This document outlines the implementation of a modular, maintainable NPC behavior system for Break Escape. The system will enable NPCs to exhibit dynamic behaviors including player awareness, patrolling, personal space maintenance, and hostility states.
**Key Architecture Points**:
- **Rooms never unload** - NPCs persist throughout the game session
- **Simple lifecycle** - Behaviors registered once when NPC sprite created
- **Real-time updates** - Depth calculated every frame for proper Y-sorting
- **Phaser physics** - Uses `immovable: true` (same as player)

// NPC collision (npc-sprites.js) - CORRECT, DO NOT CHANGE
sprite.body.setSize(18, 10); // Wider for better hit detection
sprite.body.setOffset(23, 50); // Adjusted for wider box
sprite.body.immovable = true; // Can't be pushed (same as player)

player.body.setSize(15, 10); // Narrower for tighter control
player.body.setOffset(25, 50); // Different offset
player.body.immovable = true; // Can't be pushed (same as NPCs)
```
**Why NPCs are wider:**
- Better hit detection during patrol (moving NPCs need larger collision)
- Prevents player from easily slipping past patrolling guards
- Both use `immovable: true` (correct for both player and NPCs)
- Both are 10px tall and positioned at sprite feet
**Do not "match player collision"** - the difference is intentional.
**About `immovable: true`:**
- Means sprite cannot be *pushed* by other sprites
- Does NOT prevent sprite from moving itself via velocity or position
- Same physics setting used by player
- Allows collision detection while maintaining control
**Do not "match player collision"** - the width difference is intentional.
### Room Loading and NPC Lifecycle
**CRITICAL UNDERSTANDING**: Rooms are **never unloaded** in Break Escape.
**How it works:**
1. Rooms load once when player first enters them
2. Rooms stay loaded for entire game session
3. All NPCs persist throughout the game
4. `unloadNPCSprites()` function exists but is never called
**Implications for behavior system:**
- ✅ **No lifecycle management needed** - sprites never destroyed
- ✅ **No unregister function needed** - behaviors persist naturally
- ✅ **No state persistence needed** - NPCs maintain state automatically
- ✅ **Simpler implementation** - no cleanup logic required
**Code pattern:**
```javascript
// Behavior registration (once per NPC, persists forever)
window.npcBehaviorManager.registerBehavior(npcId, sprite, config);
// No corresponding unregister needed - sprite lives for entire game
```
**Why this matters:**
- Dramatically simplifies implementation (no room transition handling)
- Reduces bugs (no stale sprite references possible)
- Better performance (no destroy/recreate overhead)
- Natural state persistence (behaviors never reset)

# Quick Reference: Key Takeaways from Code Review
**For**: Developers implementing NPC behavior system
**TL;DR**: Major simplifications after maintainer clarifications
---
## 🎉 Good News
Your implementation just got **much simpler**! Four major concerns were resolved:
### 1. ✅ No Lifecycle Management Needed
**Why**: Rooms never unload in Break Escape
**Impact**: No `unregisterBehaviorsForRoom()` method needed
**Code**: Just register once, behaviors persist forever
### 2. ✅ Physics Config is Correct
**Why**: `immovable: true` means "can't be pushed" (not "can't move")
**Impact**: No changes to NPC or player physics needed
**Code**: Keep current configuration
### 3. ✅ No Depth Caching Needed
**Why**: Phaser handles depth sorting efficiently
**Impact**: Just call `setDepth()` every frame
**Code**: Simpler update loop
### 4. ✅ State Persists Automatically
**Why**: NPCs never destroyed, exist throughout game
**Impact**: No state persistence system needed
**Code**: Behavior properties naturally persist
---
## ⚠️ Still Need to Fix (Phase -1 - 1 day)
### 1. Walk Animations
**File**: `js/systems/npc-sprites.js`
**Issue**: Only idle animations exist, need 4-direction walk
**Fix**: Add walk-up, walk-down, walk-left, walk-right animations
### 2. Player Position Access
**File**: `js/systems/npc-behavior.js`
**Issue**: Update loop needs player coordinates
**Fix**: Add `const player = window.player; if (!player) return;`
### 3. Phone NPC Filtering
**File**: `js/core/rooms.js`
**Issue**: Phone-only NPCs shouldn't get behaviors
**Fix**: Add type check before `registerBehavior()`
---
## 📋 Implementation Checklist
```
Phase -1 (1 day - MUST DO FIRST):
[ ] Add walk animations (4 directions)
[ ] Add player position null check
[ ] Add phone NPC type filtering
Phase 0 (1 day):
[ ] Verify animations work
[ ] Add roomId to NPC data
[ ] Test basic setup
Phase 1-7 (2 weeks):
[ ] Implement behaviors as planned
[ ] No lifecycle management code
[ ] No physics changes
[ ] No state persistence
```
---
## 🚫 Don't Do This (Common Mistakes)
### ❌ Don't add lifecycle management
```javascript
// ❌ BAD - Not needed!
