Use World Index, World Name and Game ID in Startup to configure Core Keeper.

Apply a Startup change

  1. Stop the server between sessions. For a save-related change, make a backup first.
  2. Open Startup → Variables, enter a value accepted by the field and wait for it to save.
  3. Start the server and check the result in game. If startup stops, read the first Console error before making another change.
Open Startup → Variables for the controls exposed by this server. This demonstration hides private values; file edits are made through Files.

Panel fieldPurpose and accepted values
World IndexSelects the Core Keeper world slot. Keep the current index when you intend to continue the same world.
World NameNames the Core Keeper world. World Index selects the save slot; changing this name is not a way to select a different saved world. Up to 100 characters.
Game IDCore Keeper’s connection identifier. Keep the existing valid ID to avoid changing the code your group uses; an empty or invalid value causes the game to generate another one.
