BTGraph

BT Graph is a lightweight Behavior Tree system for Unity that combines a visual graph editor with a robust runtime engine. It allows you to design, debug, and reuse AI logic as data-driven assets instead of hard-coded scripts.

With BT Graph, you can quickly prototype behaviors, scale them to complex agents, and keep your gameplay logic readable and maintainable. The built-in Blackboard system enables clean data sharing and runtime binding, while the editor focuses on speed, clarity, and minimal friction.

Whether you’re building simple NPC movement or more advanced decision-making systems, BT Graph helps you iterate faster, stay organized, and keep control over how your AI behaves—without heavyweight frameworks or boilerplate code.
