Take a look at the image below: It shows
one of the interactive demos of Irrlicht (btw, need to make a better looking one soon) which comes with the SDK. You can walk around and shoot fireballs. The demo also
has sound (fireballs) and music (by Markus Rohde).
The cool part of this: This is not the original C++ demo, but the demo rewritten in Java, using
jirr. Jirr has just been released in a new version by Stefan Dingfelder, supporting Irrlicht 1.2 as well as
irrKlang 0.5. That's very cool. And this means irrKlang already is available to be used in 4 languages: C++, C, FreeBasic and Java. (And before anyone asks, yep, I'm working on the irrKlang.NET port, adding languages such as C# and VisualBasic.NET).
