Question

JavaScript => static function BoxCastAll(origin: Vector2, size: Vector2, angle: float, direction: Vector2, distance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, minDepth: float = -Mathf.Infinity, maxDepth: float = Mathf.Infinity): RaycastHit2D[];
C# => static RaycastHit2D[] BoxCastAll(Vector2 origin, Vector2 size, float angle, Vector2 direction, float distance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, float minDepth = -Mathf.Infinity, float maxDepth = Mathf.Infinity);

Parameters 参数

origin	The point in 2D space where the shape originates. 在2D空间中，形状的发源点。
size	The size of the shape. 形状的大小。
angle	The angle of the shape. 形状的角度。
direction	Vector representing the direction of the shape. 代表形状方向的向量。
distance	Maximum distance over which to cast the shape. 形状投射的最大距离。
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

RaycastHit2D[] The cast results returned.
投射结果的返回值是RaycatHit2D[]类型。

Description 描述

Casts a box against colliders in the scene, returning all colliders that contact with it.
对场景内的碰撞器们投射出一个箱子，返回所有投射接触到碰撞器。

A BoxCast is conceptually like dragging a box through the scene in a particular direction. Any object making contact with the box can be detected and reported.
方形投射就好像在场景中拖着一个Box向特定的方向移动。任何物体接触到Box会被检测到并报告。

This function is similar to the BoxCast function but instead of detecting just the first collider that is hit, an array of all colliders along the path of the box is returned. The colliders in the array are sorted in order of distance from the origin point. The layerMask can be used to detect objects selectively only on certain layers (this allows you to apply the detection only to enemy characters, for example).
这个函数与BoxCast函数类似，但不是仅仅只返回第一个投射到的碰撞器，而是返回一个所有被检测到的碰撞器的数组。数组内的碰撞器根据他和投射发源点之间的距离排序。图层遮罩可以用于指定检测特定某些图层的对象（比如：这允许您设置检测只适用于敌人角色）。

The returned RaycastHit2D returns both the point and normal of the contact where the box would touch the collider. It also returns the centroid where the box would be positioned for it to contact at that point.
返回的RaycastHit2D类型内包含了投射方形接触到碰撞器的接触点和法线信息。它还返回方形被定位在接触点时的中心点。
