Just a suggestion: I would greatly appreciate it, and I sure others would too, if the next, or a tutorial sometime in the future, was on 2D programming. I think it should just be a tutorial to make a 2D charecter walking around the screen. I have tried unsuccessfuly many times I hate to say that, too. There are tons of 3D OpenGL tutorials, and two 2D ones, and they arent very helpful for making RPG''s. I read through your 21st tutorial and it helped me a bit, but I still cant do it. I am reading Kevin and Daves "OpenGL Game Programming" book, and it really breifly goe over some 2D stuff. It mainly only teaches you how to load the bitmap, and then use it as a texture on a terrain or model. I cant figure out how to make the texture move, as a quad with a bitmap in it. Anyway, I am goign to keep trying, but I think it would be helpful if you made a tutorial for 2D in the future. Thank you for your time.

If you''re looking for basic 2D tutorials (basic animation, page flipping, and other such basic techniques) you might want to check out some old DOS tutorials. OpenGL will handle most of these things (like double-buffering and such) for you but some of the concepts still apply. And alot of DOS tutorials are focused on either neat graphical gimmicks or full fledged RPG''s so it might be worth looking into.

Try something like www.hugi.de and read up on the older articles from 1997 and earlier.

Personally I think these new Game Programming tutorials are a god-send. They''re very, very useful for getting a head start on your own engine and I hope to see many more in the future.

I think you''ll fnid that NeHe restricts the site to Game programming with OpenGL.

2D stuff has been done and then done again... you''ll find some of the classic links around, and there have been some more recent things on how to do it with DX7 and even OpenGL.

Hey... 2D OGL my favourite thing...

Learning 2D using OGL is easy.
The basics are ::

Ortho View
Translation and Rotation

Finish...
The others apply for standard 2D functions (as other 2d engines). The only problem is texturing, you may need to break your texture to small squares !!

You might also leave the ortho view to make some interesting effects (Ever seen Digimon ? Look at the Intro/Ending, it has lot''s of 2D images flying and rotating around, looks GREAT)

My trouble is I am a neat person and the creators of windows deserve to bwe tortured The programming is messy enough for me, I really dont want to add a code wth function that talke 40 parameters, I am not used to it. And I am having alot of trouble, even if it seems like I am doing it right. i have searched the net for tutotrials for at least 20 days now, and NeHes were the closest I got. If anyone has some sample source of a OpenGL 2D RPG,please send me a link, or the cpp file. I would rally appreciate it.

btw: I wont use direct x, its too messy for me. besides that, I dont like microsoft and its bad enough I use windows :o
