Adding OnCollisionEnter to instantiated object not working properly!

Hello,

Basically I am instantiating an object in a 2D game and adding a On Collision Enter script to it. However it is not triggering for some reason. Both objects have a Rigidbody2D component and a box collider

Script 1:

.......

 GameObject firedArrow =(GameObject) Instantiate (Arrow, firePointPosition, Quaternion.FromToRotation(Vector3.right,firePointPosition));
         firedArrow.AddComponent<ArrowDamageScript> ();
         if (playermiddleposition.x - firePointPosition.x >= 0) {
             speed = -speed;
             firedArrow.GetComponent<Rigidbody2D> ().velocity = new Vector2 (speed, 0f);
             speed = -speed;
         } else {
             firedArrow.GetComponent<Rigidbody2D> ().velocity = new Vector2 (speed, 0f);
         }
 ........

Script 2:

 void Start(){
         Debug.Log ("Script added!");
     }
     void OnCollisionEnter(Collision col) {
         ContactPoint  contpoint = col.contacts[0];
         Debug.Log ("We hit " + col.collider.name + " and did " + Damage + " damage.");
         
         Destroy (col.gameObject);
     }

I do get the debug message that the script was added. However, nothing is happening upon collision. Any ideas?

dude if it's a 2d game you should change

  void OnCollisionEnter(Collision col) {
      ContactPoint  contpoint = col.contacts[0];
      Debug.Log ("We hit " + col.collider.name + " and did " + Damage + " damage.");
      
      Destroy (col.gameObject);
  }

  void OnCollisionEnter2D(Collision2D col) {
      ContactPoint  contpoint = col.contacts[0];
      Debug.Log ("We hit " + col.collider.name + " and did " + Damage + " damage.");
      
      Destroy (col.gameObject);
  }

also you have to attach a boxCollider2D to your object ,not boxCollider
