一.本案例基於UDP的socket編程方法來製作五子棋程序，網絡五子棋採用C/S架構，分爲服務器端和客戶端，遊戲時服務端首先啓動，當客戶端啓動連接後，服務器端可以走棋，輪到自己棋纔可以在棋盤上落子，同時下方標籤會顯示對方走起信息，服務器端用戶可以通過“退出遊戲”按鈕可以結束遊戲；
1.數據通信協議
網絡五子棋遊戲設計的難點在於對方進行通信，這裏使用面向非連接的Socket編程，Socket編程用於C/S開發，在這類應用中，客戶端和服務器端通常需要先建立連接，然後發送和接收數據，交互完成後需要斷開連接，本章採用基於UDP的Socket編程實現，這裏雖然兩臺計算機不分主次，但涉及時候假設一臺作爲服務器端，等待其他方加入，其他想加入必須輸入服務器端主機的IP；
下面展示一些 數據通信協議代碼。
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': #連接服務器請求
print('client 連接服務器！')
label1["text"]='client連接服務器成功，請你走棋！'
elif a[0]=='exit':
print('client 對方退出！')
label1["text"]='client對方退出，遊戲結束！'
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
本遊戲關鍵技術就是判斷輸贏的算法，對於算法實現大致可以分爲以下幾個部分：
（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
