public static int OverlapPointNonAlloc (Vector2 point, Collider2D[] results, int layerMask= DefaultRaycastLayers, float minDepth= -Mathf.Infinity, float maxDepth= Mathf.Infinity);


minDepth Only include objects with a Z coordinate (depth) greater than or equal to this value.
maxDepth Only include objects with a Z coordinate (depth) less than or equal to this value.
point A point in space.
results Array to receive results.
layerMask Filter to check objects only on specific layers.


int Returns the number of results placed in the results array.


Get a list of all colliders that overlap a point in space.

This function is similar to OverlapPointAll except that the results are returned in the supplied array. The integer return value is the number of objects that overlap 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 when the check is performed frequently.
