In this post we’ll see how to use accelerometer in Flash Lite with Kuneri Lite. We’ll do a small example of the moving ball application, however simpler than the original application.

First of all, you have to create two layers, with names ‘content’ and ‘actions’. After this, create a movieclip with a circle like the showed below. Put the movieclip in the Stage with an instance name ‘ball_mc’.

After this, put the below code in the first frame of the ‘actions’ layer.

`//Set fullScreenfscommand2("FullScreen", true); var lv:LoadVars = new LoadVars();var X, Y, acelX, acelY, posX, posY; //Reset the kuneri Lite variables.klXAxis = 0;klYAxis = 0; lv.onLoad = function(success:Boolean){	if(success) 		if(lv.klError == 0){			//Read the position.			lv.load("http://127.0.0.1:1001/Basic/accelerometer                        ?klCommand=readsensor");			X = lv.klXAxis;			Y = lv.klYAxis;		}} onEnterFrame = function():Void{	//Calculate the respective constant acceleration.	if(X > 0)	   acelX = -1;	else acelX = 1;	if(Y > 0)	   acelY = -1;	else acelY = 1; 	posX = Math.abs(X/10) * acelX;	posY = Math.abs(Y/10) * acelY;	 	moveBall(posX, posY);	//Verify the limits of screen.	verifyPosition(ball_mc._x, ball_mc._y);} function verifyPosition(posX:Number, posY:Number):Void{	if(posY <= 10)		ball_mc._y = 10;	if(posY >= 310)		ball_mc._y = 310;	if(posX <= 10)		ball_mc._x = 10;	if(posX >= 230)		ball_mc._x = 230;} function moveBall(posX:Number, posY:Number):Void{	ball_mc._x += posX;	ball_mc._y += posY;} //Start the accelerometer, before first read.lv.load("http://127.0.0.1:1001/Basic/accelerometer?klCommand=startsensor"); stop();`

In this example the acceleration is constant, because this is a simple example for to create a moving ball with Flash Lite using KuneriLite accelerometer plugin by Flash Lite.
