        }

        {
            x = ix;
            y = ix;
        }

    The error is telling you exactly what's wrong. You are calling getDocumentBase() in player without calling it on any object or class, as if the Player class has this method itself, and the error is telling, that the Player class does not in fact have this method. I don't do applet programming, but I seem to remember that this method is a method of Applet. Regardless, check the API as it will tell you if this is so or not.
