上篇我们对python的Socket编程有了一个基本的认识，接下来就可以完成五子棋的网络对战的实现。步骤如下：1、服务端开始侦听2、客户端通过tcp连接上服务端，开局3、判断输赢后，一方提出是否开新局4、对方同意后，开新局。接下来就简单了，只要把Socket编程的通信部分弄到以前的代码就可以了。五子棋人机对战版：（https://blog.csdn.net/cxhold/article/details/140126002https://blog.csdn.net/cxhold/article/details/140133224https://blog.csdn.net/cxhold/article/details/140136176https://blog.csdn.net/cxhold/article/details/140142940https://blog.csdn.net/cxhold/article/details/140159258）五子棋人机代码三、代码结构：服务端和客户端的代码区别就在main.py中3.1服务端main.py# encoding:utf-8 import pygame from pygame.locals import * import sys import os from socket import * import select import piece from tkinter import * from params import Params from utils import * pygame.init() pygame.mixer.init() WHITE = (255, 255, 255) BLACK = (0, 0, 0) rows = int(Params.get('ROWS')) blocksize = int(Params.get('blockSize')) width = int(Params.get('WIDTH')) height = int(Params.get('HEIGHT')) game_bgsize = width, height # 棋盘 x = [] #x轴 y = [] #y轴 for i in range(0, rows): #棋盘的所有交叉点坐标(x,y) x.append(28 + i * blocksize) y.append(28 + i * blocksize) # 记录棋盘每个坐标的属性，没有棋子为0，白棋为1，黑棋为2 chess_map = {} #结构是chess_map[28,28] = 0 ... # 字体 fontpath = os.path.join(Params.get('resourcePath'), Params.get('fontFolder'), 'simkai.ttf') myfont = pygame.font.Font(fontpath, 38) # 起始选项 txtplayerandplayer = myfont.render("玩家与玩家", True, WHITE) txtplayerandplayer_rect = txtplayerandplayer.get_rect() txtplayerandplayer_rect.left, txtplayerandplayer_rect.top = (game_bgsize[0] -
