How to check all the gameobjects inside a circle collider 2D trigger?

I want to get all the gameobjects who is inside the circle collider and give them health. It totally doesn't work at all, not even the debug.log work. My Player works though. I am just hard coding everything right now.

This collider is a spell. Once is activated, this turns on:


private void OnTriggerEnter2D(Collider2D collision)

Code (CSharp):

1.     private void OnTriggerEnter2D(Collider2D collision)
2.     {
3.         if (collision.CompareTag("Ally"))
4.         {
5.             Character c = collision.GetComponentInParent<Character>();
6.             c.Healing(50, source);
7.  
8.             Debug.Log("hit");
9.         }
10.     }

 

actually i got it to work with triggerstay
