童年记忆第七弹！！！用python开发2048

###前言
这款游戏的玩法很简单，每次可以选择上下左右滑动，每滑动一次，所有的数字方块都会往滑动的方向靠拢，系统也会在空白的地方乱数出现一个数字方块，相同数字的方块在靠拢、相撞时会相加。不断的叠加最终拼凑出2048这个数字就算成功。

2048的规则大家都清楚了，那么我们一起来用python开发它吧。

游戏效果

游戏用到的图片

数字图片都是90像素的正方形

游戏代码

[2048.py]（游戏主模块）

import pygame
from settings import Settings
import game_body as gb
import 算法 as sf

nums = [[0, 0, 0, 0],
        [0, 0, 0, 0],
        [0, 0, 0, 0],
        [0, 0, 0, 0]]
def run_game():
    set = Settings()
    pygame.init()
    screen = pygame.display.set_mode((set.screen_width, set.screen_height))
    pygame.display.set_caption("2048")
    sf.addnum(nums)
    sf.addnum(nums)
    while True:
        gb.check_events(nums)
        gb.update_screen(nums, set, screen)
        pygame.display.flip()
run_game()

[算法.py]对应按键的数据处理，判断游戏是否结束，添加数字）

对数据的处理没有好好想更好的处理方法，我觉着肯定有简单的方法，但是我想不到。。。
