SphereCollider detects its own CharacterController?

Hi guys,

I am using a sphere collider on a gameobject with a character controller to represent my in-game enemies. I have a snippet of code that checks all gameobjects that enter the sphere and adds them to an array for a list of possible targets. See below:

	void OnTriggerEnter(Collider other){
		Debug.Log(other.name);
		for(int i = 0; i < 30; i++){
			if(targetList *== null){*

_ targetList = other.gameObject;_
* ChoosePrimaryTarget(); *
* return;*
* }*
* } *
* }*
my problem is, at runtime, it is adding 2 instances of itself to its target array. I’m not sure where these are coming from or why there are 2. Its only started happening since I added the character controller, so I know it has something to do with that. I just dont fully understand what is going on. I would think OnTriggerEnter would pull 1 at most. no other colliders are attached.
Thanks!

I believe the character controller already has a collider and a rigidbody. Therefore, your trigger is picking it up. You could put a tag on the controller and then change your code to:

void OnTriggerEnter(Collider other){
  Debug.Log(other.name);
  for(int i = 0; i < 30; i++){
    if(targetList *== null && other.tag != "controller"){ //for example*

targetList = other.gameObject;
ChoosePrimaryTarget();
return;
}
}
}
