How do I lock room after i want to start game

hi ,

how do i lock the room after i want to start game ? my game dont have enough peer to lock when full but players wants to start and in my game after game start no one must can join into room...

and,

how do i get the same instance object in the other peer ?

if we have something like NUID this can be very useful like UID but same in all peers

When player wanna to join the game

ask host now player count frist

When player wanna to join the game

ask host now player count frist

what ?!

i dont understand that !

i just disconnect all peers then create a new room with a different instance and all peers connect to that so new players can not see the new room! but this create so much problem like : when a peer can not join host or if peer join sooner the real host and... !!

what i must do ?!

I wanted to know this. Like Little Big Planet. The point u walk across disables players from joining
