关于C#多线程程序设计

想写个双人坦克小游戏，想要双人玩需要用到多线程，以下是我写的代码，没能实现效果，想请教以下大家哪里错了，先谢谢了。

程序代码：

        Thread thread1, thread2;
        Message m;
        Keys k;
        int x1 = 0, y1 = 0, x2, y2;
        Bitmap pic1 = new Bitmap("C:\\Users\\llq664301573\\Desktop\\res\\己方1上.gif");
        Bitmap pic2 = new Bitmap("C:\\Users\\llq664301573\\Desktop\\res\\己方1下.gif");
        Bitmap pic3 = new Bitmap("C:\\Users\\llq664301573\\Desktop\\res\\己方1左.gif");
        Bitmap pic4 = new Bitmap("C:\\Users\\llq664301573\\Desktop\\res\\己方1右.gif");
        public void func1()
        {
            switch (k)
            {
                case Keys.Up:
                    y1 -= 8;
                    pictureBox1.Top = y1;
                    pictureBox1.Image = pic1;
                    pictureBox1.Width = pic1.Width;
                    pictureBox1.Height = pic1.Height;
                    break;
                case Keys.Down:
                    y1 += 8;
                    pictureBox1.Top = y1;
                    pictureBox1.Image = pic2;
                    pictureBox1.Width = pic2.Width;
                    pictureBox1.Height = pic2.Height;
                    break;
                case Keys.Left:
                    x1 -= 8;
                    pictureBox1.Left = x1;
                    pictureBox1.Image = pic3;
                    pictureBox1.Width = pic3.Width;
                    pictureBox1.Height = pic3.Height;
                    break;
                case Keys.Right:
                    x1 += 8;
                    pictureBox1.Left = x1;
                    pictureBox1.Image = pic4;
                    pictureBox1.Width = pic4.Width;
