## Test Coverage
### Direction Calculation Tests
✅ **Cardinal Directions** (4 tests)
- Pure right (player directly east)
- Pure left (player directly west)
- Pure down (player directly south)
- Pure up (player directly north)
✅ **Diagonal Directions** (4 tests)
- Down-right (45° angle)
- Down-left (45° angle)
- Up-right (45° angle)
- Up-left (45° angle)
✅ **Threshold Tests** (8 tests)
- Mostly right (30° angle → cardinal)
- Mostly left (30° angle → cardinal)
- Mostly down (30° angle → cardinal)
- Mostly up (30° angle → cardinal)
- Barely diagonal right-down (60° → diagonal)
- Barely cardinal right (30° → cardinal)
- Barely diagonal down-right (30° → diagonal)
- Barely cardinal down (60° → cardinal)
✅ **Edge Cases** (5 tests)
- Zero distance (player on top of NPC)
- Small movements (1px)
- Large movements (1000px)
- Negative movements
- Boundary conditions
### Scenario Tests
✅ **12 NPCs in Test Scenario**:
1. `npc_center` - Default behavior, all 8 directions
2. `npc_north` - Cardinal north position
3. `npc_south` - Cardinal south position
4. `npc_east` - Cardinal east position
5. `npc_west` - Cardinal west position
6. `npc_northeast` - Diagonal NE position
7. `npc_northwest` - Diagonal NW position
8. `npc_southeast` - Diagonal SE position
9. `npc_southwest` - Diagonal SW position
10. `npc_far` - Short range test (64px)
11. `npc_disabled` - Face player disabled
12. (Center serves as rotation test)
## Implementation Review
### Code Quality Checks
✅ **Direction Calculation Algorithm**
- 2x threshold prevents flickering
- Handles all 8 directions correctly
- Edge cases handled (zero distance)
- Performance: O(1) calculation
✅ **Animation Integration**
- Idle animations for all 8 directions
- FlipX support for left-facing
- Graceful fallback if animation missing
- Change detection prevents redundant plays
✅ **Distance-Based Activation**
- Squared distance for performance
- Configurable range (default 96px)
- Only updates when in range
- Smooth transitions
## Testing Instructions
### Run Unit Tests
```javascript
// In browser console
await import('./planning_notes/npc/npc_behaviour/phase2_direction_tests.js?v=1');
runDirectionTests();
```
### Test with Actual NPC
```javascript
// After loading test scenario
testWithActualBehavior('npc_center');
```
### Load Test Scenario
```javascript
// Load test scenario in game
window.gameScenario = await fetch('scenarios/test-npc-face-player.json').then(r => r.json());
```
## Expected Results
### Success Criteria
- [ ] All 24 unit tests pass
- [ ] All 8 cardinal/diagonal directions work
- [ ] NPCs face player smoothly (no flickering)
- [ ] Multiple NPCs work independently
- [ ] Distance activation works correctly
- [ ] Disabled NPCs don't face player
- [ ] No console errors
- [ ] Performance acceptable (10+ NPCs)
## Known Issues
None identified. Implementation appears solid.
## Next Steps
Once Phase 2 testing completes:
- **Phase 3**: Patrol Behavior testing
- **Phase 4**: Personal Space testing
- **Phase 5**: Ink Integration testing
- **Phase 6**: Hostile visual feedback
## Performance Notes
- Update throttling: 50ms (20 Hz)
- Direction calculation: O(1)
- Animation checks: Change detection only
- Expected FPS impact: < 2% with 10 NPCs
