Python Pygame.time.set_time，我想让它在特定点发生

我试图使

pygame.time.set_time（）

仅在

单击后运行。我曾尝试将pygame.time.set_time放在if语句中，但没有成功。非常感谢您的回复！将计时器启动置于
MOUSEBUTTONDOWN
事件中时，它将仅在单击鼠标时启动，但每次单击时它都会重置。
单击在何处递增？在这段代码中它没有改变。我添加了程序的所有代码。我添加了一个timer_on变量和一个if来测试它。如果未设置，计时器将启动。请看下面。因此，出现的问题是，每次我单击时，计时器都会重置。在下面，它显示gameExit=True添加pygame.time.set_timer（ENDTIMER，0）和timed=pygame.time.set_timer（ENDTIMER，1000）添加timer_on=True。请将答案标记为正确！！谢谢很高兴它有帮助！
