Question by Hjalte · Aug 06, 2014 at 11:02 PM · c#triggernavmeshontriggerentertriggers

OnTriggerEnter doesnt see enemy

I have a very simple script that prints a message when a gameobject with a certain tag enters a triggercollider. And the thing is that when the enemy enters nothing happens but when the player walks in it works just fine. Heres the script:

     void OnTriggerEnter (Collider other) {
         if (other.gameObject.tag == "Enemy") {
             print("Enemy");    
         }
         if (other.gameObject.tag == "Player") {
             print("Player");    
         }
     }

The enemy is using the nav mesh agent with some simple code to make it follow the player. Heres that code:

     private NavMeshAgent agent;
     public Vector3 playerPos;
     public GameObject player;
 
     void Start() {
         agent = GetComponent<NavMeshAgent>();
     }
     void Update() {
         playerPos = player.transform.position;
         agent.SetDestination(playerPos);
     }

First thing I'd do to troubleshoot is to make sure that OnTriggerEnter is or isn't being called in the first place. $$anonymous$$aybe you're missing a component, or a component is present but configured incorrectly.

Does the enemy have a rigid body on it? If the collider that checks for collisions doesn't have a rigid body, and the player does, it will register the player, but if the enemy doesn't have a rigid body, they dont recognize the collision.
