我正在使用Adobe Animate CC和CreateJS创建游戏的开始阶段，并且出现以下错误：Uncaught ReferenceError：未定义lib。基本上现在，我只是想让背景和一些随机数出现在屏幕上。我已经在Adobe Animate中将背景和随机数创建为符号，并且通过为它们分配“链接”来给它们一个类名。我已经在HTML中包含了由Animate创建的javascript文件以及指向CreateJS和以下代码的链接：
这是我的Javascript代码：
class NumberedBox extends createjs.Container
{
constructor(number=0)
{
super();
var movieclip = new lib.NumberedBox();
movieclip.numberedText.text = number;
this.addChild(movieclip);
movieclip.x = Math.random() * 200;
movieclip.y = Math.random() * 200;
}
}
class Game {
constructor()
{
this.canvas = document.getElementById("canvas");
this.stage = new createjs.Stage(this.canvas);
createjs.Ticker.framerate = 60;
createjs.Ticker.on("tick", this.stage);
this.stage.addChild(new lib.Background());
this.stage.addChild(new NumberedBox(88));
}
}
var game = new Game();
我得到的错误是在这行代码（上面）上： this.stage.addChild（new lib.Background（））;
这是CreateJS创建的代码：

var p; // shortcut to reference prototypes
var lib={};var ss={};var img={};
lib.ssMetadata = [];

function mc_symbol_clone() {

clone.gotoAndStop(this.currentFrame);

关于我在做什么错的任何想法？谢谢您的帮助！

在提供的脚本源中，lib参考仅在createjs上下文中定义，而在外部文档/ Windows上下文中未定义。您需要调用AdobeAn.getComposition(id).getLibrary()以获得对lib的引用并访问其属性（要使用的id值似乎嵌入在脚本源中）

不同于canvas和stage属性，并不是所有地方都可以访问lib属性。实例化Game类时，必须将其作为参数发送。像这样：
class NumberedBox extends createjs.Container
{
constructor(lib, number = 0)
{
super();
var movieclip = new lib.NumberedBox();
movieclip.numberedText.text = number;
this.addChild(movieclip);
movieclip.x = Math.random() * 200;
movieclip.y = Math.random() * 200;
}
}
class Game
{
constructor(lib)
{
this.lib = lib;
this.canvas = document.getElementById("canvas"); // you can call the canvas property from anywhere without doing this
this.stage = new createjs.Stage(this.canvas); // a stage is already created for you
createjs.Ticker.framerate = 60;
createjs.Ticker.on("tick", this.stage);
this.stage.addChild(new lib.Background());
this.stage.addChild(new NumberedBox(lib, 88));
}
}
var game = new Game(lib); // assuming that this line is being called from some timeline in your FLA document
这个问题的答案也可以在https://forums.adobe.com/message/10690481#中找到。感谢所有回答这个问题的人。我感谢您的帮助。 -雷蒙娜

lib 不再可以作为全局变量访问，因此会出现错误。您可以通过修改已发布的HTML代码来存储lib的引用，也可以使用以下间接方法来访问它：
var lib = AdobeAn.getComposition(AdobeAn.bootcompsLoaded[0]).getLibrary();
