python網(wǎng)絡(luò)編程之五子棋游戲

這篇文章主要為大家詳細(xì)介紹了python網(wǎng)絡(luò)編程之五子棋游戲，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

一.本案例基于UDP的socket編程方法來制作五子棋程序，網(wǎng)絡(luò)五子棋采用C/S架構(gòu)，分為服務(wù)器端和客戶端，游戲時服務(wù)端首先啟動，當(dāng)客戶端啟動連接后，服務(wù)器端可以走棋，輪到自己棋才可以在棋盤上落子，同時下方標(biāo)簽會顯示對方走起信息，服務(wù)器端用戶可以通過“退出游戲”按鈕可以結(jié)束游戲；

1.數(shù)據(jù)通信協(xié)議

網(wǎng)絡(luò)五子棋游戲設(shè)計的難點(diǎn)在于對方進(jìn)行通信，這里使用面向非連接的Socket編程，Socket編程用于C/S開發(fā)，在這類應(yīng)用中，客戶端和服務(wù)器端通常需要先建立連接，然后發(fā)送和接收數(shù)據(jù)，交互完成后需要斷開連接，本章采用基于UDP的Socket編程實現(xiàn)，這里雖然兩臺計算機(jī)不分主次，但涉及時候假設(shè)一臺作為服務(wù)器端，等待其他方加入，其他想加入必須輸入服務(wù)器端主機(jī)的IP；

下面展示一些數(shù)據(jù)通信協(xié)議代碼。

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': #連接服務(wù)器請求
 print('client 連接服務(wù)器！')
 label1["text"]='client連接服務(wù)器成功，請你走棋！'
 elif a[0]=='exit':
 print('client 對方退出！')
 label1["text"]='client對方退出，游戲結(jié)束！'
 elif a[0]=='over':
 print('對方贏信息！')
 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"]="客戶端走的位置"+p[0]+p[1]
 drawOtherChess(x,y)
 s.close()

2.判斷輸贏的算法

本游戲關(guān)鍵技術(shù)就是判斷輸贏的算法，對于算法實現(xiàn)大致可以分為以下幾個部分：

（1）判斷X=Y軸上是否形成五子連珠；

（2）判斷X=-Y軸上是否形成五子連珠；

（3）判斷X軸上是否形成五子連珠；

（4）判斷Y軸上是否形成五子連珠；

#輸贏判斷
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軸上形成五子連珠")
 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軸上形成五子連珠")
 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軸上形成了五子連珠")
 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軸形成五子連珠")
 return True
 return False
