HI,
indeed, this demo is only your way out of learning how Photon is integrated in PLaymaker. It is important that you gain knowledge of this before moving on into doing your own stuff.
In this case, it's only a matter of presentation and UI. In this demo, the ui was done in testing mode kind of way, where obviously for a real game, the ui would offer something totally different, like for example, a set of hardcoded rooms, or a more robust way to create/join rooms, etc etc.
If you ask very granular questions on this forum, you are likely to get answers and progress this way. However if you need consultancy or developement work force to help you move faster on sensitive projects, do not hesitate to pm me, so that we can arrange something.
Let's wait for me to do this new demo variation, and then we'll see if that helps you progress in your game.
bye,
Jean
