Behavior trees are used by AAA studios to create a lifelike AI. With Opsive's Behavior Designer, you can bring the power of behaviour trees to Unity!

Behavior Designer is a behaviour tree implementation designed for everyone - programmers, artists, designers.

Behavior Designer offers an intuitive visual editor with a powerful API allowing you to easily create new tasks. It also includes hundreds of tasks, PlayMaker integration, and extensive third party integration making it possible to

create complex AIs without having to write a single line of code!

Behavior Designer was designed from the ground up to be as efficient as possible with zero allocations after initialization. As a result, it runs great on all platforms including mobile.
