We do not recommend Flash Lite development on current Nokia devices, and all Flash Lite articles on this wiki have been archived. Flash Lite has been removed from all Nokia Asha and recent Series 40 devices and has limited support on Symbian. Specific information for Nokia Belle is available in Flash Lite on Nokia Browser for Symbian. Specific information for OLD Series 40 and Symbian devices is available in the Flash Lite Developers Library.

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(lv.klError == 0){
//Read the position.
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.

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.
