1) 开局,你是什么颜色
2)选择棋子,
3)走棋
4)悔棋(悔棋悔两步)
5)认输
网络实现:
1)建立连接
a.主机,建立监听socket
b.accept
c.关闭监听socket
a.客户端,连接服务器
2)发送报文
1)服务器给客户端发送开局报文
2)选棋 发送选棋报文
3)走棋 发送走棋报文
4)悔棋
5)认输 重新开始
报文格式定义:
第一个字节表示命令字 0表示开具,1表示选其,2表示走棋,3表示悔棋,4表示认输
开局报文 [0][0或者1] 收到0表示走黑棋,收到1表示走红旗 [0][0] [0][1]
选棋报文 [1][0~31]
走棋报文 [2][0~31][x][y] x和y已经转换好的
悔棋 [3]
认输 [4][0或者1]
运行时设计
定义一个全局变量 char packet[4]用来保存报文
定义一个定时器,每秒去收socket
