Colliding ONLY with objects with a tag

Unity Engine
1

The title explains it.
here is my script so far.

function OnTriggerEnter (other : Collider) {
orbsLeft.orbsFound += 1;
}

its not adding 1 every time i hit the bead, which has the tag.
instead, its adding 1 half of the time i hit the wall or ledge.
thanks:p

Try:

function OnTriggerEnter (other : Collider) {
    if(other.CompareTag("tag")){
        orbsLeft.orbsFound += 1;
    }
}

i think the problem is because OnTriggerEnter OnTriggerStay OnTriggerExit acts only when u enter inside the collider and not when it hits, so u must use a collider with “IsTrigger” checked true.

otherwise, You should use “OnControllerColliderHit” on the controller object :

function OnControllerColliderHit (hit : ControllerColliderHit) {
	// when it hits an objects with a tag "old_paper" 
	if (hit.gameObject.tag == "old_paper"){ 
		Destroy(hit.gameObject);
                caracter_item.Add("old_paper");
		audio.PlayOneShot(pick_item_1);
	}
}
