the Logics…

When The player input his name and click on Create he will go to the create scene and w8 for players and his name will be displayed in the first bar at the top most…

When he clicked on join he will go to the join scene where he is required to input the ip address of the server or host… upon inserting the ip address and clicked on join he will be connected to the server and see the servers interface… but he is not able to click in create( where the game is going to start)…
