AS3 basic mc addressing problem

Hello!

Here is my questions:

I have this Document Class:

Code:

package  
{
    import flash.display.MovieClip;
    
    /**
     * ...
     * @author infidel - aka Ovidiu Gheorghe
     */
    public class main extends MovieClip
    {
        public var bg_mc:MovieClip = new MovieClip();
        
        public var redSquare_mc:redSquare = new redSquare();
        public var blueSquare_mc:blueSquare = new blueSquare(this);
        public var greenSquare_mc:greenSquare = new greenSquare();
        
        public function main() 
        {
            composeScene();
            //getAlpha(blueSquare_mc);
        }
        
        private function getAlpha(nume:Object):void
        {
            //bg_mc.alpha = .2;
            trace("alpha: " + nume.alpha);
        }
        
        private function composeScene():void
        {
            this.addChild(bg_mc);
            this.bg_mc.addChild(redSquare_mc);
            
            this.bg_mc.addChild(blueSquare_mc);
            blueSquare_mc.x = stage.stageWidth / 2;
            blueSquare_mc.y = stage.stageHeight / 2;
            
            redSquare_mc.addChild(greenSquare_mc);
            greenSquare_mc.x += 150;
            greenSquare_mc.y += 150;
        }
        
    }
    
}

and a separate class called blueSquare.as attached to blueSquare movieclip in library:

Code:

package  
{
    import flash.display.MovieClip;
    
    /**
     * ...
     * @author infidel - aka Ovidiu Gheorghe
     */
    public class blueSquare extends MovieClip
    {
        public var myPath:Object;
        
        public function blueSquare(passedPath:Object) 
        {
            myPath = passedPath;
            
            // trace1:
            trace(myPath.name);
            
            // trace2:
            trace(myPath.redSquare_mc.alpha);
            
            // trace3:
            trace(myPath.bg_mc.redSquare_mc.alpha);
        }
        
    }
    
}

Questions:

  1. howcome that in my document class I can set the x, y for the greenSquare directly, without “this.redSquare_mc.greenSquare_mc” in front ?

  2. howcome I get an error in my blueSquare.as class when I trace:
    Code:

trace(myPath.bg_mc.redSquare_mc.alpha);

Yes, I know I come from a strong as2 way of thinking!

Tnx a bunch guys,
Ovidiu
