Making Enemy Retreat

Question

Hello! I'm trying to make an enemy retreat after so many seconds after it's spawned. I tested out the transform.position and the enemy moves straight towards, so I know that part works. However, when I tried to make the time delay happen by using invoke() code and putting the transform code in a custom function, the enemy remains where it was spawned.

  #pragma strict
     
     public var enemyspeed : float; //how fast enemy goes
     private var retreatPoint: Vector3; //holds the coordinates to the retreat point
     private var step : float; //speed *frames value
     
     function Awake () {
         // sets speed of enemy
         var step = enemyspeed * Time.deltaTime;
     }
     
     function Start () {
 //after 4 seconds, bunyip retreats
         Invoke ("BunyipRetreat", 4);
     }
     
     function Update () {
         //coordinates for retreatingpoint
             retreatPoint = Vector3(24,0,20);
         
     }
 
 //custom function
     function BunyipRetreat() {
 //moves bunyip to retreating point
         transform.position = Vector3.MoveTowards(transform.position,retreatPoint,step);
     }

I think MoveTowards needs to be in the Update function. Try this.

  #pragma strict
      
      public var enemyspeed : float; //how fast enemy goes
      private var retreatPoint: Vector3; //holds the coordinates to the retreat point
      private var step : float; //speed *frames value
      public var retreating : bool; //A trigger to see if retreating is true
      
      function Awake () {
          // sets speed of enemy
          var step = enemyspeed * Time.deltaTime;
      }
      
      function Start () {
  //after 4 seconds, bunyip retreats
          Invoke ("BunyipRetreat", 4);
      }
      
      function Update () {
          //coordinates for retreatingpoint
              retreatPoint = Vector3(24,0,20);
          if(retreating){
                   transform.position = Vector3.MoveTowards(transform.position,retreatPoint,step);
          }
      }
  
  //custom function
      function BunyipRetreat() {
      retreating = true;
 
      }

Note* I do not use UnityScript/JavaScript, so that might be broken terribly. But, I hope it gives you an idea of what you need to do.
