Gameobject not destroyed OnCollisionEnter

Question

I have this GameObject with the tag coin I am trying to destroy when the player collides with it using this code located in a player script attached to the player

    public void OnCollisionEnter(Collision col){
        var hit = col.gameObject;
        if(hit.tag == "Coin"){
            Destroy(hit.gameObject);
        }
    }

However upon collision nothing is happening

Answer 1

First you must check:

1. collider => IsTrigger =>false
2. Rigidbody => IsKinematic =>false
3. you mentioned 3d so check their gameObjects z position
4. finally you check your tag name into corresponding to their gameobject

Answer 2

I figured out the issue the problem was in order to use OnCollisionEnter at least one of the objects must have a rigidbody component attached

Answer 3

Few things you have to keep in mind.

• Rigidbody must attached to either Gameobject
• Make sure that your script attached to the GameObject is not isTrigger checked.
• Verify if the OnCollisionEnter is being executed, by breakpoints or logs.
• Make sure the tag of other GameObject (col.gameObject)
• And you don't need to destroy hit.gameObject as hit is already a GameObject.

You can do it like

void OnCollisionEnter(Collision col){

    var hit = col.gameObject;

    Debug.Log("In collision enter");

    if(hit.tag == "Coin"){
        Debug.Log("In destroy check");
        Destroy(hit);
    }
}
