Pathfinding & NPC AI Framework

A powerful NPC AI framework for Roblox built on top of PathfindingService with significant enhancements. Create enemies, companions, and ambient NPCs with complex behaviors using a simple state machine API.

Pathfinding Enhancements

• Dynamic Obstacle Avoidance: NPCs recompute paths when obstacles appear. Handles moving obstacles.
• Path Smoothing: Bezier curve smoothing for natural-looking movement.
• Jump & Climb: NPCs can jump over gaps and climb ladders/ropes.
• Group Pathfinding: Multiple NPCs navigate together without clumping.

Behavior System

• State Machine: Define NPC states (Idle, Patrol, Chase, Attack, Flee, Interact) with transition conditions.
• Behavior Trees: Compose complex behaviors from simple nodes (Sequence, Selector, Condition, Action).
• Perception System: Sight cone, hearing radius, and memory. NPCs remember last known player position.
• Preset Archetypes: Guard, Patrol Enemy, Aggressive Enemy, Passive NPC, Companion — ready to use.

Performance

Uses a priority queue for path requests. Configurable max concurrent pathfinding operations. Tested with 50 active NPCs at 60fps server-side.
