Making Enemy Retreat

Questions & Answers
1

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.
