本文为大家分享了pygame游戏之旅的第6篇，供大家参考，具体内容如下
定义一个障碍模型函数：
|
1
2
|
def things(thingx, thingy, thingw, thingh, color): pygame.draw.rect(gamedisplay, color, [thingx, thingy, thingw, thingh]) |
在游戏循环中调用：
|
1
2
|
things(thing_startx, thing_starty, thing_width, thing_height, black)thing_starty += thing_speed |
障碍消失之后修改x值：
|
1
2
3
|
if thing_starty > display_height: thing_starty = 0 - thing_height thing_startx = random.randrange(0, display_width) |
