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
BACKGROUNDCOLOR = (255, 255, 255)
BLUE = (0, 0, 255)
BLACK = (0, 0, 0)
FPS = 40
VHNUMS = 3
CELLNUMS = VHNUMS*VHNUMS
MAXRANDTIME = 100
# 退出
def terminate():
 pygame.quit()
 sys.exit()
# 随机生成游戏盘面
def newGameBoard():
 board = []
 for i in range(CELLNUMS):
   board.append(i)
 blackCell = CELLNUMS-1
 board[blackCell] = -1
 for i in range(MAXRANDTIME):
   direction = random.randint(0, 3)
   if (direction == 0):
     blackCell = moveLeft(board, blackCell)
   elif (direction == 1):
     blackCell = moveRight(board, blackCell)
   elif (direction == 2):
     blackCell = moveUp(board, blackCell)
   elif (direction == 3):
     blackCell = moveDown(board, blackCell)
 return board, blackCell
# 若空白图像块不在最左边，则将空白块左边的块移动到空白块位置
def moveRight(board, blackCell):
 if blackCell ％ VHNUMS == 0:
   return blackCell
