Not to forget the clouds. (Btw with low resolution the clouds-shadow look ugly.)
Cool suggestion: Eatable MOUSE-pointers. Have you used the Advanced Search today? Need help, question? FAQ -Wiki -Forum help I still like small signatures...
Well, from source it should be three doubles, game.windspeed, game.windorientation, and game.windorientationchange. I can't tell that it does much more than move the clouds a bit right now...or where windspeed might change but, that should allow the creation of a wind turbine, with some extra coding (and maybe a bit of testing). Wind orientation seems to between 0 and 1, and windorientationchange is simply added to the orientation (every tick?) with a random chance (randomGenerator() < 0.001, whatever that chance may be) of being inverted (starts at 0.0001 and don't see it changing anywhere else)
Short: so currently (from what I can see) the wind speed never changes, wind orientation changes from 0-1 based on the addition of windorientationchange which starts at 0.0001 and can be randomly multiplied by -1 to reduce the orientation instead of increasing it.
off topic..hm you can also write to game.tick (of course there is a comment: // to be used with care, lol)
