当玩家失去但没有任何东西出现并且游戏立即重新启动时，我试图制作一些文本显示。它可以到达else语句，因为它能够打印东西，但它似乎没有“blit”表面，或者它可以快速查看。
有问题的代码盯着底部，但我想我也会包含主要功能。我不知道我是否正确，但它是否在绘制后立即在文本框中绘制背景？如果是这样，我该如何解决这个问题呢？

答案 0 :(得分：2)
您正在绘制游戏结束文本，但直到循环重新开始之前才更新显示（因此游戏结束文本可能仅渲染1帧）。尝试这样的事情：
else:
# game is over, show "game over" text
gameOverStartTime = time.time()
DISPLAYSURF.blit(gameOverSurf, gameOverRect)
pygame.display.update()
print (gameOverMode)
while time.time() - gameOverStartTime < GAMEOVERTIME:
pass
这将绘制游戏结束文本，更新屏幕，然后循环，直到超过GAMEOVERTIME定义的时间量（我认为你实际上并没有在任何地方做，至少不在您发布的代码中）。请注意，我给你的这个循环不允许你处理任何输入事件或任何事情，直到分配的时间到期，但它将保证游戏结束文本将在你的时间内呈现给屏幕想。
