Behavior trees are used by AAA studios to create lifelike AI, and with Opsive’s Behavior Designer you can bring that same proven approach to Unity.
Behavior Designer is a professional behavior tree system designed for programmers, designers, and artists alike. It combines an intuitive visual editor with a powerful and extensible API, allowing you to build complex AI logic that remains readable, maintainable, and easy to debug as your project grows.
With hundreds of built-in tasks, deep third-party integrations, and strong runtime tooling, Behavior Designer makes it possible to create sophisticated AI without requiring custom code while still providing full control when you need it.
Behavior Designer was built from the ground up with performance in mind. It allocates no memory after initialization and runs efficiently across all platforms, including mobile, making it well suited for both prototypes and shipped games.
