Question

JavaScript => static function OverlapAreaNonAlloc(pointA: Vector2, pointB: Vector2, results: Collider2D[], layerMask: int = DefaultRaycastLayers, minDepth: float = -Mathf.Infinity, maxDepth: float = Mathf.Infinity): int;
C# => static int OverlapAreaNonAlloc(Vector2 pointA, Vector2 pointB, Collider2D[] results, 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。
results	Array to receive results. 填充结果的数组。
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。

Returns 返回值

int The number of results returned.
int 返回结果的数量。

Description 描述

Get a list of all colliders that fall within a specified area.
获取落入特殊区域内的所有碰撞器

This function is similar to OverlapAreaAll except that the results are returned in the supplied array. The integer return value is the number of objects that fall within the area (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.
