I have been struggling for a couple of days with an issue in Flash CS4. I am re-structuring an old game project into a Main class which handles the mainMenu, playGame, etc. functions. I have a ship added from the "game", which is added by Main.
The issue is "myShip" works as expected, except it's never visible. I've checked a lot of times, and both myShip and its containter (game) visible properties are always true. Alpha values are not the problem either, nor layers nor depth. Every other child I've added from "game" works just fine, but "myShip" refuses to be visible.
Any ideas as to why this could happen? I do not know how what to try next to solve the problem. Any help would be very appreciated. The code for the Main, Game and Ship class is below.
Thank you!
Code from the Main class:
public class Main extends Sprite {
public var mainMenuDisplay:MainMenuDisplay;
public var game:Game;
public var gameOverMenu:GameOverMenu;
public function Main() {
showMainMenu();
}
public function showMainMenu() {
mainMenuDisplay = new MainMenuDisplay(this);
gameOverMenu=remove_movie_clip(gameOverMenu);
addChild(mainMenuDisplay);
}
public function showGameOver() {
gameOverMenu = new GameOverMenu(this);
game=remove_movie_clip(game);
addChild(gameOverMenu);
}
public function playTheGame() {
game = new Game(this);
mainMenuDisplay = remove_movie_clip(mainMenuDisplay);
gameOverMenu=remove_movie_clip(gameOverMenu);
stage.addChild(game);
}
private function remove_movie_clip(clip:*) {
if (clip) {
removeChild(clip);
}
return null;
}
}

Some basics that you have to know in order to understand what's going on.
It's a very common mistake to add things to stage.
Here's what the documentation of addChild says http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObjectContainer.html#addChild%28%29
objects should not be added to the Stage, directly, at all
I guess people add DispalyObjects to stage because they think it is
"the stage" that they see and interact with in the Flash authoring
environment. But it's not. stage.addChild() is not the same
thing as dragging a symbol from the library onto the screen. What by
default represents the main time line is the root property.
However, if you add anything to stage directly, its root property and its stage property both reference the same object,
which is regularly only referenced by stage. stage is some
container that your .swf is added to when running in the flash
player.
The documentation of addChildAt says this about the index: http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObjectContainer.html#addChildAt%28%29
The child is added at the index position specified. An index of 0 represents the back (bottom) of the display list for this DisplayObjectContainer object.
Applying these basics, the following happens:
stage object, instantiates your main class
and adds that instance to stage, it is the child with the index 0.stage.addChildAt(mySprite, 1); is executed,
adding mySprite as a second child to stage. With index of 1 it is
rendered in front of the object that is at index 0, which happens to
be the instance of your main class AKA your .swf file. I hope that
anything being rendered "outside the .swf file" illustrates well
enough why adding things to stage is not recommended.this.addChild(myShip); happens. (Which is actually the
proper way to do it; no need to use this here:addChild(myShip);
is all you need.) and adds the ship to the display list. Assuming all
of its parents are added to the display list as well, it will be
displayed.mySprite in front of
the instance of your main class and filled it with a content in
drawGradient() which covers up everything else.In all honesty, the best solution would be to start over from scratch. Working with this code will not help you in any way. Even working yourself through it and making it work somehow will not make you understand anything better (except for how not to do things). It seems like the only motivation to modify this code to use classes was for the sake of doing it. Forcing such old code into the object oriented paradigm will not work very well. The benefits of oop will not be apparent, making this experience even more frustrating.
Last but not least, do not roll your own transition code. There are many libraries that do this (including flash's own Tween class http://www.republicofcode.com/tutorials/flash/as3tweenclass/ or the popular tweenlite http://greensock.com/tweenlite)
