QuakeC Source Code Licensing Status
Re: QuakeC Source Code Licensing Status
Well, then in this case people who want to make commercial game using DP and Quake's QuakeC can do it without releasing their QuakeC source (doesn't make much sense, but if they want to it's an option).
Re: QuakeC Source Code Licensing Status
What makes you think so? Copyright is implicit to any work (Berne Convention).

Re: QuakeC Source Code Licensing Status
Closed sources engine license copyright belongs to iD Software, however, licensee doesn't release source code. Same thing here - id Software is still the author of the code, yet the license (or absence of it) doesn't force you to release the source. You would have to mention in credits that 1.06 was used as base, however, you don't have to release it.
Re: QuakeC Source Code Licensing Status
Well, what rights do you have to use the source for anything not Quake?

Re: QuakeC Source Code Licensing Status
It's about license, not about copyright. License defines what I can use it for and what I can't use it for. Copyright delegates authority (who is the entity that made this). I still have to mention all copyrights of GPL app regardless where I use it, even if I changed the title of the GPL app.
So, I have any right to use QuakeC for whatever I want.

Re: QuakeC Source Code Licensing Status
This is about the QuakeC source of id1. If there was no license allowing you to use it, then there is no license allowing you to use it. I am not sure what you are talking about.
id released the source for people to use but forgot to specify a good free license. Technically you do not have a right to use it.
The entity holding the copyright can decide to release its works under a license of its choice. Unless that happens, you have no right to assume so.
Now, this is getting way out of hand. id wanted you to use it and so you should. But if you want to base some commercial work on it, you should be aware that you have no legal right to do so.
(By you I don't mean you of course, motorsep.)

Re: QuakeC Source Code Licensing Status
For once, QuakeC is not a piece of software. Technically, it's an assets from the game. So you can't even redistribute it for free (just like you can't redistribute art assets of Quake or any other game).
However:
http://en.wikipedia.org/wiki/License-free_software
http://www.law.cornell.edu/uscode/text/17/117
One can simply rewrite QuakeC using 1.06 as a reference, a white paper so to speak, and be free from the burden of dealing with license-free non-software thing.
The whole topic is moot, because no one gives a crap about QuakeC being used in commercial projects - we are heading into 2014, there is idTech 5.x roaming around. So unless a game that uses Quake engine derivative and QuakeC code will beat sales of Rage or any other idSftware/Beth games, chances are slim to none that Zenimax will care for what QuakeC code developer used (or if GPL Quake derivative engine is violating GPL license).

The linked WP article is terrible (yet underlines the problem) and I am not sure what you are trying to say with the other one as I don't speak lawyerish and I don't know how it is related.

Re: QuakeC Source Code Licensing Status
If you don't speak lawyer'ish, maybe you should refrain from any speculations on the subject? Maybe you should sod off?
Re: QuakeC Source Code Licensing Status
I do not understand how http://www.law.cornell.edu/uscode/text/17/117 is in any way relevant. If it is and you could elaborate, I would be grateful since in that case I would not have found the relevance hidden inside the lawyerspeak.
Just to make sure no one takes your words as plain truth: You can use the GPL'd 1.01 QuakeC Quake source code just fine for anything you like under the terms of the license. It is not an art asset (unless you want to go philosophical) but perfectly normal software source code. You can use it to create Superreal Tourney 2014 or cat it to /dev/dsp as music, perfectly fine.

Re: QuakeC Source Code Licensing Status
QuakeC is in fact an asset. You can't compile it into a lib or binary. It's a scripting language that can't exist outside of Quake engine. DP engine can run just fine without QuakeC being present.

QIP Ultimate Regular Quake Patch on quaketastic urqp106a.zip
Re: QuakeC Source Code Licensing Status
I'm just now comparing 1.01 and 1.06 using diff.
By and large, the code is identical. The changes:
- client.qc has some changes in the spawnpoint selection and obituaries code and misc. minor changes (I assume QW has the latest version though)
- items.qc has some minor differences and has weapons missing from Dropbackpack() BUT the GPL QW source has the full function
- weapons.qc in v101 lacks some minor fixes and does not have CycleWeaponReverseCommand, but again the QW source has it
There might be one or two other small changes, but... that's it. And remember that any commercial game is going to rip out the monsters, weapons and items anyway and replace them. Same goes for the obituaries and probably even the multiplayer stuff. Hence changes in monster code between 1.01 and 1.06 are completely irrelevant anyway. All the core stuff you're gonna need for a new game is in 1.01 and Quakeworld, which are GPL.
So,
1) The changes between 1.01 and 1.06 are absolutely minor. Anyone could fix up 1.01 to make a game with in the course of an evening. And a case for GPL violation if you used 1.06 would be exceedingly hard to make because the codebases are almost identical.
2) The GPL QuakeWorld source has some of the stuff that is absent from 1.01 such as Cycleweaponreversecommand().
3) The sensible choice for anyone making a commercial Quake 1 based game is to simply use the GPL licensed 1.01, add some stuff from the GPL licensed QW if necessary, and release their source, unless they're writing everything themselves.
But like I said, it would be exceedingly hard to tell if a total conversion was based on 1.01 or 1.06 to begin with, since they're almost identical.

Re: QuakeC Source Code Licensing Status
Took the v1.01 source, fixed norefs, uninitialized variables, empty return statements, duplicate frame macros and other minor inconsistancies.
Also added dropBackpack and CycleWeaponReverseCommand directly from Quakeworld's gpl'd source code to preserve
the gpl integrity of v1.01 by not pasting from the unlicensed v1.06.
Thanks to gb for that idea.
The result is a legally gpl quake source which is very very close to v1.06.
gb and I will be looking in the next few days for anything else v1.01 left out that Quakeworld has to offer.

Re: QuakeC Source Code Licensing Status
Great job! Although I think if you used 1.06 and put GPL headers into the source files, no one at Zenimax would give a damn
