Hi again, I’m trying to initialize a simulator in room that controls everything(players etc). I uploaded my simulator to cloud but when I enter the play mode in the editor there is no room in the UI list, if I create one then simulator initialize. How can I create a room with simulator automatically? My goal is when player join the room there should be already initialized simulator. Or am I missing something?

Thank you for your time.

Simulators only start when you create rooms, so a game client must create the room first, and then a simulator automatically starts and connects.
