Unity Colliders - How do I detect nearby objects without my detection ranges detecting each other

Question

How can I get both colliders' types in a trigger overlap message like OnTriggerExit2D(Collider2D other)?

Example:

• objects A and B both have a BoxCollider2D and CircleCollider2D components.

• Then, object A enters one of the trigger colliders of object B.

• I can get object B's collider type with the is operator.

How can I get A's collider type?

The reason I want this is that I want only collisions where object A's CircleCollider2D touches object B's BoxCollider2D.

void OnTriggerExit2D(Collider2D other)
{
    if (other is BoxCollider2D)
        //Do Code
}

Here is a table of what I want: I want only to register trigger overlaps from CircleCollider2D to BoxCollider2D. With the is operator, I can safely remove all collisions to CircleCollider2D but collisions between two BoxCollider2D stay, which I do not want.

+------------------+---------------+------------------+
|  Row to Column   | BoxCollider2D | CircleCollider2D | 
+------------------+---------------+------------------+
| BoxCollider2D    | No            | No               | 
| CircleCollider2D | Yes           | No               | 
+------------------+---------------+------------------+

Edit The real questions was to detect nearby objects without the detection range dectecting each other.

Answer 1

With Physics2D.OverlapCircleNonAlloc, you can set an area around a point (my gameobject) and then saving the results in a Collider2D[] array which contains all objects nearby from the range I want.
