Fix NPC interaction and event handling issues
- Added a visual problem-solution summary for debugging NPC event handling.
- Resolved cooldown bug in NPCManager by implementing explicit null/undefined checks.
- Modified PersonChatMinigame to prioritize event parameters over state restoration.
- Updated security guard dialogue in Ink scenarios to improve interaction flow.
- Adjusted vault key parameters in npc-patrol-lockpick.json for consistency.
- Changed inventory stylesheet references to hud.css in test HTML files for better organization.
feat(combat): Integrate chair kicking with punch mechanic
Update chair interaction to use the punch system instead of direct kicking:
**Changes to interactions.js:**
- Modified swivel chair interaction to trigger player punch instead of
directly applying kick velocity
- Simplified chair interaction handler to just call playerCombat.punch()
**Changes to player-combat.js:**
- Extended checkForHits() to detect chairs in punch range and direction
- Added kickChair() method that applies the same velocity calculation:
- Calculates direction from player to chair
- Applies 1200 px/s kick force in that direction
- Triggers spin direction calculation for visual rotation
- Adds visual feedback (flash chair, light screen shake)
- Chairs now respond to punch AOE damage like hostile NPCs
Now clicking a chair or pressing 'E' near it triggers a punch, and if the
chair is in punch range and facing direction, it gets kicked with the
original velocity physics. Multiple chairs can be kicked with one punch.
feat(combat): Implement hostile NPC behavior and final integration (Phase 6-7)
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.
feat(combat): Add feedback, UI, and combat mechanics (Phase 2-5)
Implement comprehensive combat feedback, UI, and mechanics:
**Phase 2: Enhanced Feedback Systems**
- damage-numbers.js: Floating damage numbers with object pooling
- screen-effects.js: Screen flash and shake for combat feedback
- sprite-effects.js: Sprite tinting, flashing, and visual effects
- attack-telegraph.js: Visual indicators for incoming NPC attacks
**Phase 3: UI Components**
- health-ui.js: Player health display as hearts (5 hearts, shows when damaged)
- npc-health-bars.js: Health bars above hostile NPCs with color coding
- game-over-screen.js: KO screen with restart/main menu options
**Phase 4-5: Combat Mechanics**
- player-combat.js: Player punch system with AOE directional damage
- npc-combat.js: NPC attack system with telegraph and cooldowns
- Modified interactions.js to trigger punch on hostile NPC interaction
- Integrated all systems into game.js create() and update() loops
Combat now functional with complete visual/audio feedback pipeline.
Player can punch hostile NPCs, NPCs can attack player, health tracking works.
feat(combat): Add hostile NPC system foundation (Phase 0-1)
Implement core hostile NPC combat system infrastructure:
- Add #hostile tag handler to chat-helpers.js for Ink integration
- Fix security-guard.ink to use proper hub pattern with -> hub instead of -> END
- Add #hostile:security_guard tags to hostile conversation paths
- Create combat configuration system (combat-config.js)
- Create combat event constants (combat-events.js)
- Implement player health tracking system with HP and KO state
- Implement NPC hostile state management with HP tracking
- Add combat debug utilities for testing
- Add error handling utilities for validation
- Integrate combat systems into game.js create() method
- Create test-hostile.ink for testing hostile tag system
This establishes the foundation for hostile NPC behavior, allowing NPCs to
become hostile through Ink dialogue and tracking health for both player and NPCs.
docs(npc): Apply codebase-verified corrections to hostile NPC plans
Apply critical corrections based on actual codebase verification:
CORRECTIONS.md (Updated):
- ✅ Confirms #exit_conversation tag ALREADY IMPLEMENTED
* Location: person-chat-minigame.js line 537
* No handler needed in chat-helpers.js

- Face the player when nearby
- Patrol areas with random movement
- Maintain personal space by backing away
- Display hostile states with visual feedback
- Be controlled via Ink story tags
## New Files Created
**js/systems/npc-behavior.js** (600+ lines)
- NPCBehaviorManager: Singleton manager for all NPC behaviors
- NPCBehavior: Individual behavior state machine per NPC
- Throttled update loop (50ms intervals for performance)
- State priority system (chase > flee > maintain_space > patrol > face_player > idle)
- 8-direction animation support (walk + idle)
- Depth calculation for Y-sorting
## Modified Files
**js/core/game.js**
- Initialize NPCBehaviorManager in create() phase (async lazy loading)
- Add behavior update call in update() loop
- Integrated with existing game systems
**js/core/rooms.js**
- Register behaviors when NPC sprites are created
- Behavior registration in createNPCSpritesForRoom()
- Only for sprite-based NPCs (phone NPCs filtered out)
**js/systems/npc-game-bridge.js**
- Added 4 behavior control methods:
- setNPCHostile(npcId, hostile)

- setNPCPatrol(npcId, enabled)
- setNPCPersonalSpace(npcId, distance)
- Auto-trigger hostile state based on influence threshold
- Exposed global helpers for Ink integration
**js/minigames/person-chat/person-chat-conversation.js**
- Added 4 tag handlers for Ink behavior control:
- #hostile / #hostile:false
- #influence:25 / #influence:-50
- #patrol_mode:on / #patrol_mode:off
- #personal_space:64
- Integrated with existing tag processing system
## Features Implemented
### Face Player (Priority 1)

- Stuck detection and recovery (500ms timeout)
- Collision handling with walls/chairs
- Walk animations with 8-way movement
- Default speed: 100 px/s
### Personal Space (Priority 3)
- Back away when player within 48px (1.5 tiles)
- Slow backing: 5px increments at 30 px/s
- Maintains eye contact while backing
- Wall collision detection (can't back through walls)
- Stays within interaction range (64px)
### Hostile State (Visual)
- Red tint (0xff6666) when hostile
- Influence-based auto-trigger (threshold: -50)
