我再次被可怕的Flash错误所困扰：无法访问属性或方法。
我正在构建一个新的视频播放器，我需要将我的进度条（在PlayerControls.as中创建）的总宽度发送到我的VideoPlayer.as类。以及从我的VideoPlayer.as类中的更新函数控制进度条的宽度。
我无法在我的VideoPlayer类中获取这些值，我想知道它是否与我在Document类中调用这些类的顺序有关：

^出于某种原因我无法定位PlayerControls.as内的progressBar.width
答案 0 :(得分：1)
尝试更改拨打addChild和progressBar.width的顺序。另外，请确保在调用PlayerControls时将createProgress添加到舞台。
<强>更新
抱歉，我误解了这个问题。所以正是这条线引起了悲伤
pc.progressBar.width = ns.time * pc.progressTotalW / videoDuration;
您列出的功能的顺序与您调用它们的顺序无关。我认为问题出在你的Timer。我没有看到执行它的代码，但我猜想从Timer到VideoDisplay的第一个事件调度是在创建PlayerControls之前，或者在progressBar内部{{1已创建。
如果这不能解决问题，请为init函数（PlayerControls，drawVideo）的调用顺序发布代码，这些类的构造函数和Timer init码。根据你的情况，我不能多说，因为我无法解决控制流程。
答案 1 :(得分：1)
您实际上将PlayerControls的引用传递给VideoDisplay？据我所知，从您的代码中可以看出，不是。您需要在尝试访问它之前设置它。
如下所示：
myVideoDisplay.pc = myPlayerControls
也许我只是错过了一些东西......
答案 2 :(得分：1)
您正在DocuementClass中创建VideoDisplay和PlayerControls的实例。那样就好。但除非您将PlayerControls对象“pc”的引用传递给VideoControls类，否则ViedoControls类无法知道如何处理pc。您需要发布更多代码以显示drawVideo和drawControls方法被触发的顺序。
您可能需要在文档类中使用类似的东西：
drawVideo();
drawControls();
vd.playerControls = pc;
pc.videoDisaply = vd;
然后改变
private var pc:PlayerControls;
to
public var playerControls:PlayerConrols;
当然要改变
pc.progressBar.width = ns.time * pc.progressTotalW / videoDuration;
to
playerControls.progressBar.width = ns.time * playerControls.progressTotalW / videoDuration;
VideoDisplay也有相同的变化。使用vd名称更改为public var，更改名称和更改引用。我建议更改VideoDisplay和PlayerControls类中变量名称的原因是因为这看起来很丑陋：
vd.pc = pc
pc.vd = vd
pc=new PlayerControls;
在DocumentClass中，您正在创建一个新的PlayerControl实例，并将其作为pc存储在DocuemntClass中。所以，如果你问DocumentClass是什么PC，它会说：“它是我存储的PlayerControls的一个实例”。
然后，在VideoDisplay中你做同样的事情
pc = new PlayerControls(); // <- PlayerControls.as
这不引用DocumentControls DocumentClass所具有的相同内容。你是说，创建一个PlayerControls的新实例并将其保存在VideoDisplay中。现在他们是两个不同的例子。我上面写的解决方案应该适合你。
答案 3 :(得分：1)
尝试更改这两行，看看是否能让你更进一步。
pc.addEventListener("onPlay",vd.playVideo);
pc.addEventListener("onPause",vd.pauseVideo);
到
pc.addEventListener("onPlay",function(e) { vd.playVideo() });
pc.addEventListener("onPause",function(e) { vd.pauseVideo() });
