# NetworkRoomManager

\*\*Please see the Room example in the Examples folder in your Mirror folder

The Network Room Manager is a specialized type of [Network Manager](NetworkManager.md) 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
-   Option to prevent players from joining a game in progress
-   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](NetworkRoomPlayer.md) component

**Player Prefab**
-   One for each player
-   Created when game scene is started
-   Destroyed when leaving game scene
-   Handles commands in the game
