    无法访问属性或方法

    我无法在VideoPlayer类中获取这些值,我想知道这是否与我在Document类中调用这些类的顺序有关:

    文档类 

    package {
    // IMPORTS

    public class TEN extends Global {

        //private consts
        //private vars

        public function TEN():void {
            if (stage) {
                init();
            } else {
                addEventListener(Event.ADDED_TO_STAGE,init);
            }
        }

        private function init(e:Event=null):void {
            removeEventListener(Event.ADDED_TO_STAGE,init);
            // Using the BulkLoader class to phrase XML
        }

        private function onBulkLoadComplete(e:Event):void {
            trace("[BulkLoader] COMPLETE"+"\r");

            Global.xml=loader.getXML("xmldata");
            // I get XML values
            // XML info goes into ARRAYS here

            drawBackground();

    您正在文档类中创建VideoDisplay和PlayerControl的实例。那很好。但是,除非您将PlayerControl对象“pc”的引用传递给VideoControls类,否则ViedoControls类无法知道如何使用pc。您需要发布更多代码,以显示drawVideo和drawControls方法的触发顺序。

    您可能需要在文档类中添加类似的内容: 

    drawVideo();
drawControls();
vd.playerControls = pc;
pc.videoDisaply = vd;

    然后换一个 

    private var pc:PlayerControls;
to
public var playerControls:PlayerConrols;


    pc.progressBar.width = ns.time * pc.progressTotalW / videoDuration;
to
playerControls.progressBar.width = ns.time * playerControls.progressTotalW / videoDuration;

    视频显示也有同样的变化。更改为公共变量、更改名称以及使用vd名称更改引用。我建议更改VideoDisplay和PlayerControl类中变量的名称的原因是,这看起来很难看: 

    vd.pc = pc
pc.vd = vd

    是的,那是你的问题。当你有 

    pc=new PlayerControls;

    然后,在VideoDisplay中,您也可以做同样的事情 

     pc        = new PlayerControls();  // <- PlayerControls.as

    这不引用与DocumentClass具有相同的PlayerControl。您的意思是,创建一个新的PlayerControl实例并将其保存在VideoDisplay中。现在它们是两个不同的例子。我上面写的解决方案应该适合你。

    addChild 和 progressBar.width PlayerControls 当 createProgress 被称为。

    对不起,我误解了这个问题。所以这条线引起了悲伤 

    pc.progressBar.width = ns.time * pc.progressTotalW / videoDuration;

    Timer . 我没有看到执行它的代码,但我猜第一个事件是从 计时器 视频显示在 玩家控制 已创建,或在 progressBar 玩家控制 是创建的。

    如果这不能解决这个问题,您可以发布init函数的两个调用顺序的代码吗( drawVideo drawControls ),这些类和计时器初始化代码的构造函数。从你那里得到的,我不能说更多,因为我不能计算出控制流。

    您实际上在哪里传递对的引用 PlayerControls 到 VideoDisplay ? 据我所知,从你的代码,你的不是。您需要在尝试访问它之前设置它。

    比如: 

    myVideoDisplay.pc = myPlayerControls

    也许我只是错过了一些东西。。。

    试着改变这两行,看看这是否能让你走得更远。 

    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() });
