Network Room Manager

Please see the Room example in the Examples folder in your Mirror folder.
The Network Room Manager is a specialized type of Network Manager that provides a multiplayer room before entering the main play scene of the game. It allows you to set up a network with:
  • A maximum player limit
  • Automatic start when all players are ready
  • Game is locked after start, preventing late joiners
  • Customizable ways for players to choose options while in room
There are two types of player objects with the Network Room Manager:
Room Player Prefab
  • One for each player
  • Created when client connects, or player is added
  • Persists until client disconnects
  • Holds ready flag and configuration data
  • Handles commands in the room
  • Must use the Network Room Player component
Player Prefab
  • One for each player
  • Created when game scene is started
  • Destroyed when leaving game scene
  • Handles commands in the game


  • Show Room GUI Show the default OnGUI controls for the room.
  • Min Players Minimum number of players needed to start a game.
  • Room Player Prefab The prefab to create for players when they enter the room (requires Network Room Player component).
  • Room Scene The scene to use for the room.
  • Gameplay Scene The scene to use for main game play.
  • pendingPlayers List that holds players that are ready to start playing.
  • roomSlots List that manages the slots for connected clients in the room.
  • allPlayersReady Bool indicating if all players are ready to start playing. This value changes as players invoke CmdChangeReadyState indicating true or false, and will be set false when a new client connects.
