Collider2D The collider overlapping the circle.
Checks if a collider falls within a circular area.
円はワールド座標の中心点や半径により定義されます。オプションとして layerMask を設定することで特定レイヤーのオブジェクトのみ判定できます。
Although the Z axis is not relevant for rendering or collisions in 2D, you can use the minDepth and maxDepth parameters to filter objects based on their Z coordinate. If more than one collider falls within the circle then the one returned will be the one with the lowest Z coordinate value. Null is returned if there are no colliders in the circle.

contactFilter | The contact filter used to filter the results differently, such as by layer mask, Z depth. Note that normal angle is not used for overlap testing. |
results | The array to receive results. The size of the array determines the maximum number of results that can be returned. |
int
Returns the number of results placed in the results
array.
Checks if a collider is within a circular area.
The circle is defined by its centre coordinate in world space and by its radius.
This function returns the number of colliders found and places those colliders in the results
array. The results can also be filtered by the contactFilter
. Note that filtering by normal angle is not available for overlap functions.
