c#实现中国像棋的开发笔记
最近，和朋友下象棋，然后想到这个多年陈旧的代码（这些代码有些参考了网络的一些帖子），曾经因为不知道如何实现人机对战而放弃继续研究。如今，这位朋友，给了我又重新找回来的兴趣，所以来这里请大家帮忙，如何实现人机对战，让电脑自动下呢？
当前，已经完成黑、红两方的下棋规则，但是还没有实现人机对战，目前只能人人对战，也就是说一个具有下棋规则的棋盘而已。
为了方便大家给我出招解惑，我先说一下自己程序的原理：
1， 32个棋子都是具体的类，并都是继承于ChessWorldBase。
棋子基类
using System;
using System.Collections;
using System.Windows.Forms;
namespace Zivsoft.Business.Chess
{
/// <summary>
/// 棋子
/// </summary>
internal abstract class ChessWordBase:IChess
{
public const int XBoardLength = 9;
public const int YBoardLength = 10;
public static ArrayList All = new ArrayList();
/// <summary>
/// 棋盘范围内
/// </summary>
/// <returns></returns>
public virtual bool Check()
{
if ((this.X > 9) || (this.X < 1))
{
return false;
}
if ((this.Y > 10) || (this.Y < 1))
{
return false;
}
return true;
}
/// <summary>
/// 被吃掉
/// </summary>
public virtual void Destroy()
{
this.IsDogFall = false;
this.X = 0;
this.Y = 0;
}
public virtual void Init()
{
this.IsDogFall = true;
this.X = 0;
this.Y = 0;
}
#region IChess Members
/// <summary>
///
/// </summary>
public bool IsRedChess
{
get;
set;
}
/// <summary>
///
/// </summary>
public bool IsDogFall
{
get;
set;
}
/// <summary>
/// 进攻
/// </summary>
public bool IsAttack
{
get;
set;
}
public int NextX
{
get;
set;
}
public int NextY
{
get;
set;
}
public int X
{
get;
set;
}
public int Y
{
get;
set;
}
/// <summary>
///
/// </summary>
public string Name
{
get;
set;
}
public abstract ArrayList GetNextLocation();
public void Move(int ix,int iy)
{
this.MoveNext();
if (this.Check(ix, iy, GetNextLocation()))
{
X = ix;
Y = iy;
}
}
private void MoveNext()
{
this.NextX = this.X;
this.NextY = this.Y;
}
public abstract bool Check(int x, int y, ArrayList al);
public void Move(int iX, int iY, object qz)
{
if (qz == null)
{
this.Move(iX, iY);
}
else
{
this.MoveNext();
if (this.Check(iX, iY, GetNextLocation()))
{
X = iX;
Y = iY;
((ChessWordBase)qz).Destroy();
}
}
}
#endregion
}
}
2. 象棋接口
using System;
using System.Collections;
namespace Zivsoft.Business.Chess
{
/// <summary>
/// 象棋接口
/// </summary>
interface IChess
{
/// <summary>
///
/// </summary>
int NextX { get; }
/// <summary>
///
/// </summary>
int NextY { get; }
/// <summary>
///
/// </summary>
/// <returns></returns>
ArrayList GetNextLocation();
/// <summary>
/// 如果是红色返回为真
/// </summary>
/// <returns></returns>
bool IsRedChess { get; }
/// <summary>
///
/// </summary>
bool IsDogFall { get; }
/// <summary>
/// 是否是进攻
/// </summary>
/// <returns></returns>
bool IsAttack { get; }
/// <summary>
///
/// </summary>
string Name { get; }
/// <summary>
///
/// </summary>
int X { get; }
/// <summary>
///
/// </summary>
int Y { get; }
/// <summary>
///
/// </summary>
/// <param name="X"></param>
/// <param name="Y"></param>
void Move(int x, int y);
/// <summary>
/// 移动
/// </summary>
/// <param name="X"></param>
/// <param name="Y"></param>
/// <param name="obj"></param>
void Move(int x, int y, object obj);
}
}
3. 接下来就是关键的部分，我曾在这里实现机器自动下棋，但是还是碰到一些困难
棋子移动
/// <summary>
/// 被吃时调用，或吃子时调用
/// </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void ChessWordUserControl_Click(object sender, EventArgs e)
{
if (Factory.IsTurnToRedChessWalking)
{
//机器下棋（Red)
if (this.IsRedChess)
{
//红方（机器）
}
else
{
//红方吃掉黑方
this.Eat(false);
return;
}
}
else
{
//用户下棋
if (this.IsRedChess)
{
//黑方吃掉红方
this.Eat(false);
return;
}
else
{
//黑方（用户）
}
}
if (Factory.OldQiZhi != null)
{
Factory.OldQiZhi._move = EChessDraw.Null;
Factory.OldQiZhi.Refresh();
}
Factory.WeiZhi_AL = this.GetNextLocation();
Factory.OldQiZhi = this;
this._move = EChessDraw.Click;
this.Refresh();
}
目前，我在网上查了不少资料，大家都想求一个比较厉害的象棋程序，可目前我的程序是最弱智的，CPU自己不会下。有人告诉我，说需要调用一些已经大师们的下棋残局API，而无需自己写一套规则，我觉得也是，不然写棋的那个人一定是下棋高手，可是我棋艺一般，但我很想写一个比较厉害的程序，让我的象棋以CPU的身份来挑战那些大师，呵呵，就是这样一个想法，目前用C#实现，先不讨论性能，能有人指点实现一下也不错。
如果有人有兴趣，我想把代码放在officelive.com上，其实重要不是代码了，感觉这些程序的算法和思想设计很重要，欢迎高手指点一二。:-)
