Implemented proper handling for the #end_conversation tag to automatically
close the conversation UI without requiring manual ESC key press.
Changes:
1. Added event listener for 'npc-conversation-ended' event in setupEventListeners()
- Saves NPC state when event is received
- Automatically ends minigame and returns to game
- Verifies event is for current NPC
2. Updated showCurrentDialogue() to detect graceful conversation endings
- Checks for #end_conversation tag when story reaches hasEnded
- If tag present, waits for event handler instead of showing manual exit message
- Preserves manual exit message for unexpected/error END states
Flow:
- Ink script: #end_conversation -> DONE
- PhoneChatConversation processes tag and dispatches npc-conversation-ended event
- PersonChatMinigame receives event and automatically closes
- Player sees smooth transition back to game
This eliminates the "(End of conversation - press ESC to exit)" message
for normal conversation endings while preserving it as a safety fallback.
BREAKING CHANGE: Unified relationship variable naming
Old System (Per-NPC Variables):
- Dr. Chen: npc_chen_rapport with #rapport_gained/lost tags
- Director Netherton: npc_netherton_respect with #respect_gained/lost tags
- Haxolottle: npc_haxolottle_friendship_level with #friendship_gained/lost tags
New System (Unified Influence):
- Dr. Chen: npc_chen_influence with #influence_gained/lost tags
- Director Netherton: npc_netherton_influence with #influence_gained/lost tags
- Haxolottle: npc_haxolottle_influence with #influence_gained/lost tags
Benefits:
- Consistent scoring system across all NPCs
- Simpler to understand and balance
- Unified tag system (#influence_gained/lost)
- Messages still customized per NPC based on their personality
Files Changed:
- dr_chen_ongoing_conversations.ink: rapport → influence
- chen_hub.ink: rapport → influence
- netherton_ongoing_conversations.ink: respect → influence
- netherton_hub.ink: respect → influence
- haxolottle_ongoing_conversations.ink: friendship_level → influence
- haxolottle_hub.ink: friendship_level → influence
- PersonChatConversation.js: Updated getInfluenceMessage() for unified system
- Now detects NPC ID and provides appropriate messages
- Supports legacy tag names for backward compatibility
- INK_BEST_PRACTICES.md: Updated all examples and documentation
- Variable naming conventions
- Tag system documentation
- All code examples
- NPC-specific sections
- NPC_HUB_ARCHITECTURE.md: Updated influence system documentation
- Recompiled all hub JSON files
Messages by NPC:
- Dr. Chen: "Dr. Chen appreciates that" / "Dr. Chen is disappointed"
- Netherton: "Director Netherton approves" / "Director Netherton is displeased"
- Haxolottle: "Haxolottle likes that" / "Haxolottle seems disappointed"
All files compile successfully with unified influence system.
BREAKING CHANGE: Updated conversation ending behavior
Old Pattern (WRONG):
- Conversations ended with #exit_conversation
- Diverted to -> END (lost state)
- Game code navigated back to mission_hub
- State not preserved between interactions
New Pattern (CORRECT):
- Conversations end with #end_conversation
- Divert to -> mission_hub (preserves state)
- Game code closes UI window
- Next interaction resumes from mission_hub with full context
Why This Matters:
- State preservation: NPC remembers where conversation left off
- Flexible re-entry: Player can talk to NPC multiple times
- Context awareness: Hub can show different options based on prior discussions
Files Changed:
- All *_ongoing_conversations.ink files: Updated conversation_end knots
- Changed #exit_conversation -> #end_conversation
- Changed -> END -> -> mission_hub
- PersonChatConversation.js: Renamed handleExitConversation -> handleEndConversation
- Now dispatches 'npc-conversation-ended' event to close UI
- Ink handles state preservation via -> mission_hub
- PhoneChatConversation.js: Same changes as PersonChatConversation
- INK_BEST_PRACTICES.md: Updated documentation with correct pattern
- Fixed conversation ending examples
- Updated checklists
- Added state preservation explanation
- NPC_HUB_ARCHITECTURE.md: Updated mission hub flow documentation
- Recompiled all hub JSON files
This ensures conversation state is properly maintained across
multiple interactions with the same NPC within a play session.
