在主时间线中的另一个影片剪辑中执行影片剪辑

Question

我正在尝试创建一个将在其他项目中使用的影片剪辑。 它实际上是 15 个谜题的游戏。 除了当有人赢得游戏时如何执行影片剪辑之外，我一切都正常。 检查 win 是否有效，这样我就知道何时需要播放该剪辑，但我只是不知道如何播放。 所有东西都需要保留在 Puzzle 影片剪辑下。 我将附上代码。 我使用“假”胜利来测试，所以我不必每次想测试它时都玩游戏。 我是一位拥有 40 年 COBOL 编程经验的老手，但对 Flash 还很陌生。 我需要知道的是： 1）win_mc放在哪里 2）如何从我测试胜利的 mousedown 处理程序中调用它 3）非常感谢对编码的评论。 我想以正确的方式学习Flash。

谢谢你的帮助。 射线

Answer 1

好吧，首先看起来这段代码是 ActionScript 2 而不是 ActionScript 3。这对于开始工作来说非常好，但 AS2 基本上是一个死胡同 - Adob​​e 不会用新功能来更新它。

如果您只是为了好玩而接触 Flash，那么 AS2 就不错。 如果您从职业/工作的角度来研究它，那么您也最好看看 AS3。 事实上，现在了解这两者可能非常有价值，因为那里有各种各样的项目。

现在，至于你的问题！

一般来说，最好避免将代码放置在主时间线以外的任何地方（更好的是使用外部类）。 当代码放置在 GUI 元素中时，由于范围问题，可能会导致代码难以查找且难以调试（正如您所发现的！）。

mouseDown 事件处理程序附加到拼图影片剪辑的子级，而不是时间轴。 这意味着此代码在该剪辑的范围内运行 - 因此所有对 _parent 的引用。 这意味着您可以简单地将 win_mc 剪辑添加到拼图剪辑（在图块顶部的它自己的层中），然后从 mouseDown 处理程序中使用 _parent.Win_mc 引用它。
