Actionscript 3 - Class Referring Errors - actionscript-3

Question

I a document class (Main) and a class connected to a symbol (MainMenu), and I get an error I just can't figure how to solve.. I get this error:
1136: Incorrect number of arguments. Expected 1.
it is reffering to "public var mainMenu = new MainMenu();" in my document class.
Anyways, here are my classes:
Main(document class):
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.Stage;
public class Main extends MovieClip {
public var mainMenu = new MainMenu();
public function Main() {
// constructor code
startGame();
}
public function startGame(){
addChild(mainMenu);
}
public function initGame(event){
//Adding player and such..
}
}
}
MainMenu:
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
public class MainMenu extends MovieClip {
private var logo = new Logo();
public function MainMenu(main:Main) {
// constructor code
mainMenu = new MainMenu(this);
logo.addEventListener(MouseEvent.CLICK, main.initGame);
placeButtons(event);
}
public function placeButtons(event:Event){
logo.addEventListener(MouseEvent.CLICK, initGame);
logo.x = - logo.width/2;
logo.y = 50;
addChild(logo);
trace ("MainMenu added");
}
}
}
Thanks

A few pointers...
Be mindful of your indentation.
Datatype your variables, arguments, and function returns.
Your MainMenu class was self instantiating itself (that's an infinite loop)
If you really need direct access to another classes function, consider making the child class extend the parent class. Alternatively, you could make the specific function a static function and call the function directly off the class without passing variable references. For example: Main.initGame()
Here are your classes, with a potential solution...
Main:
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.display.Stage;
public class Main extends MovieClip {
public var mainMenu:MainMenu;
public function Main() {
mainMenu = new MainMenu();
addChild(mainMenu);
}
public function initGame(e:Event):void {
//Adding player and such..
}
}
}
MainMenu:
package {
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;
public class MainMenu extends MovieClip {
private var logo:Logo;
public function MainMenu() {
// Wait for it to be added to the parent.
logo = new Logo();
addChild(logo);
addEventListener(Event.ADDED_TO_STAGE, placeButton);
}
private function placeButton(e:Event):void {
// We only need this to happen once, so remove the listener
removeEventListener(Event.ADDED_TO_STAGE, placeButton);
// Now that we've formed the connection, we can reference the function dynamically
logo.addEventListener(MouseEvent.CLICK, this["parent"].initGame);
logo.x = - logo.width/2;
logo.y = 50;
}
}
}
I've left the structure as similar to your original intent as possible, but the above function reference is poor form. As a general rule, children should not have connections to their parents as it's a potential memory leak. You might instead add the event listener from your Main class.