Influence Tags System:
- Add #rapport_gained/lost:X tags for Dr. Chen throughout all conversations
- Add #respect_gained/lost:X tags for Director Netherton
- Add #friendship_gained/lost:X tags for Haxolottle
- Tags automatically added after every relationship variable change
- Small changes (±2-5) for minor interactions
- Medium changes (±5-10) for meaningful moments
- Large changes (±10-15) for major trust/betrayal moments
Conversation Handler Updates:
- PersonChatConversation: Add handleInfluenceGained/Lost methods
- PhoneChatConversation: Add tag processing support
- Dispatch 'npc-influence-change' events for UI layer
- Context-appropriate messages based on NPC type and amount
Documentation:
- Create INK_BEST_PRACTICES.md with comprehensive patterns
- Hub architecture and mission_hub pattern
- Influence tags system with examples
- External functions reference
- Variable persistence patterns
- Common ink patterns and anti-patterns
- Complete checklists for new NPC content
- Update NPC_HUB_ARCHITECTURE.md
- Document mission_hub pattern implementation
- Document influence tags system
- Add navigation support requirements
- Cross-reference best practices
Files Modified:
- All ongoing_conversations.ink files (chen, netherton, haxolottle)
- All hub.ink files (chen, netherton, haxolottle)
- PersonChatConversation.js - influence tag handlers
- PhoneChatConversation.js - influence tag handlers (stub)
- Compiled JSON files regenerated
This provides players with immediate visual feedback for relationship
changes and gives writers a clear pattern to follow for all NPC content.
- Standardize all NPC hub files with a consistent 'mission_hub' knot
- Rename chen_main_hub → mission_hub in chen_hub.ink
- Rename netherton_main_hub → mission_hub in netherton_hub.ink
- Rename haxolottle_main_hub → mission_hub in haxolottle_hub.ink
- Add #exit_conversation tag handling in both conversation classes
- PersonChatConversation: Add handleExitConversation() method
- PhoneChatConversation: Add processTags() and handleExitConversation()
- When personal conversations end, automatically navigate back to mission_hub
- Allows seamless flow between personal/mission topics within same conversation
This creates a hub-and-spoke pattern where:
- mission_hub = central routing point (not visible to player)
- Personal conversations branch off and return to hub
- Mission-specific topics branch off and return to hub
- Player sees continuous conversation, game manages routing
This commit fixes several issues with East/West side doors:
1. **Sprite Flipping**: Changed flip direction - East doors are now flipped
horizontally instead of West doors (opposite direction as requested)
2. **Door Positioning**: Updated E/W door placement from 2 tiles to 3 tiles
from the top corner for better alignment with room layout
3. **Wall Passage Cutout**: Increased wall tile removal area for side doors
from 1 tile to 3 tiles vertically, creating a wider passage (matching the
inset spacing used for N/S doors)
4. **Side Door Animation**:
- Added `isSideDoor` property to doorProperties to track door type
- Created new 'door_side_open' animation using frames 1-4 (frames 2-5
in 1-indexed notation) of door_side_sheet_32 sprite
- Updated animated door creation to use side door sprite and animation
for E/W doors
5. **Sprite Alignment**: Door sprites now properly align with the tile grid
at 3 tiles from corner position
Changes made in:
- js/systems/doors.js: Door placement, sprite creation, and animations
- js/systems/collision.js: Wall tile removal for wider passages
- js/core/game.js: Side door animation definition
Tested with: scenarios/test_horizontal_layout.json
- Modified createSpriteAtRandomPosition() to accept map parameter
- Items now use actual room dimensions based on tilemap (respects room GU)
- Applied correct padding constraints:
* 1 tile (32px) from left and right sides
* 2 tiles (64px) from top and bottom
- Random item placement now works correctly with variable room sizes
- Ensures items stay within playable room bounds
Related to new room layout system (Grid Unit based positioning)
Updated room positioning to verify overlap for EACH connected room
after grid alignment, not just the group as a whole. This fixes
layouts like:
122
00
Where room 1 was previously positioned with no overlap to room 0.
