Of course if you had access to the engine you'd just store each co-ordinate as a 32bit integer and use 29.3, which is about 536 million each axis, lol.You would still have the engine limits as to how large a particular room/area could be, i.e large == laggy. I wonder how this would impact on performance, especially memory use and how that would affect locality. A large map may cause a lot of page faults etc ... unless your a lucky boy with a Xeon :) then again if you started going in to the millions each direction I bet any computer will have a hard time :P Jeff. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
