C/C++:实现象棋游戏

  • 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)。
