MonoBehaviour.OnTriggerExit

function OnTriggerExit (other : Collider) : void

Description

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 rigid body attached.

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

OnTriggerExit can be a co-routine, simply use the yield statement in the function.
