如何在gomoku中存储作品
当前正在学习MFC并决定制作游戏Gomoku。这是迄今为止的代码。如何在gomoku中存储作品

我的代码绘制一个15×15网格的函数DrawBoard（）和分别在OnLButtonDown中和OnRButtonDown绘制黑色和白色片。事情是当我运行程序并点击绘制黑色部分然后是白色部分时，白色部分可以绘制在黑色部分上，反之亦然。所以我想创建一个二维阵列板[15] [15]来存放一个作品时，它的绘制，以便一个不同的作品不能被绘制在当前的作品将是最好的（我在这里正确的轨道上）。我试过了，但我似乎无法弄清楚如何去做。我不擅长编程，并意识到这可能很容易，但一些帮助真的会被赞赏。请解释我将如何以正确的方式去做。
这就是我试过的。

return;
else {

dc.Ellipse(xCod, yCod, xCodx, yCody);
board[xCod][yCod] = BLACK;
}
}

回答：
您应该完成OnPaint中的所有图纸。不要画其他功能，例如OnLButtonDown。相反，从OnLButtonDown获取必要的信息并致电Invalidate，这将重新绘制窗口。
这里是一个例子。为了简单起见，我创建了一个结构info和一个二维数组data。 data存储每个单元格的所有信息，即矩形和颜色。你必须初始化data一次，并根据信息data
#include <vector> class CMainFrame : public CFrameWnd
{
...
struct info
{
CRect rect;
int color;
};
std::vector<std::vector<info>> data;
};
CMainFrame::CMainFrame()
{
...
data.resize(15);
for(int i = 0; i < data.size(); i++)
data[i].resize(15);
int xoffset = 20;
int yoffset = 20;
for(int row = 0; row < 15; row++)
{
for(int col = 0; col < 15; col++)
{
data[row][col].rect.SetRect(0, 0, size + 1, size + 1);
data[row][col].rect.MoveToXY(xoffset + row * size, yoffset + col * size);
}
}
}
void CMainFrame::OnLButtonDown(UINT nFlags, CPoint point)
{
CFrameWnd::OnLButtonDown(nFlags, point);
for(int row = 0; row < 15; row++)
{
for(int col = 0; col < 15; col++)
{
if(data[row][col].color)
break;
if(data[row][col].rect.PtInRect(point))
{
data[row][col].color = WHITE;
break;
}
}
}
Invalidate(FALSE);
}
void CMainFrame::OnRButtonDown(UINT nFlags, CPoint point)
{
CFrameWnd::OnRButtonDown(nFlags, point);
for(int row = 0; row < 15; row++)
{
for(int col = 0; col < 15; col++)
{
if(data[row][col].color)
break;
if(data[row][col].rect.PtInRect(point))
{
data[row][col].color = BLACK;
break;
}
}
}
Invalidate(FALSE);
}
void CMainFrame::OnPaint()
{
CPaintDC dc(this);
CPen pen(PS_SOLID, 1, RGB(0, 0, 0));
dc.SelectObject(&pen);
CBrush white, black;
white.CreateSolidBrush(RGB(255, 255, 255));
black.CreateSolidBrush(RGB(0, 0, 0));
for(int row = 0; row < 15; row++)
{
for(int col = 0; col < 15; col++)
{
dc.Rectangle(data[row][col].rect);
if(data[row][col].color)
{
CBrush *oldbrush;
if(data[row][col].color == WHITE)
oldbrush = dc.SelectObject(&white);
else
oldbrush = dc.SelectObject(&black);
dc.Ellipse(data[row][col].rect);
dc.SelectObject(oldbrush);
}
}
}
}
