Does anyone know what could be the problem?
this is what i have in my main menu as:
package
{
import flash.display.MovieClip;
import flash.events.MouseEvent;
import HomeTitel;
import InstBtn;
import NieuwBtn;
public class Hoofdmenu extends MovieClip
{
private var homeTitel:HomeTitel;
private var instBtn:InstBtn;
private var nieuwBtn:NieuwBtn;
private var inst:Instructions;
private var level1:Level1;
public function Hoofdmenu():void
{
placeHomeTitel();
placeInstructionsBtn();
placeNieuwBtn();
}
private function placeHomeTitel():void
{
homeTitel = new HomeTitel();
addChild(homeTitel);
homeTitel.x = 275;
homeTitel.y = 20;
}
private function placeInstBtn():void
{
instBtn = new InstBtn();
addChild(instBtn);
instBtn.x = 275;
instBtn.y = 225;
instBtn.addEventListener(MouseEvent.CLICK, gotoInstructions);
}
private function gotoInstructions(event:MouseEvent)
{
inst = new Instructoins();
addChild(inst);
}
private function placeNewBtn():void
{
newBtn = new NewBtn();
addChild(newBtn);
newBtn.x = 275;
newBtn.y = 175;
newBtn.addEventListener(MouseEvent.CLICK, gotoLevel1);
}
private function gotoLevel1(event:MouseEvent):void
{
level1 = new Level1();
addChild(level1);
}
}
}
this is what i have in my level1 as:

Answer 1

I think you should rebuild/redesign the structure of your game.
Now, your code does few strange things:
in your Main class: everytime you call function gotoLevel1 you create a new instance of Level1
in your Level1 class in the function level1Opn you create another instance of 'Level1' and you add it inside Level1 - quite a mess.
This isn't just small code tweak - you should rebuild it quite significantly.

Answer 2

Seems like you never remove level1 from your menu. Even though you remove all children from Level 1, the movieclip will still exist and be on top of your menu.
I would recommend reading though this tutorial, as it will teach you some basic skills about structuring your code, and specific game development features (sound, preloading, saving things in cookies): http://gamedev.michaeljameswilliams.com/2008/09/17/avoider-game-tutorial-1/
