Oh I think I god it !
If you change the Global Constant variable text with something no one has only the player of your app will be able to join your server and no one else ? So I can totally use the Official server of scirra to play because no one could come to my application server !
Am I right ?
Normally, the forums are pretty active,but if someone doesn't really understand what you're trying to say, then they won't bother to reply.
Yes, you will have to change the Constant variable to your own game name for someone to join your private game room on the official Scirra signalling server.
