Dynamic Subclasses?

I'm working on a game that uses tiles. It's setup so players can make their own maps with the default tiles given. I want to make it so users can can create their own tiles with their own properties in a text file and be loaded to the game with all of its properties as a tile subclass. Is it possible to create subclasses like this?

More than it could be an object isn't it? What you really mean by dynamic classes?

Ok, here is an example of some tiles programmed normally-

Code:

---

public class Tile
{
        Color c;
        Image texture;
        int alpha;
        int bounce;
        boolean solid;
        boolean buildable;
        boolean smoothDraw;
       
        etc...       
               
        public Tile()
        {
                c = new Color(Color.BLACK);
                texture = null
                bounce = 0;
               
                etc...
        }
}

public class Grass extends Tile
{
        public Grass()
        {
                c = new Color(Color.GREEN);
               
                etc...
        }
}

public class Dirt extends Tile
{
        etc...

---

But what is a user wants to make a tile called "Trampoline" for his/her map that has a bounce property of 20. So that when a user comes down on it they will bounce. Can I dynamically generate this subclass based on that property?

I know it's possible to make a Tile object and just set all these values one by one in a loop. But a map may have tens of thousands of tiles. Is that the only way it can be done or can I dynamically make the "Trampoline" subclass someway and add it to the Tile grid?

One solution is to rather than making a bunch of classes, make one Tile class that is flexible enough to change properties. And why not change the values in a loop? Even if you have many tiles this can work.

That's what I originally thought but I also thought that was a little primitive. So I guess I will go with that.

Yes, in a one class make possible to change required parameters according to your design. Then you may need to deals with additional values in a situation, if any. Otherwise only thing you've to do is assign appropriate values.
