Terraria can generate a new world automatically when the server starts with a new world file name. Use this when you want a fresh map, a different world size, or a different difficulty.
Generate a world with the config editor
- Open your Terraria server in the control panel.
- Click Configuration Files.
- Open serverconfig.txt with the configuration editor.
- Enable Auto Create.
- Set the world name to a new value that is not already being used by an existing world.
- Select the world size and difficulty you want.
- Save the file and restart the server.
Generate a world with the text editor
- Open serverconfig.txt with the text editor.
- Find the world file line.
- Change it to a new file name, for example:
world=world2.wld - Make sure auto-create is enabled if the new file does not already exist.
- Save the file and restart the server.
World difficulty notes
The world difficulty is set when the world is created. If you change difficulty after a world already exists, generate a new world file so Terraria creates it with the new setting.
If the server keeps loading the old world, check that the world file name has changed and that the saved configuration was applied before restarting.
