六子棋界面开发实例

清疚 2022-06-11 05:52 101阅读 0赞

开发工具：Qt 5.7.0

项目名称：六子棋界面

首次开发并没有使用UI，纯代码实现

实现效果：

1.选择先手后手，鼠标拖动单击落子

2.悔棋（支持一轮悔棋，可修改支持多轮）

3.暂停

4.终止、清除棋盘

5.定时

6.人机对战（ai比较笨）

棋盘采用划线函数实现:

void MainWindow::paintEvent(QPaintEvent *event)
    {
        QPainter painter(this);
        painter.drawPixmap(0,0,width(),height(),QPixmap("blcjaiffa.png"));
        painter.setRenderHint(QPainter::Antialiasing,true);  //抗锯齿
        for(int i=0;i<GRID_NUM;i++)
        {
            painter.drawLine(30+40 * i, 750,30 +40 * i,30);
            painter.drawLine(30,30+40 * i,750,30+40 * i);
    //        painter.drawLine(kBoardMargin, kBoardMargin + kBlockSize * i, size().width() - kBoardMargin, kBoardMargin + kBlockSize * i);
        }
        QBrush brush;
        brush.setStyle(Qt::SolidPattern);
        brush.setColor(Qt::black);
        painter.setBrush(brush);
        painter.drawEllipse(34 +40* 9 - 10, 34 + 40 *9 - 10, 5 * 2, 5 * 2);
        for (int i = 0; i < 19; i++)
            for (int j = 0; j < 19; j++)
            {
                if (cb[i][j] == 1)
                {
                    brush.setColor(Qt::white);
                    painter.setBrush(brush);
                    painter.drawEllipse(30 +40* j - 10, 30 + 40 * i - 10, 10 * 2, 10 * 2);
                }
                else if (cb[i][j] == 7)
                {
                    brush.setColor(Qt::black);
                    painter.setBrush(brush);
                    painter.drawEllipse(30 +40* j - 10, 30 + 40 * i - 10, 10 * 2, 10 * 2);
                }
    
            }
    }

鼠标move函数和鼠标release函数：

void MainWindow::mouseMoveEvent(QMouseEvent *event)
    {
      //  this->setMouseTracking(TRUE);   //设置窗体追踪鼠标
        int x=event->x();   //获取鼠标位置
        int y=event->y();
        int len=0;
        //非棋盘区域不能落子
        if(x>30 && x<750 && y>30 && y<750)  //确定棋盘位置
          {
           int col = x / 40;
           int row = y / 40;
           int leftTopPosX = 30 + 40 * col;
           int leftTopPosY = 30 + 40 * row;
           // 根据距离算出合适的点击位置,一共四个点，根据半径距离选最近的
           clickPosRow = -1; // 初始化最终的值
           clickPosCol = -1;
           //int len = 0; // 计算完后取整就可以了
    
           // 确定一个误差在范围内的点，且只可能确定一个出来
           len = sqrt((x - leftTopPosX) * (x - leftTopPosX) + (y - leftTopPosY) * (y - leftTopPosY));
           if (len < 10)
           {
               clickPosRow = row;
               clickPosCol = col;
           }
                 len = sqrt((x - leftTopPosX - 40) * (x - leftTopPosX - 40) + (y - leftTopPosY) * (y - leftTopPosY));
                 if (len < 10)
                 {
                     clickPosRow = row;
                     clickPosCol = col + 1;
                 }
                 len = sqrt((x - leftTopPosX) * (x - leftTopPosX) + (y - leftTopPosY - 40) * (y - leftTopPosY - 40));
                 if (len < 10)
                 {
                     clickPosRow = row + 1;
                     clickPosCol = col;
                 }
                 len = sqrt((x - leftTopPosX - 40) * (x - leftTopPosX - 40) + (y - leftTopPosY - 40) * (y - leftTopPosY - 40));
                 if (len < 10)
                 {
