    Hello Everyone,

    I want to make a connection approval process that can reject incoming connections based on any number of connected players. How can I limit the number of players (Clients) connecting the game (Server)? Does network driver count the connected players or should I do my own counter on server side? How can I use ServerClientCount in Bootstrap (ClientServerBootstrap.WorldCounts.Data.serverWorlds
    Code (CSharp):
    1. ClientServerBootstrap.WorldCounts.Data.serverWorlds
    )

    Code (CSharp):
    1. public static void RegisterServerDriver(World world, ref NetworkDriverStore driverStore, NetDebug netDebug, ref FixedString4096Bytes certificate, ref FixedString4096Bytes privateKey, int playerCount = 0
    2.         {
    3.             var settings = GetNetworkServerSettings(playerCount: playerCount);
    4.             settings = settings.WithSecureServerParameters(certificate: ref certificate, privateKey: ref privateKey);
    5.             RegisterServerDriver(world, ref driverStore, netDebug, settings);
    6.         }
    Thanks in advance.

    Hey OrientedPain!

    Unfortunately there is currently no way to limit player count via UTP directly. You'll need to:
    1. Accept the connection.
    2. Immediately close it again (via the NetworkConnection entity) based on connected player count. Optionally after sending an RPC containing a reason for the server kick.
    Relatedly, you may find the following thread valuable, depending on the kind of security you need for your game:
