事实上,UnityAPI里的RaycastHit2D(EN)或RaycastHit2D(CN)解释地比较清楚。这里只针对其中较难理解的fraction做些解释。 关于RaycastHit2D-fraction API对它的解释是这样的 RaycastHit2D.fractionpublicfloat fraction ;Description描述Fractionofthe distance along the ray that the hit occurred.射线上发生命中的距离的...

Unity中射线检测有多种 API.Unity Documentation描述中的两种: |RaycastAll| Casts a ray through the Scene and returns all hits. Note that order is not guaranteed. | |RaycastNonAlloc| Cast a ray through the Scene and store the hits into the buffer. | ...
在API文档中Ray是一个结构体【Struct】 (对于没有语言基础的同学来说理解这个可能会比较吃力,可以暂时简单理解成是unity人为设计规定的一种数据类型,可以像int那样使用它) static function Ray (origin :Vector3, direction :Vector3) : Ray 【构造】
struct in UnityEngine Description 用于从射线投射获取信息的结构。 另请参阅:Physics.Raycast、Physics.Linecast、Physics.RaycastAll。 Variables barycentricCoordinate命中的三角形的重心坐标。 collider命中的 Collider。 distance从射线原点到撞击点的距离。
struct in UnityEngineDescription 在2D 物理中,有关射线投射检测到的对象的返回信息。 A raycast is used to detect objects that lie along the path of a ray and is conceptually like firing a laser beam into the Scene and observing which objects are hit by it. The RaycastHit2D class is used ...
