How to check if game object is destroyed?

Questions & Answers

My OnTriggerExit2D is being called even though the collider has been destroyed. I’d like a way to check whether the colliding object has been destroyed or not. Is there any way to do this short of adding a bool to my colliding object?

Code:

        private void OnTriggerEnter2D(Collider2D collision)
        {
            Destroy(collision.gameObject);
        }
    
    
        private void OnTriggerExit2D(Collider2D collision)
        {
            // collision.gameObject != null -- Doesn't work
            // collision.gameObject.activeSelf -- Doesn't work
            Debug.Log("OnTriggerExit2D is being triggered on a destroy");
        }

I think this was answered in https://forum.unity.com/threads/does-ontriggerexit2d-activate-when-an-object-is-destroyed.499161/.

Essentially, doesn’t work, you need to find another way to cope with destroying objects. For my context, I think I’ll simply add a feature to “disable” the game objects and destroy them only when off screen.
