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 fullScreen
fscommand2("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.
