如何解决当我点击游戏中的项目时，Pygame 无法识别我的鼠标

shop()
在 shop() 中，我希望它能够识别何时有人点击了某个物品（手枪、步枪等），但每当我点击它时，什么都没有发生。
希望这些细节足以让你们解决我的问题。
谢谢！
ps。此代码未完成。因此，如果您想知道为什么代码中有一些奇怪的东西，很可能是为了稍后在项目中使用。
解决方法
我正在努力理解您的代码背后的逻辑，但问题是由于您多次调用 pygame.event.get() 而引起的。它无处不在。有时您正在调用它，甚至不存储它，这又可能不是您想要的。在您的主循环中，调用一次并存储它。
while running:
events = pygame.event.get()
for event in events:
#do stuff with it
然后要访问 shop 中的事件，将事件作为参数 def shop(events) 并使用此 events 变量而不是 pygame.event.get()。
然后在主循环中，当您调用 shop 时，将事件作为参数传递。
if spot[0] < 240 and spot[0] > 90 and spot[1] > 15 and spot[1] < 85:
shop(events)
您还多次调用 pygame.display.update()，这可能会导致闪烁问题。
