Python 尝试使用Pygame制作一个石头布剪刀游戏

我想做一把pygame石头剪刀，但我不知道如何从玩家1切换到玩家2。我希望顶部的player1文本改为player2，代码用来存储第一个玩家选择的内容。问题是，我只是测试它的岩石，只有当你按住鼠标左键并将鼠标放在正确的位置时，它才会改变，而不是只需点击一次

首先，所有这些变量都需要是全局变量，而不是在主游戏循环中（因此，在运行时变量应该在上面），否则当你增加它们，然后通过循环返回时，它们都将重置为初始实现的位置，循环将继续作用于它们。如果没有一个近乎全新的重新启动或严格的编辑，我不能简单地向您展示使这项工作正常运行所需要做的一切。我建议您选择一个教程，指导您制作不同的游戏，学习制作游戏所需的语法和部分，然后回到您的RPS游戏。一旦您了解制作游戏功能所需的部分，正如@Pmac1687所指出的，代码将重新设置主循环中的所有状态变量，因此，状态在每次循环迭代时都会丢失

此外，代码不是获取单个鼠标事件，而是依赖于鼠标的当前状态。这可能会在缓慢的人释放鼠标按钮之前多次循环执行“click has ocked”（单击已发生）代码。将此更改为在事件上触发可修复此问题

屏幕油漆的顺序也有点错误。在屏幕充满白色之前，一些东西正在被写入屏幕

无论如何，我重新安排了代码，并为鼠标添加了事件处理。屏幕布局和点击现在似乎做了一些事情。希望这能给你一个正确的方向
