Question

JavaScript => public static function RaycastNonAlloc(ray: Ray, results: RaycastHit[], maxDistance: float = Mathf.Infinity, layerMask: int = DefaultRaycastLayers, queryTriggerInteraction: QueryTriggerInteraction = QueryTriggerInteraction.UseGlobal): int;

C# => public static int RaycastNonAlloc(Ray ray, RaycastHit[] results, float maxDistance = Mathf.Infinity, int layerMask = DefaultRaycastLayers, QueryTriggerInteraction queryTriggerInteraction = QueryTriggerInteraction.UseGlobal);

Parameters 参数

ray	The starting point and direction of the ray. 带有开始点和方向的射线。
results	The buffer to store the hits into. 储存碰到对象的缓冲器。
maxDistance	The max distance the rayhit is allowed to be from the start of the ray. 从射线开始允许投射的最大距离。
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.

返回储存在results缓冲器中碰撞器的数量。

Description 描述

Cast a ray through the scene and store the hits into the buffer.

在场景投射射线并储存碰到的对象到缓冲器中。
