1.项目简介
在刚刚学习完python套接字的时候做的一个五子棋小游戏，可以在局域网内双人对战，也可以和电脑对战
2.实现思路
- 局域网对战
对于局域网功能来说，首先建立连接（tcp），然后每次下棋时将棋子的坐标发送给对方，当接收到坐标后实例化成棋子对象，这个接收时用了select函数，因为pygame需要循环渲染图片，所以要用非阻塞方式接收消息
select()的机制中提供一fd_set的数据结构，实际上是一long类型的数组， 每一个数组元素都能与一打开的文件句柄（不管是Socket句柄，还是其他文件或命名管道或设备句柄）建立联系，建立联系的工作由程序员完成， 当调用select()时，由内核根据IO状态修改fd_set的内容，由此来通知执行了select()的进程哪一Socket或文件可读或可写，主要用于Socket通信当中
主要代码如下：
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
- 电脑对战
电脑对战的思路也很简单，用了应该是最常见的也是最简单的方法，就是循环遍历棋盘的每一个点，判断该点的价值，选取价值最大的点落子，这个需要对五子棋的棋型有一定了解，这里介绍几种常见的棋型（约定1为己方棋子，2为对方棋子，0为空）
- 活四（011110）：这时候四颗棋子相连，同时两端为空，已经阻止不了一方的胜利了，此时价值应该设置最高
- 死四（011112|10111|11011）：四颗棋子，只有一个地方能形成连五，如果是自己的棋可以赢，是对方的也可以阻止对方赢棋，此时价值次高
。。。
就这样把每种棋型判断一下，获得该点的价值，主要代码如下：
1 # 判断每个点的价值 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 #

电脑选择落子位置时，要判断是进攻还是防守，需要两次遍历棋盘，获取进攻时的最大价值和防守的最大价值，主要代码如下：
1 # 电脑选取落子的位置 2 def ai(white_chesses, black_chesses, chesses): 3 value = max1 = max2 = 0 4 pos1 = pos2 = () 5 # 进攻时 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 # 防守时 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 pos2View Code
