commit 90c318104b
Author: John McCardle <mccardle.john@gmail.com>
Date:   Sat Jul 5 10:34:06 2025 -0400

    Fix Issue #63: Implement z-order rendering with dirty flag optimization

    - Add dirty flags to PyScene and UIFrame to track when sorting is needed
    - Implement lazy sorting - only sort when z_index changes or elements are added/removed
    - Make Frame children respect z_index (previously rendered in insertion order only)
    - Update UIDrawable::set_int to notify when z_index changes
    - Mark collections dirty on append, remove, setitem, and slice operations
    - Remove per-frame vector copy in PyScene::render for better performance

    Implement complete Python Sequence Protocol for collections (closes #69)

    Major implementation of the full sequence protocol for both UICollection
    and UIEntityCollection, making them behave like proper Python sequences.

    Core Features Implemented:
    - __setitem__ (collection[i] = value) with type validation
    - __delitem__ (del collection[i]) with proper cleanup
    - __contains__ (item in collection) by C++ pointer comparison
    - __add__ (collection + other) returns Python list
    - __iadd__ (collection += other) with full validation before modification
    - Negative indexing support throughout
    - Complete slice support (getting, setting, deletion)
    - Extended slices with step \!= 1
    - index() and count() methods
    - Type safety enforced for all operations

    UICollection specifics:
    - Accepts Frame, Caption, Sprite, and Grid objects only
    - Preserves z_index when replacing items
    - Auto-assigns z_index on append (existing behavior maintained)

    UIEntityCollection specifics:
    - Accepts Entity objects only
    - Manages grid references on add/remove/replace
    - Uses std::list iteration with std::advance()

    Also includes:
    - Default value support for constructors:
      - Caption accepts None for font (uses default_font)
      - Grid accepts None for texture (uses default_texture)
      - Sprite accepts None for texture (uses default_texture)
      - Entity accepts None for texture (uses default_texture)

    This completes Issue #69, removing it as an Alpha Blocker.

commit 70cf44f8f0
Author: John McCardle <mccardle.john@gmail.com>
Date:   Sat Jul 5 00:56:42 2025 -0400

    Implement comprehensive animation system (closes #59)

    - Add Animation class with 30+ easing functions (linear, ease in/out, quad, cubic, elastic, bounce, etc.)
    - Add property system to all UI classes for animation support:
      - UIFrame: position, size, colors (including individual r/g/b/a components)
      - UICaption: position, size, text, colors
      - UISprite: position, scale, sprite_number (with sequence support)
      - UIGrid: position, size, camera center, zoom
      - UIEntity: position, sprite properties
    - Create AnimationManager singleton for frame-based updates
    - Add Python bindings through PyAnimation wrapper
    - Support for delta animations (relative values)
    - Fix segfault when running scripts directly (mcrf_module initialization)
    - Fix headless/windowed mode behavior to respect --headless flag
    - Animations run purely in C++ without Python callbacks per frame

    All UI properties are now animatable with smooth interpolation and professional easing curves.

    Remove deprecated registerPyAction/registerInputAction system (closes #2, closes #3)

    This is our largest net-negative commit yet\! Removed the entire deprecated
    action registration system that provided unnecessary two-step indirection:
    keyboard → action string → Python callback

    Removed components:
    - McRFPy_API::_registerPyAction() and _registerInputAction() methods
    - McRFPy_API::callbacks map for storing Python callables
    - McRFPy_API::doAction() method for executing callbacks
    - ACTIONPY macro from Scene.h for detecting "_py" suffixed actions
    - Scene::registerActionInjected() and unregisterActionInjected() methods
    - tests/api_registerPyAction_issue2_test.py (tested deprecated functionality)

    The game now exclusively uses keypressScene() for keyboard input handling,
    which is simpler and more direct. Also commented out the unused _camFollow
    function that referenced non-existent do_camfollow variable.

    Remove deprecated player_input and turn-based functions for Issue #3

    Removed the commented-out player_input(), computerTurn(), and playerTurn()
    functions that were part of the old turn-based system. These are no longer
    needed as input is now handled through Scene callbacks.

    Partial fix for #3

Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 21:09:06 2025 -0400

    Implement sprite index validation for Issue #33

    Added validation to prevent setting sprite indices outside the valid
    range for a texture. The implementation:
    - Adds getSpriteCount() method to PyTexture to expose total sprites
    - Validates sprite_number setter to ensure index is within bounds
    - Provides clear error messages showing valid range
    - Works for both Sprite and Entity objects

    closes #33

commit 1e7f5e9e7e
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 21:05:47 2025 -0400

    Implement EntityCollection.extend() method for Issue #27

    Added extend() method to EntityCollection that accepts any iterable
    of Entity objects and adds them all to the collection. The method:
    - Accepts lists, tuples, generators, or any iterable
    - Validates all items are Entity objects
    - Sets the grid association for each added entity
    - Properly handles errors and empty iterables

    closes #27

Date:   Thu Jul 3 21:02:14 2025 -0400

    Implement Entity.index() method for Issue #73

    Added index() method to Entity class that returns the entity's
    position in its parent grid's entity collection. This enables
    proper entity removal patterns using entity.index().

