Question

JavaScript => public static function SphereCastNonAlloc(origin: Vector3, radius: float, direction: Vector3, results: RaycastHit[], maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): int;

C# => public static int SphereCastNonAlloc(Vector3 origin, float radius, Vector3 direction, RaycastHit[] results, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters 参数

origin	The center of the sphere at the start of the sweep. 扫描开始球体的中心点。
radius	The radius of the sphere. 球体的半径。
direction	The direction in which to sweep the sphere. 球体扫描的方向。
results	The buffer to save the hits into. 储存碰到对象的缓冲器。
maxDistance	The max length of the sweep. 扫描的最大长度。
layermask	A Layer mask that is used to selectively ignore colliders when casting a ray. 选择投射的层蒙版。
queryTriggerInteraction	Specifies whether this query should hit Triggers. 指定是否查询碰到触发器。

Returns 返回值

int The amount of hits stored into the results buffer.

储存在results缓冲器中碰撞器的数量。

Description 描述

Cast sphere along the direction and store the results into buffer.

沿direction方向投射球体，并储存在results缓冲器中。

This is variant of Physics.SphereCastAll, but instead of allocating the array with the results of the query, it stores the results into the user-provided array. It will only compute as many hits as fit into the buffer, and store them in no particular order. It's not guaranteed that it will store only the closest hits. Generates no garbage.

这个是Physics.SphereCastAll的变种，而是把查询的结果储存在提供的数组中。这个仅计算碰到对象的多少，储存到缓冲器中，并没有特定的顺序。它不能保证它只存储最近的碰撞。不产生垃圾。
