Question

In an attempt to organize my code, I’m trying to split up my (lengthy) main controller class into separate files, but my new files must still have access to the variables and functions of the main controller class.

I’m trying to cut and paste code from my controller class into a new class/file, allowing the controller class to call the new class, and allowing the new class to have access to the controller class’s properties and function.

Assuming I’m not totally bludgeoning appropriate design patterns, below is my unsuccessful attempt at accomplishing this task:

package
{   
import flash.display.Sprite;
import flash.events.Event;

public class Test extends Sprite
    {
    public var myString:String;

    public function Test()
        {
        if  (stage)
            init(null);
            else
            addEventListener(Event.ADDED_TO_STAGE, init);
        }

    private function init(evt:Event):void
        {
        if  (hasEventListener(Event.ADDED_TO_STAGE))
            removeEventListener(Event.ADDED_TO_STAGE, init);

/////////////// MOVE COMMENTED CODE TO NEW FILE ///////////////////////
//      
//      //Assign The String A Value
//      myString = "Hello world";
//      
//      //Draw A Blue Square
//      var sq:Sprite = new Sprite();
//      sq.graphics.beginFill(0x0000FF);
//      sq.graphics.drawRect(10, 10, 100, 100);
//      sq.graphics.endFill();
//      super.addChild(sq);
//      
//      //Call Tracer Function
//      tracer();
//
//////////////////////////////////////////////////////////////////////

        //Call pasted method in NewFile.as
        NewFile.myNewFunction();     // <- this doesn't work
        }

    public function tracer():void
        {
        trace(myString);
        }
    }
}

new file doesn’t have access to the Controller class – doesn’t work. how can i write the new file so that it does have access to the properties, functions, stage, etc. of the Controller class, as if its code was never removed and is still in its original place.

package
{   
public class NewFile
    {
    public static function myNewFuntion():void
        {
        //Assign The String A Value
        myString = "Hello world";

        //Draw A Blue Square
        var sq:Sprite = new Sprite();
        sq.graphics.beginFill(0x0000FF);
        sq.graphics.drawRect(10, 10, 100, 100);
        sq.graphics.endFill();
        super.addChild(sq);

        //Call Tracer Function
        tracer();
        }
    }
}

public class MainClass extends Sprite
{
    private var subClass:SubClass;

    public function MainClass
    {
       var controller:Controller = new Controller();

       subClass = new SubClass(controller);
       addChild( subClass );
    }

    private function init():void
    {
       subClass.doWhatever();
    }
}

public class Controller
{

    public function doThis():void
    {
     }
    public function doThat():void
    {
         trace("controller do that...");
     }
    public function doSomethingElse():void
    {
     }
}

public class Subclass extends Sprite
{
     private var controller:Controller;

     public function Subclass(controller:Controller)
     {
         this.controller = controller;
         trace( "new Subclass instance!" );
     }

     public function doWhatever():void
     {
         controller.doThat();
     }
}
