Preparing Your Server

Preparing the World Save File

Before launching the server, you need a valid world save file. Use the Sunkenland game client to generate a world, then transfer it to your server machine. For Windows users, save files are located in C:\Users\Your_User_Name\AppData\LocalLow\Vector3 Studio\Sunkenland.

Configuring the Server Script

Edit the start_headless_server.bat script in the server installation folder. Make a copy of the original script to preserve your changes through updates. The script includes parameters such as -nographics and -batchmode, which must remain unchanged.

Optional Configurations

Administrator Steam ID

Create a AdminSteamIDs.txt file within your world save folder and list the Steam IDs of users with administrator privileges.

Banned Steam IDs

Similarly, create a BanSteamIDs.txt file to list the Steam IDs of banned users, preventing them from accessing the server.

Server Configuration Parameters

Configure your server by editing the start script with the following parameters:

  • -worldGuid: The unique identifier for your world save file.
  • -password: (Optional) Set a custom server password, up to 8 ASCII characters.
