Why does this script not do anything?

Code (JavaScript):

1. #pragma strict
2.  
3. var deadScene : String;
4.  
5. function Start () {
6.  
7. }
8.  
9. function Update () {
10.  
11. }
12.  
13. function OnCollisionEnter(other : Collision) {
14.     if(other.gameObject.tag == "Player") {
15.         Application.LoadLevel(deadScene);
16.     }
17. }

 

Do you have two colliders, one with at least a rigidbody, on your two objects? If you have a mesh collider it might need the convex option checked.
