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)
