"In my awesome experience, Irrlicht GUI is shit. Sorry. "
The main reason I liked Irrlicht is it was the easiest to understand and use open graphics engine that I knew of. I'd tried Panda3D and though the community was great when I used it, I prefered Irrlicht for it's tutorials, documentation (not just community). It has been over a year and a half since I did a unit with open source engines tho so things may have changed in that time.
"libRocket has taken my interest lately -- "
I'll google it and check it out.
"Good luck on your project -- if you're still working on it."
Cheers. Still in drips and drabs since I've been major busy these past months. While I was hopeful to have a lot of free time after I finished my honours in February, but job search and a gazzillion other projects have me moving back and forth between Arcanum and other stuff.
At the moment tho I'm going over 3D maths and code stuff from one of my old units for a potential simulation job so that will go some ways to get me back on track. It was always my plan to see it through to the end, but most likely I'll really get into it after I finish writing my random battles tutorial either tonight or tomorrow.
Might be a bit diluted by the fact I've been making my own Arcanum module recently but hey, what AREN'T I working on
