Parameters

other The other Collider involved in this collision.

Description

OnTriggerExit вызывается, когда Collider other перестает соприкасаться с триггером.

This message is sent to the trigger and the collider that touches the trigger. Notes: Trigger events are only sent if one of the colliders also has a rigidbody attached. Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

using System.Collections;

public class ExampleClass : MonoBehaviour { void OnTriggerExit(Collider other) { Destroy(other.gameObject); } }

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