Object Oriented AS 3.0

I'm new to OOP AS 3.0, so.. I have a question.

I have two files Main.as and LoadTheXML.as

in the Load开发者_JAVA技巧TheXML class I have loadTheXML function, in there sortXML function and in there an array picturePathList that I want to use in Main.as

in Main.as I have a code that launches the loadTheXML function:

var loadedXML:LoadTheXML = new LoadTheXML(urlVar);

so... In Main.as I'd like to write:

            var rand:Number = Math.round(Math.random() * (a - 1));
            var mainLoader:Loader = new Loader();
            var mainRequest:URLRequest = new URLRequest(picturePathList[rand]);
            mainLoader.load(mainRequest);
            mainLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, mainLoaded);

            function mainLoaded(e:Event):void {
                mainPicPlacementX = (stage.stageWidth / 2) - (mainLoader.width / 2);

            so on and so on.... 
            }

How should I call the picturePathList array from LoadTheXML class.

Thanks!!!

HERE I'll put the files - please see, because I didn't get what to do and how... The Files

I want the above mentioned code to be moved to Mainc.as I guess this will have more logic, and anyway I'd like to see how it's done.. If you find some tutorial I'd like to see that too.. Thanks!

Make your LoadToXML object's picturePathList property publicly accesible via a getter method:

public class LoadTheXML
{
    private var _picturePathList:Array;

    public function get picturePathList():Array
    {
        return _picturePathList;

    }// end function

    // ...

}// end class

In general AS3 is asynchronous; it means, it should not wait for to complete the first statement before it go to the 2nd statement.

So u should listen an event object to check whether the task has been completed or not. You can attain this EventDispatcher object.

So u should dispatch an event object in sortXML function.

dispatchEvent ( new Event ( Event.COMPLETE ) );

and in the Main.as.

private function init():void
{
    loadedXML = new LoadTheXML(urlVar);
    loadedXML.addEventListener ( Event.COMPLETE, handleXMLLoaded );
}

private function handleXMLLoaded (e:Event):void
{
   var rand:Number = Math.round(Math.random() * (a - 1));
   var mainLoader:Loader = new Loader();
   var mainRequest:URLRequest = new URLRequest(loadedXML.picturePathList[rand]);
   mainLoader.load(mainRequest); 
   .....
   .....   
}
