在C#中循环时重新启动

我是C#的初学者，创建了一个小游戏，用户可以在其中以一定的重力、速度和随机风投球。球应该击中一个目标，（当它击中时）给用户分数，然后回到起始位置，让用户再次投球。除了把球带回首发位置之外，我已经把一切都做好了。如有任何帮助，我们将不胜感激！

以下是我的代码的一些部分：

   private void goButton_Click(object sender, EventArgs e) 
    {
        if (running == true) 
        {
            b1.Location = new Point(0, 300); 
            b1.speedX = (double)upDownX.Value; 
            b1.speedY = (double)upDownY.Value; 
            running = false; 
            b1.Start();
            return;
        }
        running = true;
        worker = new BackgroundWorker();
        worker.DoWork += new DoWorkEventHandler(RunMe);             worker.RunWorkerAsync(); 
    }
public void RunMe(object sender, DoWorkEventArgs e)
    {
        while (running)
        {
            if (b1.speedY > 0 && b1.Location.Y > panel.Size.Height - b1.Size.Height)
            {
                b1.posY = panel.Size.Height - b1.Size.Height;
                addPoints();
                running = false;
                BeginInvoke((MethodInvoker)delegate
                {
                    b1.Location = new Point(0, 300);
                });
            }
            if (b1.speedX > 0 && b1.Location.X > panel.Size.Width - b1.Size.Width)
            {
                running = false;
                if (b1.Location.Y < 290 && b1.Location.Y > 150 && b1.Location.X > 430)
                {

                    {

                    }
                    if (diffValue.Text == "Easy")
                    {
                        Ball.score += 7;
                    }
                }
                else if (b1.Location.Y < 390 && b1.Location.Y > 60 && b1.Location.X > 430)

                addPoints();

                goto restart;
            }

            {
                b1.BounceX();
            }

            this.Invoke(new MoveBallCallback(MoveBall), b1);
            Thread.Sleep(10);
