magicman	glut32.dll not found. might just be a problem with me, but mabey not.
Tuesday, 26 September 2006, 10:09
HoboBen	Okays... Next version won't even use glut32.dll I'll keep ya posted.
Tuesday, 26 September 2006, 11:38
hyruleknight	they file you posted won't run to begin with OS: win2000
Tuesday, 26 September 2006, 15:04
Jayenkai	I think he's working in Linux, there, btw.. ... I didn't add an OS thing, did I..
Wednesday, 27 September 2006, 14:54
HoboBen	I've got it working on both (well, I used wine for it in Linux, but Windows 98 and XP ran it ok), but as I said, this version is sucky and the next version will use decent libraries that should exist as stanrard.
Wednesday, 27 September 2006, 17:56
hyruleknight	ok, i can't wait till my ubuntu CDs come in so i can try it out on linux i am going to make sure i have OpenGL and wine installed, BMAX freakin rocks!!! after i learn C/C++ i will be able to use it's inline functions and add some things like mic input and probably learn to make dll wrappers(oh the headaches) still can't wait to play this thing and don't worry with time your skills will get better and you already have a good understanding of 3D math so it is only a matter of time before your games made in C++ get better i will start 3D after Max3D comes out or i will use the MiniB3D modules
Thursday, 28 September 2006, 15:28
HoboBen	Yay for Ubuntu! Anyway, the next version of this C++ thingie is already written, and not badly coded... I did it just after the one you're currently seeing. Only thing is, I just haven't lifted the finger to upload it!

hyruleknight	Yay for bad grade curves, i can screw up the curve in almost any school in the US. i can't wait to try this thing of your's when the ubuntu CDs come in, i have to wait 4 weeks because my CD burn is shot
Saturday, 30 September 2006, 13:43
HoboBen	V2 out. It'd better work. If not, well freaking hell, I'll just hang myself.
Saturday, 30 September 2006, 14:18
hyruleknight	hey it works but the mouse control does not work
Saturday, 30 September 2006, 14:23
HoboBen	I think I forgot to put that in... JKIL does stuff. But, YAY it works!
