See in Glossary and Android devices. Detecting a change in orientation or forcing a specific orientation is useful for creating game behaviors that depend on how the user is holding the device.
Retrieve device orientation by accessing the Screen.orientation property. Orientation can be one of the following:
| Orientation | Behavior |
|---|---|
| Portrait | The device is in portrait mode, with the device held upright and the home button at the bottom. |
| PortraitUpsideDown | The device is in portrait mode but upside down, with the device held upright and the home button at the top. |
| LandscapeLeft | The device is in landscape mode, with the device held upright and the home button on the right side. |
| LandscapeRight | The device is in landscape mode, with the device held upright and the home button on the left side. |
Set Screen.orientation to one of the above orientations, or use ScreenOrientation.AutoRotation to control the screen orientation. When you enable auto-rotation, you can still disable some orientation on a case-by-case basis.
See the API documentation for Screen.autorotateToPortrait, Screen.autorotateToPortraitUpsideDown, Screen.autorotateToLandscapeLeft and Screen.autorotateToLandscapeRight for more information.
