C/C++实现经典象棋游戏的示例代码
作者：风光无限，未必快乐
中国象棋是起源于中国的一种棋，属于二人对抗性游戏的一种，在中国有着悠久的历史。本文将利用C++实现这一经典游戏，快跟随小编一起学习一下吧
大体思路
采用面相过程的设计方式实现，类似于我们平时做的课程设计，实现这样的小游戏无非就是多了图形处理库。这里使用的是acllib图形库。
设计这种小游戏，首先要从宏观上去认识：象棋，要有棋盘，要有棋子，棋子要移动。
对于棋盘，十行九列画出即可。
对于棋子，分黑红两方，按照指定位置画出。
如何移动棋子，我们有mouseEvent函数。
初始化棋盘棋子：initmap，initpaint
利用鼠标实现棋子移动分两步(mouseEvent)：
第一次点击，记录点击棋子的信息
第二次点击，将第一次点击记录的棋子信息移动到第二次点击的位置。
最后在添加亿点细节。
- 首先画棋盘——chessboard（）
- 初始化棋子信息——initmp（）
- 将棋子画到棋盘上——initpaint（）
- 注册鼠标，通过鼠标点击不同位置实现棋子的移动（按照象棋行棋规范）——mouseEvent（int x, int y, int button, int e）x、y为点击位置，button（鼠标左右键与滑轮）、e（点击或抬起）为事件。
- 行棋规范——judge_piece(int x, int y)代表能否从上一步走到x,y处。
此外，实现象棋必然缺不了人机对战。对于人机算法我们可以采用最简单的遍历。每次遍历获取所有人机方棋子能走的地方，然后根据评估函数找出这些步中对人机方来说收益最大的一步。思路很简单，但是想写出走一步看很多步的算法也很难。首先评估函数要尽量具有代表性，这直接决定了人机的棋力；其次需要迭代遍历，这样次数多了时间复杂度就会很高。
这里只写了走一步看一步的人机代码供参考，更深入的可以自行去了解：
1、void Get_All_path()——获取人机所有可能走的方式（将step存入向量v中）
2、int calculate_value()——评估函数
3、void Get_max_way()——得到对人机最有利的那一步（传到prex，prey与nowx，nowy中，即从pre走到now）。
