How to do it...

Just like decisions trees, we will create three pseudo-abstract classes for handling the process:

1. First, let's create the Task base class, as shown in the following code:

using UnityEngine; 
using System.Collections; 
using System.Collections.Generic; 
 
public class Task : MonoBehaviour 
{

    public List<Task> children; 
    protected bool result = false; 
    protected bool isFinished = false; 
} 

2. Next, we're going to implement the finalization function, as shown in the following code:

public virtual void SetResult(bool r) 
{ 
    result = r; 
    isFinished = true; 
} 

3. We then implement the function for creating behaviors, as follows:

public virtual IEnumerator Run() 
{ 
    SetResult(true); 
    yield break; 
} 

4. We then implement the general function for ...
