Write a simple program backgammon game with C ++ MFC

Brief

After learning C ++ MFC program, on the initiation of the idea to write a 331 procedures. Indeed, with C # to write the words of the interface may be much better, but my main goal but not the interface algorithm, so the use of the MFC VS to write programs.

Program realization

step1: Create a MFC dialog in VS program (This step may reference specific program, this paper is given a simple implementation)
Step2: a new class called CMainGobang, the preparation of the main class code
(the complete code visit my GitHub: https://github.com/Vaczzy/SimpleGobang )

• Add the required header files used in the function declaration in the class and structure

struct Pieces//棋子判断单元
{
	bool bIsPieces;//是否已有棋
	bool bIsBlack;//黑棋或白棋
	int x,y;//棋子所在格
};

struct MyRectangle
{
	int x,y;//选中框核心坐标
};

public:
	CMainGobang(void);
	~CMainGobang(void);
private:
	/////basic information
	int iSize;//棋盘大小参数
	int xmax,xmin,ymax,ymin;//棋盘大小参数
	int idx;//棋盘每小格长度
	/////pieces information
	int iPieces;//棋子计数//当前棋子计数为iPieces-1
	int iPiecesNum;//棋子总数
	Pieces *pPieces;//棋子
	/////rectangle information
	int iRectangleNum;//选中框个数
	MyRectangle *pmyRectangle;//选中框
	/////for draw rectangle&draw pieces
	bool NoRectangle(int x,int y);//判断该位置上是否有选中框
	bool NoPieces(int x,int y);//判断该位置上是否有棋子
	/////for judge win
	bool IsBlack(int x,int y);//判断该位置上棋子颜色
	bool IsConnect(int iDir,int x,int y);//查找相连的棋子
	int ConnectNum();//返回相连棋子个数
	/////for machine fight
	//void MaConnectNum(int iConnectNum,int iDir);//返回弱相连棋子个数/iDir方向参数
	int ConnectDir();//返回相连棋子方向
public:
	void DrawMainTable(CDC *pDC,CRect rect,int iTableSize);//绘制棋盘函数
	void SetPieces();//设参函数//将初始化代码与绘制棋盘代码分开
	void DrawRectangle(CDC *pDC,CPoint pt);//绘制选中框/返回是否绘制
	void DrawPieces(CDC *pDC,CRect rect,CPoint pt);//绘制棋子函数
	bool ClearPieces(CDC *pDC,bool &bBlack);//清除棋子函数/用于悔棋
	void KeepPieces(CDC *pDC,CRect rect,int iTableSize);//循环绘制棋子 //用以解决刷新问题
	void MachineDraw(CDC *pDC);//机器下棋函数

	bool Success();//判断胜利函数
	void ReplayMark(CDC *pDC);//复盘标记函数

• Add function to achieve the class cpp file
  (just to name a function to draw the board)

CMainGobang::CMainGobang(void)
{
}

CMainGobang::~CMainGobang(void)
{
	if(pPieces!=NULL)
	{
		delete []pPieces;
		pPieces=NULL;
	}
	if(pmyRectangle!=NULL)
	{
		delete []pmyRectangle;
		pmyRectangle=NULL;
	}
}

//绘制棋盘函数
//后期可添加棋盘大小参数
//控件坐标
void CMainGobang::DrawMainTable(CDC *pDC,CRect rect,int iTableSize)
{
	iSize=iTableSize;
	//先覆盖背景
	CRect Back;
	Back.top=rect.top+1;
	Back.bottom=rect.bottom-1;
	Back.left=rect.left+1;
	Back.right=rect.right-1;
	pDC->FillSolidRect(&Back,RGB(240,240,240));//填充
	//计算每格长度
	idx=(((rect.right-rect.left)/(iTableSize+1))>((rect.bottom-rect.top)/(iTableSize+1)))?
		(rect.bottom-rect.top)/(iTableSize+1):
	    (rect.right-rect.left)/(iTableSize+1);
	CBrush brush(RGB(0,0,0));
	CBrush *OldBrush=pDC->SelectObject(&brush);
	int ixp,iyp;//棋盘星坐标
	//绘制天元
	ixp=(rect.right-rect.left)/2;
	iyp=(rect.bottom-rect.top)/2;
	pDC->Ellipse(ixp-3,iyp-3,ixp+3,iyp+3);
	//绘制星
	ixp-=4*idx;
	iyp-=4*idx;//左上角
	pDC->Ellipse(ixp-3,iyp-3,ixp+3,iyp+3);
	iyp+=8*idx;//左下角
	pDC->Ellipse(ixp-3,iyp-3,ixp+3,iyp+3);
	ixp+=8*idx;//右下角
	pDC->Ellipse(ixp-3,iyp-3,ixp+3,iyp+3);
	iyp-=8*idx;//右上角
	pDC->Ellipse(ixp-3,iyp-3,ixp+3,iyp+3);
	pDC->SelectObject(OldBrush);//恢复设备环境中原来的画笔
	brush.DeleteObject();//释放绘图资源
	//计算棋盘大小并放置于窗口中间
	ymin=(rect.bottom-rect.top)/2-(iTableSize-1)/2*idx;
	ymax=ymin+(iTableSize-1)*idx;
	xmin=(rect.right-rect.left)/2-(iTableSize-1)/2*idx;
	xmax=xmin+(iTableSize-1)*idx;
	for(int x=xmin;x<=xmax;x+=idx)
	{
		pDC->MoveTo(x,ymin);
		pDC->LineTo(x,ymax);
	}
	for(int y=ymin;y<=ymax;y+=idx)
	{
		pDC->MoveTo(xmin,y);
		pDC->LineTo(xmax,y);
	}
}

step3: write-related interface code in xxxx (xxxx project name created for you) Dlg.cpp in
this step is mainly to write some code related to the interface
, such as moving the mouse to draw a process in its corresponding position of chess a rectangular frame (FIG see below)

//鼠标移动函数
void CMyGobang_DHKDlg::OnMouseMove(UINT nFlags, CPoint point)
{
	// TODO: 在此添加消息处理程序代码和/或调用默认值
	CPoint pt;
	CRect rect;
	GetDlgItem(IDC_MainTable)->GetWindowRect(&rect);//获取控件屏幕坐标
	GetCursorPos(&pt);//获取鼠标点击坐标(屏幕坐标坐标)
	pt.x-=rect.left;//转化为控件中坐标
	pt.y-=rect.top;
	CDC *pDC=picMain.GetDC();//获取该控件的画布
	if(bIsReady)
	{
		gobang.DrawRectangle(pDC,pt);
	}
	
	CDialogEx::OnMouseMove(nFlags, point);
}

Finally, if you have any improvements to the algorithm of this program can go to my github address: https://github.com/Vaczzy/SimpleGobang . In this address, you can also see a more detailed description of this program, I have labeled my email address, if you have any questions, you can contact me via this address :)
