Question

如果有人可以帮助或给我一些指导来解决这些错误，请给我任何提示，或者建议一个更好的方法来学习AS3我会非常感激。

我有一个主要的AS3文件:(我将所有导入都放在不同的行上但由于某种原因，该网站将它们全部放在一行中。）

主要课程：

package
{
    import flash.display.MovieClip
    import flash.events.Event
    import flash.events.KeyboardEvent

    public class DocumentMainNew extends MovieClip
    {
        public function DocumentMainNew():void
        {
            var angela:Hero = new Hero();
            var worm1:Enemy = new Enemy();
            angela.health = 100;
            angela.mana = 100;

            stage.focus = stage;
        }
    }

我收到这些错误:(无法输入错误，因为某些原因会将帖子标记为格式不正确） Errors 感谢您的任何帮助。我真的很抱歉，如果这是一个糟糕的问题，我已经尝试找到这个问题的答案，但无法解决任何问题或找到我应该如何使用类的任何解释。

Answer 1

启用调试（菜单文件 - ＆gt;发布设置 - ＆gt; SWF - ＆gt;允许调试）以了解给您带来麻烦的确切行。

然后，我很确定在 Hero 构造函数中无法访问阶段，因为阶段仅适用于附加的对象到显示列表。你需要：

将 Hero 实例附加到阶段
赶上 Hero

我认为这会奏效。主要课程：

expensive simulation

英雄课程：

var angela:Hero = new Hero;
addChild(angela);
