使用QT5.2.0和Qt Creator3.0.0，实现了2048小游戏。自定义了方块类和视图类，但游戏尚存在不足，如缺少合并特效、移动轨迹，新方块出现方式不理想，合并算法复杂，程序逻辑需优化。附带游戏效果图。

QT环境：QT5.2.0,Qt Creator3.0.0

1.自定义方块类

class Square : public QGraphicsItem
{
public:
    explicit Square(QPoint pos,QString text,QString background_color);
    QString getText() {return text;}
    void    updatePos(QPoint pos);
    void    updateText(QString text,QString background_color);
    void    updateBox(QPoint pos,QString text,QString background_color);
    enum {Type = UserType + 1};
    int     type() const;
private :
    QRectF  boundingRect() const;
    void    paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget);
    QString text;
    QString color;
};

Square::Square(QPoint pos,QString text,QString background_color) : QGraphicsItem()
{
    setPos(pos);
    this->text = text;
    this->color = background_color;
    setFlag(QGraphicsItem::ItemIsFocusable);
}
int Square::type() const
{
    return Type;
}
QRectF Square::boundingRect() const
{
    int penWidth = 1;
    return QRectF(0-penWidth/2,0-penWidth/2,105+penWidth,105+penWidth);
}
void Square::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{
    Q_UNUSED(option);
    Q_UNUSED(widget);
    //画背景
    painter->setPen(QColor(color));
    painter->setBrush(QBrush(QColor(color)));
    painter->drawRect(QRect(0,0,105,105));
    //设置字体 字号
    switch(text.length())
    {
    case 1:
        painter->setFont(QFont(QString::fromLocal8Bit("微软雅黑"),50,QFont::Bold));
        break;
    case 2:
        painter->setFont(QFont(QString::fromLocal8Bit("微软雅黑"),40,QFont::Bold));
        break;
    case 3:
        painter->setFont(QFont(QString::fromLocal8Bit("微软雅黑"),35,QFont::Bold));
        break;
    case 4:
        painter->setFont(QFont(QString::fromLocal8Bit("微软雅黑"),30,QFont::Bold));
        break;
    default:
        break;
    }
    //设置字体颜色
    if(text.toInt() == 2 || text.toInt() == 4)
    {
        painter->setPen(QColor("#7c736a"));
    }
    else if(text.toInt() >= 8)
    {
        painter->setPen(QColor("#fff7eb"));
    }
    painter->drawText(QRect(0,0,105,105),Qt::AlignCenter,text);
}
void Square::updatePos(QPoint pos)
{
    setPos(pos);
    update(boundingRect());
}
void Square::updateText(QString text,QString background_color)
{
    this->text = text;
    this->color = background_color;
    update(boundingRect());
}
void Square::updateBox(QPoint pos,QString text,QString background_color)
{
    this->text = text;
    this->color = background_color;
    setPos(pos);
    update(boundingRect());
}

2.自定义视图类

class GameView : public QGraphicsView
{
    Q_OBJECT
public:
    explicit GameView();
    ~GameView();
private:
    QGraphicsScene *g_scene;
    QMap<qreal,QString> colorBox;
    void    createGrid();
    void    createColorBox();
    void    startGame();
    void    restartGame();
    bool    upMerge();
    bool    downMerge();
    bool    leftMerge();
    bool    rightMerge();
    bool    newSquare();
    void    countEmpty(QList<QPair<int,int> > &empty_index);
    bool    checkSucceeded();
    bool    checkFinished();
    void    keyPressEvent(QKeyEvent * event);
    void    drawBackground(QPainter * painter, const QRectF & rect);
public slots:
};
GameView::GameView() : QGraphicsView()
{
    g_scene = new QGraphicsScene();
    g_scene->setSceneRect(0,0,500,500);
    setScene(g_scene);
    setCacheMode(QGraphicsView::CacheBackground);
    setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
    createGrid();
    createColorBox();
    startGame();
}
