我正在尝试将我的actionscript 3代码从我之前使用的时间轴转换为包。
我需要在代码的开头定义一些字典。
但是当我在类中运行以下代码时，actionscript会返回错误。
public var S_USA:Dictionary = new Dictionary();
S_USA["x"] = -299;
S_USA["y"] = -114;
S_USA["bynavn"] = "New York";
这是错误：“1120：访问未定义的属性S_USA。
编辑：发布整个代码：

答案 0 :(得分：0)
您是在构造函数或函数中设置此数据吗？
修改
嗯，从哪里开始...
1）你知道如果你要创建超过1个类的实例，静态的技巧就不会起作用吗？在这种情况下，如果你只有1个主要类，那么它会起作用，但是omg ... Imho在静态变量中存储数据并不好......
2）如果您已经宣布：
public var bynavntxt:TextField;
public var intervall:TextField;
稍后再做
bynavntxt = new TextField() ;
intervall = new TextField() ;
不需要输入。
3）稍后在Main，你有类似的东西：
var mcOut = new OutCursorClip();
this.addChild(mcOut);
var mcIn = new InCursorClip();
this.addChild(mcIn);
为什么要声明具有相同名称但没有Type？
的新变量Waaaaaay你有：
public var mcIn:MovieClip;
public var mcOut:MovieClip;
因此已经声明了这些变量。通过再次声明它们，你正在创造本地的。谨防！！在那之后，顶部的那些将是空的。
答案 1 :(得分：0)
1）在构造函数中填写字典（我已经通过评论看到你已经这样做了。）
2）您已经使用public var bynavntxt:TextField;为bynavntxt分配了类型，您不应该只使用bynavntxt:TextField = new TextField(); bynavntxt= new TextField();再次执行此操作。
这与类似类型的所有其他变量相同。
3）确保此类将成为您的“文档类”/“编译类”，否则您将无法访问“stage”变量。为了确保您可以访问舞台变量，您可以随时执行：
/* Inside Constructor */
addEventListener(Event.ADDED_TO_STAGE, _onAddedToStage);
/* Outside Constructor */
private function _onAddedToStage(e:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, _onAddedToStage);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyHandler);
stage.addEventListener(KeyboardEvent.KEY_UP, keyHandler);
}
同样，如果这将是编译的类，可以跳过它。
