GetRelativePoint, GetRelativeVector doesn't work.

Hello, for some reason those 2 functions don't work on my rigidbody2D of a rocket.

They always return 0,0.

This is my code

 #pragma strict
 var rocket : GameObject; //Prefab
 function Start () {
 
 }
 
 function Update () {
 
 }
 
 function OnTriggerEnter2D(obj : Collider2D){
     if(obj.name == this.name){ //If rocket goes into a no-no zone, I want to destroy it and spawn some more rockets going into another direction.
         spawnRockets(obj.gameObject);
         //Debug.Log(rocket.rigidbody2D.GetRelativePoint(Vector2(0.01,0.01))); //The Rocket is correct, just get relative point doesn't work.
         Destroy(gameObject); //Works
         Destroy(obj.gameObject); //Works
     }
 }
 
 function spawnRockets(obj : GameObject){
     //0 Degrees
     var a = Instantiate(rocket, gameObject.transform.position , Quaternion.identity); //Creates another rocket.
     a.GetComponent(Rocket).destination = rocket.rigidbody2D.GetPoint(Vector2(100,100)); //Works, but since the GetPoint returns 0,0 it doesn't work correctly.
     Debug.Log(obj.name); //Gets the correct name, I give all my rockets a unique name.
     Debug.Log(a.rigidbody2D.GetRelativeVector(Vector2(0.01,0.01))); //Doesn't work no matter how I spin it. Returns 0,0
 }

Anyone know what the problem might be?
