Is possible to create by code a BT, FSM or DT?

For example to create an script, that runs some instructions like:
State node = new StateNode();
Task task = new Task(WaitUntil);
node.addTast(task);

Is there an api and/or samples of the that?

thanks in advance

Hello,

Yes, that is quite possible. Here is an example of creating a Behaviour Tree:

using UnityEngine;

using NodeCanvas.Framework;

using NodeCanvas.BehaviourTrees;

using NodeCanvas.Tasks.Actions;

public class CreateBTInCode : MonoBehaviour {

void Awake(){

var owner = GetComponent<BehaviourTreeOwner>();

if (owner == null){

return;

}

var bt = ScriptableObject.CreateInstance<BehaviourTree>();

var seqNode = bt.AddNode<Sequencer>(new Vector2(5000, 5000));

var actNode1 = bt.AddNode<ActionNode>(seqNode.nodePosition + new Vector2(-100, 100));

var actTask1 = (Wait)Task.Create(typeof(Wait), bt);

actNode1.task = actTask1;

var actNode2 = bt.AddNode<ActionNode>(seqNode.nodePosition + new Vector2(100, 100));

var actTask2 = (Wait)Task.Create(typeof(Wait), bt);

actNode2.task = actTask2;

bt.ConnectNodes(seqNode, actNode1);

bt.ConnectNodes(seqNode, actNode2);

owner.behaviour = bt;

}

I will create some more similar examples and add a new section in the documentation.
Meanwhile, if you have any questions on this, just let me know.

Thanks
