The most common use of a Ray from the camera is to perform a raycast out into the scene. A raycast sends an imaginary “laser beam” along the ray from its origin until it hits a collider in the scene. Information is then returned about the object and the point that was hit in a ...

eventCamera请参阅:BaseRaycaster。 ignoreReversedGraphics是否应考虑背对射线投射器的图形。 Public Functions Raycast确定光标是否位于场景中的图形元素上方。请参阅:BaseRaycaster。 Inherited members Variables eventCamera用于为此射线投射器生成射线的摄像机。
Rayray=Camera.main.ScreenPointToRay(Input.mousePosition); 利用ScreenPointToRay方法将鼠标点击位置转换为一条射线。 3.3 碰撞检测 if(Physics.Raycast(ray,outvarhit)) 通过Raycast方法检测射线与场景中的物体是否相交,并获取相交信息。 3.4 获取网格信息 MeshCollidermeshCollider=hit.colliderasMeshCollider;Meshmesh=mesh...
main属性。Camera.main是Unity在场景中查找并找到标记为“MainCamera”的摄影机时返回的。

每次进行UI交互时,画布组件都会检査其 eventCamera 属性(在 Inspector 窗口中显示为Event Camera)以确定要使用的相机。默认情况下,2D画布会将此属性设置为MainCamera,但3D画布会将其设置为null。遗憾的是,每次需要EventCamera时,都是通过调用FindObjectWithTag()方法来使用MainCamera。通过标记查找对象并不像使用Find(...
2.因为3d物体上没有canvas上边的GraphicRaycaster所以要Main Camera上添加Physics Raycaster,就相当于UI上的GraphicRaycaster 3.创建一个Cube(或者其他什么随便你,但是确保物体上有collion组件,因为没有碰撞器无法检测射线),作为事件触发的3d物体 4.在3D物体上(你创建的那个cube或者什么)挂上EventTrigger,然后指定怎么触发...
