Question

JavaScript => static function OverlapPointAll(point: Vector2, layerMask: int = DefaultRaycastLayers, minDepth: float = -Mathf.Infinity, maxDepth: float = Mathf.Infinity): Collider2D[];
C# => static Collider2D[] OverlapPointAll(Vector2 point, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

Parameters 参数

point	A point in world space. 一个世界空间中的点。
layerMask	Filter to detect Colliders only on certain layers. 只在某些层过滤检测碰撞器。
minDepth	Only include objects with a Z coordinate (depth) greater than this value. 只包括Z坐标(深度)大于这个值的对象。
maxDepth	Only include objects with a Z coordinate (depth) less than this value. 只包括Z坐标(深度)小于这个值的对象。

Description 描述

Get a list of all colliders that overlap a point in space.
得到一个列表，里面是所有与世界中的点重叠的碰撞器。

This function is similar to OverlapPoint except that all colliders that overlap the point are returned. The colliders in the returned array are sorted in order of increasing Z coordinate. An empty array is returned if there are no colliders over the point.
除了会返回所有与点重合的碰撞器，这个函数与OverlapPoint相似。碰撞器在返回的数组中会被用Z坐标排序。如果没有碰撞器与点重叠，就会返回一个空的数组。

Note that this function will allocate memory for the returned Collider2D array. You can use OverlapPointNonAlloc to avoid this overhead if you need to make the check frequently.
注意这个函数会分配内存给返回的Collider2D数组。在需要频繁做这个检测的时候，你可以使用OverlapPointNonAlloc这个函数去避免这些开销。
