Physics2D.OverlapPointAll

切换到手册
public static Collider2D[] OverlapPointAll (Vector2 point, int layerMask= DefaultRaycastLayers, float minDepth= -Mathf.Infinity, float maxDepth= Mathf.Infinity);

参数

minDepth 仅包括 Z 坐标(深度)大于或等于该值的对象。
maxDepth 仅包括 Z 坐标(深度)小于或等于该值的对象。
point 空间中的点。
layerMask 筛选器,用于检查仅在指定层上的对象。

返回

Collider2D[] 返回的投射数量。

描述

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

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.

注意,该函数将为返回的 Collider2D 数组分配内存。如果需要频繁进行检查,可以使用 OverlapPointNonAlloc 来避免这种开销。
