Object Destroyed while inside Trigger not causing exit signal

I have found that I have a case in which my trigger is not realising that it no longer has an occupant collider. I have an OnTriggerStay and OnTriggerExit function, however , in the case when an object is being destroyed while inside the trigger box, it is not registering as an exit. How exactly would I go about checking to see if it exists or not?

 

Hi @richardzzzarnold,

You can create a temporary collider around the object and then check for the objects that you search... Then you can run any function you like. You can use it as a bool. If there's no object that you search for, then you can do something...

Code (CSharp):

1. using UnityEngine;
2.  
3. public class MyScript : MonoBehaviour
4. {
5.     public float radius;
6.  
7.     private void MyCode()
8.     {
9.         Collider[] colliders = Physics.OverlapSphere(transform.position, radius);
10.  
11.         foreach (Collider col in colliders)
12.         {
13.             if (col.gameObject.tag == "Enemy") //search for tag...
14.             {
15.                 Destroy(col.gameObject);
16.             }
17.  
18.             if (col.gameObject.layer == LayerMask.NameToLayer("Enemy")) //search for layer...
19.             {
20.                 Destroy(col.gameObject);
21.             }
22.         }
23.     }
24. }
25.  

 

If there are not any objects with Enemy layer then do something...

Code (CSharp):

1. if (!Physics.OverlapSphere(transform.position, radius, LayerMask.GetMask("Enemy")))
2.     {
3.       //Do Something...
4.     }
