Behavior tree shared by various prefabs?

[edamiani]

Hi, I have a series of prefab characters that should share the same behavior tree, but despite my efforts I couldn’t find a way of centralizing the behavior tree in a way that I would edit one of its instances and automatically replicate the changes to the behavior tree inserted in the remaining prefabs.

My question is: is it possible at all? I tried to transform the behavior tree in a prefab and add it to the character prefabs, but it seems that the connection to the BT prefab is lost once I apply the character’s prefab (besides, the blackboard isn’t available that way, so I guess this is the wrong way of doing it, nevertheless).

I’m using NodeCanvas 1.6.1.

Thanks and best regards,
Edgard

Hello Edgard,

Is there a reason you don’t upgrade to version 2? 🙂

Regarding you question, I just tried this and works:

– Create a prefab BehaviourTree.
– Create a prefab BehaviourTreeOwner gameobject.
– Assign the prefab BT to the prefab BTOwner.
– Add the prefab BTOwner in the scene.
– Hit Apply on the instance.

The reference to the prefab BT graph is not lost.
Can you confirm?

Cheers!
