DeviceRotation  - AS3

The isSupported property is set to true if the accelerometer and gyroscope sensors are available on the device, otherwise it is set to false.

var myTextField:TextField = new TextField();
myTextField.width = 200;
addChild(myTextField);
var deviceRotation = new DeviceRotation();
var isSupported:Boolean = DeviceRotation.isSupported;
checksupport();

function checksupport():void {
    if (isSupported) {
        myTextField.text = "DeviceRotation feature supported";
        deviceRotation.addEventListener(DeviceRotationEvent.UPDATE,deviceRotUpdateHandler);
    } else {
        myTextField.text = "DeviceRotation feature not supported";
    }
}

function deviceRotUpdateHandler(evt:DeviceRotationEvent):void {
    myTextField.text = String("at: " + evt.timestamp + "\n" + "Roll: " + evt.roll + "\n" + "Yaw: " + evt.yaw + "\n" + "Pitch: " + evt.pitch);

}

Specifies whether the user has denied access to the Device Rotation data (true) or allowed access (false). When this value changes, a status event is dispatched.

Related API Elements

Creates a new DeviceRotation instance.

The setRequestedUpdateInterval method is used to set the desired time interval for updates. The time interval is measured in milliseconds. The update interval is only used as a hint to conserve the battery power. The actual time between device rotation vector updates may be greater or lesser than this value. Any change in the update interval affects all registered listeners. You can use the DeviceRotation class without calling the setRequestedUpdateInterval() method. In this case, the application receives updates based on the device's default interval.

Parameters

Dispatched when device rotation changes its status.

This event has the following properties:

The update event is dispatched when the device is rotated in response to updates from the combined readings from accelerometer and gyroscope sensors. The event is dispatched in the following circumstances:

• When a new listener function is attached through addEventListener(), this event is delivered once to all the registered listeners for providing the current value of the device rotation vector in terms of roll pitch and quaternions.
• Whenever device rotation updates are obtained from the platform at device determined intervals.
• Whenever the application misses a change in the device rotation (for example, the runtime is resuming after being idle).

This event has the following properties:
