It's pretty sad when you go to take some "me" time away from development to just mess around and develop again but in a different game engine (this is what I choose to do for fun I don't know what else to do I hate sports.)
When you work for yourself, you expect more so you end up dead beat anyway by the end of the day. For anyone who's interested here's a link to my blog if you want to check out my first commercial game.
So ghosts can go through walls and stuff, and depending their type (according to fantasy media) they can or can't interact with objects to a certain degree...
So why they don't always fall through floors? Do they always float and sometimes simulate walking? If things go through them how can they hear/see? And why sometimes they have clothing? Do clothes die as well?
