Dynamic Subclasses?

[MrFish]

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?

[MrFish]

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

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.

[MrFish]

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.
