How do You debug variables on Screen?

Debuging variables is a common task in game-dev. You allways come to a point where You want to know the x/y/z position of Your disposal hero at realtime. Of cause its possible to log down all values on console/logFile [via printf()] easily, but that will be hard to track by Your eyes. So You may want to display some dbg-info into the game screen. The info should be always on top of the scene, therefore You may use the inbuild GuiEnvironment module. BUT which gui-widget is best to do this? [addStaticText() ?] Maybe You have other solutions? Especialy to track changing values in realtime...

If it's something small, such as the FPS, or position of something, you could always place it in the title bar. Otherwise, use IGUIStaticText.

It sounds like you want a debug console. A console lets you execute commands in your game while it is running and dump the output to an overlay window.

I implemented my own before I found IrrConsole by Mohaps.

I just use my bitmap font routine to ouput vars on screen when I press the "debug key" I have set up - and can dump it to a text file log with another press. It uses the same font as my game uses at the time and it's fast!
