What is a good way to check for colliders in a donut shape? My first thought was to use two Physics2D.OverlapCircle() and subtract the inner results from the outer results. But objects that overlap from the donut shape to the inner circle will be removed. In the example image the Green(A) and Yellow(B) colliders should be detected, while the Red(C) is discarded. Another way I can think of is to make this a PolygonCollider with a cutout, but that would change the thickness of the donut ring when it scales, it would be nice to have control over that. Any ideas?
