Connecting to a Dedicated Server

Overview​

This guide outlines methods to connect to a dedicated server in Unreal Engine, depending on your DefaultEngine.ini configuration. The connection is facilitated using the Execute Console Command node in Unreal Engine. Three distinct methods are detailed below: SteamCore PRO Sessions, SteamCoreSockets, and IpNetDriver.

Method 1: Using SteamCore PRO Sessions​

This method leverages the SteamCoreSockets NetDriver for connecting to a dedicated server.

  • Configuration: Refer to the SteamCoreSockets Configuration Guide.
  • Steps:
    1. Use the Find SteamCore PRO Sessions node to discover available multiplayer servers.
    2. Connect to a server using the Join Session node.
Important Note

The provided example automatically joins the first session found and is intended for demonstration purposes only. For production environments, implement a comprehensive server list UI. Refer to the Blueprint example project for guidance.

Method 2: Using SteamCoreSockets (Bypassing Online Subsystem)​

This method uses SteamCoreSockets to connect directly to a server without relying on the Online Subsystem.

  • Configuration: See the SteamCoreSockets Configuration Guide.
  • Console Command: 
    open steam.P2PAddr:Port
    • Replace P2PAddr with the server’s Steam address.
    • Replace Port with the appropriate port number.
note

This example demonstrates connecting to the first available server. For production, implement a proper session browser to allow users to select from available servers.

Method 3: Using IpNetDriver (Bypassing Online Subsystem)​

This method is used when not relying on Steam or any other Online Subsystem, utilizing the IpNetDriver.

  • Configuration: Refer to the IpNetDriver Setup Guide.
  • Console Command: 
    open <IP>:<Port>
    • Replace <IP> with the server’s IP address.
    • Replace <Port> with the appropriate port number.

Best Practices​

  • Always implement a server browser for production to allow users to select from available servers rather than auto-joining the first session.
  • Ensure proper configuration in DefaultEngine.ini to align with your chosen connection method.
  • Test thoroughly to confirm compatibility with your networking setup.
