This code is the starting point of any 3d gamer's quest to design a 3d game. It will show you how to use openGL to load and display 3d models and show you basic keyboard input along with mouse input. Move around just like in UT or Half-Life.
Use mouse look, strafe and take a nice walk around this very very small city.
I got the textures working, i made a mistake...sorry. But since the file was almost 1mb with the textures as they were, i had to make em 256 color so they dont look all that pretty!
Make sre to extract the 3dworld folder to c:\windows\desktop otherwise the textures wont work! Sorry but this is the only way i could fix it.

Hey guys. If this doesnt load right, or it doesnt look right when it does load, let me know. I left out the material files due to size of the zip but the program seems to run with out them...go figure. Anyways, Please Please let me know if there are any problems. (If this comment was disrespectful, please report it.)
i can load it allright.. but, the sky is black, and the building are all white.. i can see a sillouette of the buildings though... the mouse movements look good.. this is a neat example i hope you can give me some pointers on how to load the graphix correctly

wow nice picture. i dont know anything about c/c++ but can you make a .exe with the "material files" so i can see how this looks like..... and than post a link where i can download the .exe.
Thanks alot.
Man, I love the picture its like a real 3d game. (If this comment was disrespectful, please report it.)
plz. upload the .zip i want to see how it looks with the textures. thx. alot. post the .zip or .exe link soon. plz. thx. (If this comment was disrespectful, please report it.)
i figured it out (i think) its looking for a LIB that doesnt exist located here: D:\nt\private\windows\opengl\toolkits\libaux it fails with this type: AUX_RGBImageRec something to do with IMAGE.C ?
(If this comment was disrespectful, please report it.)
haha ok i gotta stop posting.. this is too cool though... The model you sent wont work cause it doesnt store the pictures internally. Its looking for the pictures on my computer, and they dont exist. So i made my own model and the textures are in BMP format. But when i load the model i get a bunch of errors saying "invalid DIB format" and im using bmp's saved by MSPaint. What format of picture did you use to make your model? atleast im making advances.. now i actually get errors =)
so can you let me know what format the pictures are supposed to be in? thanks =) (If this comment was disrespectful, please report it.)

hey mouse make a .exe and link it to me. plz. i have visual c/c++ but dont know what the codes lines and errors mean..... lol plz. help me out... (If this comment was disrespectful, please report it.)
Hey guys, i uploaded the new zip with the textures. Sorry but they are in 256 colors due to zip size =( but you will get the idea. The sky is supposed to be black. I will update it tommorow with a sky and some fog if ya like. Let me know. Thanks for all your posts. (If this comment was disrespectful, please report it.)
YES!! THIS WORKED! woo whoo! thanks man this is too cool.. best code i have seen in a looong time! imma have fun with this =) (If this comment was disrespectful, please report it.)
ok if you want to see a working EXE go here: http://www.theblackhand.net/mouse/OpenGL.zip
Make sure you unzip this the correct way and retain the directory structure.
enjoy! (If this comment was disrespectful, please report it.)

