GNU is Not Unix 34

Nushio writes "Continuing with the Liberated Pixel Cup coverage: The Art Competition recently finished, and the code portion of the Liberated Pixel Cup has begun. There are some pretty awesome tilesets and assets available for game makers to use, and still plenty of time to make Free Software Games." Entries are due by July 31st. Any Slashdot readers planning on giving it a shot?

I was just thinking about something similar... (4, Interesting)

Simon Brooke (45012) | more than 2 years ago | (#40541879)

I'm working in 3d, and as near photo-realistic as I can get, rather than 2d cute cartoony stuff. You can get a long way with tools like MakeHuman [makehuman.org] , but there isn't (yet) and equivalent MakeCamel project, and my game needs camels... Given that what I want to do is fairly photo-realistic, I would have thought that the assets I want are also wanted by makers of lots of other games (OK, maybe not the camels) and that what's needed is a sort of Creative Commons directory of game assets.

Mind you, this competition is a great start and worthy of support.

And browsing the links from tha original article [slashdot.org] , it looks like Open Game Art [opengameart.org] is just what I want!

Is that really a good model database? It seems to have only so few models, f.e a search with a "human" tag only gives two pages, a total of 30 models and even much less complete ones.
I'm not that impressed, that's as much as one open source game, I bet 0ad alone has more f.e.

I have a feeling that most games don't really post their art here, f.e. it doesn't seem like there's anything here from any of the spring games, and there's a lot of games with high quality models.

OGA founder here.

3D models are difficult to deal with. For some reason 3D art in general tends to have a lot of sticky licensing problems. This is partly because the most popular texture archive on the internet has a license that prevents redistribution of their textures. As such, a lot of models people would otherwise want to upload aren't acceptable in free and open source games, so we can't accept them on OGA.

We've started our own texture archive [opengameart.org] as a way to hopefully deal with this in the long term, but it's going to take some time.

The other problem is that 3D art costs vastly more to make than 2D art. We commission a lot of 2D stuff, but we just don't have the budget for any worthwhile 3D commissions.

the most popular texture archive on the internet has a license that prevents redistribution of their textures.

You could start an archive of mostly untextured meshes for use in, say, a cel-shaded game. Vertex painting goes a long way in cartoonish styles, as Nintendo's N64 era games show. Are there really any textures on Mario from Super Mario 64 other than his face and the M badge on his cap?

3D art costs vastly more to make than 2D art

More money? I don't understand; I thought there was Blender. More time? I don't understand; I thought at least low-detail 3D art could be drawn once, then given an armature and posed into any position instead of having to manually redraw each frame of the character's animation, and that's why the sprites of Donkey Kong Country 1-3, Uniracers, and Killer Instinct were built as CGI and rendered to sprites.

OpenGameArt supports other styles and formats as well, just not for this competition. They could definitely use some 3d camels.

All art created for the contest is released under two licences. the creative common is easy, but i can't seem to understand a word of gplv3.

Say I want to use some of this art for a game. What can I do? (outside of the contest, the rules for it are clear)
Can I sell my game?
Am I required distribute all art I create and the source code under the same licences?

Re:About licences (2)

Nushio (951488) | more than 2 years ago | (#40542141)

If you choose to use the GPL license for art, all further modifications to said art will be done under the GPL License.

If someone were to grab your modified art, they'd have to use the GPL License as well.

On the other hand, CC-By-SA Means that you can use it on a closed-source game, however the art being CC-By-SA Means that your assets (and any modifications you make to them) can be used by other game devs.

Re:About licences (2)

Rhaban (987410) | more than 2 years ago | (#40542183)

So I can make the game as closed as I want, but I must release any art I do based ont GPL art?

Re:About licences (1)

Nushio (951488) | more than 2 years ago | (#40542225)

If the art is GPL, the code must be GPL as well, (which means it can't be closed).
The art is dual-licensed though, which means it's up to you to choose CC-By-SA 3 or GPLv3, at your convenience.

Re:About licences (2)

JonySuede (1908576) | more than 2 years ago | (#40542973)

What happen if you load a gpl art image in Photoshop are you in license violation? No: why is the loading of the art image by the game engine is any different. Yes : wow what a nice conundrum.

Re:About licences (1)

Lussarn (105276) | more than 2 years ago | (#40543073)

GPL is a distribution license, not a use license (EULAs for example). You can do what you want as long as you don't distribute.

Re:About licences (1)

JonySuede (1908576) | more than 2 years ago | (#40543305)

Do you know if can you package the image loading and manipulation code as dual license LGPL/GPL code and link your game to your imaging library ?

