游戏规则:
1.将/帅:不能出田字格,不能走斜线,只能前进后退向左向右,每次只走一格;
2.士/仕:不能出田字格,只能走斜线,每次只走一格;
3.象/相:只能走田字格,中间防止蹩脚,不能有棋;
4.马:只能走日,(这个比较麻烦,且看下图标识)
5.车:车只能走直线,这个很好理解,不细说了;
6.炮:
情况一:纯走路—->中间和目的地都不能有棋 情况二:吃棋—–>中间要有一颗棋,目标也有棋,且是敌方的棋,毕竟不能自己吃自己哈
7.卒/兵:
河这边:只能前进不能后退,不能横着走!!! 河对面:可以前进,可以横着走,不能后退!!!
面板设计
看上去一定很挫!哈哈,别急,听我细细道来! 一般的界面设计我们都知道横纵坐标是这样的:
但是我选择背道而行,不是因为别的,是为了更好的去让初学者理解,我们把原本的x坐标看成数组的列(col),把y坐标看成我们数组的行(row),这样是不是更好理解一点呢,当然了我就是这么理解的,哈哈,接下来的游戏代码编程我们会把横坐标用y*width,纵坐标用x*height你们应该就能理解为什么了,因为x是数组的行,也就是坐标纵坐标(y)的体现,同理数组中的y也是如此。
数据传输:这里我们采用UDP协议来进行通讯,所以你们也要先去了解一下UDP协议的一些基本方法,这里就不细讲了。
通讯协议:这里我们自定义通讯协议啊: “play|”——–以此开头代表一端发出了游戏邀请,等待另一端的回应; “connect|”——-以此开头代表另一端收到邀请并且同意建立连接通讯!如果邀请者受到这条消息就代表通讯建立成功,可以开始游戏了; “move|”——以此开头代表移动数据传输,如果一端移动了棋子,那么另一端也要收到信息,重新绘制界面; “lose|”——–以此开头代表一方认输,如果有一方认输就会向另一方发送该信息; “quit|”——-以此开头代表一方退出游戏,任意一方离开都会向对方发送该信息,以提示对方; “success|”—–以此开头代表胜利,某一方胜利就向对方发出信息,通知对方; “regret|”——以此开头表示悔棋,这个不用讲了吧,大家都明白,但是本次编程中我没有把这个加进去,这个你们可以自己根据自己需要去添加。 (肯定有人问我这个协议是谁定义的,啊哈哈,让你们失望了,这是我自己定义的,这个通讯协议只适用于你们写的这个代码,和使用这个代码的两个人通讯使用,所以协议如何自己可以定义的哦)
