Behave is a solution for designing, integrating and running AI behaviour logic using behaviour trees. At its core Behave has a drag-drop designer and a highly effective and flexible compiled runtime.
No funky runtime data formats or interpretation. Designer → Compiler → Your code.
- Unobstructed design process - designer is not blocked by developers not having implemented needed actions.
- Flexible, non-limiting integration - no heavy API requring you to jump through hoops to integrate with your code.
Completing the circle of tools and runtime, Behave ships with a powerful debugger runtime and UI with the following feature set:
- Seamless integration – just build for debug.
- Live visualisation of tree state as running in the Unity editor or on your target device.
- Full support for execution break, step and reset within a running simulation.
- Action return value overrides for scenario testing and working with yet unimplemented actions.
The default Behave package lets you use the designer inside the Unity editor and compile your Behave libraries to the Unity .net runtime. Should you so desire, other compilers and a stand-alone editor is available on alternative licenses.
