Reply To: Instantiate Behavior Tree

[GavalakisKeymaster]

Hello there,

As the log states, the BehaviourTree asset, needs to be instantiated before usage.
So what you can basically do is this:

1 2 3 4 5 6

var dialogueMapperAsset = Resource.Load<BehaviourTree>("DialogueMappers/" + NPCName); var dialogueMapperInstance = Instantiate<BehaviourTree>(dialogueMapperAsset); dialogueMapperInstance.StartGraph(agent, blackboard, true, (bool obj) => { EndAction(obj); } ); //Remember to destroy the instance when no longer needed.

While the above will work, if you want to bind the asset to a gameobject more permanently, you can do something like this:

1 2 3 4

var owner = go.AddComponent<BehaviourTreeOwner>(); owner.StartGraph( dialogueMapperAsset ); //this will assign and start the graph

Let me know if the above work for you 🙂
Thanks.
