pygame游戏之旅 添加游戏暂停功能

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)
