[Enigma-devel] iOS revisited

[Carsten Pedersen]

So first of all I'm new to this list and have only done a quick browse through 
the archives where I did find an old thread mentioning the possibilities of on 
iPhone port. Lot's of discussion about possible licensing issues but no real 
conclusions. I'm a long time Mac and not so long time iOS developer and one of 
the first things I thought of when the iPad came out is that an Oxyd type game 
would be great for that platform. So I did some Googling and was happy to 
discover that the Enigma project made an Oxyd like experience possible under OS 
X. I would love to do an iOS implementation and I'd prefer doing it without 
using any of the Enigma source, mostly because utilizing the native Core 
Animation frameworks would be more efficient and result in much less code.

Writing a native game engine is one thing, level design is potentially much 
more work and obviously I'd like to take advantage of all the levels that have 
been created for Enigma. So my question is first of all what would this mean in 
regards to licensing? If I develop my own game engine (without even looking at 
the Enigma game engine source) and include Enigma levels will that still force 
my application to be GPL V2? Also even if complying with rules for the Enigma 
project could there still be dodgy legal issues relating to usage of the 
recreations of original Oxyd levels?  One variant could be to ship the game 
with a small set of self designed levels and somehow allow upload of Enigma 
compatible XML level files.

It is unclear to me under which conditions user defined levels are submitted 
and also the exact origins of the currently enclosed level packs.

I realize that my approach might be frowned upon for not contributing to the 
open source project as such but my motivation here is getting the game to run 
on iOS and at the same time building my own skills as a game developer on that 
platform. So yes go ahead and shoot me :)
