Complete hostile NPC combat system with chase behavior and integration: **Phase 6: Hostile NPC Behavior** - Modified npc-behavior.js determineState() to check hostile state from npcHostileSystem - Implemented updateHostileBehavior() with chase and attack logic: - NPCs chase player when hostile and in aggro range - NPCs stop and attack when in attack range - NPCs use directional movement with proper animations - Integration with npcCombat system for attack attempts - Added KO state check to prevent KO'd NPCs from acting **Phase 7: Final Integration** - Modified player.js to disable movement when player is KO - Added visual KO effect (50% alpha) to NPC sprites in npc-hostile.js - Connected all combat systems end-to-end: - Ink dialogue → hostile tag → hostile state → chase behavior → combat - Player interaction → punch → NPC damage → KO → visual feedback - NPC chase → attack → player damage → HP UI → game over Full combat loop now functional: hostile NPCs chase and attack player, player can punch hostile NPCs, complete visual/audio feedback, game over on KO.

/**
|
|
* NPC Behavior System - Core Behavior Management
|
|
*
|
|
* Manages all NPC behaviors including:
|
|
* - Face Player: Turn to face player when nearby
|
|
* - Patrol: Random movement within area (using EasyStar.js pathfinding)
|
|
* - Personal Space: Back away if player too close
|
|
* - Hostile: Red tint, future chase/flee behaviors
|
|
*
|
|
* Architecture:
|
|
* - NPCBehaviorManager: Singleton manager for all NPC behaviors
|
|
* - NPCBehavior: Individual behavior instance per NPC
|
|
* - NPCPathfindingManager: Manages EasyStar pathfinding per room
|
|
*
|
|
* Lifecycle:
|
|
* - Manager initialized once in game.js create()
|
|
* - Behaviors registered per-room when sprites created
|
|
* - Updated every frame (throttled to 50ms)
|
|
* - Rooms never unload, so no cleanup needed
|
|
*
|
|
* @module npc-behavior
