本例子需要使用已安装pygame的python才能运行

#!/usr/bin/env python

    redColour = pygame.Color(255,0,0)

    # 定义gameOver函数
    def gameOver(playSurface):

        gameOverSurf = gameOverFont.render('Game Over', True, greyColour)
        gameOverRect = gameOverSurf.get_rect()
        gameOverRect.midtop = (320, 10)
        playSurface.blit(gameOverSurf, gameOverRect)
        pygame.display.flip()
        time.sleep(5)
