question, as it looks all great, how does a game handle with a huuuuge level, would it update every position of players around, or just players that are nearby ?

I've been strangled with this too while i was making an MMO in Flash..
though how i solved it, i parted everything up in areas, which then are stored in a variable, and only loads the stats of people in the same area, maybe you could do this the same with an invisible block, and use c_content ?

just a suggestion, offcourse this would involve a lot of them setups, but if it speeds up the game

regards,
