Python2048小游戏

　　在一本书上找到的小游戏实例,自己运行起来感觉比较有意思就发出来看看.
　　其中有很多地方不是很懂,等到自己研究透彻了会更新带全部注释版本的.
　　对于pygame模块还是在探索阶段,大家要有什么好的学习渠道可以在评论区留言,不胜感谢import random  import pygame import time import sys from pygame.locals import * import threading  # 多线程模块  SIZE = 4  # 2048的小格式4*4,尺寸暂定为4 LENGTH = 130  # 每个小格的边长长度 SCORE_HEIGTH = 130   # 计分区占用高度  DEFAULT = (205, 193, 180)  # 背景颜色 C_FONT = (120, 111, 102)  # 字体颜色 C_2 = (238, 228, 218) C_4 = (237, 224, 200) C_8 = (242, 177, 121) C_16 = (245, 149, 99) C_32 = (246, 94, 59) C_64 = (246, 94, 59) C_128 = (237, 207, 114) C_256 = (237, 204, 98) C_512 = (237, 200, 80) C_1024 = (237, 197, 63) C_2048 = (225, 187, 0)  ＂＂＂ 建立获取颜色的函数 ＂＂＂   def get_color(n):     n_t = 0     for i in range(1, 12):         if n >> i == 1:             n_t = i     color = [         DEFAULT,         C_2,         C_4,         C_8,         C_16,         C_32,         C_64,         C_128,         C_256,         C_512,         C_1024,         C_2048,         C_FONT]     return color[n_t]   ＂＂＂ 画面内容控制 ＂＂＂   class Map:     def __init__(self, size):         self.size = size         self.map = [[0 for i in range(size)]for i in range(size)]         self.score = 0         self.is_move = 0         self.add()         self.add()      def add(self):         while True:             pos = random.randint(0, self.size * self.size -
