Flex 3预加载程序与Flash 11/11.5一起死亡

我真的需要帮助，我已经处理这件事好几个月了。基本上，我有一个旧的Flex3应用程序和一个定制的预加载程序。一旦每个人都升级到Flash 11和11.5，预加载程序就消失了。我正试图让Flash Builder 4.7在3.6库中链接，但遗憾的是，它似乎悄悄地失败了。即使是标准预加载程序也与“加载0的库”相关联（不过它确实显示了）…我正在使用现在经典的“DownloadProgressBar”扩展自定义预加载程序模式

package com.timberdesignco.preloader
{
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.events.ProgressEvent;
    import flash.events.TimerEvent;
    import flash.utils.Timer;

    import mx.events.FlexEvent;
    import mx.preloaders.DownloadProgressBar;

    public final class CustomPreloader extends DownloadProgressBar {
        public  var loader : LoadScreen;
        private var _timer : Timer;

        public function CustomPreloader() 
        {
            super(); 
        }

        override public function initialize() : void
        {
            super.initialize();

            this.loader = new LoadScreen();
            this.addChild(this.loader);

            this._timer = new Timer(10);
            this._timer.addEventListener(TimerEvent.TIMER, handleTimerTick);
            this._timer.start();
        }

        override public function set preloader(preloader : Sprite):void 
        {                   
            preloader.addEventListener(ProgressEvent.PROGRESS,  SWFDownLoadScreen);
            preloader.addEventListener(Event.COMPLETE,          SWFDownloadComplete);
            preloader.addEventListener(FlexEvent.INIT_PROGRESS, FlexInitProgress);
            preloader.addEventListener(FlexEvent.INIT_COMPLETE, FlexInitComplete);
        }

        private function SWFDownLoadScreen(event : ProgressEvent) : void
        {
            var prog : Number = event.bytesLoaded / event.bytesTotal * 100;
            if (this.loader)
            {
                this.loader.progress = prog;
            }
        }

        private function handleTimerTick(event : TimerEvent) : void
        {
            this.stage.addChild(this);
            this.loader.x = (this.stage.stageWidth  - this.loader.width)  / 2 - 35;
            this.loader.y = (this.stage.stageHeight - this.loader.height) / 2;
            this.loader.refresh();
        }

        private function SWFDownloadComplete(event : Event) : void {}

        private function FlexInitProgress(event : Event) : void {}

        private function FlexInitComplete(event : Event) : void 
        {      
            this.loader.ready = true;
            this._timer.stop();
            this.dispatchEvent(new Event(Event.COMPLETE));
        }

        override protected function showDisplayForInit(elapsedTime:int, count:int):Boolean
        {
            return true;
        }

        override protected function showDisplayForDownloading(elapsedTime:int,
                                                  event:ProgressEvent):Boolean
        {
            return true;
        }
    }
}

所以我得到了你的预加载程序的简化版本

这是我的密码。然后我们可以讨论哪些部分应该用另一种方式完成（如果有的话）

嗨，我试着理解你的问题，如果它仍然是真实的。您能告诉我为什么使用Loader作为LoadScreen的基类吗？在这种情况下，LoadScreen的用途是什么？我已经更正了您的代码，并得到以下结果。这是你的目标吗？是的，这正是我需要的。你介意分享固定代码吗？好的，我当然会。我只是想知道这是你想要的。
