| point | A point in world space. |
| layerMask | Filter to check objects only on specific layers. |
| contactFilter | The contact filter used to filter the results differently, such as by layer mask and Z depth. Note that the normal angle is not used for overlap testing. |
Collider2D The collider overlapping the point.
Checks a point against colliders in the PhysicsScene2D, returning the first intersection only.
An "OverlapPoint" is conceptually like looking at the Scene through an infinitely small hole to determine what can be seen. Any Collider2D seen can be detected and reported.
This function returns a Collider2D that overlaps the point or NULL if nothing overlaps.
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). Overloads of this method that use contactFilter can filter the results by the options available in ContactFilter2D.
This function will never detect an EdgeCollider2D as a point cannot ever perfectly overlap the infinitely thin edge defined by that collider.

int
Returns the number of results placed in the results array.
Checks a point against colliders in the PhysicsScene2D, returning all intersections.
An "OverlapPoint" is conceptually like looking at the Scene through an infinitely small hole to determine what can be seen. Any Collider2D seen can be detected and reported.
This function returns an array of Collider2D that overlap the point.
The integer return value is the number of objects that intersect the point (possibly zero) but the results array will not be resized if it doesn't contain enough elements to report all the results. The significance of this is that no memory is allocated for the results and so garbage collection performance is improved. Note that you will always get zero results if you pass an empty array.
