+ +**Step 1: Plan the feature** +- Determine which module(s) need modification +- Define the feature's scope and requirements +- Consider test coverage needs + +**Step 2: Create test-first** +```lua +-- Write tests first +describe('New Feature', function() + it('should implement feature X') + it('should handle edge cases') +end) +``` + +**Step 3: Implement in module** +- Follow existing code patterns +- Use proper error handling +- Add comments only if requested + +**Step 4: Update documentation** +- Update this INSTRUCTIONS.md if needed +- Update README.md for user-facing changes + +**Step 5: Test and iterate** +```bash +# Run specific test +lua test/spec/newfeature_spec.lua + +# Run all tests +lua test/run_tests.lua +``` + +### Modifying Existing Modules + +**Guidelines:** + +1. **Read existing code first** + - Understand the current implementation + - Identify side effects + - Check test coverage + +2. **Update tests before code** + - Add tests for new behavior + - Update existing tests if behavior changes + +3. **Maintain consistency** + - Follow naming conventions + - Use existing patterns + - Preserve error handling + +4. **Test thoroughly** + ```bash + # Test the specific module + lua test/spec/core_spec.lua + + # Test integration + lua test/integration/game_flow_spec.lua + + # Test edge cases + lua test/e2e/edge_cases_spec.lua + ``` + +### Debugging Tips + +**1. Use print statements** +```lua +-- Debug module loading +print('Loading core module') + +-- Debug values +print('Current state:', json.encode(core.state)) +``` + +**2. LOVR console output** +```bash +# Enable verbose output +lovr . --verbose + +# Check for errors +lovr . 2>&1 | grep -i error +``` + +**3. Test helper utilities** +```lua +-- Use test helper for debugging +local utils = test_helper.utils +utils.assertDeepEqual(actual, expected, 'Debug message') +``` + +**4. Check module loading** +```lua +-- Verify module is loaded +assert(core, 'Core module not loaded') +assert(cat, 'Cat module not loaded') +``` + +**5. Validate data structures** +```lua +-- Check table structure +for k, v in pairs(core.state) do + print(string.format('%s: %s', k, type(v))) +end +``` + +### Code Style Guidelines + +**Naming Conventions:** +- **Modules**: lowercase with underscores (`core.lua`, `json.lua`) +- **Functions**: camelCase (`updateCats`, `createFurniture`) +- **Constants**: UPPER_SNAKE_CASE (`MAX_CATS`, `VOXEL_SIZE`) +- **Variables**: camelCase (`catCount`, `happinessScore`) +- **Classes**: PascalCase (`HouseFurniture`, `Cat`) + +**File Structure:** +```lua +-- 1.
