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)
