我在外部设置了一个代码。类文件 这个类文件允许一些鼠标功能，例如使用色板进行颜色转换。现在代码运行良好，但它似乎只在第 1 帧中工作。我想在加载 as 时将我的所有作品从第 1 帧移动到第 4 帧。class 文件以在第 4 帧中伴随我的功能。所以基本上我只是想将所有内容从第 1 帧移动到第 4 帧。这是如何完成的？我尝试发布设置并将 eport 类选项更改为第 4 帧，但没有成功。这是我在外部的代码。文件。

我认为您的问题是您以前使用 Drawing5 作为文档类。现在您想在第 4 帧中单独运行它。为此，您需要为 Drawing5 类提供对您的 swfs 阶段的引用，以便它现在知道在哪里可以找到所有这些对象。

var d5:Drawing5 = new Drawing5(this);

然后向 Drawing5 类添加一个名为 _container （或其他东西）的属性

private var _container:MovieClip;

然后在您的 Drawing 5 构造函数中，更改它以适应新的 var 并设置容器

public function Drawing5(container:MovieClip){
    _container = container;
}

然后在 Drawing5 中，更改引用列表或按钮等对象的所有调用，以将容器包含在路径中，如下所示：

// Respond to mouse events
_container.swatch1_btn.addEventListener(MouseEvent.CLICK,swatchHandler,false,0,false);

我希望我正确理解了您的问题，这会有所帮助。

问题是当您加载/调用此类时，它正在寻找舞台上的对象，如果它们不存在，它将引发错误。所以你不应该调用它，直到它与它正在寻找的项目在同一个框架上。因此，如果您要查找的所有项目都在第 4 帧上，那么您应该调用它。

所以转到第 4 帧并添加以下代码：

var myDrawings5 = new Drawing5();

另一种选择是将当前在构造函数中的代码移动到一个名为 init() 的新公共函数中。然后，您可以随时加载该类，但在项目出现在舞台上之前不要调用 init()。

public function Drawing5(){
  // now emtpy
}

public function init(){
  // move code from Drawing5() here
}

然后加载它并在需要的地方调用它

var myDrawings5 = new Drawing5();
myDrawings5.init();
