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()
