Little VGA intro-source code.
───────────────────────────────────────────────────────────────────────────────
Created By : Vulture Total Files : 7
File Type : VGA-intro source Release Date : 17th of June 1995
Difficulty : Beginners level Filename : VGA-VUL1.ZIP

Well, here's another contribution to the large number of source-codes
available. It's a very simple little VGA intro including a 3D starfield,
a horizontal scroller and a palette fading. Enough for the beginning demo
coder to get started... (worked for me:))
The files included should be:
- boardz.exe => The executable
- boardz.asm => The full source
- numbers.dat => Data for starfield
- font.dat => Data for font
- make.bat => Makes the .exe
- vulture.txt => This text (wow:))
- file_id.diz => File description
Ok, there will probably be some other bbs-intros in this package too but
that's not a problem, I think. Hé, you downloaded thiz file so you are
obviously interested in demos anyway... :)
Right, on with the real stuff. The code is fully documented. And I mean
fully. Just check it out. I have described nearly everything there was to
describe in the .asm file. The mean reason I did this is because when I did
this simple thing, I had only just begun coding asm. And besides, I think
it's a good idea to comment this kinda stuff. It's hard enough as it is...:)
Well, since the code is documented, I will not explain things here. If you
have just a little experience coding asm, it won't be too hard to understand.
Only thing that might need some extra explanation is the font data. It's
acctualy very simple. Imagine having a font drawn on top of the screen.
What you have to do is save every pixel(color)value on the screen to a file.
Here is it in plain pascal. You should have a GetPixel function available.
For Y := 0 to 9 do { Save 10 lines of data }
Begin
For X := 0 to 319 do { Get the entire line }
Begin
Color := GetPixel(X,Y); { Get the color value }
Write(FileName,Color); { Write to file }
End;
End;
As you can see it's very simple indeed. Just play a little with it to get
it to work the way you want. You can use the same technique for entire
pictures. I've made a small Pascal program which does do this. Saves to a
pascal constant or assembly datafile. Might release it someday too...
The code concerning the 3D-starfield was originally from an example coded by
a guy named Draeden. A welknown American dude in the demo-scene. Only thing
I did was optimize a little, add a few things and comment the stuff. I don't
see any reason to do the whole starfield on my own when there are examples
available. Besides, if I code it myself, it would probably look a lot like
the examples anyway. Happened before... I know what I'm talking about... :))
Hmm, Outlaw is looking for a good gfx artist. If yar interested in creating
cewl things on the PC contact us at our distros. Or email: comma400@tem.nhl.nl
Don't hesitate to contact us, coz we like to chat with otha scene people... :)
Ok, that's all I have to say for now. Check out the .asm file and learn from
it. Don't just rip the code. That would be lame. But then again, if there
weren't any lamerz, cewl people wouldn't have anyone to loose their frusta-
tions on... hehe :)
Be seeing ya...
