Does the Doom3 source code includes RoE? There's no Mac port of RoE so now it could be possible to port it.

prg3182• 15 years ago

The idtech4 source code release does not include any game data whatsoever (only the game engine source code), so the short answer to your question is "no".

barrettcolin2• 15 years ago

The slightly longer and more correct answer is the source release contains the game engine source and the Doom 3 and RoE game DLL source. The Doom 3/RoE game data is still required.

barrettcolin2• 15 years ago

It includes the source code for the expansion pack game dll (in d3xp). You'll still need the original RoE assets (when I went to install them on Windows, the installer crapped out because I wasn't on Windows 2000 or XP, but you can just copy them from a directory on the CD- they're in a d3xp directory or something like that).

Why not just get these changes upstream?

Also, instead of forking it on GitHub, he just reuploaded the whole thing again (https://github.com/fabiensanglard/Doom3-for-MacOSX-) so that others cannot easily merge these changes. And neither in his repo nor in his post, there is a reference to the original repo (https://github.com/TTimo/doom3.gpl).

Also, on the original repo, there were already a few fixes for Xcode4 and there is also a pull request with further fixes (https://github.com/TTimo/doom3.gpl/pull/13). I haven't checked it myself but it might actually work already.

Btw., further development is probably going on here: http://www.iodoom3.org/ (http://news.ycombinator.com/item?id=3277150) (https://github.com/TimeDoctor/iodoom3)

They can easily merge those changes. You just have to use the git command line. It's possible to merge in a separate repo. Like so:

  git remote add d3mac https://github.com/fabiensanglard/Doom3-for-MacOSX-.git
  git fetch d3mac
  git merge d3mac/master

albertzeyer2• 15 years ago

No, you cannot do that easily the way you described:

    $ git fetch d3mac
    warning: no common commits
    $ git merge d3mac/master
    [ many many conflicts ... ]
    CONFLICT (add/add): Merge conflict in neo/ui/Winvar.h
    Automatic merge failed; fix conflicts and then commit the result.

He responded in his comments:

> If not, the fork will remain buried as a Pull Request with no visibility at all.

Which is loads of bullshit. By design git is decentralized so upstream is a mere convention, where usually the closest to upstream is either the original author's repository or the most active repository.

I was actually writing a blog post on this issue as we speak. GitHub's approach is broken to how they handle forks. It's a long post but I updated it to mention your comment here.

"brew install doom3" would be sweet.

aw3c2• 15 years ago

No idea what brew is but be aware that the game media is not free.

Sure. Linux distributions used to deal with this all the time, you could install the old doom, quake packages, etc., and you'd have to provide your own game-media - but the package manager would install the linux-native game binaries for you.

endlessvoid943• 15 years ago

As someone who isn't familiar with game development, could someone explain what exactly is and isn't free? What happens if I try to run the game without the Doom3 media?

How might one go about making their own media for the game? Does it even make sense to do so? How tightly coupled is the released source code to the media?

wladimir2• 15 years ago

could someone explain what exactly is and isn't free?

The source to the game executable (rendering, script interpreter, physics, pathfinding) is free and released under GPL. The assets, however, such as scripts, textures, shaders are still under the original commercial license.

It is certainly possible to make your own media for the game; it will be a lot of work, but arguably less work than writing your own game engine AND making the assets. It makes sense because the Doom3 engine is very flexible and you can do a lot with it, some of which has already been done in the form of mods (as the SDK has been available for a long time).

endlessvoid943• 15 years ago

Thanks.

So if I wanted, theoretically, to modify the mechanics of the game, how would I do that with "assets"? For example, if I wanted to add "magic" or something (like mana from diablo 2), and perhaps change the way "score" is calculated, is that part of an asset as well?

Do engines provide a DSL for making games? I guess that's my question. It seems like media assets only allow you to reskin Doom instead of making a new kind of game.

nknight• 15 years ago

id Software is, to no small degree, in the business of making game engines, not just games. Their engines are quite deliberately decoupled from data so they can license them to other companies for their own games.

You'd use a combination of general-purpose tools (Maya, Blender, Photoshop, GIMP), and more specialized tools (like Radiant for map making) to create original media assets.

Custom gameplay is achieved with a combination of a built-in scripting language and modifying a separately-loaded C++ library that encompasses most of what really constitutes the "game" beyond the core graphics engine. The game library appears to be included in the GPL3 release, and was previously available as part of the publicly-available SDK for modders.

You could take this code base and start adding your own custom models, textures, and maps, and have a workable game as-is.

Thanks, this was a great explanation.

cool job！

lanstein2• 15 years ago

My main issue is that I don't see why he's using a Das Keyboard with the letters on the keys. Doesn't that defeat the point?

dfc• 15 years ago

They sell one with letters on the keys. I think its called the professional model. I always thought the point of das keyboards was the tactile button presses...

lanstein2• 15 years ago

I suppose. I always assumed the point was to be obnoxious - I know that's why my brother bought one.

kxs• 15 years ago

Sorry to hijack, but has anyone been able to do similar for wolfenstein: enemy territory (on OS X Lion)?
