Python加pyGame实现的简单拼图游戏实例

本文实例讲述了Python加pyGame实现的简单拼图游戏。分享给大家供大家参考。具体实现方法如下：

    import pygame, sys, random
    from pygame.locals import *
    # 一些常量
    WINDOWWIDTH = 500
    WINDOWHEIGHT = 500

    BLACK = (0, 0, 0)

    MAXRANDTIME = 100
    # 退出
    def terminate():
      pygame.quit()
      sys.exit()
    # 随机生成游戏盘面

          blackCell = moveUp(board, blackCell)
