Delete on collision detection. Deletes the collider component rather than the prefab

So I want a ring to be deleted once it's been touched by the player. I noticed that the BoxCollider that I have as a component for the ring deletes. Instead of the entire ring. I want the whole ring to delete. How can I do this? Assuming from Lua, can I get the parent or something? Any other method would be great also.


#pragma strict

function OnTriggerEnter(col : Collider){
if(col.gameObject.tag == "Ring"){
print("isring");
Destroy(col);
}
}

 

Instead of "Destroy(col)" do "Destroy(col.gameObject)"
