游戏老虎吃绵羊 -- lua_老虎吃羊的棋盘图-优快云博客

本文链接：https://blog.youkuaiyun.com/piaobotudou/article/details/38390773

简介:

游戏双方分别使用绵羊（S）和老虎(T)

图 1
图中6S代表当前为位置上有6只绵羊

除了如图所示为6S的点外，其他点只能同时有一个动物，6S点可容纳任意数量的动物，但必须是同一种类，两只老虎不能同时出现在同一位置上

绵羊每次可以沿着连线移动一个位置，老虎每次也可以仅移动一个位置，但如果该直线方向上相邻是绵羊，且距离为2的点为空时，老虎可以跨过绵羊跳到该位置，并吃掉绵羊

当绵羊数为0时老虎胜，老虎无法移动时绵羊胜，如图2，(3, 2)位置上的老虎跳到(5, 2)吃掉（4，2）上的一只绵羊

图 2

绵羊和老虎轮流移动一个棋子，每局开始以如图1所示开始，且老虎先走。

游戏操作:

提示：It's turn to tigger

输入：老虎所在行（回车）老虎所在列(回车)

提示: Input move target

输入：要移动到的位置行(回车)，列（回车）

完成后切换到羊

提示： It's turn to sheep

输入：羊所在行(回车)，列（回车）

如果该位置有多只羊

提示Select piece,并列出该位置上羊的索引如1 2 3 4 5 6

输入：羊的索引，如1（回车）

提示：Input move target

输入：要移动到的位置行(回车)，列（回车）

完成羊的移动，切换到老虎，交换操作直到游戏结束，如

Sheep win
