QuakeC Source Code Licensing Status

Yes, it is out of the window for making a commercial game.

If you're just making a relatively obscure Quake mod, no one will care much.

Different worlds!

Though, how is taking their additions to a 1.06 base any worse than taking original 1.06 differences and adding it to 1.01?
Its not.

Thats why we didnt.

We took only the differences that are clearly in the Quakeworld source code, because Quakeworld has an official gpl license status.
If there were fixes in 1.06 that were not in quakeworld (and I only recall there being one) we left it out.
More specifically the only one I remember was the shub fix, which we came up with an original fix for, so no code copied.
The fix has the same effect of not allowing shub to die, but instead of healing her, we disallowed damaging her.

I spent a few hours today going thru the gpl-1.01, mostly client.qc for starters and recoding some fixes into it that arent in 1.06 or urqp for that matter

+ added a fix so players that connect during an intermission are properly put into the intermission
+ removed CHECKRULES and split it into two functions checkfrags and checktimelimit
+ cleaned up select spawn point, added a random spawn for deathmatch games
+ cleaned up PUTCLIENTINSERVER
+ some bitwise operations were flawed in player_jump and watermove
+ removed the body cue, and replaced it with a function similar to spawning gibs
+ changed sounds in player.qc to use ATTN_NORM so they arent global
+added a line to enable noexit 2 to obliterate the players touching an exit, noexit2 wasnt used anywhere else..

there truely is alot more to be done before im even calling this clean, but i can pm u the files to diff..

QW has noexit2 and random spawnspots.

You can do a lot of things to qc 1.01, but it pretty quickly turns into rook's mod instead of cleanqc.

HEhe ya I see what you mean. ;P

What is the definition of "cleanqc"? Some might rather have rook's mod.
Competing priorities: GPL purity, legacy compatibility, and actual debugged/efficient code.
The minimum environment also matters. Vanilla 1996 Quake and qc compiler, or a somewhat bugfixed Quake and fteqcc?

Is GPL really the best solution for a scripted language like this, sandboxed as it is to a specific engine and limited in syntax? Sometimes there is really only one way to do something in qc... well at least there are fewer license workarounds available than in C. It's a blessing and a curse. The accrued mass of unlicensed or vaguely licensed source/ snippits/ tutorals over the years is a factor. If it were all changed with a magic wand, would public domain, some sort of CCA, or something else be a better fit?

A 100% GPL QuakeC base code ought to be mostly targeted at moders who want to create new games, so removing any Quake IP related components is a must.
As a suggestion, the code could be split in folders like this:
a) singleplayer: a minimal set of code to implement gameplay against monsters (the basic AI, like ai_face(), ai_walk(), ai_run(), etc.);
b) cooperative: the bare bones to implement coop (mostly item pick code and some triggers behavior);
c) deathmatch: again, the minimal code to implement FFA, and maybe other gameplay types, like CTF and RA;
d) common: as the name says, all code that is shared by two or more subsets above. This includes but is not limited to doors, buttons, platforms, basic triggers, etc.

One part I think is problematic is the weapon/inventory code. The original code is messy and quite limited. In almost any mod I created I rewrote it to expand the number of slots, or the number of ammo types, or to support weapon groups or weapon leveling (or any combination of these), and I observed this in many other mods. Besides, one can argue that the original weapon behavior is part of the Quake IP itself, so while not illegal keeping it would be something in the gray area.

If you aim at that it would most likely end like usual. People have ideas what "must" be included, what is right, what is wrong, starting to refactor everything and in the end it gets abandoned.

Backporting / rewriting the vanilla 1.06 stuff to GPL seems the best idea. Then you can clean up from there.
