我的退出按钮在我的pygame中有效，但仅部分起作用。一旦我刚运行了游戏，它就会起作用，但是当我在游戏中被杀死并且将game_loop重置后，退出按钮只会在我按下它时重置游戏循环，并且不会关闭窗口。好像已经改变了它的功能，使其与玩家被杀死的功能相同。
我将向您展示我的整个游戏代码，以使其变得更容易。 （顺便说一下，我的游戏目前正在更改，因此某些地方可能放置在错误的位置，而别担心。）

这意味着分配您可以在我的代码中找到错误。 如果您还有其他问题，请让我知道。
答案 0 :(得分：0)
这里的代码有点错误。在while True:循环中尝试以下操作：
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
pygame.display.update()
[{The pygame.display.update”位在其他位置，因此请将其删除，然后复制并粘贴到istead中。]
