Note - before you run the jar file, you need to edit one line in mapman.cfg:
Code: 
imgfolder=e:\rpg\images\

to point correctly to the image folder.
For example, if you extracted the dist folder to the root of C:, you would change it to:
Code: 
imgfolder=c:\dist\images\


I know, I know, the 32x32 pngs look like ***. I'm more concerned about code atm.

My only concerns at the moment are how to add different objects, such as rocks, npcs, and the like. I'm going to have them all be a subclass of a class Drawable, but I'm not sure how to give different qualities without a compiled java file for each type of drawable =/.

You should probably use an interface for that.

Uh, what?

Also you don't need to use absolute paths in the config file. Just use "images/" as the path.

The map doesn't redraw when you drag the scrollbars.

Thanks for noticing that, before I released I had it redraw the whole map and so I sloppily threw together some code that only redrew what was visible in the window. I'll throw together a Listener for the scroll bars.

Also, I'm going to look into the interface idea, I'm not super acquainted with them but I know why they should be better.

Also, unless you're doing something significantly different from existing software, there's no reason to write yet another tile editor. So what are you doing different?

That whole "it's been done a million times" gets old to me, Reid, good work keep it up

I imagine it's for learning.

Also, you should implement your GUI properly with layout managers. That way, the window contents can properly resize when you resize the window.

Generally, you should use an interface when you want to define additional functionality that can be tacked on to any class. You should use an abstract class if you intentionally want to force your classes to inherit from it to get the functionality.

For example, there are probably many types of objects that can be drawn on the screen, so you should make Drawable an interface. A monster can be drawable, a tile can be drawable, an explosion can be drawable, etc. If you used an abstract class, all those objects would share a common ancestor, which doesn't make sense. Tile shouldn't be related to monster in that fashion.

Something like monster or creature would probably be an abstract class. Anything inheriting from it is, by necessity, a monster/creature. You don't want an interface because you don't want a tile that's also a monster -- that makes no sense.

I see. Class Monster would implement drawable and all monsters would extent Class Monster.

Also, heres the code for a binary tree I plan to use:
Code: 
/* * * * * * * * * * * * * * * * * * * * * *
 * BinTree.java
 * © 2009 Reid Booth
 * * * * * * * * * * * * * * * * * * * * * */
public class BinTree<V>{
	private String identifier;
	private V value;
	private BinTree<V> smaller;
	private BinTree<V> bigger;
	public BinTree(){
	}
	public BinTree(String id, V v){
		identifier = id;
		value = v;
	}
	public void setValue(String id, V v){
		if(identifier==null||identifier.equals(id)){
			identifier = id;
			value = v;
		}
		else if(id.compareTo(identifier)<0){
			if(lower==null){
				lower = new BinTree<V>(id,v);
			}
			else{
				lower.setValue(id,v);
			}
		}
		else{
			if(bigger==null){
				bigger = new BinTree<V>(id,v);
			}
			else{
				bigger.setValue(id,v);
			}
		}
	}
	public V getValue(String id){
		if(identifier!=null&&identifier.equals(id)){
			return value;
		}
		else if(id.compareTo(identifier)<0&&lower!=null){
			return lower.getValue(id);
		}
		else if(id.compareTo(identifier)>0&&bigger!=null){
			return bigger.getValue(id);
		}
		else{
			return null;
		}
	}	
}


I plan to add a remove method, but I'm not at a PC with a compiler so I can't test any code.
