Keeping old values of variable in constructor in qt and cpp

Question

I am using Qt and Cpp (on windows 10). I have a situation in my application. The application is a Falling Ball game. Basically, the game is that balls keeps on falling at regular intervals of 3 secs. There is a rectangle that acts as a basket to catch the ball. I have defined the dimensions of the ball and basket in the Sprite class as shown below. My question is, as I have sprites being created at regular intervals, the dimensions of the BAR(rectangular basket x1 and y1) are defined in the Sprite constructor. Whenever I create a new sprite every 3 secs, the default values of x1 and y1 are set ignoring the current values obtained by the position of the basket. How can I keep the old values of x1 and y1, while creating new sprites at regular intervals?

Sprite.h

int x=0;//position of sprite in x-direction.

    int y=0;//position of sprite in y-direction.

    int dx=1;//difference in x-direction position.

    int dy=1;//difference in y-direction position.

     int x1=0;//position of the basket in x-direction

     int y1=0   ;//position of the basket in y-direction.

Sprite.cpp

Sprite::Sprite(QWidget *p)
{
    parent=p;
    QRect rct = parent->rect();
    x = rand() % rct.width();//randomly initialize the x-position for the sprite.
    y=rct.height()*0.05;//start position for the sprite is about 5% after the top of the menu bar.

    dx = rand() % 10;//the speed is randomly set in x-direction.    
    dy = 4;

    x1=rct.width()/2;
    y1 = rct.height() - 80;
    start(10);
}


void Sprite::drawBall(QPainter &painter)
{
    painter.drawEllipse(x, y, 15, 15);
}

void Sprite::drawBar(QPainter &painter)
{
    painter.drawRect( x1, y1, 80, 30);
}

void Sprite::move(int nDirection)
{
    QRect rct = parent->rect();
    if(nDirection == 0)
    {
        if(x1 >= 0 )             x1 += -15;
    }
    else
    {
        if(x1+80 < rct.width()){x1 += 15;}
    }
}

void Sprite::timerEvent(QTimerEvent *event)
{
     QRect rct = parent->rect();
    if ( x > rct.width() || x < 0)
        dx *= -1;
    if ( y > rct.height() || y < 0)
        dy *= 1;
     if (event->timerId() == timerId1)
     {
        qDebug() << "Timer ID:" << event->timerId();
     }

    x += dx;
    y += dy;

         if( (((y - 15) >= 520)&& y <550 ) && ( (x <= (x1 + 80)) && (x >= (x1 - 80)) ))
        {
            qDebug("x and y position when condition is met and also x1 and y1");
            qDebug()<<x;
            qDebug()<<y;
            qDebug()<<x1;
            qDebug()<<y1;
            dy *= -1;
            dx *= -1;
        }    
    parent->update();
}

MainWindow.cpp

MainWindow::MainWindow(QWidget *parent)
    : QMainWindow(parent)
    , ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    qDebug() <<"mainWindow constructor";    
     QTimer *timer;    
     timer=new QTimer(this);
      connect(timer, &QTimer::timeout, this, &MainWindow::onTimer);
     timer->start(3000);    
}

void MainWindow::onTimer()
{
    sprite = new Sprite(this);
    connect(this, &MainWindow::draw, sprite, &Sprite::drawBall);
}
