Remove the is_hidden_in_tunnel() checks from Explosion.draw() and
Gas.draw() so explosions and gas clouds remain visible when their center
falls inside a tunnel cell. Logic already spawned them in tunnel cells,
but they were rendered invisible because the draw path returned early.
Previously Rat.draw() hid any rat whose center fell inside a tunnel.
The clipping helper only handled single-entrance cells and returned None
for internal passages/crossroads, causing rats to vanish entirely.
Now internal tunnel cells (those with 0 or 2+ open sides) draw the rat
normally so it remains visible while walking through the tunnel.
Single-entrance cells keep the partial clip effect.
Also fix the visible-ratio math for DOWN/RIGHT clipping: the old
formulas subtracted cell_size from a local coordinate, producing
zero or negative visibility.
- Move gas poisoning from Gas.move() to Gas.collisions() so all rats are
registered in the collision system before the poison query runs.
- Shrink gas and explosion bboxes so rats must be well inside the tile to
be poisoned/killed.
- Use AABB overlap instead of partial_move threshold for gas poisoning.
- Draw mobile units first, then top-layer effects (gas, mines, bombs,
explosions) so rats appear under the gas.
- Add draw_on_top hint to Unit base class and top-layer units.
- Move Timer explosion from move() to collisions() so all units are
registered in the collision system before the kill query runs.
- Explosion units now set a bbox and kill rats that touch them.
- Guard Rat.draw() so dead rats are not drawn.
- Remove units/__pycache__ files from tracking.
- Introduced `test_final_level_flow.py` to validate final level transitions and game end scenarios.
- Created `test_game_over_flow.py` to ensure game over conditions trigger correctly based on rat counts.
- Implemented `test_keybindings.py` to verify keybinding configurations and their context-specific actions.
- Developed `test_level_editor.py` to assess level editor functionalities and layout computations.
- Added `test_level_io.py` for testing level data serialization and deserialization.
- Established `test_loop_logic_parity.py` to ensure consistent game state across multiple simulation runs.
- Created `test_non_regression.py` to simulate game behavior and capture states for future verification.
- Implemented `test_verify.py` to compare current game states against a golden master for regression detection.
- Introduced a new JSON file containing non-regression test states with detailed unit information, including positions, ages, and movement directions across multiple frames.
- Added a shell script for Bluetooth diagnostics that checks system information, Bluetooth binaries, running processes, D-Bus status, Bluetooth controller details, and audio stack status, providing a comprehensive overview for troubleshooting.
- Added BMP_1_EXPLOSION_DOWN.png to original and preview directories.
- Added BMP_1_EXPLOSION_LEFT.png to original and preview directories.
- Added BMP_1_EXPLOSION_RIGHT.png to original and preview directories.
- Added BMP_1_EXPLOSION_UP.png to original and preview directories.
These assets are part of the explosion animation for the game, enhancing visual effects during gameplay.
- Added `image_clean.png` to the output directory for the clean image representation.
- Added `image_clean_preview.png` for the preview of the clean image.
- Introduced `image_svg_clean.png` for the SVG clean image representation.
Major improvements:
