Question by FatalNightmare · Nov 17, 2013 at 12:27 AM · javascriptfunctiononcollisionenter

OnCollisionEnter does not work.

Hey guys I am trying to make it so that once my AI hits an interactive object(couch) then he switches to another waypoint, but nothing happens when my AI hits an object, the function is not being called cause I put a debug right at the beginning. I have the couch tagged as "Interactive" and placed this code on the AI. NOTE: this is a long script, I have set currentWaypoint and randomWaypointRange as ints FYI.

 function OnCollisionEnter(other : Collision){
  if(other.gameObject.tag == "Interactive"){
  Debug.Log("Hit an Object");
 currentWaypoint = Random.Range(0,randomWaypointRange); 
  
  
  }
  }

Are you even entering the OnCollisionEnter method ? Pu a Debug.Log line before the "if" statement to be sure of that.

No, I put the Debug.Log before the "if" and it didn't show the message.

So the problem is not related with tags (or maybe but we'll see that later ...).

Do you have any collider type attached to the game object that contains this script ?

I have a CharacterCollider and rigidbody

Ok, and do the other game objects, tagged "Interactive" contain a rigidbody or a collider too ?

View the bottom of this reference page and make sure the two colliders you want to collide are compatible.

Collider Reference

Then once they are colliding correctly make sure that the gameObject is tagged correctly.
