+# Phase 3: Patrol Behavior - Test Guide
+
+## Overview
+
+Phase 3 focuses on testing and verifying the **Patrol** behavior. This makes NPCs move randomly within defined bounds, creating dynamic, living environments.
+
+**Status**: ✅ Implementation Complete, Ready for Testing
+
+---
+
+## What Was Implemented
+
+### Core Functionality
+
+1. **Random Movement Within Bounds**
+   - NPCs pick random target points within configured bounds
+   - Move toward target using velocity-based physics
+   - Pick new target when reached (< 8px distance)
+
+2. **Timed Direction Changes**
+   - Configurable interval (default: 3000ms)
+   - New random target chosen at each interval
+   - Prevents NPCs from getting "stuck" in patterns
+
+3. **Stuck Detection & Recovery**
+   - Detects when NPC is blocked by collision
+   - 500ms timeout before choosing new direction
+   - Prevents infinite collision loops
+
+4. **Walk Animations**
+   - 8-way walk animations during movement
+   - Direction calculated based on velocity
+   - Smooth animation transitions
+
+5. **Collision Handling**
+   - NPCs collide with walls, chairs, and other objects
+   - Physics-based collision response
+   - Automatic recovery from stuck states
+
+6. **Priority Integration**
+   - Patrol is Priority 2 (overridden by higher priorities)
+   - Face Player (Priority 1) can interrupt patrol
+   - Personal Space (Priority 3) overrides patrol
+

+
+## How to Test
+
+### Setup
+
+1. **Load Test Scenario**:
+   ```javascript
+   window.gameScenario = await fetch('scenarios/test-npc-patrol.json').then(r => r.json());
+   // Then reload game
+   ```
+
+2. **Verify Behavior Manager**:
+   ```javascript
+   console.log('Behavior Manager:', window.npcBehaviorManager);
+   console.log('Registered behaviors:', window.npcBehaviorManager.behaviors.size);
+   ```
+
+---
+
+## Test Procedures
+
+### Test 1: Basic Patrol Movement
+
+**NPC**: `patrol_basic` (blue, position 3,3)
+
+**Configuration**:
+- Speed: 100px/s
+- Interval: 3000ms (3 seconds)
+- Bounds: 6x6 tiles (192x192px)
+
+**Procedure**:
+1. Observe NPC from a distance (don't approach)
+2. Watch for 30 seconds
+
+**Expected Behavior**:
+- ✅ NPC should walk to random points within 6x6 area
+- ✅ Changes direction every 3 seconds
+- ✅ Uses walk animations (8 directions)
+- ✅ Smooth movement, no jittering
+- ✅ Stays within bounds (2-7 tiles from origin)
+- ✅ Direction matches movement (walks forward, not sideways)
+
+**Measurements**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('patrol_basic');
+console.log('Current target:', behavior.patrolTarget);
+console.log('Direction:', behavior.direction);
+console.log('Is moving:', behavior.isMoving);
+console.log('Current state:', behavior.currentState); // Should be 'patrol'
+```
+
+---
+
+### Test 2: Speed Variations
+
+**NPCs**: `patrol_fast` (200px/s) vs `patrol_slow` (50px/s)
+
+**Procedure**:
+1. Observe both NPCs simultaneously
+2. Compare movement speeds visually
+
+**Expected Behavior**:
+- ✅ `patrol_fast` moves noticeably faster (2x basic speed)
+- ✅ `patrol_slow` moves noticeably slower (0.5x basic speed)
+- ✅ Both use correct walk animation frame rate (8 fps)
+- ✅ Animation doesn't look sped up/slowed down (velocity changes, not animation)
