Four gameplay parameters are now driven by the selected difficulty,
following the existing 'hard = harder for the player' philosophy:
param easy normal hard
gas_spread_speed 40 50 90 (higher = slower gas)
weapon_refill_multiplier 1.3 1.0 0.6 (less ammo on hard)
max_babies 2 3 5 (more pups on hard)
mate_stop_male / female 120/240 100/200 60/120 (shorter stop on hard)
Implementation:
- engine/config.py: new keys on each DIFFICULTY_OPTIONS entry.
- rats.py: _apply_difficulty() loads them onto the game (with __init__
defaults for safety); normal keeps the previous hardcoded values.
- units/gas.py: Gas.speed reads game.gas_spread_speed (fallback 50).
- engine/unit_manager.py: refill_ammo() scales per-frame refill chances
by game.weapon_refill_multiplier (fallback 1.0).
- units/rat.py: Male.fuck() uses game.mate_stop_male/mate_stop_female
and random.randint(1, game.max_babies) (fallbacks to old values).
All reads use getattr with the previous constant as fallback, so older
configs / saved state keep working.
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.
- 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.
- 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.
- Introduced a hybrid collision detection approach that utilizes NumPy for vectorized operations, improving performance for games with many entities (200+).
- Added a spatial grid for efficient lookups and AABB (Axis-Aligned Bounding Box) collision detection.
- Implemented a new `CollisionSystem` class with methods for registering units, checking collisions, and managing spatial data.
- Created performance tests to benchmark the new collision system against the old O(n²) method, demonstrating significant speed improvements.
- Updated existing code to integrate the new collision detection system and ensure compatibility with game logic.