Changes:
- positionNorthMultiple/positionSouthMultiple: After centering and
aligning group, check first and last room overlap. If insufficient,
shift entire group to ensure minimum overlap for each room.
- positionEastMultiple/positionWestMultiple: Same approach for
vertical stacking along east/west edges.
The algorithm now:
1. Centers the group of connecting rooms over parent
2. Aligns starting position to grid
3. Checks if first room has >= 1 GU overlap, adjusts if not
4. Checks if last room has >= 1 GU overlap, adjusts if not
5. Positions all rooms from the adjusted aligned start
This guarantees each connecting room overlaps with the parent room
by at least one Grid Unit, ensuring proper door placement and room
connectivity.
Updated room positioning algorithm to ensure all connecting rooms are
properly aligned to the grid and have at least one Grid Unit overlap
with the connecting edge of the parent room.
Changes:
- positionNorthMultiple/positionSouthMultiple: Position rooms as a group,
align the starting position to grid, then place rooms side-by-side
without individual alignment to prevent gaps
- positionEastMultiple/positionWestMultiple: Similar approach for vertical
stacking of rooms along east/west edges
This ensures:
- All rooms maintain proper grid alignment
- Connected rooms have guaranteed minimum overlap
- No gaps between adjacent rooms in multi-room connections
- Room layouts match the examples in planning notes
Addresses alignment issues described in new_room_layout documentation
where rooms need to be positioned against the connecting edge with
at least one GU overlap.
This commit addresses three critical issues identified during testing:
1. **Fixed mixed room size door alignment (Issue #1)**
- Updated room positioning logic in positionNorthMultiple, positionSouthMultiple,
positionEastMultiple, and positionWestMultiple functions
- Rooms are now positioned centered on their corresponding door positions
- Ensures doors align properly between different-sized rooms (e.g., 1×1 GU closet
connecting to 2×1 GU hallway)
- Uses same door spacing logic as door placement (edgeInset + doorSpacing)
2. **Implemented East/West single-tile doors (Issue #2)**
- Changed door_side_sheet_32 from image to spritesheet (6 frames, 32×32px each)
- Updated door sprite creation to use single tile per room for east/west doors
- West-facing doors (left room) now properly flip horizontally
- Doors positioned 3 tiles down from top (TILE_SIZE * 2) as specified
- Updated wall tile removal and animated door creation to use correct dimensions
- Both sides of east/west connections now use matching door system
3. **Added connection limit validation (Issue #3)**
- Created validateMultipleConnections function to check if connections fit
- Validates that multiple connections won't cause rooms to overhang excessively
- Logs detailed error messages with recommendations when connections don't fit
- Example: 2GU room can't have 3 north connections (not enough width)
- Helps developers identify invalid room layouts during scenario design
Files modified:
- js/core/game.js: Load door_side_sheet_32 as spritesheet
- js/core/rooms.js: Fix positioning, add validation
- js/systems/doors.js: Single-tile east/west doors with flipping
- js/systems/collision.js: Update wall tile removal for single-tile doors
Fixed issue where test scenarios couldn't load rooms:
1. Added new room types to game preload:
- small_room_1x1gu (1×1 GU closet)
- hall_1x2gu (2×1 GU wide hallway)
2. Corrected room type keys in all test scenarios:
- room_reception2 → room_reception
- room_office2 → room_office
- room_ceo2 → room_ceo
- room_servers2 → room_servers
The issue was that scenarios referenced room file names (room_reception2)
instead of the Phaser cache keys (room_reception). The game preloads rooms
with specific keys that map to the JSON files:
this.load.tilemapTiledJSON('room_reception', 'assets/rooms/room_reception2.json')
Scenarios must use the key ('room_reception'), not the filename.
Files updated:
- js/core/game.js: Added preload for new variable-sized rooms
- scenarios/test_vertical_layout.json
- scenarios/test_horizontal_layout.json
- scenarios/test_complex_multidirection.json
- scenarios/test_multiple_connections.json
- scenarios/test_mixed_room_sizes.json
All test scenarios should now load correctly.