+- ✅ Fast NPC reaches targets quicker
+- ✅ Slow NPC appears to "stroll"
+
+**Debug**:
+```javascript
+// Check velocities
+const fast = window.npcManager.npcs.get('patrol_fast')._sprite;
+const slow = window.npcManager.npcs.get('patrol_slow')._sprite;
+console.log('Fast velocity:', Math.sqrt(fast.body.velocity.x**2 + fast.body.velocity.y**2));
+console.log('Slow velocity:', Math.sqrt(slow.body.velocity.x**2 + slow.body.velocity.y**2));
+// Fast should be ~200, Slow should be ~50
+```
+
+---
+
+### Test 3: Direction Change Intervals
+
+**NPCs**: Various intervals
+
+- `patrol_fast`: 2000ms (2 seconds)
+- `patrol_basic`: 3000ms (3 seconds)
+- `patrol_slow`: 5000ms (5 seconds)
+
+**Procedure**:
+1. Time direction changes with a stopwatch
+2. Observe for 30 seconds
+3. Count direction changes
+
+**Expected Results**:
+- ✅ `patrol_fast`: ~15 direction changes in 30s
+- ✅ `patrol_basic`: ~10 direction changes in 30s
+- ✅ `patrol_slow`: ~6 direction changes in 30s
+- ✅ Changes are roughly consistent (±10%)
+- ✅ NPC picks different target each time (not same point)
+
+**Debug**:
+```javascript
+// Monitor direction changes
+const behavior = window.npcBehaviorManager.getBehavior('patrol_basic');
+let lastTarget = null;
+setInterval(() => {
+    if (JSON.stringify(behavior.patrolTarget) !== lastTarget) {
+        console.log('Direction changed:', behavior.patrolTarget);
+        lastTarget = JSON.stringify(behavior.patrolTarget);
+    }
+}, 100);
+```
+
+---
+
+### Test 4: Bounds Validation
+
+**NPC**: `patrol_basic` (6x6 tile bounds)
+
+**Bounds Configuration**:
+```json
+{
+  "x": 64,
+  "y": 64,
+  "width": 192,
+  "height": 192
+}
+```
+
+**World Coordinates**: (64, 64) to (256, 256)
+
+**Procedure**:
+1. Observe NPC for 1 minute
+2. Note maximum/minimum X and Y positions reached
+
+**Expected Behavior**:
+- ✅ NPC X position: 64 ≤ X ≤ 256
+- ✅ NPC Y position: 64 ≤ Y ≤ 256
+- ✅ NPC never leaves bounds area
+- ✅ Targets are distributed throughout bounds (not clustered)
+
+**Debug**:
+```javascript
+// Track bounds violations
+const behavior = window.npcBehaviorManager.getBehavior('patrol_basic');
+const sprite = window.npcManager.npcs.get('patrol_basic')._sprite;
+const bounds = behavior.config.patrol.worldBounds;
+
+setInterval(() => {
+    const x = sprite.x;
+    const y = sprite.y;
+    if (x < bounds.x || x > bounds.x + bounds.width ||
+        y < bounds.y || y > bounds.y + bounds.height) {
+        console.error('❌ BOUNDS VIOLATION:', {x, y, bounds});
+    }
+}, 100);
+```
+
+---
+
+### Test 5: Stuck Detection & Recovery
+
+**NPC**: `patrol_stuck_test`
+
+**Setup**:
+1. Place obstacles in patrol area (if possible)
+2. Observe NPC encountering obstacles
+
+**Procedure**:
+1. Watch NPC patrol
+2. Wait for NPC to hit a wall or obstacle
+3. Observe recovery behavior
+
+**Expected Behavior**:
+- ✅ NPC walks toward wall/obstacle
+- ✅ NPC stops when colliding (blocked state)
+- ✅ After ~500ms, NPC chooses new direction
+- ✅ New direction avoids the obstacle
+- ✅ NPC doesn't get permanently stuck
+- ✅ No console errors
+
+**Debug**:
+```javascript
+// Monitor stuck states
+const behavior = window.npcBehaviorManager.getBehavior('patrol_stuck_test');
+const sprite = window.npcManager.npcs.get('patrol_stuck_test')._sprite;
+
