link appears to be broken?
Buildings:
bUnhappyProduction
- assumed it is: add one base production per unhappy citizen
iSprawling
- realize not implemented yet so probably a mute question: modifies workable city tile radius?(could it be negative?)
ta mate =)
now I just have to figure out how to make it land type terrain -_-
Depends on what your trying to accomplish. Ice is a feature (ie forests, sits on top of terrain), so you'll likely have to change the under lying terrain via script/event to snow and remove the ice.
Sounds like someone is trying to make an option to get rid of Unique Features for multiplayer
Wish I could help, but what I know about coding (and the FfH code) could be written on the back of a stamp.
addGameElements calls addImprovements and addUniqueImprovements after goody huts are placed. They are all in CvMapGenerator.cpp.
