使用可能な向きの中で、必要に応じて自動で向きを変更します
When this option is assigned to the Screen.orientation property, the screen will auto-rotate so that the bottom of the screen image points downwards. The orientations that can be used are set by the Screen.autorotateToLandscapeLeft, Screen.autorotateToLandscapeRight, Screen.autorotateToPortrait and Screen::autorotateToPortraitUpsideDown properties. For example, if Screen.autorotateToPortrait and Screen::autorotateToPortraitUpsideDown are both true but the others are false then the auto-rotation will never choose either of the landscape options even when the device is held with the long side of the screen pointing downwards.
function Start () {
Screen.autorotateToPortrait = true;
Screen.autorotateToPortraitUpsideDown = true;
Screen.orientation = ScreenOrientation.AutoRotation;
}