+setInterval(() => {
+    const isBlocked = sprite.body.blocked.none === false;
+    if (isBlocked) {
+        console.log('🚧 NPC stuck! Timer:', behavior.stuckTimer, 'ms');
+    }
+}, 100);
+```
+
+---
+
+### Test 6: Narrow Area Patrol
+
+**NPCs**:
+- `patrol_narrow_horizontal` (8x1 tiles - horizontal corridor)
+- `patrol_narrow_vertical` (1x5 tiles - vertical corridor)
+
+**Procedure**:
+1. Observe horizontal NPC - should mostly move left/right
+2. Observe vertical NPC - should mostly move up/down
+3. Check animations match movement direction
+
+**Expected Behavior**:
+
+**Horizontal NPC**:
+- ✅ Primarily uses `walk-left` and `walk-right` animations
+- ✅ Rarely uses vertical animations
+- ✅ Stays within 8-tile wide corridor
+- ✅ Smooth horizontal movement
+
+**Vertical NPC**:
+- ✅ Primarily uses `walk-up` and `walk-down` animations
+- ✅ Rarely uses horizontal animations
+- ✅ Stays within 1-tile wide corridor
+- ✅ Smooth vertical movement
+
+---
+
+### Test 7: Patrol + Face Player Interaction
+
+**NPC**: `patrol_with_face` (center, red sprite)
+
+**Configuration**:
+- Patrol: enabled, 100px/s
+- Face Player: enabled, 96px range
+
+**Procedure**:
+1. Stay far from NPC (>3 tiles)
+2. Observe patrol behavior
+3. Approach within 3 tiles
+4. Walk away
+
+**Expected Behavior**:
+
+**When Far (>3 tiles)**:
+- ✅ NPC patrols normally
+- ✅ Uses walk animations
+- ✅ Changes direction every 4 seconds
+- ✅ State: `'patrol'`
+
+**When Near (<3 tiles)**:
+- ✅ NPC stops patrolling
+- ✅ NPC turns to face player
+- ✅ Uses idle animation facing player
+- ✅ Velocity becomes (0, 0)
+- ✅ State: `'face_player'`
+
+**When Leaving**:
+- ✅ NPC resumes patrol after player leaves range
+- ✅ Picks new random target
+- ✅ Resumes walk animations
+- ✅ State returns to `'patrol'`
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('patrol_with_face');
+setInterval(() => {
+    console.log('State:', behavior.currentState,
+                'Is Moving:', behavior.isMoving,
+                'Direction:', behavior.direction);
+}, 500);
+```
+
+---
+
+### Test 8: Small Area Patrol
+
+**NPC**: `patrol_small` (2x2 tiles only)
+
+**Procedure**:
+1. Observe NPC in tiny area
+2. Watch for 30 seconds
+
+**Expected Behavior**:
+- ✅ NPC moves within 2x2 tile area only
+- ✅ Frequent direction changes (targets nearby)
+- ✅ Reaches targets quickly (small distances)
+- ✅ No getting stuck in corners
+- ✅ Smooth transitions despite small space
+
+**Edge Case Check**:
+- Target point might be very close to current position
+- Should still move smoothly, not jitter
+
+---
+
+### Test 9: Patrol Toggle via Ink
+
+**NPC**: `patrol_initially_disabled`
+
+**Procedure**:
+1. Observe NPC initially - should be stationary
+2. Talk to NPC (E key when nearby)
+3. Select "Start patrolling"
+4. Exit conversation - NPC should start moving
+5. Talk again, select "Stop patrolling"
+6. Exit - NPC should stop
+
+**Expected Behavior**:
+
+**Initial State**:
+- ✅ NPC is stationary (idle animation)
+- ✅ NPC faces player when nearby
+- ✅ State: `'face_player'` or `'idle'`
+- ✅ Patrol enabled: `false`
+
+**After "Start patrolling"**:
+- ✅ Tag `#patrol_mode:on` processed
+- ✅ NPC starts moving after conversation ends
+- ✅ State changes to `'patrol'`
+- ✅ Uses walk animations
+- ✅ Patrol enabled: `true`
