Licencing question....

[Mistajase]

Hi there, I'm working on my own mobile game at the moment.... haven't even given it a title yet, it's still early in development.
its a kind of top down tile based 'resource management/god type' at the moment I have the tile engine working but now I'm gathering the graphical elements I need (I'm a developer not a designer) so everything Im using so far are from 'royalty free' sources which I can use (credit given).
If I ever finish this project I would like to put it on app/play store.

Anyway so my question is that, I've found a few animal spritesheets on this site and the wiki which are perfect and I wondered if I can use them ( credit given to the authors of course ).
i expect i'd would I have to ask for the authors permission first?
What are the rules on this?

Also If any artist out there has any animal spritesheets that you would allow me to use plz reply!

Art License is in the git repo -> https://github.com/themanaworld/tmwa-cl ... icense.txt
Otherwise its all GPLv2 (unless otherwise stated on page or via the author.)

Thanks for the reply.... All the licencing malarkey can be such a bore, but unfortunately nesesary.

The gplv2 licence confuses me though. If I use a spritesheet on a paid for app but give the source file away free under the same licence (with credit to the original author), then thats legally okay?

Thanks in advance!
People on the forum seem to be quite knowledgeable on licencing issues!

[wushin]

No, combining the 2 into a single program would violate the GPLv2 if you mixed them like that http://www.gnu.org/licenses/old-license ... tarySystem

Thanks again Wushin!

Another thing that was confused me is that some spritesheets have the GPLv2 and CC BY-SA 3.0 licence - but they seem to contradict each other...

It was my understanding that anything under the CC BY-SA 3.0 licence allows commercial usage?

Thanks in advance!

This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. All new works based on yours will carry the same license, so any derivatives will also allow commercial use.

With that said We use all our art as GPLv2. As We recently started to ask the artists to dual it for cc-by-sa-3. We are really not a 100% on whether all the accreditation is complete to satisfy cc-by-sa-3, so that is still use at your own risk.

Thanks for the info wushin - I'm trying to play safe with all the legal technicalities.

I appreciate + respect you taking the time to explain everything!
