本文为大家分享了pygame游戏之旅的第13篇，供大家参考，具体内容如下

定义暂停函数：

def paused():
 largeText = pygame.font.SysFont('comicsansms',115)
 TextSurf, TextRect = text_objects('Paused', largeText)
 TextRect.center = ((display_width/2),(display_height/2))
 gameDisplay.blit(TextSurf, TextRect)
 
 while pause:
  for event in pygame.event.get():
   print(event)
   if event.type == pygame.QUIT:
    pygame.quit()
    quit()
##  gameDisplay.fill(white)
  button("Continue", 150, 450, 100, 50, green, bright_green,game_loop)
  button("Quit",550, 450, 100, 50, red, bright_red,quitgame)
  pygame.display.update()
  clock.tick(15)

重新定义原来的crah函数：

def crash():
 largeText = pygame.font.SysFont('comicsansms',115)
 TextSurf, TextRect = text_objects('You Crashed!', largeText)
 TextRect.center = ((display_width/2),(display_height/2))
 gameDisplay.blit(TextSurf, TextRect)
 
 while True:
  for event in pygame.event.get():
   print(event)
   if event.type == pygame.QUIT:
    pygame.quit()
    quit()
##  gameDisplay.fill(white)
  button("Play Again", 150, 450, 100, 50, green, bright_green,game_loop)
  button("Quit",550, 450, 100, 50, red, bright_red,quitgame)
  pygame.display.update()
  clock.tick(15)
