Custom Behavior Tree Actions

[Other-JeffParticipant]

OKay,

My next task is to create a number of behavior tree actions to trigger MOB actions like “attack”.

I assume I inherit from BTActionNode. What else do I need to do to make the editor and system aware of my new action?

I gave the class a [RAINAction] property but that didnt seem to help

You can create your own Action by selecting “Create Custom Action” while having a Custom Action Node selected.

Use public Expression fields to display Expressions in the inspector.

Simple example:

using RAIN.Representation;
using UnityEngine;
using RAIN.Action;
namespace LordsAndLegends.AI.Actions
{
    [RAINAction]
    public class DebugLog : RAINAction
    {
        public Expression Message = new Expression();
        public override ActionResult Execute(RAIN.Core.AI ai)
        {
            Debug.Log(Message.ToString());
            return ActionResult.SUCCESS;
        }
    }
}

The RAINAction class provides several virtual methods you can override.

Thanks, saw that just last night. I wish the tree would show them individually rather then just as generi “action” where you have to inspect it to see what it is…

[Other-JeffParticipant]

Is there a way for me to show the name in the behavior tree of the custom action? The wiki looks like there is but it doesnt explain how?

[Other-JeffParticipant]

Okay i found the name field… but having to set it for each node is ugly
