void OnCollisionEnter

i can't get this collision detection to work, heres my script:

Code (csharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class movement : MonoBehaviour {
5.     public int accSpeed;
6.     public Vector3 force;
7.     private Vector3 spawn;
8.     public GameObject die;
9.     void Start (){
10.         spawn = transform.position;
11.         }
12.     void Update () {
13.         force = new Vector3 (Input.GetAxis ("Horizontal"), 0, Input.GetAxis ("Vertical"));
14.         rigidbody.AddForce (force * accSpeed);
15.     }
16.     void OnCollisionStay(Collision other){
17.         if (other.transform.tag == "enemy") {
18.                         Instantiate (die, transform.position, Quaternion.identity);
19.                         transform.position = spawn;
20.                 }
21.     }
22. }
23.  

/edit i just noticed im using OnCollisionStay but it dosnt work wit either
/edit2 more info

I have read that the collider sometimes needs a rigid body which i have, and has the isKinnematic trigger on. I dont want IsTrigger because then it wont collide.

 

Script seems to be working, make sure you set the correct tag and check for typos (case sensitive)..

 

i know, enemy is spelt lowercase forgot to add to op
