Physics2D.OverlapAreaAll

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

参数

pointA 矩形的一角。
pointB 矩形 A 角的对角。
layerMask 筛选器,用于检查仅在指定层上的对象。
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。

返回

Collider2D[] 返回的投射数量。

描述

Get a list of all Colliders that fall within a rectangular area.

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.

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 OverlapAreaNonAlloc 来避免这种开销。
