John Carmack heeft de volledige source van Quake en varianten (WinQuake, GLQuake, QuakeWorld, GLQuakeWorld) onder de GNU Public License gereleased. De code kan neergehaalt worden van id's FTP site of van de mirror bij Walnut Creek:This is the complete source code for winquake, glquake, quakeworld, and glquakeworld. The projects have been tested with visual C++ 6.0, but masm is also required to build the a embly language files. It is po ible to change a #define and build with only C code, but the software rendering versions lose almost half its speed. The OpenGL versions will not be effected very much. The gas2masm tool was created to allow us to use the same source for the dos, linux, and windows versions, but I don't really recommend anyone me with the asm code. The original dos version of Quake should also be buildable from these sources, but we didn't bother trying. The code is all licensed under the terms of the GPL (gnu public license). You should read the entire license, but the gist of it is that you can do anything you want with the code, including sell your new version. The catch is that if you distribute new binary versions, you are required to make the entire source code available rce code available for free to everyone.[break] Verder heeft Jonh in een .plan update laten weten dat de release van de Q3 game code is vertraagd: [/break]The Q3 game source code is getting pushed back a bit because we had to do some rearranging in the current codebase to facilitate the release, and we don't want to release in-progre code before the official binary point release. We still have a Christmas present for the coders, though: http://www.idsoftware.com/q1source/Happy holidays!
