Task Node

Type description and basic instructions.

Description

Task Node is base abstract class for all task nodes.

To create a custom task node you should inherit from Task Node class and implement logic that is described below.

OnUpdate

When inheriting from Task Node you have to override OnUpdate method.

public class ExampleTaskNode : TaskNode
{
    protected override State OnUpdate() 
    { 
        throw new System.NotImplementedException();
    }
}

• OnUpdate gets called every tick during node execution according to Behaviour Tree Update Mode.

• OnUpdate returns state of the node after update.

OnEnter and OnExit

You can also override OnEntry and OnExit methods.

public class ExampleTaskNode : TaskNode
{
    protected override void OnEntry()
    {
        base.OnEntry();
    }
 
    protected override State OnUpdate() 
    { 
        throw new System.NotImplementedException();
    }
    
    protected override void OnExit()
    {
        base.OnExit();
    }
}

• OnEntry gets called when Behaviour Tree enters the node.
• OnExit gets called when Behaviour Tree exits the node.

To create custom task nodes in editor you should add Node Content attribute to your custom task node class.