well no wo whoo! for me!!!!!!!!!!!!! i need a .exe i dont know any visual c++ plzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz zzzzzzzzzzzzzzzz...................... help.........woo whooooooooo (If this comment was disrespectful, please report it.)
ok it works! but its black and white? i downloaded the fix version that is posted here, that doesn't work.
i also download the .exe form blackhand.net it works but no textures?
i tryed to put the images my the .exe and i also tryed to placed the default folder for the picures and still no texture.. any help? ?
o one more question: is there a way you can make this: - when i walk in to a building i dont go into it and get lost? Can you make me stop walking after i hit the wall.
anyway this is one of the best programs i have seen of PSC. (If this comment was disrespectful, please report it.)
there is something really wierd with how these type of models work. When you download the ZIP make sure you extract the exe to: c:\windows\desktop\ and the path of the BMPs and (If this comment was disrespectful, please report it.)
ops! scratch that! ok to get the ZIP to work do this: open it in WINZIP extract everything to: C:\windows\desktop\testaga\ that will get the models to work right. (it has to be that exact path, or the program wont find the BMPs and it will be black and white) im working on making this program load from its own resources and not use external resources so its a tad more portable.
this is a kick butt example though, thanks for sharing it with us =) (If this comment was disrespectful, please report it.)
make sure the model/bitmaps are in: C:\WINDOWS\Desktop\testaga\models and the EXE is on the desktop. it should work, i just tested it again (If this comment was disrespectful, please report it.)
The reason why this is such a pain to set up is cause the .MS3d file is a project file from the MilkShape3d program. It's not a real modle like from half life. This is like opening a MSVC++ .DSW file. If the files are in the wrong place, you get errors. Im thinking of writing a program that will store the bitmaps in the .md3d internally. Then rewrite this code to handle that. I think that will make this a little more portable.
good luck! (If this comment was disrespectful, please report it.)
as a matter of fact, im doing that now. so this will be the .MS3d model, but with the images stored within the .MS3d file, instead of just the paths. Maybe Dustin would like to work with me on making this into a newer model format? either way, im going to go nuts with this.. i have always wanted to do this stuff =) (If this comment was disrespectful, please report it.)
ok i downloaded the .zip i extracted it to C:\windows\desktop\testaga\ the bitmaps are in C:\windows\desktop\testaga\models and the exe is in C:\windows\desktop\testaga and it still doesnt show the bitmaps?
(If this comment was disrespectful, please report it.)
I dunno what this testtga stuff is, all u need ta do is extract the 3d world folder to your desktop not testtga! (If this comment was disrespectful, please report it.)
This is an EXCELLENT example, it worked for me just fine. If I understand this code well enough I could combine it with what I'm good at and make a pretty cool program. If I do this, you of course will get a lot of credit, I'm giving you an excellent vote. (If this comment was disrespectful, please report it.)
Alright, I'll be mailing this to the author anyway, but I'll post it here. To fix the problem with the textures loading, replace the function LoadGLTexture (in 3dSWorldMain.cpp) with this one (see below). It basically takes the filename off the path, and then re-allocates the path (ie. the project doesnt need to be in c:\windows\desktop\ or whatever).
I like though bud :) Nice work.
UPDATE: Ermm.. ok, I can't paste the function here, it makes my message too long. (If this comment was disrespectful, please report it.)
Well done for putting such amazing code up for free! Thx! I'm having a little trouble downloading it, but from the shot it seems just like the HL engine. With any luck it might download before i fall asleep... (If this comment was disrespectful, please report it.)
I am on Windows 2000 and there is no C:\windows\desktop there is only C:\Documents and Settings\Administrator\Desktop so this sample will not work on my computer. :( (If this comment was disrespectful, please report it.)
If you guys are having that "black and white" error, view the .msd or whatever file in there in text, you'll the see what directory this file looks for when trying to open those bitmaps! Hmmm, now i just need to make this program work faster, or maybe its just my 133Mhz computer! (If this comment was disrespectful, please report it.)
help!I was experimenting and want2 change the bitmaps but the program wont accept any different bitmaps besides the ones given.The new bitmap textures show up in MilkShape3d but when the program is compiled they are not there -just white!Whats going on? (If this comment was disrespectful, please report it.)
Thanks much for making this awesome code. Im using it as a 'self-tutorial' in OpenGL etc... I like it alot. 5 little planet thingies... (If this comment was disrespectful, please report it.)
Request: More info on file stuff.ms3d how to understand this binary file? please reply at vipers58@hotmail.com N.B:This file contains the bitmaps location. (If this comment was disrespectful, please report it.)
I have added to the game's model a small animation (destruction of one of the buildings). I need to know how to activate it in the c++ code. Please reply at vipers58@hotmail.com (If this comment was disrespectful, please report it.)
Hey, This is excellent! Great work :) I'd be perfect with collision detection though, and also if you can't turn upside down (You can only look straight up or down, not do a 360 ;)) So great work =D (If this comment was disrespectful, please report it.)
I've figured out this code and made an editor in VB. It works quite well, and makes it so that your files don't have to be in the proper directory as specified by the first comment. Unfortunately, I can't get it posted (I'm headed out for a week). Thank you to Dustin for posting this!

Yes the file is no longer there :(... Email it to me and ill host it on my site. (If this comment was disrespectful, please report it.)

I fixed it :) Go into the MilkshapeMoel.cpp and then choose the loadModelData() Method. Go to the Part where the Textures are loaded. Somewhere you will find:
after this you just paste: char dir[_MAX_PATH]; int t_char = '\\'; _getcwd( dir, _MAX_PATH ); strcat(dir, (If this comment was disrespectful, please report it.)
Recompile. Now it should search all BPM-Files in the models directory. If you like another one. It should be easy to change it. ========================== contact: www.intercompu.de (If this comment was disrespectful, please report it.)

I just wonder how you are going to determine collision detection. I tried something like this, but then I gave up and made it tilebased. Very good code. (If this comment was disrespectful, please report it.)

Pls add something like this at line 212 in MilkshapeModel.cpp to provide textures in every directory:
int j,k=0,s; for (k=0;ModelPath[k]!=0;k++) {m_pMaterials[i].m_pTextureFilename[k]=ModelPath[k];} for (s=0;pMaterial->m_texture[s++]!=0;) {if (pMaterial->m_texture[s]=='\\') {j=s;}} for (j=j;j++m_texture[j]);

4/24/2003 6:03:32 AM:
Alot of this code comes from here ...http://nehe.gamedev.net ...if you want it to work in any directory, you should be able to move the bmp files into the same place the exe file is, actually i edited the stuff.ms3d file in milkshake 3d too and changed the location of the bmp files. Do check out nehe website some excellent work in there, this would be a much better eg if it had collosion detection. (If this comment was disrespectful, please report it.)

I found out how you load the textures from a custom directory. HEre is where they are originally set to open from:
C:\WINDOWS\Desktop\3dWorld\models\
Yet if you open up the stuff.ms3d, and you find that text, you can change the path!!!
But i have a question, how do you create an ms3d file??? (If this comment was disrespectful, please report it.)
