How to adjust this AS2 to AS3?

Question

the AS2 code is:

MovieClip.prototype.setModel = function(m)
{
    this.model = m;
    this.drawModel(m);
}

MovieClip.prototype.drawModel = drawModel;

I tried:

package
{
    import flash.display.MovieClip;

    public class Prototype extends MovieClip
    {
        public function Prototype()
        {
            super();
        }

        public function setModel(m)
        {
            this.model = m;
            this.drawModel(m);
        }

        public function setDrawModel(m)
        {
            this.drawModel = m;
        }

    }
}

but there is no "this.model" nither "drawModel(m)" in MovieClip.

Any idea?

Answer 1

You have define model and drawModel. I only see setModel and setDrawModel and no variables.

So if you add following inside the class:

private var model:type;

Then your this.model will work.

Answer 2

 public class Whatever extends MovieClip
 {
    private var _model:DisplayObject;

    public function set model(m:Object):void
    {
       this._model = m;
       this.drawModel();
    }

    private function drawModel():void
    { 
        _model.graphics.beginFill(0); //etc...
    }
 }

Then in another class , you can do this

 var whatever:Whatever = new Whatever();
 whatever.model = new DisplayObject();
