更新：添加完整脚本 - 启动脚本时，转到播放然后启动。它将运行调查问卷，但不会像你看到的那样更新（很快，然后重置;可能是由于它所在的循环）。
所以，首先：嗨伙计们。我尝试在pygame中运行一个简单的问卷。到目前为止，事情看起来还不错。但是，我遇到了一个问题，到目前为止我无法解决。我尝试在pygame窗口中运行一个函数（def_quiz），但是当我把这个函数放在＆＃39;而真正的＆＃39;在play_function中它继续循环（逻辑上）。我尝试将其粘贴到其他地方，例如在真实的＆＃39;之上声明，但然后我的按钮不再工作了。我错过了什么？我怎样才能解决我的问题？我只是想在测验函数中播放所有问题一次。

答案 0 :(得分：0)
您可能希望将按钮创建/更新分离到将在while循环中调用的其他函数，因为除非它们在那里，否则它们将无法正确更新。或者，您可以尝试将测验（）转换为状态机。
答案 1 :(得分：0)
这是轮询事件队列并获取按键/按钮按下事件的函数：
events = pygame.event.get()
在while循环中，您提到此行永远不会被运行，因此事件不会被捕获。
此外，您不会致电clock.tick()
因此你必须在play_function中避免一段时间（在那里调用两个函数是反模式......它是正确的，它们只在主循环中被调用，所以将它们留在现在的位置）。分配一个状态变量并将play_function转换为仅执行循环的一次迭代的函数，返回主循环，您可以再次调用pygame.event.get()并让主循环执行所有循环。对于一个状态（你定义），主循环将再次调用play_function并检查这是否是第一次执行play_function，所以要执行或不执行＆＃34;当前的行＃＆＃ 34 ;.或者更好的是，除play_function，例如play_init和play_main，在2中处理单个州，如果要调用play_init或跳至play_main。

game_on = False

game_on = True;
