我的问题是，当我按下 Pattern1 中的按钮时，Pattern2 开始 1 次，之后 Pattern1 继续我按下按钮的位置，运行 1x 波谷，之后模式 2 正常重复。任何想法如何解决它？就像当我按下按钮时，第一个 Pattern1 会重复无穷大。但是当我再次按下它时，当 Pattern1 正在运行时，它会按原样转到 Pattern2，但它只会重复 Pattern2 1 次，然后它会恢复 Pattern1，我按下按钮，然后它应该重复 Pattern2。
所以主要问题是 Pattern1 在 pattern2 中运行 1x 时间；
感谢帮助

问题是你在pattern1()中有那个while循环，你检查按钮，增加a，然后调用pattern2()。它调用 pattern2 一次，然后返回到该点以完成模式 1。我认为您无法修复此代码。如果您希望能够处理模式中间的按钮按下，您将不得不重写整个内容，以便模式不会阻塞。与其让函数调用一次并贯穿整个模式，不如想象一个函数被一遍又一遍地调用，并且只在模式中迈出一小步。
