The Gold Key sprite

This is an example of a gettable sprite. All it really has is its initialisation, most of which it inherits from the Sprite class, and the save and restore code.

I can't help feeling that a lot of the save and restore stuff could be in the parent class too for movable / gettable sprites.

import java.util.Vector;
import java.awt.Point;
public class GoldKey extends Sprite
{
    public GoldKey(String spriteName, String Scenename)
    {
        super(spriteName, Scenename, "goldk.gif", MULTIPLE, 
            2, GETTABLE, NOACTION);
        setPosition(100, 400);
        setSize(40, 20);
        addValidDrop("inventory", -1, -1);
        addValidDrop("dock", 100, 400);
    }
    public String saveMe()
    {
        String mysave = getSavePrefix();
        mysave = mysave.concat("[" + scenename + "]");
        mysave = mysave.concat(posSave());
        mysave = mysave.concat(gotSave());
        mysave = mysave.concat(">");
        return mysave;
    }
    public boolean restoreMe(String restoreString)
    {
        String search = getRestoreContent(restoreString);
        int start = search.indexOf("[");
        if (start != -1)
        {
            start +=1;
            int end = search.indexOf("]", start);
            if (end != -1)
            {
                scenename = search.substring(start, end);
                start = search.indexOf("[X", end);
                end = search.indexOf("]", start);
                Point p = posRestore(search.substring(start, end+1));
                setPosition(p.x, p.y);
                if (search.indexOf("[NOTGOT]") != -1)
                {
                    if (dropSprite(scenename))
                    {
                        return true;
                    }
                }
                else if (search.indexOf("[GOT]") != -1)
                {
                    getSprite();
                }
            }
        }
    return false;
    }
}
