compatibility Layer**: Support existing games during transition

### Example Usage (Future Vision)
```python
import mcrfpy
from mcrfpy import Scene, Frame, Sprite, Grid

# Create game directly in Python
game = mcrfpy.Game(width=1024, height=768)

# Define scenes using Python classes
class MainMenu(Scene):
    def on_enter(self):
        self.ui.append(Frame(100, 100, 200, 50))
        self.ui.append(Sprite("logo.png", x=400, y=100))
    
    def on_keypress(self, key, pressed):
        if key == "ENTER" and pressed:
            self.game.set_scene("game")

# Run the game
game.add_scene("menu", MainMenu())
game.run()
```

This architecture would make McRogueFace a first-class Python citizen, following standard Python packaging conventions while maintaining high performance through C++ extensions.
