python网络编程案例——五子棋游戏pythonqq44176343的博客-

一.本案例基于UDP的socket编程方法来制作五子棋程序，网络五子棋采用C/S架构，分为服务器端和客户端，游戏时服务端首先启动，当客户端启动连接后，服务器端可以走棋，轮到自己棋才可以在棋盘上落子，同时下方标签会显示对方走起信息，服务器端用户可以通过“退出游戏”按钮可以结束游戏；

1.数据通信协议

网络五子棋游戏设计的难点在于对方进行通信，这里使用面向非连接的Socket编程，Socket编程用于C/S开发，在这类应用中，客户端和服务器端通常需要先建立连接，然后发送和接收数据，交互完成后需要断开连接，本章采用基于UDP的Socket编程实现，这里虽然两台计算机不分主次，但涉及时候假设一台作为服务器端，等待其他方加入，其他想加入必须输入服务器端主机的IP；
下面展示一些 数据通信协议代码。

def receiveMessage():     global s     while True:         global addr         data,addr=s.recvfrom(1024)         data=data.decode('utf-8')         a=data.split("|") if not data: print("client has exited!") break         elif a[0]=='join':  #连接服务器请求             print('client 连接服务器！')             label1["text"]='client连接服务器成功，请你走棋！'         elif a[0]=='exit': print('client 对方退出！')             label1["text"]='client对方退出，游戏结束！'         elif a[0]=='over': print('对方赢信息！')             label1["text"]=data.split("|")[0] showinfo(title="提示",message=data.split("|")[1])         elif a[0]=='move': print('received:',data,'from',addr)             p=a[1].split(",")             x=int(p[0])             y=int(p[1]) print(p[0],p[1])             label1["text"]="客户端走的位置"+p[0]+p[1] drawOtherChess(x,y)     s.close() 

2.判断输赢的算法

   本游戏关键技术就是判断输赢的算法，对于算法实现大致可以分为以下几个部分： 

（1）判断X=Y轴上是否形成五子连珠；

（2）判断X=-Y轴上是否形成五子连珠；

（3）判断X轴上是否形成五子连珠；

（4）判断Y轴上是否形成五子连珠；

#输赢判断 def win_lose():     a=str(turn) print("a=",a) for i in range(0,11): for j in range(0,11): if map[i][j]==a and map[i+1][j+1]==a and map[i+2][j+2]==a and map[i+3][j+3]==a and map[i+4][j+4]==a: print("x=y轴上形成五子连珠") return True     for i in range(4,15): for j in range(0,11): if map[i][j]==a and map[i-1][j+1]==a and map[i-2][j+2]==a and map[i-3][j+3]==a and map[i-4][j+4]==a: print("x=-y轴上形成五子连珠") return True     for i in range(0,15): for j in range(4,15): if map[i][j]==a and map[i][j-1]==a and map[i][j-2]==a and map[i][j-2]==a and map[i][j-4]==a: print("Y轴上形成了五子连珠") return True     for i in range(0,11): for j in range(0,15): if map[i][j]==a and map[i+1][j]==a and map[i+2][j]==a and map[i+3][j]==a and map[i+4][j]==a: print("X轴形成五子连珠") return True     return False