Those questions are theoretical*1 as I do not plan to make a game neither open nor closed !

Re:About licences (0)

Anonymous Coward | more than 2 years ago | (#40545011)

Such blatan troll but I'll bite. Yes, assuming loader has to be GPLed in that case can you *link* a GPL library into non-GPL program? A rhetoric question, I know, but that's the level of your question and one of the reasons why I called you a troll.

Re:About licences (1)

julesh (229690) | more than 2 years ago | (#40545701)

The relevant question is whether your game is a derivative work of the art, that is did the details of the available artwork have any influence over your code as you wrote it? If so, then there's certainly grounds to believe that you would have to release your code under GPL if the artwork is GPL. Otherwise, not so much. The details of how you load it are irrelevant, it's what you do with it that counts.

Re:About licences (1)

JonySuede (1908576) | more than 2 years ago | (#40546253)

thanks; that makes sense to me ;
even if it is not legal advice and blahblahblah ...

Re:About licences (0)

Nushio (951488) | more than 2 years ago | (#40543075)

I thought the standard slashdot post contained the disclaimer "I am not a lawyer, this is not legal advice".

Re:About licences (1)

JonySuede (1908576) | more than 2 years ago | (#40543217)

Since when a question is considered an advise ? I did not use the Socratic method to teach a concept. I just asked a question assuming something that I should not have assumed : GPL == EULA. I learned that it was false as Lussarn (backed by the FSF site) told me.

Re:About licences (1)

Nushio (951488) | more than 2 years ago | (#40543565)

I'm just saying that my interpretation of the GPL may be wrong and should not be taken as legal advice.

From what I understand, if you use GPL Art on a non-free game, and redistribute the gpl art with the game, you're in violation of the gpl license.

hendrikboom (1001110) | more than 2 years ago | (#40545985)

It's a rule that the code has to be GPL. The art can has to be dual licenced, GPL and a specific creative commons license.

Re:About licences (1)

hendrikboom (1001110) | more than 2 years ago | (#40546065)

If you created is, and you hold the copyright, you an do anything you want with it. You can give it away, you can licence it to others under any number of licenses you want, it's yours.

But if you use others' art or code in your project, that art is theirs, and you have to follow the rules they sest. In particular, if their code is GPL, you cn only distribute binary versions of your program under the GPL, which means you have to release source code.

If you release your own code under the GPL, anyone else can do what they want with it, as long as they distribute it under GPL. But it's still yours, and you can release it under any number of other licenses if you want, and you can include it in your commercial software if you wish.

None of this prohibits you from selling it. But be aware that if it was released under GPL, anyone else can sell it too, if they wish. You may find you have stiff competition, which can keep the price low.

I was in the competition . . . (2)

Mitchell314 (1576581) | more than 2 years ago | (#40542187)

But unfortunately my computer broke a while back, and buying a new one is waaaaaaaaaay out of the question. :/

Though I still am working on the server side of the game for the competition, since I can still can operate it with a CLI. Probably won't be done for submission, but it's something I want to work on anyways :D. I'm a CS student in need of coding practice anyways, and I'm one of the crazy mofo's trying to write it all in c.

Slashdot readers! (-1, Offtopic)

girlintraining (1395911) | more than 2 years ago | (#40542405)

Any Slashdot readers planning on giving it a shot?

No. They still think they have a chance with Natalie Portman and are spending the holiday building creepy shrines in their basements to unrequited love. I only know this because I've seen numerous trails of stale cheetoes leading away from supermarkets and gas stations in the past few days. There's also been an uptick in empty bottles of hipster drinks and refillable starbucks... but I'm pretty sure that's only because it's really hot outside and they're sweating balls in their trendy skinny jeans and huge horn-rimmed glasses. Cattle mutilations are also up this week... just sayin'.

hendrikboom (1001110) | more than 2 years ago | (#40546133)

I'm thinking of trying it. It's time to learn another language. I don't know what kind of a game it'll be, or even whether it'll be playable, but it'll be written in ocaml (or maybe Gambit Scheme. Scheme has changed a lot since I last was involved with it back in the 80's.).
It'll probably be a 3D game, with the environment entirely built out of their 2D tiles. But I do have more important things to do, so I can't apply as much effort to this project as I'd like.

Feel free to look on the liberated pixel cup in a month to see if I produced anything or just had fun coding.

Might give it a go... (2)

madmarcel (610409) | more than 2 years ago | (#40546977)

Stuck at home, off work sick, so I have some time.
Downloading the art assets now and we'll see if I can find some inspiration in that.

It doesn't look like they got a lot of art entries though...we'll see.
