Physics2D.OverlapCircleAll

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

参数

point 圆形的中心。
radius 圆形的半径。
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[] 投射结果。

描述

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

This function is similar to OverlapCircle except that all Colliders that fall within the circle 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 circle.

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 OverlapCircleNonAlloc 来避免这种开销。
