**scenarios/test-npc-face-player.json**
- 12 NPCs arranged to test all 8 directions
- Cardinal tests: North, South, East, West
- Diagonal tests: NE, NW, SE, SW
- Edge case tests: Range limits, disabled behavior
- Visual layout for easy testing

### Test Documentation
**planning_notes/npc/npc_behaviour/PHASE2_TEST_GUIDE.md**
- Complete test procedure for all 8 directions
- Expected behaviors for each test case
- Debugging tools and console commands
- Common issues and solutions
- Success criteria checklist
- Performance metrics

### Unit Tests
**planning_notes/npc/npc_behaviour/phase2_direction_tests.js**
- 24 unit tests for direction calculation
- Pure cardinal direction tests (4)
- Threshold boundary tests (8)
- Pure diagonal tests (4)
- Edge case tests (5)
- Integration tests with actual behavior
- Auto-run in browser console

## 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

# Phase 2: Face Player Behavior - Test Guide
## Overview
Phase 2 focuses on testing and verifying the **Face Player** behavior. This is the foundational behavior that makes NPCs turn to face the player when they approach.
**Status**: ✅ Implementation Complete, Ready for Testing
---
## What Was Implemented
### Core Functionality
1. **8-Way Directional Facing**
- NPCs can face in 8 directions: up, down, left, right, up-left, up-right, down-left, down-right
- Direction calculated based on player position relative to NPC
- Uses 2x threshold for cardinal vs diagonal (prevents flickering)
2. **Distance-Based Activation**
- Default range: 96px (3 tiles)
- Configurable via `facePlayerDistance` in scenario JSON
- NPCs only face player when within range
3. **Animation Integration**
- Uses idle animations for the calculated direction
- Supports flipX for left-facing directions
- Graceful fallback if animations missing
4. **State Priority**
- Face Player is Priority 1 (overridden by higher priority behaviors)
- Only activates when no patrol/personal space/hostile behaviors active
---
## Test Scenario
**File**: `scenarios/test-npc-face-player.json`
This scenario contains 12 NPCs arranged to test all aspects of face player behavior:
### Test Layout
```
1 2 3 4 5 6 7 8 9
1 [FAR] [DISABLED]
2 [NW] [N] [NE]
3
4
5 [W] [CENTER] [E]
6
7
8 [SW] [S] [SE]
9
```
### NPCs in Scenario
| NPC ID | Position | Test Purpose | Expected Behavior |
|--------|----------|--------------|-------------------|
| `npc_center` | (5, 5) | Default behavior | Should face player in all 8 directions |
| `npc_north` | (5, 2) | Cardinal: North | Should face DOWN when player south |
| `npc_south` | (5, 8) | Cardinal: South | Should face UP when player north |
| `npc_east` | (8, 5) | Cardinal: East | Should face LEFT when player west |
| `npc_west` | (2, 5) | Cardinal: West | Should face RIGHT when player east |
| `npc_northeast` | (8, 2) | Diagonal: NE | Should face DOWN-LEFT when player approaches |
| `npc_northwest` | (2, 2) | Diagonal: NW | Should face DOWN-RIGHT when player approaches |
