刺激下载时加载swf游戏但不正常时出错

Question

好的，所以当我运行 loader.swf 时，它可以很好地加载我的 game.swf。但是当我刺激下载时，恰好在 70% 时，我的 game.swf 音乐开始播放，并显示以下错误：

TypeError：错误 #1009：无法访问空对象引用的属性或方法。 在 GAME_fla::MainTimeline/frame11()

还有

错误 #2044：未处理的 IOErrorEvent：。 text=Error #2036：加载从未完成。

正常加载时游戏运行良好。当我在线上传并检查它是否正常工作时，此问题仍然存在。它没有。我的加载器适用于其他 swf 文件。如何解决这个问题？

如果我添加它们，其他框架将无法访问这些变量。

之前的加载器代码：

var myrequest: URLRequest = new URLRequest("GAME.swf");
var myloader: Loader = new Loader();
myloader.load(myrequest);

myloader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progresshandler);
function progresshandler(myevent: ProgressEvent): void {

  var myprogress: Number = myevent.target.bytesLoaded / myevent.target.bytesTotal;


  bar_mc.scaleX = myprogress;
  percentage_text.text = Math.round(myprogress * 100) + "%";
}

myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, finished);
function finished(myevent: Event): void {

  addChild(myloader);
  removeChild(percentage_text);
  removeChild(bar_mc);
  removeChild(background_mc);
}

加载器代码之后：

var myrequest: URLRequest = new URLRequest("GAME.swf");

import flash.net.URLRequest;
import flash.display.MovieClip;
import flash.events.Event;
var myloader: Loader = new Loader();


myloader.load(myrequest);

function progresshandler(myevent: ProgressEvent): void {

  var myprogress: Number = myevent.target.bytesLoaded / myevent.target.bytesTotal;

  bar_mc.scaleX = myprogress;
  percentage_text.text = Math.round(myprogress * 100) + "%";
}



myloader.contentLoaderInfo.addEventListener(Event.INIT, finished);

myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, completes);


function finished(myevent: Event): void {

  addChild(myloader);
  removeChild(percentage_text);
  removeChild(bar_mc);
  removeChild(background_mc);
}

function completes(myevent: Event): void {


  var loaderInfo: LoaderInfo = myevent.target as LoaderInfo;
  var swf: Object = loaderInfo.content;
  swf.play();

}

Answer 1

也许你应该试试这个活动：ADDED_TO_STAGE。 ADDED_TO_STAGE 事件在对象添加到阶段时触发（非常奇怪的名称和相关性），即执行 addChild 方法时。

尝试在外部 SWF 的 Main 类中收听此事件，因此，在将相应对象添加到舞台之前不会执行任何代码（现在即使在加载过程中您也可以听到音乐。

举个例子：

 package 
 {
        import flash.display.Sprite;
        import flash.events.Event;

        public class TheMainClassOfYourExternalSWF extends Sprite 
        {
               public function TheMainClassOfYourExternalSWF() 
               {
                    addEventListener(Event.ADDED_TO_STAGE, initHandler);
               }

               private function initHandler(event:Event):void 
               {
                    removeEventListener(Event.ADDED_TO_STAGE, initHandler);
                    trace('this is the stage:', stage);
                    trace('this is my parent:', this.parent);
                    // here you start to include your logic
               }
        }
  }

如果您使用 FLA 文件并使用时间线添加代码，您可以尝试：

 addEventListener(Event.ADDED_TO_STAGE, initHandler);

 function initHandler(event:Event):void 
 {
         removeEventListener(Event.ADDED_TO_STAGE, initHandler);
         // here you start to include your logic, call your functions, initialise your instances...
 }

Answer 2

在加载外部 swf 时，需要注意两件事。

首先加载的swf的第一帧在Event.INIT触发时开始播放，而不是在Event.COMPLETE触发时开始播放。事件 init 在第一帧可以播放时触发，而 complete 则在整个 swf 加载时触发。

第二阶段或根仅在已添加到已添加到阶段的显示列表中时在加载的 swf 中可用。当 Event.INIT 触发时，加载的 swf 没有阶段或根，因此 swf 的第一帧不应有任何对阶段或根的引用。

如果您的 swf 不使用文档类，那么只需使用 stop() 将您的第一个框架设为空，然后一旦加载并添加到显示列表，让您的 swf 转到您拥有所有代码的第 2 框架。
