Whether you're making friendly NPCs wandering a field, Enemy Soliders patrolling a tightly packed city, Armies for the player to control, or any other classical AI logic simple or complex Behavior Tools For Unity is the tool for you!
Behavior Tools for Unity is built on top of Unity's own free visual behavior tree authoring system Behavior Graph (The Behavior Package in the Unity Registry) but with an additional 200 low level ready to use nodes which you can combine to make anything from the simplest to most complex behaviors , 15 conditions to alter the flow of your trees, and gizmos that automatically sync with variables in your agent's blackboard. Designing NPC behaviors without ever having to touch the underlying code has never been easier!
Feature Overview
- Full support for both 2D and 3D Phyiscs, Navigation, and everything else you need to create to create NPC agents for either type of game.
- Over 200 Action Nodes that can be used to control your NPC agent behaviors ranging from simple math calculations to complex navigation logic.
- Over 15 Conditions that can be used to alter the flow of agent decision making.
- 9 Different Gizmos that can automatically synced their values with variables on your agent's visual behavior graph.
- 3 Simple Demo Scenes Showing some of the basics of creating Behavior Graphs (though much more complex logic is just as possible out of the box)
