A Minecraft seed determines how the terrain, biomes, structures, and other world features are generated. Changing the seed does not modify a world that already exists. The new value is only used when Minecraft creates a new world.

​
Configure the World Seed

  1. Log in to the game panel at gamepanel.fourseasonshosting.com.
  2. Open your server and stop it from the Console page.
  3. Go to Files and open server.properties.
  4. Locate the following setting:
  5. Enter the seed you want after the = sign. To have Minecraft generate a random seed, leave the value blank.
  6. Save the file.
If you cannot find level-seed in server.properties, start the server once and allow it to finish generating its configuration files. Stop the server afterward and edit the file.

​
Generate a New World

After setting the seed, you need to make Minecraft create a new world. There are two ways to do this.

​
Option 1: Remove the Existing World

If you no longer need the current world:
  1. Open Files.
  2. Locate the world directory currently being used by the server.
  3. The folder name normally matches the level-name value in server.properties, which is commonly world.
  4. Delete the world folder.
Deleted files are moved to the Trash, so you may be able to restore the world if you change your mind.
Before deleting the world: Create a backup if there is anything in the existing world that you may want to recover later.

​
Option 2: Keep the Existing World

If you want to keep your current world while generating another one:
  1. Open server.properties.
  2. Find:
  3. Change the value to a new world name, such as:
  4. Save the file.
Because a world with the new name does not exist, Minecraft will generate one when the server starts.

​
Start the Server

Start the server from the Console page. Minecraft will generate the new world using the seed configured in level-seed. Your previous world remains available if you used the second method.
