Actionscript 3 擦洗孙子的时间线会导致先前卸载的孙子swf的声音播放，干扰当前播放孙子swf的声音

我面临什么问题？ 我有一个父文件。它按概述文件的名称加载子级。概述文件进一步加载许多孙子文件。我在父文件上有一个时间轴清理器。它同时清理子文件和孙子文件。问题是，如果我加载孙子文件，则卸载它。然后加载下一个孙子文件并拖动时间轴，先前加载的孙子文件的声音开始播放。我怎样才能阻止它？？请帮助，我已经努力了，但我不能解决，我是业余爱好者，没有正式的编程知识。谢谢

我提供了一个链接，以防有人想看到代码

要复制错误，请打开父文件。点击装甲链接，然后点击主页按钮卸载它。现在，点击炮兵链接，拖动洗涤器

现在，你将听到之前卸载的“装甲”孙子swf的重叠声音和炮兵swf的声音一起播放

删除时间线编码周期。对不起，我并没有理解你们，若我并没有在时间线上写代码，那个么我应该在哪里写代码？你是在建议把actionscript文件分开吗？是的，没错。请看，时间线代码在初始化其变量方面有其技巧，而且您在某个帧上编写的所有代码在您转到该帧时都会执行，无论是正常播放还是gotoAndStop调用。这会使您的变量重新初始化，包括额外的加载请求，并且还会重建显示中的其他对象，这会导致各种错误。没有任何时间线编码的单独AS3文件更可靠，因为您完全控制代码流和变量处理。还需要考虑将MCS转换为精灵，如果需要持久性的话，让那些动画化的MCS作为控件精灵的孩子，这样他们的动画就不会干扰变量分配和其他代码流，也就是说将代码与视觉分离开来。请大家帮忙。SoundMixer.stopAll将无法工作，因为它会静音所有声音，包括当前播放孙子的声音。声音变换也是如此。知道是什么导致了这个问题吗。根本原因是什么？
