Explosion that kills enemy.

I have and enemy set up with an enemy health script, like this

var health = 1.0;
var hitsound : AudioClip;

function OnTriggerEnter (hit : Collider) {
	if (hit.gameObject.tag == "cube") {
		
		health -= 1;
		
		if (hitsound)
			AudioSource.PlayClipAtPoint(hitsound, transform.position);	
	}
}

function Update () {
	if (health == 0) {
		Destroy (gameObject);
		
		if (hitsound)
			AudioSource.PlayClipAtPoint(hitsound, transform.position);	
	}
}

and I need to have an explosion cause damage to the enemy. I would like to keep my current system, unless I absolutely cant achieve what I need with the way I have it set up. I am using the detonator package, with the chunks pre made explosion, and I need the explosion to cause damage, not the projectile (I’m using a grenade, and so that wont work that way)

Use “if hit.gameObject.tag == “Explosion”” instead of cube and have your grenades create short-lived trigger zones that are tagged Explosion (or whatever).
