||
|
|
|
||
|
|
## Build Notes
|
||
|
|
|
||
|
|
### Phase 1: MVP Setup ✅

|
||
|
|
- [x] Game state management
|
||
|
|
|
||
|
|

|
||
|
|
- [x] **Core Module** (`src/core.lua`)
|
||
|
|

|
||
|
|

|
||
|
|

|
||
|
|
|
||
|
|

|
||
|
|

|
||
|
|

|
||
|
|
- Error handling for malformed JSON
|
||
|
|
|
||
|
|

|
||
|
|
- Procedural texture generation
|
||
|
|
- Cube mesh rendering
|
||
|
|
- AABB collision detection
|
||
|
|
- Raycasting for interaction
|
||
|
|
|
||
|
|
- [x] **Cat Module** (`src/cat/init.lua`)
|
||
|
|
- Cat class with state machine
|
||
|
|
- AI behavior system
|
||
|
|
- Personality compatibility logic
|
||
|
|
- Serialization for save/load
|
||
|
|
|
||
|
|
- [x] **House Module** (`src/house/init.lua`)
|
||
|
|
- Grid-based placement system
|
||
|
|
- Collision detection
|
||
|
|
- Furniture management
|
||
|
|
- Upgrade system
|
||
|
|
|
||
|
|
- [x] **UI Module** (`src/ui/init.lua`)
|
||
|
|
- HUD with happiness meter
|
||
|
|
- Inventory panel
|
||
|
|
- Cat log display
|
||
|
|
- Placement preview
|
||
|
|
|
||
|
|
- [x] **Audio Module** (`src/audio/init.lua`)
|
||
|
|
- Procedural purr sound
|
||
|
|
- Procedural meow sound
|
||
|
|
- Ambient room noise
|
||
|
|
- Click sound effects
|
||
|
|
|
||
|
|
### Phase 3: Polish ✅
|
||
|
|
- [x] Error handling throughout
|
||
|
|
- [x] Nil checks on all module access
|
||
|
|
- [x] Edge case handling (empty lists, zero distance)
|
||
|
|
- [x] Automatic cat departure logic
|
||
|
|
- [x] Camera-agnostic raycasting
|
||
|
|
- [x] Responsive UI scaling
|
||
|
|
|
||
|
|
### Phase 4: Neverending Loop ✅
|
||
|
|
- [x] Infinite cat spawning
|
||
|
|
- [x] Continuous happiness calculation
|
||
|
|
- [x] Auto-departure for unhappy cats
|
||
|
|
- [x] Persistent save system
|
||
|
|
|
||
|
|
## Known Limitations
|
||
|
|
|
||
|
|
1. **Audio**: Procedural sounds are basic waveforms, not realistic animal sounds
|
||
|
|
2. **Rendering**: Simple box models, no complex geometry
|
||
|
|
3. **VR**: Designed for VR but tested in 2D mode only
|
||
|
|
4. **Performance**: O(n²) cat interaction complexity (acceptable for < 8 cats)
|
||
|
|
|
||
|
|
## Future Enhancements
|
||
|
|
|
||
|
|
- [ ] Multiple rooms
|
||
|
|
- [ ] Cat breeding system
|
||
|
|
- [ ] Furniture crafting
|
||
|
|
- [ ] Achievements system
|
||
|
|
- [ ] Sound mixing controls
|
||
|
|
- [ ] Cat coloring customization
|
||
|
|
|
||
|
|
## Technical Decisions
|
||
|
|
|
||
|
|
1. **Module Loading**: Lazy loading to break circular dependencies
|
||
|
|
2. **JSON Format**: Custom implementation for LOVR compatibility
|
||
|
|
3. **Audio**: Procedural generation to avoid external assets
|
||
|
|
4. **Textures**: Runtime generation to avoid external assets
|
||
|
|
5. **Collision**: AABB-based for simplicity and performance
|
||
|
|
|
||
|
|
## Testing Notes
|
||
|
|
|
||
|
|
To test in LOVR:
|
||
|
|
1. Run `lovr ./` from project root
|
||
|
|
2. Press RThumb + S to save
|
||
|
|
3. Press RThumb + L to load
|
||
|
|
4. Press ESC to pause
|
||
|
|
5. Click inventory items to select furniture
|
||
|
|
6. Watch cats interact with furniture
|
