Create a moving ball using accelerometer with Kuneri Lite
Hi all,
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.
