MonoBehaviour.OnTriggerExit(Collider)

Parameters

Description

OnTriggerExit is called when a collider stops touching a trigger.

OnTriggerExit is called during whichever iteration of the physics FixedUpdate loop Unity detects that a collider is no longer touching a trigger it was previously touching.

Both GameObjects must contain a Collider component. At least one of the colliders must be a trigger collider and at least one must be a physics body collider. For more information, refer to OnTrigger events.

Trigger events are sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions. Deactivating or destroying a collider while it is inside a trigger volume does not cause an OnTriggerExit message to be sent.

Both the trigger and the collider that touches the trigger receive OnTriggerEnter if they have implemented it.

OnTriggerExit can be a coroutine.

// Destroy everything that leaves the trigger

using UnityEngine;
using System.Collections;

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