使用2D数组创建跳棋碎片 - Pygame

  这是我认为你的代码的一个版本 . 我认为主要的问题是你如何初始化 gameboard 变量：

  gameBoard=[[None]*8]*8
  

  我改为：

  gameBoard=[[None]*8 for _ in range(8)]  # Proper initialization.
  

  因此，它会为每一行创建一个新的 None 值列，而不是在每一行中放置相同的列表 . 这是一个常见的Python新手"gotcha" .

  我还尝试在某种程度上清理，简化和组织代码结构 . 一个值得注意的变化是我将所有这些函数定义移到了主循环之外 - 因为没有理由不止一次这样做，它只会减慢执行速度 .

  还有许多其他的优化可以完成，但是因为你还不适合这里 - 有另一个名为Code Review的网站用于那种事情），我没有实现其中的任何一个......
