This article mainly introduces how to develop chess programs based on C++ and MFC. It is very detailed and has a certain reference value. Interested friends must finish reading it.

First, chessboard analysis

This is the chessboard I drew. The chessboard consists of 9 vertical lines and 10 horizontal lines. Here we set the interval between each line to be 50.

Second, the drawing process

1. Create a new MFC program in vs to remove the buttons and text automatically generated by the environment.

2. Open the * Dlg.cpp file, define a chessboard interval value in void CChessDlg::OnPaint () and the drawing device CDC * cd = CWnd::GetDC ()

Int nWid = 50 China CDC * cd = CWnd::GetDC ()

3. Draw the horizontal line of the chessboard

/ / draw a dash for (int I = 1; I

MoveTo (nWid, I * nWid); cd- > LineTo (9 * nWid, I * nWid);}

4. Draw the vertical line of the chessboard

/ / draw a vertical bar for (int I = 1; I

MoveTo (I * nWid, nWid); cd- > LineTo (I * nWid,10 * nWid);} else// draws vertical lines in the middle of the chessboard {cd- > MoveTo (I * nWid, nWid); cd- > LineTo (I * nWid,5 * nWid); cd- > MoveTo (I * nWid,6 * nWid); cd- > LineTo (I * nWid,10 * nWid);}}

5. Draw Nine Palace grids

/ / painting Nine Miyagi CD-> MoveTo (4 * nWid, nWid); cd- > LineTo (6 * nWid,3 * nWid); cd- > MoveTo (6 * nWid, nWid); cd- > LineTo (4 * nWid,3 * nWid); cd- > MoveTo (4 * nWid, 8 * nWid); cd- > LineTo (6 * nWid,10 * nWid); cd- > MoveTo (6 * nWid, 8 * nWid); cd- > LineTo (4 * nWid,10 * nWid)

At this point, our chessboard is drawn. Here is the complete code.

CDialogEx::OnPaint (); int nWid = 50; CDC * cd = CWnd::GetDC (); / / dash for (int I = 1; I

MoveTo (nWid, I * nWid); cd- > LineTo (9 * nWid, I * nWid);} / / draw vertical bar for (int I = 1; I

MoveTo (I * nWid, nWid); cd- > LineTo (I * nWid,10 * nWid);} else {cd- > MoveTo (I * nWid, nWid); cd- > LineTo (I * nWid,5 * nWid); cd- > MoveTo (I * nWid,6 * nWid); cd- > LineTo (I * nWid,10 * nWid);}} / / draw Jiugong cd- > MoveTo (4 * nWid, nWid); cd- > LineTo (6 * nWid,3 * nWid) Cd- > MoveTo (6 * nWid, nWid); cd- > LineTo (4 * nWid,3 * nWid); cd- > MoveTo (4 * nWid, 8 * nWid); cd- > LineTo (6 * nWid,10 * nWid); cd- > MoveTo (6 * nWid, 8 * nWid); cd- > LineTo (4 * nWid,10 * nWid); these are all the contents of the article "how to develop Chess programs based on C++ and MFC".
