Question by Swordslam46 · Mar 10, 2013 at 03:12 AM · collision

Bullets Not Deleted Upon Collision

Hello, I'm new to Unity, but not to coding. I recently tried making a script that will delete bullets upon collision, but it doesn't work.

 function OnCollisionEnter(collision : Collision)
 {
     if(collision.gameObject.tag == "Ammo")
     {
         Destroy(collision.gameObject);
     }
 }

any help would be appreciated.

Attach the debugger and step through the code to find the issue.

Is the OnCollisionEnter callback being called? Does the if-statement evaluate to true? If not, why so?

Destroy surely works, but perhaps your bullet game object has a child object with the collider. In that case you'd destroy the game object with the collider but not the parent game object, but I doubt you've set it up like this.

$$anonymous$$oreover @Swordslam46, have you remembered to tag the object "Ammo"? Happens a lot believe me ...

Yes, the tag is not the name nor the layer of the object.
