| layerMask | Filter to detect Colliders only on certain layers. |

RaycastHit2D The cast results returned.
Casts a circle against colliders in the scene, returning the first collider to contact with it.
A CircleCast is conceptually like dragging a circle through the scene in a particular direction. Any object making contact with the box can be detected and reported.
This function returns a RaycastHit2D object with a reference to the collider that is hit by the box (the collider property of the result will be NULL if nothing was hit). The layerMask can be used to detect objects selectively only on certain layers (this allows you to apply the detection only to enemy characters, for example).
The returned RaycastHit2D returns both the point and normal of the contact where the circle would touch the collider. It also returns the centroid where the circle would be positioned for it to contact at that point.
