To create a game...

[Debci]

My intention is create a derivated game using the code of planeshift, can i do this? i cant use the art and multimedia orginal content of the planeshift, but i can use the code for develop an game?
I readed the license but I was not too clear.

You can re-use the code, if you publish your game code as well under the same license, the GPL.
For more info on the GPL look here: http://www.gnu.org/licenses/gpl.html

You can of course keep your game content, the maps, sounds, settings etc. proprietary just as Atomic Blue do with PlaneShift. But pretty much you are correct, you can make a game with the PS code.

It's a long read, but many of these links may be useful to you.

If you want to start somewhere, I'd suggest the compiling guide.

Also, take a look at The Planeshift Engine wiki.

To answer your exact question:

Art is under closed license. (ABC license)
Quests, game rules are under closed license. (ABC license)
The code is free to use (GPL license) but you must make the sources public if you create derivative code.

To create a new game, you have to create your own art (models, textures, music) as well as database content (game rules, quests, descriptions etc).

The code is free to use (GPL license) but you must make the sources public if you create derivative code.

That's only true if you distribute your derivatives; you can mod the server as much as you want without distributing the code to it as long as you don't distribute the server.

note that quest and game rules in svn repositories are gpl the real rules aren't there

ok, i can use the db on the svn to develop? it is gpl?

[weltall]

yes although probably you will need to remove all the race definitions and change them properly (and references to meshes/textures available only on the ABC art)

ok, thanks ^^