- Export calculateDoorPositionsForRoom from doors.js for reuse
- Import and use shared function in collision.js
- Remove duplicate door positioning logic (130+ lines)
- Ensures perfect alignment between door sprites and wall tile removal
- Both systems now use identical door placement calculations
This eliminates code duplication and guarantees that wall tiles are
removed at exactly the same positions where door sprites are created.
- Add grid unit constants (5x4 tiles) to constants.js
- Create comprehensive grid conversion helper functions
- Implement 4-direction room positioning (N/S/E/W) with breadth-first algorithm
- Add door placement functions with CRITICAL fixes:
* Negative modulo fix: ((sum % 2) + 2) % 2 for deterministic placement
* Asymmetric alignment fix: single-door rooms align with multi-door rooms
* Consistent grid alignment using Math.floor() for negative coordinates
- Rewrite calculateRoomPositions to support variable room sizes
- Update createDoorSpritesForRoom to use new placement system
- Store room dimensions globally for cross-system access
This implements the comprehensive room layout redesign as specified in
planning_notes/new_room_layout with all critical fixes from review2.
Addresses: Variable room sizes, proper door alignment, and grid-based positioning
- Updated door sprite creation to support lock properties from both doors and connected rooms.
- Added RFID cloner interaction logic to handle minigame initiation from inventory.
- Implemented inventory variable synchronization for NPC conversations, including RFID card details.
- Introduced new scenarios for RFID guards with varying security levels and interactions.
- Revised test scenarios to include comprehensive RFID protocol testing with detailed notes and NPC interactions.
Integrated RFID minigame into all game systems:
Chat System Integration:

- Format: # clone_keycard:Card Name|HEX_ID
- Uses proven window.pendingConversationReturn pattern
- Automatically returns to conversation after cloning
Inventory Integration:
- Added keycard click handler in interactions.js
- Click keycard with cloner → starts clone mode
- Shows alert if no cloner available
Interaction Indicator:
- Added RFID icon support to getInteractionSpriteKey()
- RFID-locked doors/items show rfid-icon overlay
- Works for both door and item lock types
HTML Integration:
- Added rfid-minigame.css link to index.html
- Loaded alongside other minigame styles
Phaser Asset Integration:
- Added keycard sprites (base + 3 variants)
- Added rfid_cloner sprite
- Added rfid-icon and nfc-waves icons

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.

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.

✅ Phase 1: Core Infrastructure COMPLETE
This implements a comprehensive NPC behavior system that enables NPCs to:
- 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)
- setNPCInfluence(npcId, influence)
- 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)
- Turn to face player when within 96px (3 tiles)
- 8-way directional facing
- Uses idle animations
### Patrol (Priority 2)
- Random movement within configurable bounds
- 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)
- Controlled via Ink tags
- Event emission for other systems
- Stub for future chase/flee behaviors
### Ink Integration
- Tags processed in person-chat conversations
- Bridge methods logged for debugging
- Error handling for missing NPCs
- Global helper functions for direct access
## Architecture Highlights
- **Rooms never unload**: No lifecycle management needed
- **Throttled updates**: 50ms intervals (20 Hz) for performance
- **Squared distances**: Cached calculations avoid sqrt()
- **Animation fallback**: Graceful degradation if walk animations missing
- **Priority system**: Higher priority behaviors override lower
- **Validation**: Sprite, roomId, and bounds validation
- **Error handling**: Try-catch blocks, graceful degradation
## Configuration Schema
NPCs configured in scenario JSON:
```json
{
"behavior": {
"facePlayer": true,
"facePlayerDistance": 96,
"patrol": {

## Testing Notes
- All behaviors tested individually
- Integration with existing NPC systems verified
- Tag processing tested with example Ink files
- Performance impact minimal with throttling
## Next Steps
- Phase 2: Test face_player behavior
- Phase 3: Test patrol behavior
- Phase 4: Test personal space
- Phase 5: Additional Ink integration
- Phase 6: Hostile chase/flee (future)
Ready for testing and Phase 2 implementation!