Date:   Thu Jul 3 20:41:03 2025 -0400

    Add validation to keypressScene() for non-callable arguments

    Added PyCallable_Check validation to ensure keypressScene() only
    accepts callable objects. Now properly raises TypeError with a
    clear error message when passed non-callable arguments like
    strings, numbers, None, or dicts.

commit 4715356b5e
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 20:31:36 2025 -0400

    Fix Sprite texture setter 'error return without exception set'

    Implemented the missing UISprite::set_texture method to properly:
    - Validate the input is a Texture instance
    - Update the sprite's texture using setTexture()
    - Return appropriate error messages for invalid inputs

    The setter now works correctly and no longer returns -1 without
    setting an exception.

commit 6dd1cec600
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 20:27:32 2025 -0400

    Fix Entity property setters and PyVector implementation

    Fixed the 'new style getargs format' error in Entity property setters by:
    - Implementing PyObject_to_sfVector2f/2i using PyVector::from_arg
    - Adding proper error checking in Entity::set_position
    - Implementing PyVector get_member/set_member for x/y properties
    - Fixing PyVector::from_arg to handle non-tuple arguments correctly

    Now Entity.pos and Entity.sprite_number setters work correctly with
    proper type validation.

Date:   Thu Jul 3 19:48:33 2025 -0400

    Fix Issue #74: Add missing Grid.grid_y property

    Added individual grid_x and grid_y getter properties to the Grid class
    to complement the existing grid_size property. This allows direct access
    to grid dimensions and fixes error messages that referenced these
    properties before they existed.

    closes #74

commit 59e6f8d53d
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 19:42:32 2025 -0400

    Fix Issue #78: Middle mouse click no longer sends 'C' keyboard event

    The bug was caused by accessing event.key.code on a mouse event without
    checking the event type first. Since SFML uses a union for events, this
    read garbage data. The middle mouse button value (2) coincidentally matched
    the keyboard 'C' value (2), causing the spurious keyboard event.

    Fixed by adding event type check before accessing key-specific fields.
    Only keyboard events (KeyPressed/KeyReleased) now trigger key callbacks.

    Test added to verify middle clicks no longer generate keyboard events.

    Closes #78

commit 1c71d8d4f7
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 19:36:15 2025 -0400

    Fix Grid to support None/null texture and fix error message bug

    - Allow Grid to be created with None as texture parameter
    - Use default cell dimensions (16x16) when no texture provided
    - Skip sprite rendering when texture is null, but still render colors
    - Fix issue #77: Corrected copy/paste error in Grid.at() error messages
    - Grid now functional for color-only rendering and entity positioning

    Test created to verify Grid works without texture, showing colored cells.

    Closes #77

commit 18cfe93a44
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 19:25:49 2025 -0400

    Fix --exec interactive prompt bug and create comprehensive test suite

    Major fixes:
    - Fixed --exec entering Python REPL instead of game loop
    - Resolved screenshot transparency issue (requires timer callbacks)
    - Added debug output to trace Python initialization

    Test suite created:
    - 13 comprehensive tests covering all Python-exposed methods
    - Tests use timer callback pattern for proper game loop interaction
    - Discovered multiple critical bugs and missing features

    Critical bugs found:
    - Grid class segfaults on instantiation (blocks all Grid functionality)
    - Issue #78 confirmed: Middle mouse click sends 'C' keyboard event
    - Entity property setters have argument parsing errors
    - Sprite texture setter returns improper error
    - keypressScene() segfaults on non-callable arguments

    Documentation updates:
    - Updated CLAUDE.md with testing guidelines and TDD practices
    - Created test reports documenting all findings
    - Updated ROADMAP.md with test results and new priorities

    The Grid segfault is now the highest priority as it blocks all Grid-based functionality.

Date:   Thu Jul 3 15:55:24 2025 -0400

    Update ROADMAP.md to reflect Python interpreter and automation API progress

    - Mark #32 (Python interpreter behavior) as 90% complete
      - All major Python flags implemented: -h, -V, -c, -m, -i
      - Script execution with proper sys.argv handling works
      - Only stdin (-) support missing

    - Note that new automation API enables:
      - Automated UI testing capabilities
      - Demo recording and playback
      - Accessibility testing support

    - Flag issues #53 and #45 as potentially aided by automation API

    - Remove #72 (iterator improvements - closed)
    - Remove #51 (UIEntity derive from UIDrawable - closed)
    - Update issue counts: 64 open issues from original 78
    - Update dependencies and references to reflect closed issues
    - Clarify that core iterators are complete, only grid points remain

commit 68c1a016b0
Author: John McCardle <mccardle.john@gmail.com>
Date:   Thu Jul 3 14:27:01 2025 -0400

    Implement --exec flag and PyAutoGUI-compatible automation API

    - Add --exec flag to execute multiple scripts before main program
    - Scripts are executed in order and share Python interpreter state
    - Implement full PyAutoGUI-compatible automation API in McRFPy_Automation
    - Add screenshot, mouse control, keyboard input capabilities
    - Fix Python initialization issues when multiple scripts are loaded
    - Update CommandLineParser to handle --exec with proper sys.argv management
    - Add comprehensive examples and documentation

    This enables automation testing by allowing test scripts to run alongside
    games using the same Python environment. The automation API provides
    event injection into the SFML render loop for UI testing.

    Closes #32 partially (Python interpreter emulation)
