两种不同写法的射线检测 1.获取鼠标点击的物体 if (Input.GetMouseButtonDown(0)) { Ray ray = MainCamera.ScreenPointToRay(Input.mousePosition); //以摄像机为原点创建一条射线 RaycastHit hit; if (Physics.Raycast(ray, out hit)) //点击到了带有碰撞体的物体 { Transform clickObjTrans = hit.transform; //获取点击
ARCore中提供了根据屏幕坐标.视口大小及view. project矩阵计算从屏幕坐标发射一条射线的方法,此方法用于3D拾取. class Ray { public final Vector3f origin;//射线起点 public final Vector3f direction;//射线方向 public Ray(Vector3f origin, Vector3f direction) { this.origin = origin; this.direction = direction
unity3d 怎样获得当前鼠标点击的对象 最佳答案 var ray = Camera.main.ScreenPointToRay (Input.mousePosition);var hit : RaycastHit;if (Physics.Raycast (ray, hit, 100)) { var target: GameObject = hit.collider.gameObject//获得点击的物体 if(Input.getMouseButtonDown("0")) { t
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
Calculate the Distance Between Two Points in PHP There are a lot of applications where it is useful to know the distance between two coordinates. Here, you'll find a PHP function that takes the latitude and longitude of two points and returns the dis
