is there a way to make a trading system in blender? Because I am making a game (Bikers World) and I need to know if its possible. (the trading would be items and stuff)
Trading system? … trade with whom… over the net & stuff you mean?
-Edit-
So… 
I read your post for your game. Lot’s of movement down there… And yes, it would definetively be possible to do so. Haven’t you read the posts about online gaming here at the forum…
Trading would be so simple because it just requires to evaluate simple vars ONCE (not like checking the position of a player, etc…)
It all depends now on how you’re doing your INVENTORY system, etc… (Or maybe I’m just talking rubbish… who knows!?)
