For more information on the server address and port required to connect to the in-game server, please refer to the documentation on information for connection to the in-game server.


Attempts to connect to the in-game server.

  • The fact that the in-game server connection method returns true means the server is connected to the socket; it does not mean that the server connection was successful.
  • Actual server connection is established after user authentication is completed in the in-game server, and the success/failure of connection to the in-game server can be checked via the OnSessionJoinInServer event.


string serverAddress;
ushort serverPort;

OnMatchMakingResponse += (args) => // Place to check serverAddress and serverPort
string serverAddress = args.RoomInfo.m_inGameServerEndPoint.m_address;
ushort serverPort = args.RoomInfo.m_inGameServerEndPoint.m_port;

void JoinInGameServer() // Random method
bool isReconnect = true;
ErrorInfo errorInfo = null;

if(Backend.Match.JoinGameServer(serverAddress, serverPort, isReconnect, out errorInfo) == false)
// Error confirmation
