nothing fancy, just pretty useful. nothing none of you couldn't have written yourselves, but perhaps you didn't think of this :)
this just opens a simple Frame and displays some info. it can be used instead of a debugger to display information and is far better than System.out.println().
i couldn't be bothered to fiddle with the debugger in Eclipse so i wrote this instead since i needed to display lots of information at the same time.

this is how it's used:
1. in the constructor of some object, like a sprite for instance, create an instance:
1
| DebugWindow debugWindow = new DebugWindow(200, 200); |
2. somewhere in your code add the following (just an example):
1

5
| debugWindow.addValue("lateralForceFront", lateralForceFront);
debugWindow.addValue("pos x", x);
debugWindow.addValue("pos y", y);
debugWindow.addValue("speed", speed);
debugWindow.display(); |
a good place to add this is something that's called every loop, say move() or performGameTick() or whatever you call it. you get the idea.
