我正在使用python为我的编程类制作游戏。当他们输球或退出比赛时，我不知道如何再次向玩家提供选项。我正在使用python 2.7。这是我游戏的代码：

pygame.display.set_caption('Dankest Memes')
# set up the colors

游戏很简单。玩家四处移动，收集食物以获得积分并避免坏人，这样他们就不会失分。当分数低于0时，玩家输了。我设法得到并结束了游戏画面，但在此之后我无法再次播放或退出游戏。
答案 0 :(得分：1)
首先，一个建议。如果你向他们展示你尝试过的东西，人们就更有可能帮助你。
无论如何。
我要做的是将整个游戏循环包裹在一个函数中。像这样：
$ git push --force origin <branch name>
接下来当你的游戏结束时（我假设它确实具有使其结束的条件），通过屏幕功能调用游戏。在您的游戏结束屏幕功能中，您可以首先用一种颜色填充窗口，然后将任何文本blit到您要向用户显示的屏幕上，例如＆＃34;按任意键再次播放＆＃34;。然后你会检查是否按下了任何键，如果是，则调用游戏循环功能。您还需要检查用户是否正在尝试关闭窗口。
然后通过屏幕功能调用游戏：
def game_loop():
while True:
# check for the QUIT event
for event in pygame.event.get():
if event.type == QUIT:
pygame.quit()
sys.exit()
....
