@CyraX

Ever tried TGA??
They will have all that stuff embedded directly into the image.
It will greately ease your development time.

Can you explain? As I know OpenGL doesn’t support image formats
Can you tell me how to use TGA in OpenGL and what exactly it will give me?

This is not exactly three, it is object which should particulary hide another objects. It is small and textures are created via RGB arrays. It is possible to use RGBA array and A-value 1 for all pixels that should be transparent? I think this should work (you say texture should be of the type GL_RGBA).
Thank you for the help

Hi!

You can create a tree, where each branch is a triangle or a quad plane and the
texture is of the type GL_RGBA.
Then, if you turn on GL_BLEND and provide the proper blending function
at glGlendFunc() the pixels with alpha > 0 will be more or less
transparent.
But this means, you have to provide an alpha channel in your texture image.
Most image manipulation programs can handle transparency. I suggest to
use The Gimp, its free and very powerful.

I hope this helps a bit

Greetings
Stefan

Currently I’m writting a game. It will be Open-source - I whink games should be kept open-source for many reasons. Game is using OpenGL for graphics and have level-editor included. I’m working in a team - I’m writting the game and the main code of the level editor, another person is making textures and writting parts of level editor :)

The whole forum is here to help (in the first place).
However you should understand that help is not doing ur assignment. You must first start coding and understanding the concepts - No spoon feeding here. We would like to train Hackers in Grafix. Try to ask you questions and we will give you answers.

Get started:
In OGL your bible/Quran/Gita/Granth Sahib == Red Book. You will find the online version of it too.
For some example OS related code - nehe.gamedev.net

If you want any other help - ask. Smart guyz ask for help.
I should however warn you - THIS IS NOT A PLACE TO POST YOUR ASSIGNMENT and ask us to do it.

well, i think on NeHe, you’ll find the needed code’s.. espencially code for a rotating cube is used in a lot of his tutorials (see tutorial .. 5 i think..)

for the sphere, he uses quadrics.. you can use other methods, but they are rather simple.. you’ll find it in another tut..

rotating:
check glRotatef(…)

scaling:
check glScalef(…)

moving:
check glTranslatef(…)

If you want to see/critic a game(s) then you have to first look @ what type of games they are.
Broadly you will find:
First Person Shooter (FPS) - Quake series, Unreal ,doom
Simulation :
|_ Space Simulation - Descent, Star Lancer
|_ Flight - M$ Flight Simulator, F22 Raptor, F16 etc; Commanche Series
|_ Car/Drive - NFS

RPG :
|_ Dungeon Siege
Arcade:
|_ Tekken series, Mortal Kombat
Scroll Games also RPG:
|_ Age of Kings/Empires, Command && Conquer series, Simcity, Caesar, Diablo
Third Person:
|_ Tomb Raider, Indiana Jones

@ one estimate you might be having more than 10 -20 genres today. So go ahead and work about with the history of games. Today’s games - well you will get lotsa help - but I guess you should first look @ the games that started it all - Mario, Contra etc; Then come to the Classic Doom, Wolfenstein. Then you might end up with the today’s gamez.
I think you will have a balanced act with:
StartX: Mario -
New Ideas: Doom
AI: Deus Ex/Max Payne/Half Life/ Thief - order of precedence Thief being best @ AI (IMHO)

were going to do like a case study on them

and put down what made the game work out; he hasn’t told us a whole lot so far. but were going to tell what each part does
then after all this were going to make a little program using different specs to have a demo of each game

baldurk: thanks for the correction

craig: how about giving us a little bit more info? we [or maybe just me] can’t help with so little information.

:yes:

@donBerto

before I (or anyone else) provides answers

can you tell us more about the assignment? I don’t understand the “find games that have actually been sold…”

I didn’t think nehe had zelda, i thought it was that person that linked through nehe. i could be wrong…

check out:

freespace [links provided here somewhere]
ID software

can think of anything else on the top of my head.

he wants us to use games that have actually made it onto the market
like tetris, zelda, roms and such

NeHe never sold zelda, so that wouldn’t really count.

Also, ID Software’s website is idsoftware.com not id.com

The source code for Quake II was released under the GNU - GPL.
So ,that’s free software too :) (free as in free speech)

Hi!

The source of “Doom” was released, the source
“Descent” (very good game!) was released, too.
I think the source of Quake is free, too.

I once looked into the source of Descent and they did
a great job hiding the interesting parts in their
code *g*. So much for the clarity of the code.
The developers flamed each other in the code,
too. It was quite funny to read.

Greetings
Stefan

I was doing something wrong before. When I read your previous reply, I looked at it again and I started using -A; but it wasn’t working. I tried it today, and ‘poof’ it works. Tried it several times and now it is working fine. Thanks
