我想保持完全控制我的比赛从主要影片剪辑和别的地方。但是，我不想通过构造函数传递它的实例也不做其子女的任何的 .parent 的参考啄。似乎过于workaroundish和不稳定的。

I want to keep total control over my game from the Main MovieClip and nowhere else. But I don't want to pass its instance through constructors neither do any .parent reference thingy from its children. Seems too workaroundish and unstable.

一个样本情况：

public class Main extends MovieClip {
    public function Main() {
        addChild(new MainMenu());
    }

    public function startGame():void {
        trace("Game started");
    }
}

public class MainMenu extends Sprite {
    public function MainMenu() {
        var option:Option = new Option(); // Some BitmapData library linkage
        option.addEventListener(MouseEvent.CLICK, clicked);
        addChild(option);
    }

    public function destroy():void {
        // set null/dispose/removeChildren/removeEventListener/etc.
    }

    private function clicked(evt:MouseEvent):void {
        // Should trigger startGame() here (how?) to keep the flow at Main,
        destroy(); // since this has nothing to do with it anymore
    }
}

我想对于一些单身样的解决方案，但没有静态类，在AS3中。它似乎不好的做法，从我研究了（是吗？）。

I wished for some Singleton-like solution, but there's no static class in AS3. And it seems bad practice from what I researched (or is it?).

嗯，我只是想从做的一切主要观点与典雅code 的或至少的正式做法的。我怎样才能做到这一点？ （请告诉我这是可能的... ：秒）

Well, I just want to do everything from Main perspective with elegant code or at least official practice. How can I do this? (Please, tell me this is possible... :s)

推荐答案

我觉得有2个方法，你可以考虑一下： 静态实例：

I think there are 2 more ways that You can think about : Static instance :

public static var main:Main;
public function Main() {
    main = this;
    ...
}

和值：

public function MainMenu() {}

private function clicked(evt:MouseEvent):void {
    Main.main.startGame();
}

或者用一些静态调度，如果你的应用程序是不是太大了：

Or use some static dispatcher if Your app is not too big :

public static var dsp:EventDispatcher = new EventDispatcher();
public function Main() {
    dsp.addEventListener("StartGame",stageGame);
    ...
}

和在MainMenu的：

and in mainmenu :

 private function clicked(evt:MouseEvent):void {
    Main.dsp.dispatchEvent(new Event("StartGame"));
 }

在这里，您可以随时创建其他类，将处理事件指派/听。

Here You can always create additional class that will handle event dispatching / listening .
