OnTriggerExit is called when the Collider other has stopped touching the trigger.

This message is sent to the trigger and the collider that touches the trigger. Note that trigger events are only sent if one of the colliders also has a rigidbody attached.

	// Destroy everything that leaves the trigger
	function OnTriggerExit (other : Collider) {
		Destroy(other.gameObject);
	}

    void OnTriggerExit(Collider other) {
        Destroy(other.gameObject);
    }
}

	def OnTriggerExit(other as Collider) as void:
		Destroy(other.gameObject)