unregisterBehaviorsForRoom(roomId) { ... }
```
**Why**: Rooms never unload, sprites never destroyed
### ❌ Don't change immovable physics
```javascript
// ❌ BAD - Don't change this!
sprite.body.immovable = false; // for patrol
```
**Why**: Current config is correct, immovable doesn't prevent movement
### ❌ Don't cache depth values
```javascript
// ❌ BAD - Don't optimize prematurely!
if (newDepth !== this.lastDepth) {
this.sprite.setDepth(newDepth);
}
```
**Why**: Must update every frame for Y-sorting, performance is fine
### ❌ Don't add state persistence
```javascript
// ❌ BAD - Not needed!
saveNPCState() {
return { hostile, influence, direction };
}
```
**Why**: State persists naturally, NPCs never destroyed
---
## ✅ Do This Instead (Correct Patterns)
### ✅ Simple registration (no unregister)
```javascript
// ✅ GOOD - Register once, persists forever
registerBehavior(npcId, sprite, config) {
const behavior = new NPCBehavior(npcId, sprite, config);
this.behaviors.set(npcId, behavior);
}
```
### ✅ Keep current physics
```javascript
// ✅ GOOD - Already correct in codebase
sprite.body.immovable = true; // Can't be pushed
sprite.body.setVelocity(vx, vy); // But can move itself
```
### ✅ Always update depth
```javascript
// ✅ GOOD - Simple, correct
updateDepth() {
const depth = this.sprite.y + (this.sprite.displayHeight / 2) + 0.5;
this.sprite.setDepth(depth);
}
```
### ✅ Natural state persistence
```javascript
// ✅ GOOD - State just exists in object
this.hostile = true; // Persists naturally
this.influence = 50; // No save/load needed
```

## 📞 Still Confused?
### "Do rooms really never unload?"
**Yes.** Verified with maintainer. Rooms load once and stay loaded entire game.
### "Can immovable sprites really move?"
**Yes.** `immovable: true` means "can't be pushed by OTHER sprites". Sprite can still move itself via velocity/position changes. Same as player.
### "Why not optimize depth updates?"
**Premature optimization.** Update every frame is simple and correct. Only optimize if FPS drops below 50 with 10+ NPCs. Profile first.
### "What about NPC state when changing rooms?"
**State persists automatically.** Since NPCs never destroyed, all properties (hostile, influence, direction) naturally persist throughout game.
---
## 🎯 Bottom Line
**Before review**: Complex system with lifecycle management, 3-4 weeks, 85-90% success
**After review**: Simple system with no lifecycle, 3 weeks, 95-98% success
**Recommendation**: ✅ Proceed with confidence after Phase -1 (1 day)

## 🚦 Review Status
| Review | Status | Date | Findings |
|--------|--------|------|----------|
| Initial Review | ✅ Complete | Nov 9, 2025 | 6 Critical, 4 Medium |
| Extended Review | ✅ Complete | Nov 9, 2025 | 5 Critical, 3 Medium |
| **Total Issues** | **11 Critical** | - | **2 Blockers** |
---
## 🔴 Critical Findings Summary
### BLOCKER Issues (Must Fix):
1. **Behavior Lifecycle** - NPCs destroyed but behaviors persist → crashes
2. **Missing Player Position** - Update loop can't access player → no behaviors work
### CRITICAL Issues (Will Fail):
3. **Walk Animations** - Not created at right time → patrol fails
4. **Patrol Collision** - Physics config wrong → NPCs walk through walls
5. **Phone NPCs** - No type filtering → errors on registration
6. **RoomId Missing** - Not stored in NPC data → patrol bounds fail
7. **Integration Point** - Registration happens too early → sprite references invalid
### MAJOR Issues (Will Bug):
8. **Environment Collisions** - Function doesn't exist → patrol pathfinding broken
9. **Patrol Bounds** - No validation → NPCs spawn outside bounds
10. **Depth Updates** - Not explicit in update loop → Y-sorting broken
11. **Personal Space** - No wall collision check → NPCs back into walls

# NPC Behavior Plan Update Summary
**Date**: November 9, 2025
**Updates Applied**: Based on comprehensive code review and maintainer clarifications
---
## 🎯 What Changed
### Major Clarifications from Maintainer
1. **Rooms Never Unload** ✅
- Original assumption: Rooms unload when player leaves
- **Reality**: Rooms load once and persist for entire game session
- **Impact**: No lifecycle management needed, dramatically simpler implementation
2. **Physics Configuration is Correct** ✅
- Original concern: `immovable: true` might break patrol
- **Reality**: `immovable: true` is correct (same as player), allows movement via velocity
- **Impact**: No physics changes needed
3. **Depth Updates Don't Need Caching** ✅
- Original suggestion: Cache depth for performance
- **Reality**: Must update every frame for Y-sorting, performance is acceptable
- **Impact**: Simpler code, one less optimization to maintain
4. **State Persists Naturally** ✅
- Original recommendation: Add state persistence system
- **Reality**: NPCs persist throughout game, state maintained automatically
- **Impact**: No persistence code needed
