你能给我的任何帮助都会很棒。我正在使用python中的简单游戏。我想在屏幕上运行一个倒数计时器。根据本网站上回答的其他问题，我认为我的代码大多是正确的，我遇到的问题是我使用“for”循环运行定时器代码。我不太确定为什么它现在不适合我，当我运行游戏时，我没有得到任何错误，倒计时显示但它只倒计时一秒而且它坚持这一次（01:29 ）。任何建议都会非常感激。我正在努力的代码是在游戏的主循环（第354行）中名为“”“Timer Countdown”“”的部分中的程序结束。非常感谢。

答案 0 :(得分：1)
使用pygame.time.get_ticks（）存储开始时间， 再次调用此帧将给出比存储的开始时间更长的时间，只需从此减去开始时间以获得自计时器启动以来的毫秒间隔
正如@jonrsharpe所说，它应该是一个代码＆＃34;样本＆＃34;，而不是整个sodding的东西，因此我可能没有真正回答你的问题，我不能告诉因为我＆＃ 39;我不会阅读和理解整个代码。
