NPC spawns in `startRoom` + - System validates all route rooms exist + - System validates all room connections exist (doors) + - All route rooms are pre-loaded + +2. **Waypoint Patrol** + - NPC follows waypoints in order (sequential mode) or randomly + - At each waypoint, NPC pauses for `dwellTime` (if specified) + - NPC uses pathfinding to navigate between waypoints + +3. **Room Transition** + - When current room's waypoints are complete, NPC transitions to next room + - System finds door connecting the two rooms + - NPC sprite is relocated to the new room at the door position + - NPC's `roomId` is updated in the NPC manager + - Waypoint patrol continues in new room + +4. **Loop** + -

The system finds the door connecting rooms and positions the NPC at that door when transitioning. + +**Q: What happens if rooms aren't connected?** +A: The route validation will fail and multi-room is disabled for that NPC. The NPC falls back to random patrol in its starting room. + +**Q: Can NPCs have different movement speeds in different rooms?** +A: Currently, speed is global. All rooms use the same `patrol.speed`. This can be enhanced in future versions. + +**Q: What if an NPC gets stuck?** +A: If a waypoint is unreachable, the NPC tries the next waypoint or transitions to the next room. The system has automatic fallback behavior. + +**Q: Can I pause or modify routes during gameplay?** +A: Currently no, routes are fixed after initialization. Dynamic route changes can be added in future versions. + +## Related Documentation + +- See `NPC_PATROL.md` for single-room waypoint details +- See `NPC_INTEGRATION_GUIDE.md` for NPC setup overview +- See `GLOBAL_VARIABLES.md` for NPC manager details diff --git a/js/core/rooms.js b/js/core/rooms.js index fd5341d..c3a0a65 100644 --- a/js/core/rooms.js +++ b/js/core/rooms.js @@ -1499,6 +1499,19 @@ export function createRoom(roomId, roomData, position) { } rooms[roomId].objects[sprite.objectId] = sprite;
