public Ray ScreenPointToRay (Vector3 pos);
public Ray ScreenPointToRay (Vector3 pos, Camera.MonoOrStereoscopicEye eye);


eye Optional argument that can be used to specify which eye transform to use. Default is Mono.



Resulting ray is in world space, starting on the near plane of the camera and going through position's (x,y) pixel coordinates on the screen (position.z is ignored).

スクリーンスペースはピクセルで定義されます。画面の左下端は (0,0); 右上端は (pixelWidth -1,pixelHeight -1)。

//Attach this script to your Camera
//This draws a line in the Scene view going through a point 200 pixels from the lower-left corner of the screen
//To see this, enter Play Mode and switch to the Scene tab. Zoom into your Camera's position.
