Reply To: Multiple Behaviour Trees

[Gavalakis]

Hello and welcome 🙂

A single BehaviourTreeOwner is needed regardless of the number of BehaviourTrees you are going to run with it.
Think of it like the Animation component from which you can run any number of different AnimationClips.
The BehaviourTreeOwner has a SwitchBehaviour method to switch between different BehaviourTrees at runtime.
Here is an example:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31

using UnityEngine; using NodeCanvas.BehaviourTrees; public class Example : MonoBehaviour {     public BehaviourTree idleBehaviour;     public BehaviourTree fleeBehaviour;     public BehaviourTree attackBehaviour;     private BehaviourTreeOwner agent;     void Start(){         agent = GetComponent<BehaviourTreeOwner>();         agent.StartBehaviour(idleBehaviour);     }     void Update(){         if (Input.GetKeyDown(KeyCode.Alpha1))             agent.SwitchBehaviour(idleBehaviour);         if (Input.GetKeyDown(KeyCode.Alpha2))             agent.SwitchBehaviour(fleeBehaviour);         if (Input.GetKeyDown(KeyCode.Alpha3))             agent.SwithBehaviour(attackBehaviour);     } }

Let me know if that’s what you are after 🙂
