Doom 3 Source Code To Be Released This Year 210

Posted by timothy from the carmack-is-awesome-and-I-don't-even-play-games dept.
An anonymous reader writes "John Carmack just confirmed during his QuakeCon 2011 keynote that the source code to Doom 3 will be released this year. The source drop will follow the release of their Rage game in October. Carmack has also challenged other game developers to release their old source code."

But that was a long time ago when you speak to gamers about gaming rigs. 7 years may not seem like a long time, but think about it like this: how many video cards has a serious game addict been through since then, and how many games have surpassed Doom 3 in key ways? It was a fantastic game, and still is, but releasing the source code now, while a nice gesture, is not likely to spur any dramtic advances, since all legitimate developers

          Granted, a 6600GT is about twice as powerfull as the good old 9600XT (i had a 9600pro for a while, nice card that was), but a buddy of mine ran doom 3 quite well on a geforce 4 Ti, without Dx9 offcourse.

          • ... since it might still not be obvious, from man calloc [die.net]:

            calloc() allocates memory for an array of nmemb elements of size bytes each and returns a pointer to the allocated memory. The memory is set to zero.

            What's more important is that calloc is faster than malloc+memset for a number of reasons, most notably that OS can pre-zero free memory blocks while idling. So, given Carmack's love for micro-optimizations, it would be sacrilegious to suggest that he'd use something as comparatively inefficient as memset(0) in this context.

            • The reason it's not funny is that the frame buffer is a static memory allocation. It is in VRAM and is not allocated with malloc().

      Unlike most modern games, were you have a clear separation of the engine from the ".wads/maps/music/textures/game files/etc.", in those early games, the game itself was interewined in the code.

      If you see all the FOSS releases idSW has made over the years, the ENGINE soruce code gets the FOSS treatment, but the copyright of the game files themselves remains in the hands of the company, therefore, you still need to buy a copy of the game to play it legaly, even if you use a FOSS engine, or a port (my case on a MacBook).

      So, most likey, they will not release that older code, not because they lost the source, but because releasing it in that case is to give away the game for free...

      Cheers

      • I've always misunderstood the open sourcing carmack likes to do, but now I get it, he's not giving away the game, he's just allowing others to tinker with the game engine.

    It's a shame that a lot of old games (including DOS games, circa 1995) have been consigned to the graveyard of dead software, where they can't be ported/maintained because they have no sources and need emulation, they can't be bought except for second/third/20th-hand, they can't be copied/preserved because of copyright. It's shameful, really. I feel quite angry about that tbh, and I'm delighted to see game creators make an effort to release their code.

    I sometimes see people arguing that releasing the code is impossible because some parts are based on proprietary code they don't have the rights to. I wish they would just cut that code out and release the rest. There are a lot of eager fans out there who would be very happy to rewrite that code and even develop drop-in open-source replacements that can be reused for other ports (yes, even entire game engines). Let's not let old games end up like old films, rotting away in the archives of underfunded libraries without anyone knowing they ever existed.
