必要时朝着任何启用的方向自动旋转屏幕。
        When you assign ScreenOrientation.AutoRotation to the Screen.orientation property, the screen auto-rotates so that the bottom of the image points downwards.
To set permitted the orientations, use the following properties
        
          
            Screen.autorotateToLandscapeLeft
          
          
            Screen.autorotateToLandscapeRight
          
          
            Screen.autorotateToPortrait
          
          
            Screen.autorotateToPortraitUpsideDown
          
        
        You can set a combination of orientations.
For example, you can set Screen.autorotateToPortrait and Screen.autorotateToPortraitUpsideDown to true but leave the others as false. In this case, the auto-rotation never chooses either of the landscape options.
WebGL builds only support auto-rotation on the mobile Chrome browser, and will only allow orienting to a subset of combinations, these are:
        
          Individual orientations
          Opposite pairs of orientations
          All four of the above orientations.
        
        If another combination is set, auto-rotation defaults to all four orientations.
Note: Auto-rotation on WebGL only works in full-screen mode.
