Input.GetKeyDown(KeyCode.E) not working?

Question

C++ / C#

I'm learning to create games, but I can't make one of the mechanics. If I remove "&& Input.GetKeyDown(KeyCode.E)", then when colliding with a friend, the player's prefab is deleted, as soon as I add it, nothing happens.

private void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.tag == "Friend" && Input.GetKeyDown(KeyCode.E))
        {
            Destroy(gameObject);
        }
    }

Answer 1

Inputonly needs to be calledUpdate
