[squigy_dunkens]

i tried to make a progress bar for this so that everything would be loaded before it starts, i searched and found somone who showed me, but it didnt work. how can i make this work? the code is this

package
{
    import flash.display.Sprite;
    import flash.display.Stage;
    import flash.events.Event;
    import flash.events.KeyboardEvent;
    import flash.ui.Keyboard;
    import flash.display.Loader;
    import flash.net.URLRequest;
    import flash.text.TextField;
    import flash.controls.ProgressBar;
    import flash.controls.ProgressBarMode;

    public class gaia extends Sprite
    {
        private var pb:ProgressBar = new ProgressBar();
        private var leaf:Loader;
        private var instructions:TextField = new TextField();
        public function gaia ()
        {
            pb.width = 150;
            pb.mode = ProgressBarMode.POLLED;
            pb.source = Loader;
            pb.move(20,20);
            instructions.text = "use the arrow keys to move around";
            instructions.y = 10;
            instructions.x = 20;
            instructions.width = 500;
            leaf = new Loader;
            leaf.load (new URLRequest("http://a2.cdn.gaiaonline.com/gaia/members/ava/04/41/207d91bd6d4104_flip.png"));
            leaf.x = 20;
            leaf.y = 20;
            addChild (pb);
            addChild (instructions);
            addChild (leaf);
            stage.addEventListener (KeyboardEvent.KEY_DOWN,keyPressedDown);
        }
        private function keyPressedDown (event:KeyboardEvent):void
        {
            var x_speed:int=0;
            var y_speed:int=0;
            switch (event.keyCode)
            {
                case Keyboard.LEFT :
                    leaf.load (new URLRequest("http://a2.cdn.gaiaonline.com/gaia/members/ava/04/41/207d91bd6d4104.png"));
                    x_speed = -2;
                    break;
                case Keyboard.RIGHT :
                    leaf.load (new URLRequest("http://a2.cdn.gaiaonline.com/gaia/members/ava/04/41/207d91bd6d4104_flip.png"));
                    x_speed = 2;
                    break;
                case Keyboard.UP :
                    y_speed = -2;
                    break;
                case Keyboard.DOWN :
                    y_speed = 2;
                    break;
            }
            leaf.x += x_speed;
            leaf.y += y_speed;
        }
    }
}

and my terminal spit this out

can anyone tell me how to make this work?

Hi, use another swf to load the swf that you want loaded(if that makes sense). Create a completely new flash file with the same dimensions and settings as the one you want loaded. Then add

var req:URLRequest = new URLRequest("my_flash_file.swf");
var myLoader:Loader = new Loader();
myLoader.load(req);



myLoader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, checkProgress);

function checkProgress(p:ProgressEvent):void {
	var percent:int = (p.currentTarget.bytesLoaded / p.currentTarget.bytesTotal) * 100;
	bar.width = percent * 2;
}

myLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete);
function onComplete(e:Event):void {
	bar.visible = false;	
        addChild(myLoader);
}

You will need to add a bar movieclip to the stage and name the instance "bar".


Hope this makes sense, I havent had much sleep so my head is a bit cloudy.
