Nine men morris游戏C ++ [英] Nine mens morris game C++
本文介绍了Nine men morris游戏C ++的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个练习，我需要练习Nine Mens Morris游戏
我需要帮助在游戏中找到有效序列的算法
目前我已经实施了游戏板，将棋子插入棋盘并找到了邻居（虽然我也很乐意提出优化建议。）
创建序列的目标是，如果玩家X的长度和宽度（不是对角线）有三个序列，那么X可以选择一个他可以从中移除的Y玩家游戏
它没有完成，有点乱我知道它
这就是我安排好的桌子

每个
磨坊我附近他的邻居
问题是：如何即时通讯请求sequnce搜索？
我遇到问题的功能是rules.Cpp：
I have an exercise where I need to exercise the Nine Mens Morris game
And I need help with the algorithm of finding valid sequences in the game
For the time being i've implemented the board of the game, inserting pieces to the board and finding the neighbors (although in an elegant way that too I would have been happy to propose optimization.)
The goal in creating sequences is that if player X has a sequence of three pieces in length and width (not diagonally) then X can select a piece of Y player that he can remove from the game
it's not finished and kind of messy i know it
this is how i arranged the table

for each mill i attached his neighbours
The question is:How to implement the sequnce search?
the function that I have problem with is in "rules.Cpp" :
bool check_if_trio(int row,int col, Board& b,char player);
我尝试过：
board.h
What I have tried:
board.h

You must solve the problems by using the debugger. In the tutorial Learn C++ Chapter 1.11 and follow are the techniques how to use the debugger explained. Watch the memory of your neighbours array to see what is happening.
Tip: I am convinced that your set_neighbour() function isnt optimal. I would write some set_mill() functions.
