我的源代码是......

abstract class GameObject
{
    public abstract void Move();
    public abstract void Draw(Graphics g);
}

class Pacman : GameObject
{
    public override void Move()
    {
        //Update the Position of Pacman, check for collisions, ...
    }

    public override void Draw(Graphics g)
    {
        //Draw Pacman at his x and y coordinates
    }
}

class Monster : GameObject
{
    public override void Move()
    {
        //Update the Position of the Monster, ...   
    }

    public override void Draw(Graphics g)
    {
        //Draw the Monster at his current position
    }
}

    private Pacman _pacman;
    private Monster _monster;
    private List<GameObject> _gameobjects = new List<GameObject>();

    public GameClass()
    {

        _monster = new Monster();
        _gameobjects.Add(_pacman);
        _gameobjects.Add(_monster);
    }


    private void TimerTick()

        }
        //Draw every single GameObject to the Bitmap
        Bitmap bitmap = new Bitmap(panBox.Width, panBox.Height);
        using (Graphics g = Graphics.FromImage(bitmap))
        {
            foreach (var gameobject in _gameobjects)
            {

        //Draw the Bitmap to the screen
        using (Graphics g = panBox.CreateGraphics())
        {
