Question

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

Parameters 参数

pointA	One corner of the rectangle. 矩形的一个角。
pointB	Diagonally opposite corner of the rectangle. 矩形的对角。
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 fall within a rectangular area.
获取一个列表包括所有碰撞器，那些碰撞器是落入一个矩形区域中的才行。

This function is similar to OverlapArea except that all colliders that fall within the area 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 within the area.
这个函数与OverlapArea类似，不同的是这个函数会返回所有落入矩形区域的碰撞器。碰撞器在返回的数组中会被用Z坐标排序。如果没有碰撞器在区域内，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 OverlapAreaNonAlloc 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OverlapAreaNonAlloc这个函数去避免这些开销。
