gotoAndStop()；flashdevelop或flex

Question

我有一个嵌入电影剪辑的自定义类。当我尝试使用父类的时候，比如gotoAndStop()。它会忽略该方法。我想知道我做错了什么。下面是我的代码。我在我的构造函数中调用了这个方法，谢谢！

游戏对象类

package com.objects 
{
    import com.eapi.IGameObject;
    import flash.display.MovieClip;
    /**
     * ...
     * @author Anthony Gordon
     */
    public class GameObject extends MovieClip implements IGameObject
    {


        public function GameObject() 
        {

        }

    }

}

英雄班。构造函数中的gotoAndStop()

package com.objects 
{
    import flash.display.MovieClip;
    import flash.events.*;
    /**
     * ...
     * @author Anthony Gordon
     */
    [Embed(source='../../../bin/Assets.swf', symbol='Hero')]
    public class Hero extends GameObject
    {   
        private var aKeyPress:Array;
        private var jumpDisabled:Boolean = false;

        public function Hero() 
        {
            gotoAndStop(1) ///<----------------Doesnt stop. Just keeps playing
            wY = 150;
            wX = 90;
            speed = .5;
            aKeyPress = new Array();
            TheGame.sr.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
            TheGame.sr.addEventListener(KeyboardEvent.KEY_UP,keyUpListener);
        }

        private function keyDownListener(e:KeyboardEvent):void {
            //trace("down e.keyCode=" + e.keyCode);         
            aKeyPress[e.keyCode]=true;
        }

        private function keyUpListener(e:KeyboardEvent):void {
            //trace("up e.keyCode=" + e.keyCode);
            aKeyPress[e.keyCode]=false;
        }

        override public function UpdateObject():void
        {
            Controls();
            updatePosition();
        }

        private function Controls():void
        {

            if (aKeyPress[38])//Key press up
                ;//dy -= speed;         
            else if (aKeyPress[40])//Key press down
                dy += speed;

            if (aKeyPress[37])//left
            {
                dx -= speed;
            }
            else if (aKeyPress[39])//Right
            {
                dx  += speed;
            }

            if (aKeyPress[32]){//space
                jump();
            }


        }//End Controls

        private function jump():void
        {
            if (!jumpDisabled)
            {
                if (onGround)
                {
                    gotoAndStop(10);
                    dy = -15;
                    jumpDisabled = true;
                }
            }
            else
            {
                jumpDisabled = false;               
            }
        }
    }

}

把它弄清楚。我忘了我的movieclip被封装在另一个电影剪辑里了。所以我不得不把英雄符号里面的电影片段叫做

Answer 2

问题是，当你嵌入一个电影剪辑的swf时，实际上你得到的是一个电影剪辑，并添加了进入真正电影剪辑的子加载器。

你必须尝试像这样的东西

var aMovie:MovieClip;
Loader(this.getChildAt(0)).getLoaderInfo.addListener(Event.Complete, methodEventCompleteName);

function methodEventCompleteName(e:Event)
{
  aMovie = MovieClip(Loader(this.getChildAt(0)).content);
}

我真的建议你试着学习使用SWC文件。我将他导出到flash SWC集成开发环境中，然后添加一个库文件夹到我的项目中，然后在flashdeveloper IDE中右击cs5文件并选中“添加到库”选项。在类中可以直接将movieClip名称实例化到SWC文件中，如下所示：

var aMovie:MovieClip = new MyMovieClipFromSWC() as MovieClip;

它已经完成了:D

希望这对某些人有帮助。因为我花了大概3周的时间才弄明白并最终弄明白了…关于它的信息还不够...

你应该添加一个侦听器来知道它何时被添加到舞台上，并在那里初始化你的剪辑。

public function Hero() {
    if ( stage ) _init( );
    else addEventListener(Event.ADDED_TO_STAGE, _init );
}

private function _init( e:Event = null ):void {
    removeEventListener( Event.ADDED_TO_STAGE, _init );
    gotoAndStop(1) ///<----------------Doesnt stop. Just keeps playing
    wY = 150;
    wX = 90;
    speed = .5;
    aKeyPress = new Array();
    TheGame.sr.addEventListener(KeyboardEvent.KEY_DOWN, keyDownListener);
    TheGame.sr.addEventListener(KeyboardEvent.KEY_UP,keyUpListener);
}

另外，我认为这篇由senocular阅读Order of operations的文章将会非常有趣。它解释了时间轴对象和对象创建中的帧执行。