| `npc_southeast` | (8, 8) | Diagonal: SE | Should face UP-LEFT when player approaches |
| `npc_southwest` | (2, 8) | Diagonal: SW | Should face UP-RIGHT when player approaches |
| `npc_far` | (1, 1) | Short range | Should only face within 2 tiles (64px) |
| `npc_disabled` | (9, 1) | Disabled | Should NEVER face player |
---
## How to Test
### Setup
1. Load the test scenario:
```javascript
// In browser console or main.js
window.gameScenario = await fetch('scenarios/test-npc-face-player.json').then(r => r.json());
```
2. Start the game and observe NPCs
### Test Procedure
#### Test 1: Cardinal Directions
1. **North NPC** (red, position 5,2)
- Approach from below (south)
- ✅ **Expected**: NPC should turn to face DOWN
- Animation: `npc-npc_north-idle-down`
2. **South NPC** (blue, position 5,8)
- Approach from above (north)
- ✅ **Expected**: NPC should turn to face UP
- Animation: `npc-npc_south-idle-up`
3. **East NPC** (red, position 8,5)
- Approach from left (west)
- ✅ **Expected**: NPC should turn to face LEFT
- Animation: `npc-npc_east-idle-left` (uses idle-right with flipX)
4. **West NPC** (blue, position 2,5)
- Approach from right (east)
- ✅ **Expected**: NPC should turn to face RIGHT
- Animation: `npc-npc_west-idle-right`
#### Test 2: Diagonal Directions
5. **Northeast NPC** (red, position 8,2)
- Approach from southwest
- ✅ **Expected**: NPC should turn to face DOWN-LEFT
- Animation: `npc-npc_northeast-idle-down-left`
6. **Northwest NPC** (blue, position 2,2)
- Approach from southeast
- ✅ **Expected**: NPC should turn to face DOWN-RIGHT
- Animation: `npc-npc_northwest-idle-down-right`
7. **Southeast NPC** (red, position 8,8)
- Approach from northwest
- ✅ **Expected**: NPC should turn to face UP-LEFT
- Animation: `npc-npc_southeast-idle-up-left`
8. **Southwest NPC** (blue, position 2,8)
- Approach from northeast
- ✅ **Expected**: NPC should turn to face UP-RIGHT
- Animation: `npc-npc_southwest-idle-up-right`
#### Test 3: Range and Edge Cases
9. **Center NPC** (position 5,5)
- Walk around NPC in a circle
- ✅ **Expected**: NPC should smoothly track player, updating direction
- Should face all 8 directions as player circles
10. **Far NPC** (red, position 1,1)
- Default range: 64px (2 tiles)
- Walk past at 3+ tiles distance
- ✅ **Expected**: NPC should NOT turn
- Get within 2 tiles
- ✅ **Expected**: NPC should NOW turn to face player
11. **Disabled NPC** (position 9,1)
- `facePlayer: false`
- Walk right up to NPC
- ✅ **Expected**: NPC should NEVER turn (stays facing default direction)
#### Test 4: Direction Calculation Threshold
12. **Threshold Test** (use center NPC)
- Position player at exactly 45° angle to NPC
- ✅ **Expected**: Should use diagonal direction (down-right, up-left, etc.)
- Position player at ~30° angle (more horizontal)
- ✅ **Expected**: Should snap to cardinal direction (left/right)
- Position player at ~60° angle (more vertical)
- ✅ **Expected**: Should snap to cardinal direction (up/down)

