import flash.sensors.Accelerometer;

var accelX:Number;
var accelY:Number;
var fl_Accelerometer:Accelerometer = new Accelerometer();

//Get Accelerometer Property
fl_Accelerometer.addEventListener(AccelerometerEvent.UPDATE, fl_AccelerometerUpdateHandler);
//Move Object, moveCar);

//Get Accelerometer Movement
function fl_AccelerometerUpdateHandler(event:AccelerometerEvent):void
    accelX = event.accelerationX;
    accelY = event.accelerationY;

//Control Car with Accelerometer
function moveCar(evt:Event){ -= accelX*30; += accelY*30;
//Limit platform
