1 2This is the complete source code for winquake, glquake, quakeworld, and 3glquakeworld. 4 5The projects have been tested with visual C++ 6.0, but masm is also required 6to build the assembly language files. It is possible to change a #define and 7build with only C code, but the software rendering versions lose almost half 8its speed. The OpenGL versions will not be effected very much. The 9gas2masm tool was created to allow us to use the same source for the dos, 10linux, and windows versions, but I don't really recommend anyone mess 11with the asm code. 12 13The original dos version of Quake should also be buildable from these 14sources, but we didn't bother trying. 15 16The code is all licensed under the terms of the GPL (gnu public license). 17You should read the entire license, but the gist of it is that you can do 18anything you want with the code, including sell your new version. The catch 19is that if you distribute new binary versions, you are required to make the 20entire source code available for free to everyone. 21 22Our previous code releases have been under licenses that preclude 23commercial exploitation, but have no clause forcing sharing of source code. 24There have been some unfortunate losses to the community as a result of 25mod teams keeping their sources closed (and sometimes losing them). If 26you are going to publicly release modified versions of this code, you must 27also make source code available. I would encourage teams to even go a step 28farther and investigate using public CVS servers for development where 29possible. 30 31The primary intent of this release is for entertainment and educational 32purposes, but the GPL does allow commercial exploitation if you obey the 33full license. If you want to do something commercial and you just can't bear 34to have your source changes released, we could still negotiate a separate 35license agreement (for $$$), but I would encourage you to just live with the 36GPL. 37 38All of the Quake data files remain copyrighted and licensed under the 39original terms, so you cannot redistribute data from the original game, but if 40you do a true total conversion, you can create a standalone game based on 41this code. 42 43I will see about having the license changed on the shareware episode of 44quake to allow it to be duplicated more freely (for linux distributions, for 45example), but I can't give a timeframe for it. You can still download one of 46the original quake demos and use that data with the code, but there are 47restrictions on the redistribution of the demo data. 48 49If you never actually bought a complete version of Quake, you might want 50to rummage around in a local software bargain bin for one of the originals, 51or perhaps find a copy of the "Quake: the offering" boxed set with both 52mission packs. 53 54Thanks to Dave "Zoid" Kirsh and Robert Duffy for doing the grunt work of 55building this release. 56 57John Carmack 58Id Software 59 60 61