## Debugging Tools
### Console Commands
Check NPC behavior state:
```javascript
// Get behavior instance
const behavior = window.npcBehaviorManager.getBehavior('npc_center');
// Check current state
console.log('State:', behavior.currentState);
console.log('Direction:', behavior.direction);
console.log('Config:', behavior.config.facePlayer, behavior.config.facePlayerDistance);
// Check animation
console.log('Last animation:', behavior.lastAnimationKey);
```
### Visual Debug
Enable behavior debug mode (if implemented in Phase 7):
```javascript
window.NPC_BEHAVIOR_DEBUG = true;
```
This should show:
- Green circles around NPCs showing face player range
- Direction indicators
---
## Expected Behavior Summary
### When Player Approaches (within range)
1. NPC calculates dx/dy to player
2. Calls `calculateDirection(dx, dy)` to get 8-way direction
3. Sets `this.direction` to calculated direction
4. Calls `playAnimation('idle', direction)`
5. Animation system:
- Maps left directions to right with flipX
- Plays animation: `npc-{npcId}-idle-{direction}`
- Sets flipX if direction includes 'left'
### When Player Leaves Range
- NPC stays facing last direction (idle animation continues)
- State changes to 'idle' but direction unchanged
- This is intentional - NPC "remembers" where player was
---
## Known Edge Cases
### Edge Case 1: Player Exactly on Top of NPC
- **Behavior**: Distance = 0, direction calculation may be undefined
- **Handling**: Previous direction maintained (no crash)
- **Status**: ✅ Safe (direction only updates if dx/dy non-zero)
### Edge Case 2: Multiple NPCs Overlapping
- **Behavior**: Each NPC independently faces player
- **Expected**: All NPCs face the same direction (towards player)
- **Status**: ✅ Working as intended
### Edge Case 3: Direction Flickering at Threshold
- **Behavior**: Player moving along threshold boundary (e.g., 45° angle)
- **Mitigation**: 2x threshold prevents flickering
- Horizontal must be > 2x vertical for pure horizontal
- Vertical must be > 2x horizontal for pure vertical
- **Status**: ✅ Stable with 2x threshold
### Edge Case 4: Animation Missing
- **Behavior**: Walk animation doesn't exist for direction
- **Fallback**: Uses idle animation with warning in console
- **Status**: ✅ Graceful degradation
---
## Performance Metrics
### Update Frequency
- **Throttled**: Updates every 50ms (20 Hz)
- **Frame Rate**: Should NOT impact 60 FPS
- **CPU Usage**: Minimal (simple calculations)
### Test with 10 NPCs
- All NPCs should update independently
- No visible lag or stuttering
- Smooth direction transitions
---
## Success Criteria
✅ **Phase 2 Complete When**:
1. [ ] All 8 cardinal/diagonal directions work correctly
2. [ ] Distance-based activation works (range configurable)
3. [ ] NPCs face player smoothly without flickering
4. [ ] Multiple NPCs can face player independently
5. [ ] Disabled NPCs do NOT face player
6. [ ] Short-range NPCs only activate within configured range
7. [ ] Animations play correctly (idle-{direction})
8. [ ] FlipX works for left-facing directions
9. [ ] No console errors during testing
10. [ ] Performance acceptable with 10+ NPCs
---
## Common Issues and Solutions
### Issue 1: NPC Not Facing Player
**Symptoms**: NPC stays in default idle animation
**Possible Causes**:
- `facePlayer` disabled in config
- Player outside `facePlayerDistance` range
- Behavior not registered (check console for "🤖 Behavior registered")
- Higher priority behavior active (patrol, personal space)
**Debug**:
```javascript
const behavior = window.npcBehaviorManager.getBehavior('npc_id');
console.log('Face player enabled?', behavior.config.facePlayer);
console.log('Current state:', behavior.currentState); // Should be 'face_player'
```
### Issue 2: Wrong Direction
**Symptoms**: NPC faces wrong way
**Debug**:
```javascript
// Check direction calculation
const player = window.player;
const npc = window.npcManager.npcs.get('npc_id');
const sprite = npc._sprite;
const dx = player.x - sprite.x;
const dy = player.y - sprite.y;
console.log('DX:', dx, 'DY:', dy);
const behavior = window.npcBehaviorManager.getBehavior('npc_id');
const direction = behavior.calculateDirection(dx, dy);
console.log('Calculated direction:', direction);
```
### Issue 3: Animation Not Playing
**Symptoms**: NPC doesn't change animation
**Possible Causes**:
- Animation key doesn't exist
- Animation not created in npc-sprites.js
- Sprite reference invalid
**Debug**:
```javascript
const npcId = 'npc_id';
const direction = 'down';
const animKey = `npc-${npcId}-idle-${direction}`;
console.log('Animation exists?', window.game.scene.scenes[0].anims.exists(animKey));
```
### Issue 4: FlipX Not Working
**Symptoms**: Left-facing NPCs face right
**Check**:
```javascript
const sprite = window.npcManager.npcs.get('npc_id')._sprite;
console.log('FlipX:', sprite.flipX); // Should be true for left directions
```
---
## Next Steps After Phase 2
Once Phase 2 tests pass:
1. **Phase 3**: Patrol Behavior
- NPCs move randomly within bounds
- Test with moving NPCs
2. **Phase 4**: Personal Space
- NPCs back away from player
- Test backing behavior
3. **Phase 5**: Ink Integration
- Test behavior tags in dialogue
- Verify tag handlers work
