1.項目簡介
在剛剛學習完python套接字的時候做的一個五子棋小游戲，可以在局域網內雙人對戰，也可以和電腦對戰
2.實現思路
- 局域網對戰
對於局域網功能來說，首先建立連接（tcp），然后每次下棋時將棋子的坐標發送給對方，當接收到坐標后實例化成棋子對象，這個接收時用了select函數，因為pygame需要循環渲染圖片，所以要用非阻塞方式接收消息
select()的機制中提供一fd_set的數據結構，實際上是一long類型的數組， 每一個數組元素都能與一打開的文件句柄（不管是Socket句柄，還是其他文件或命名管道或設備句柄）建立聯系，建立聯系的工作由程序員完成， 當調用select()時，由內核根據IO狀態修改fd_set的內容，由此來通知執行了select()的進程哪一Socket或文件可讀或可寫，主要用於Socket通信當中
主要代碼如下：
1 # 接收cli的消息 2 if is_people: 3 rs, ws, es = select.select(inputs, [], [], 0) 4 for r in rs: 5 if r is tcpclisock: 6 try: 7 data = r.recv(BUFSIZ) 8 islink = True 9 print(data.decode('utf8')) 10 if data.decode('utf8') == 'again': 11 is_recieve1 = True 12 if data.decode('utf8') == 'yes': 13 is_playagain = True 14 is_play = True 15 if data.decode('utf8') == 'no': 16 is_recieve2 = True 17 islink = False 18 if not is_play and not result: 19 me = storn.Storn_Black(eval(data)) 20 black_chesses.append(me) 21 chesses.append(me) 22 is_play = True 23 except error: 24 islink = False
- 電腦對戰
電腦對戰的思路也很簡單，用了應該是最常見的也是最簡單的方法，就是循環遍歷棋盤的每一個點，判斷該點的價值，選取價值最大的點落子，這個需要對五子棋的棋型有一定了解，這里介紹幾種常見的棋型（約定1為己方棋子，2為對方棋子，0為空）
- 活四（011110）：這時候四顆棋子相連，同時兩端為空，已經阻止不了一方的勝利了，此時價值應該設置最高
- 死四（011112|10111|11011）：四顆棋子，只有一個地方能形成連五，如果是自己的棋可以贏，是對方的也可以阻止對方贏棋，此時價值次高
。。。
就這樣把每種棋型判斷一下，獲得該點的價值，主要代碼如下：
1 # 判斷每個點的價值 2 def point_value(pos, white_chesses, black_chesses, identify1, identify2): 3 value = 0 4 for i in range(1,9): 5 # *1111_ 活四 6 if get_point(pos, i, 1, white_chesses, black_chesses) == identify1 and \ 7 get_point(pos, i, 2, white_chesses, black_chesses) == identify1 and \ 8 get_point(pos, i, 3, white_chesses, black_chesses) == identify1 and \ 9 get_point(pos, i, 4, white_chesses, black_chesses) == identify1 and \ 10 get_point(pos, i, 5, white_chesses, black_chesses) == 0: 11 value += 40000 12 #

電腦選擇落子位置時，要判斷是進攻還是防守，需要兩次遍歷棋盤，獲取進攻時的最大價值和防守的最大價值，主要代碼如下：
1 # 電腦選取落子的位置 2 def ai(white_chesses, black_chesses, chesses): 3 value = max1 = max2 = 0 4 pos1 = pos2 = () 5 # 進攻時 6 for i in range(0,15): 7 row = 28 + i * 40 8 for j in range(0,15): 9 col = 28 + j * 40 10 pos = (row,col) 11 if is_empty(pos, chesses): 12 continue 13 value = point_value(pos, white_chesses, black_chesses, 1, 2) 14 if value > max1: 15 max1 = value 16 pos1 = (row,col) 17 18 # 防守時 19 for i in range(0,15): 20 for j in range(0,15): 21 row = 28 + i * 40 22 col = 28 + j * 40 23 if is_empty((row,col), chesses): 24 continue 25 value = point_value((row,col), white_chesses, black_chesses, 2, 1) 26 if value > max2: 27 max2 = value 28 pos2 = (row,col) 29 if max1 > max2: 30 return pos1 31 else: 32 return pos2