+
+**After "Stop patrolling"**:
+- ✅ Tag `#patrol_mode:off` processed
+- ✅ NPC stops moving
+- ✅ Returns to idle/face player behavior
+- ✅ Patrol enabled: `false`
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('patrol_initially_disabled');
+console.log('Patrol enabled:', behavior.config.patrol.enabled);
+console.log('Current state:', behavior.currentState);
+```
+
+---
+
+## Performance Testing
+
+### Test: Multiple Patrolling NPCs
+
+**Procedure**:
+1. Load test scenario (9 NPCs, 8 patrolling)
+2. Let all NPCs patrol simultaneously
+3. Monitor FPS and performance
+
+**Expected Performance**:
+- ✅ Stable 60 FPS with 8 patrolling NPCs
+- ✅ No visible lag or stuttering
+- ✅ Smooth animations for all NPCs
+- ✅ CPU usage reasonable (<20% spike)
+
+**Debug**:
+```javascript
+// Monitor FPS
+let lastTime = performance.now();
+let frames = 0;
+setInterval(() => {
+    const now = performance.now();
+    const fps = frames / ((now - lastTime) / 1000);
+    console.log('FPS:', fps.toFixed(1));
+    frames = 0;
+    lastTime = now;
+}, 1000);
+window.game.scene.scenes[0].events.on('postupdate', () => frames++);
+```
+
+---
+
+## Animation Testing
+
+### Expected Animation States
+
+**While Patrolling**:
+- Animation: `npc-{npcId}-walk-{direction}`
+- Direction: Matches movement vector
+- Frame rate: 8 fps
+- FlipX: true for left-facing directions
+
+**When Reaching Target**:
+- Brief moment at target (< 8px)
+- May show idle frame for 1 frame
+- Quickly picks new target and resumes walking
+
+**When Blocked**:
+- Walk animation continues briefly
+- After 500ms stuck timeout, picks new direction
+- Changes to new walk animation
+
+### Debug Animations
+
+```javascript
+const sprite = window.npcManager.npcs.get('patrol_basic')._sprite;
+console.log('Current animation:', sprite.anims.currentAnim?.key);
+console.log('Is playing:', sprite.anims.isPlaying);
+console.log('FlipX:', sprite.flipX);
+```
+
+---
+
+## Edge Cases
+
+### Edge Case 1: Target Point on Wall
+
+**Scenario**: Random target is inside a wall
+
+**Expected**:
+- NPC walks toward target
+- Hits wall, becomes blocked
+- Stuck timer triggers after 500ms
+- New target chosen (likely not in wall)
+- ✅ No infinite loop
+
+### Edge Case 2: NPC Starts Outside Bounds
+
+**Scenario**: NPC spawned outside configured patrol bounds
+
+**Handling**:
+- Bounds auto-expand to include starting position (implemented in parseConfig)
+- ✅ NPC patrols normally
+- ✅ Console warning logged
+
+**Test**:
+```javascript
+// Check if bounds were expanded
+const behavior = window.npcBehaviorManager.getBehavior('patrol_basic');
+const sprite = window.npcManager.npcs.get('patrol_basic')._sprite;
+console.log('Start pos:', sprite.x, sprite.y);
+console.log('Bounds:', behavior.config.patrol.worldBounds);
+// Bounds should include start position
+```
+
+### Edge Case 3: Very Small Bounds
+
+**Scenario**: Bounds smaller than NPC sprite
+
+**Expected**:
+- NPC still picks targets within bounds
+- May appear to jitter if bounds very tiny
+- Should not crash
+
+### Edge Case 4: Reached Target Exactly
+
+**Scenario**: NPC reaches within 8px of target
+
+**Expected**:
+- ✅ New target chosen immediately
+- ✅ No stopping at target (seamless transition)
+- ✅ Direction changes smoothly
