我正在尝试为我的编码项目制作一个相当简单的国际象棋游戏，希望在某个时候也能实现一个计算机对手，有点卡在如何添加移动限制和函数来检测此时游戏结束的问题上。身体是由@sloth 设计的，我添加了它。
我已经完成了相当简单的事情，加载所有部件并更改板颜色，但我不太确定此时该做什么。任何帮助，将不胜感激！

首先，如果你只是想把事情做好，你最好使用 python-chess 库。否则，要检查国际象棋比赛的结束，您需要查看是否有少数可能的条件为真：
所以仅仅因为游戏规则就相当复杂。
现在，如果您想选择合法的移动，请阅读有关代表董事会的 0x88 方法。它代表两块棋盘的位置，一块包含棋子，另一块是非法领土。这提供了对合法移动的简单检查，因为您只需和具有生成移动的棋盘一起检查合法性。在实施滑动件、king 和 en passant 时要小心。
好吧，国际象棋已经有了一个 python 库。 它被称为蟒蛇国际象棋。 您可以在 here 找到文档 也值得阅读 这篇文章 以快速了解图书馆 这是一个使用这个库构建的简单国际象棋游戏的命令行版本
