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

Parameters

minDepthOnly include objects with a Z coordinate (depth) greater than or equal to this value.
maxDepthOnly include objects with a Z coordinate (depth) less than or equal to this value.
pointA point in space.
resultsArray to receive results.
layerMaskFilter to check objects only on specific layers.

Returns

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

Description

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.
