hi!,

i think its a annoying failure and often discussed problem. :oops:
But there is the Exception:

Code:
Exception in thread "main" java.lang.IllegalArgumentException: url is null
   at de.matthiasmann.twl.theme.ThemeManager.createThemeManager(ThemeManager.java:148)
   at world0.GameplayState.init(GameplayState.java:174)
   at org.newdawn.slick.state.StateBasedGame.init(StateBasedGame.java:171)
   at org.newdawn.slick.AppGameContainer.setup(AppGameContainer.java:390)
   at org.newdawn.slick.AppGameContainer.start(AppGameContainer.java:314)
   at world0.World0Game.main(World0Game.java:35)


The .xml is from tut and its on the right place (I think so :P):

And as always it's the same answer - you pass a null URL into createThemeManager() - so it is clearly a user error.
And that means the file is not where your application tries to find it.

You try to load it via the class path, and relative to your GameplayState class - it helps to read the javadoc of Class.getResource.
