本文为大家分享了pygame游戏之旅的第8篇，供大家参考，具体内容如下
定义一个计数函数：
|
1
2
3
4
|
def things_dodged(count): font = pygame.font.sysfont(none, 25) text = font.render("dodged:"+str(count), true, black) gamedisplay.blit(text,(0,0)) |
在游戏循环中加入计数，然后增加一些游戏难度，例如加速障碍，增加障碍的宽度：
|
1
2
3
|
dodged += 1thing_speed += 1thing_width += (dodged * 1.2) |
