as3 calling a function in Main.as Document Class from another class - actionscript-3

Question

I am sure this is a popular question but I can't find the exact answer I need. I simply need to access a function or functions created in the Main.as document class. I have tried several methods and they do not seem to work. Here is one example I tried.
anotherClass.as // This needs to access functions Main.as
package com
{
import Main;
public class anotherClass
{
private var stageMain:Main;
public function anotherClass()
{
// tries to call a function in Main.as called languageLoaded. NO WORK!
stageMain.languageLoaded("English");
// in the Main.as languageLoaded is a public function
}
}
}

Answer 1

The cleaner way is to simply pass a reference to Main to the constructor of the class you want to be able to access it.
For example, your AnotherClass could look like this:
class AnotherClass
{
private var _main:Main;
public function AnotherClass(main:Main)
{
_main = main;
_main.test(); // Success!
}
}
And your main class:
class Main
{
public function Main()
{
var another:AnotherClass = new AnotherClass(this);
}
public function test():void
{
trace("Success!");
}
}

Answer 2

public class MainDoc extends MovieClip // as long as it extends eventDispatcher you re fine
{
private var otherClass:OtherClass;
public function MainDoc()
{
otherClass = new OtherClass();
otherClass.addEventListener("otherClassCustomEvent", onOtherClassReady);
otherClass.startLogic();
}
public function onOtherClassReady(event:Event = null)
{
trace("from other class:", otherClass.infoToShare) // traces "from other class: YOLO!"
}
}
public class OtherClass extends EventDispatcher // must extend the event dispatcher at least
{
public var infoToShare:String;
public function OtherClass()
{
}
public function startLogic()
{
// do what you got to do
// when you have your data ready
infoToShare = "YOLO!";
dispatchEvent("otherClassCustomEvent");
}
}
Once you're confortable with that, you can start looking into building custom events that could carry the variable to send back

Answer 3

Ok I got the following code to work. It's really a messy solution but I didn't know of a better way. It works. I just hope it's stable and does not use a lot of resources.
If you have a much better Idea I am open.
Here is the MainDoc.as
package {
import flash.display.MovieClip;
import flash.events.*;
import com.*;
import com.views.*;
import flash.display.*;
import flash.filesystem.*;
import com.greensock.*;
import com.greensock.easing.*;
import flash.system.System;
public class mainDoc extends MovieClip
{
/// (Get Main Doc flow) this creates an instace of the main timeline
/// and then I send it
private static var _instance:mainDoc;
public static function get instance():mainDoc { return _instance; }
/// Calls the defaultVars.as in to "vars".
var vars:defaultVars = new defaultVars();
public function mainDoc()
{
/// Makes this class ready to be passed to defautVars.as
_instance = this;
// Sends the _instance to defaulVars.as to be accessed later.
vars.getMainDoc(_instance);
// Calls a function in defaultVars.as and loads a var
vars.loadButtonVars("English");
}
}
}
Here is the defaultVars.as
package com {
import flash.display.Stage;
import flash.events.*
import flash.net.*;
import flash.display.*;
import flash.filesystem.*;
public class defaultVars
{
/// Makes the MainDoc.as a MovieClip
// Not sure if this is good but it works.
public var MainDoc:MovieClip;
public function defaultVars()
{
}
public function getMainDoc(_instance:MovieClip)
{
trace("CALLED" + _instance);
/// receives the _instance var and its converted to a MovieClip
// This can now be used in any function because I declared it a public var.
MainDoc = _instance;
}
public function loadButtonVars(Language:String)
{
myLoader.load(new URLRequest("Languages/" + Language + "/vars.xml"));
myLoader.addEventListener(Event.COMPLETE, processXML);
function processXML(e:Event):void
{
myXML = new XML(e.target.data);
/// Home Screen Buttons
homeT = myXML.Button.(#Title=="homeT");
homeB1 = myXML.Button.(#Title=="homeB1");
homeB2 = myXML.Button.(#Title=="homeB2");
homeB3 = myXML.Button.(#Title=="homeB3");
homeB4 = myXML.Button.(#Title=="homeB4");
homeB5 = myXML.Button.(#Title=="homeB5");
/// HERE IS WHERE I CALL FUNCTION from MainDoc after xml is loaded.
/////////////////
trace("xml loaded!!!! " + homeB1);
MainDoc.languageLoaded(Language);
}
}
}
}
