Considering I understood correctly, this is actually pretty easy to do 🙂
The BehaviourTreeOwner (or any GraphOwner for that matter), has a “StartBehaviour” overload that takes a System.Action<bool> argument as a callback. As such, when (for any reason, even by the included ControlGraphOwner action task) the behaviour is stopped, the callback will be called. For example:
1
2
3
4
5
6
7
8
9
10
voidExample(){
varowner=GetComponent<BehaviourTreeOwner>();
owner.StartBehaviour(OnStop);
}
voidOnStop(boolsuccess){
Debug.Log("The behaviour has stopped");
}
Thus the “trick” here, is simply to provide a callback when the behaviour starts. Ending the behaviour can be done in any way and the callback will still be called.