+
+### Edge Case 5: Direction Change During Collision
+
+**Scenario**: Direction interval expires while NPC is stuck
+
+**Expected**:
+- ✅ New target chosen
+- ✅ Stuck timer resets
+- ✅ NPC attempts to move to new target
+- ✅ If still blocked, stuck timer continues
+
+---
+
+## Common Issues
+
+### Issue 1: NPC Not Moving
+
+**Symptoms**: NPC stationary, not patrolling
+
+**Possible Causes**:
+1. Patrol disabled: `behavior.config.patrol.enabled === false`
+2. No bounds configured: `behavior.config.patrol.worldBounds === null`
+3. Higher priority behavior active (face player, personal space)
+4. NPC stuck permanently (rare)
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('npc_id');
+console.log('Patrol enabled:', behavior.config.patrol.enabled);
+console.log('Bounds:', behavior.config.patrol.worldBounds);
+console.log('Current state:', behavior.currentState);
+console.log('Patrol target:', behavior.patrolTarget);
+```
+
+**Fix**:
+- Enable patrol: `window.npcGameBridge.setNPCPatrol('npc_id', true)`
+- Check state priority
+
+---
+
+### Issue 2: NPC Leaving Bounds
+
+**Symptoms**: NPC wanders outside configured area
+
+**Possible Causes**:
+1. Bounds in room coordinates, not world coordinates
+2. Bounds calculation error
+3. Collision pushing NPC out
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('npc_id');
+const sprite = window.npcManager.npcs.get('npc_id')._sprite;
+const bounds = behavior.config.patrol.worldBounds;
+console.log('NPC pos:', sprite.x, sprite.y);
+console.log('Bounds:', bounds);
+console.log('In bounds?',
+    sprite.x >= bounds.x && sprite.x <= bounds.x + bounds.width &&
+    sprite.y >= bounds.y && sprite.y <= bounds.y + bounds.height
+);
+```
+
+**Note**: Bounds are converted to world coordinates in parseConfig()
+
+---
+
+### Issue 3: NPC Getting Stuck
+
+**Symptoms**: NPC stops moving for >1 second
+
+**Possible Causes**:
+1. Stuck in corner with bad target
+2. Collision not resolving properly
+3. Stuck detection not working
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('npc_id');
+const sprite = window.npcManager.npcs.get('npc_id')._sprite;
+console.log('Blocked:', sprite.body.blocked);
+console.log('Stuck timer:', behavior.stuckTimer);
+console.log('Target:', behavior.patrolTarget);
+```
+
+**Expected**: Stuck timer should reach 500ms and reset
+
+---
+
+### Issue 4: Wrong Animation
+
+**Symptoms**: Walk animation doesn't match direction
+
+**Possible Causes**:
+1. Direction calculation error
+2. Animation not created (using fallback idle)
+3. FlipX not applied for left directions
+
+**Debug**:
+```javascript
+const behavior = window.npcBehaviorManager.getBehavior('npc_id');
+const sprite = window.npcManager.npcs.get('npc_id')._sprite;
+console.log('Direction:', behavior.direction);
+console.log('Animation:', sprite.anims.currentAnim?.key);
+console.log('FlipX:', sprite.flipX);
+console.log('Velocity:', sprite.body.velocity);
+```
+
+---
+
+## Success Criteria

+
+1. [ ] Basic patrol works (random movement in bounds)
+2. [ ] Speed variations work correctly (fast/slow)
+3. [ ] Direction changes occur at configured intervals
+4. [ ] NPCs stay within configured bounds
+5. [ ] Stuck detection recovers from collisions
+6. [ ] Narrow area patrols work (corridors)
