话说这游戏中文名叫什么来着，死活想不起来了，算了话不多说，140行实现小游戏系列第二章，依然是简单小游戏，与数独游戏相比，在游戏界面显示上更难一些，但是在逻辑方面更简单一些，需要处理的无非是速度、加速度、时间、位置、碰撞检测，界面方面则要实现整个动态的显示；
依旧在最后会给出全部代码，不过依然可以从我的Github仓库Fork下来直接运行，图片资源也在那里，have fun.
运行以及玩法：
后续扩展：
可以看到对于这个游戏，实际上移动的是管道而不是小鸟，因此这里主要是处理管道绘制的位置变化，以及整个一个循环的过程，如果屏幕上显示的管道是N个，那么可以想象是N+2个管道在不停地转圈圈出现在我们的界面上就行了；
tunnel_list = [x-speed if x-speed>-200 else 2100 for x in tunnel_list ]
def draw_tunnel():
for x in tunnel_list:
pygame.draw.rect(screen,COLORS[‘darkgreen‘],(x,0,100,350),0)
pygame.draw.rect(screen,COLORS[‘darkgreen‘],(x+100,550,100,350),0)
不操作的情况下，小鸟的上下移动是做自由落体，也就是越来越快的下降的过程，而当我们点击空格进行跳跃后，实际上改变的就是小鸟的当前速度，因此小鸟会向上越来越慢的跳跃，直到速度为0后，继续下降，符合基本的物理规则；
G = 9.8*30 # g
JUMP_V = -300
bird_x,bird_y = 700,450
bird_v = 0
if not jump:
bird_v += G*frame
else:
bird_v = JUMP_V
jump = False
bird_y += frame*bird_v
def draw_bird():
screen.blit(birdImg,[bird_x,bird_y])
检测小鸟是否碰到管道或者是掉到地上，这么说是只无脚鸟咯，实际上就是检测两个矩形是否有重叠的部分；
def rect_cover(rect1,rect2,up=True):
# bird
left_up1 = (rect1[0],rect1[1])
left_down1 = (rect1[0],left_up1[1]+rect1[3])
right_up1 = (left_up1[0]+rect1[2],rect1[1])
right_down1 = (left_up1[0]+rect1[2],left_up1[1]+rect1[3])
# tunnel
left_up2 = (rect2[0],rect2[1])
left_down2 = (rect2[0],left_up2[1]+rect2[3])
right_up2 = (left_up2[0]+rect2[2],rect2[1])
right_down2 = (left_up2[0]+rect2[2],left_up2[1]+rect2[3])
# check
if (left_up2[0]<=right_up1[0]<=right_up2[0]): # x,肯定是右侧线接触，因此判断bird的right即可
if up and (left_up2[1]<=right_up1[1]<=left_down2[1]):
return True
elif (not up) and (left_up2[1]<=right_down1[1]<=left_down2[1]):
return True
return False
看到，实际上是借助了Surface，将其设置为想要的透明度后blit到我们的screen上即可，直接draw rect是不支持RGBA的A设置alpha的，不知道为啥这么坑爹的设计；

数独和FlippyBird都在这里，欢迎大家Fork下来直接运行，后续会不定期更新其他小游戏，目前以简单的动作小游戏、棋牌类为主，想到啥做啥，或者大家有什么想做想玩的可以评论区告诉我哈，搞得定的我会尽快完成；
大家可以到我的Github上看看有没有其他需要的东西，目前主要是自己做的机器学习项目、Python各种脚本工具、有意思的小项目以及Follow的大佬、Fork的项目等：
