RaycastHit 光线投射碰撞 Struct Structure used to get information back from a raycast. 用来获取从raycast函数中得到的信息反馈的结构. 参见:Physics.Raycast, Physics.Linecast, Physics.RaycastAll. Variables变量 point The impact point in world space where the ray hit the collider.在世界空
1. 射线用 Physics.Raycast 都可以判断,用 collider.Raycast 只在某些(不明)情况下可以 void Update() { Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition); RaycastHit hit; // if (collider.Raycast(ray, out hit, 100f)) if (Physics.Raycast(ray,out hit ,100f)) { Debug.Dr
