Object with no collider

Object with no collider

As you may know from the title, I want to test if a object without a Cube Collider is overlapping an object (a First Person Controller). And if it is true, I want it to take 1 off of a variable. Here is the Script I have already:-

var healthtext : GUIText;
var health = 100;

function Update(){
	healthtext.text = health.ToString();
	
	if(What goes here){
		var health = health-1;
		yield WaitForSeconds(1);
	}
}

Any answers are appreciated

Thanks for the answer. I cannot turn robertbu’s comment into an answer but here is what my code is now…

var healthtext : GUIText;
var health = 100;
var player : GameObject;

function Update(){
	healthtext.text = health.ToString();
	
	if(this.renderer.bounds.Contains(player.transform.position)){
		health=health-1;
	}
}

Thanks!
