Opengameart.org is very proud to announce that we are collaborating with the Free Software Foundation and the Creative Commons to bring you the Liberated Pixel Cup, a two month long summer contest about creating a consistent set of art and then making awesome games with it!



As you might imagine, this is big news for OGA -- there's no better way for us to further our mission of bringing artists and developers together to make awesome free and open source games than having the opportunity to work together with the CC and the FSF towards making that happen!

So, what are you waiting for?  Go, check out the site, and join us on IRC at #liberatedpixelcup on irc.freenode.net

Looks good.

This is a bit overboard, but passable, though:

First off, lest people walk away from this with a gigantic misconception about the rules, I need to quote some additional context:

Just to be clear, we cannot accept games that require any of the following:  Flash, Silverlight, XNA, Unity, Windows, MacOS (or OSX), iOS, the official Oracle JVM, or similar.  It is perfectly acceptable if your game runs on any of these platforms, but it must also work on an open platform [...]

(Honestly, I'd really prefer if you edit your post to include that bit, as people who don't go to the site and actually read the rules will see it and get the wrong impression.)

The point isn't to say that your game isn't allowed to run on Windows; it's that it must run on a completely free-as-in-freedom platform in addition to any other platforms that it runs on.  This isn't about restricting developers, it's about not restricting users.  It's extremely likely that any game entered into the contest will be easy to port to Windows, and I'm suspect that many entrants will release a Windows binary.  But, given that the contest is being run by three free culture organizations for the purpose of adding to the commons, it would be silly of us to accept entries that require people to run non-libre software.

I should also point out that the contest is being funded by donors who support this cause.  People like moi (above) who dislike the rules for whatever reason are completely free not to participate. Smiley

No, not just HTML5.  There are a plenty of other options, but I get the feeling that this particular contest may be a bit too far outside of your comfort zone.

You are, as I said, welcome to participate or not.  There are plenty of other game making contests out there, many of them specifically for flash.  I would recommend one of those instead if that's what you prefer. Smiley

An example of the sort of possible entries are
  • python using pygame or similar
  • C/C++ using SDL
  • HTML 5

Remember also that it doesnt say that it can't be written in Java, only that it mustn't require the official Oracle JVM. I'm guessing that it's perfectly acceptable in the competion to write the game in Java as long as it can run on the OpenJDK platform, rather than requiring the Oracle one.

And of course you could just use Python, C++, Perl, or any other language with open source implementations. It's not as restrictive as it sounds.

Does it also mean that your source code must be open source? :/

I'm guessing it does mean that- it's being run partly by the FSF after all.

I think this is a great idea and I hope I find time to participate (although I doubt it; maybe next year?). Which reminds me I must find some time to clean up my java4k source code and release that.

Limitations would not affect me much, but I think that is a bad thing. A very fun thing about competitions is forcing myself to do things I normally do not do, which is great for inspiration and also a sure way to learn something new.

Just a note, this is happening right now. Seems like they kind of info-dumped and left these a few places without following up. I'll break it down because this compo has some pretty substantial prizes  Hand Money Left, and I know there is some REALLY good talent on this forum that could use the exposure.


Art Competition (June 1st - June 30th)
$1500 USD: grand prize (team or individual)
$500 USD: secondary prize, individual only
$500 USD: secondary prize, individual only

Coding Competition (July 1st - July 31st)
$1500 USD: grand prize (team or individual)
$500 USD: secondary prize, team only
$500 USD: secondary prize, individual only
$1500 USD: HTML5 game prize (Mozilla's contribution)

Requirements:

Everything must use GPL v3 and run under open license software. The idea is that everything compiles/runs on the Linux platform, and helps the open software initiative. They want the art to match their style guide, and I'm assuming they are looking for RPG style games. But the biggest goal is to push coders and artists to release GPL products. Mozilla is sponsoring the HTML5 portion, so I'm assuming any HTML5 games that win will get coverage from Mozilla's site. Also, this means that games made in Unity, AS3/Flex, Game Maker, etc. will not be accepted unless you can provide open-source libraries of the compilers.

I am interested in joining this for the coding stage! Not sure I want to commit a whole month (unless I work on/off), but I think I'm going to give it a go anyway Smiley

GPL v3 seems a bit much for graphical tile sets.  Either you retain ownership of your art or you put it out into the public domain.  What kind of restrictions does this put on game makers that want to use my tile set after the contest is over?  Must they include a raw copy of my art in every free or non-free game they make?

I'm not sure if I understand correctly; Do you have to make your own art for the first competition, and use that for the second programming competition?
What if you only want to enter the second competition, can you use art provided by the first competition from other teams?

Would be cool if you guys could also provice a list of programming languages that will be allowed, I'm having a hard time thinking of one.

From the rules:
License: Your art must be available under the CC-BY-SA 3.0 License and the GNU GPL 3.0.  You may license your art under any additional license(s) that you choose.
You can also license your work under a more permissive license in addition to GPL and CC-BY-SA if you want to, so you can make it more free, just not less free.

I'm not sure if I understand correctly; Do you have to make your own art for the first competition, and use that for the second programming competition?

Yes, that's the entire point; you use random art you steal from the first competition for use in the second competition. That's the entire point of free licenses; they allow people to steal your stuff and make new stuff with it.

As for the programming languages, I know that Java using OpenJDK is allowed. .NET using MONO, notably, is NOT allowed (or at least strongly discouraged, see the FAQ page). It would be nice if someone could compile a list of languages/libraries that could be used, yes.

Liberated Pixel Cup programming part starts tomorrow. I'll be joining unless something weird stops me (I had to drop out of 7DFPS because what I tried to do was not technically feasible for me and I didn't have the time to start over). Anybody else from here going to join?

This sounds really neat, I'm participating too with a chess like board game concept that I want to turn into pure epic.
As far as technologies go, I've decided to try out HTML 5 for this one and I'm currently trying to decide between LimeJS and EntityJS, but I more or less incline towards Lime right now.
