Delete boxcollider2D(Trigger)

Fixed it without the Int, was a bad idea. Here the solution for people with the same ideas/problems:

(First I clicked: break Prefab Instance, to make them seperate)

Script Poles:

private void OnTriggerEnter2D(Collider2D collision) {

     if (collision.gameObject.tag == ("Player"))
     {
         Destroy(gameObject.GetComponent<BoxCollider2D>());
     }

 }

Script Player:

Vector3 polePos;

private void OnTriggerEnter2D(Collider2D collision) {

     if (collision.gameObject.tag == "Pole")

     {
        polePos = new Vector3 (transform.position.x, transform.position.y, transform.position.z);
     }

private void OnCollisionEnter2D(Collision2D collision) {

     if (collision.gameObject.tag == "died")

     {
        transform.position = polePos;
     }
