Change World Seed

What is a World Seed?

A world seed is a number (or text that converts to a number) that Minecraft uses to generate the world. The same seed will always generate the same world layout, making it useful for:

• Creating specific world types
• Sharing interesting world layouts
• Recreating worlds
• Finding specific biomes or structures

Setting a Seed for a New World

Step 1: Access Server Properties

1. Log in to your panel
2. Navigate to your Minecraft server
3. Open the File Manager
4. Locate and open server.properties

Step 2: Set the Seed

1. Find the level-seed= line in server.properties
2. Enter your desired seed after the equals sign:

level-seed=123456789

Or use a text seed:

level-seed=MyAwesomeWorld

3. Save the file

Step 3: Create New World

If you want to use the seed for a completely new world:

1. Backup Current World: Save your current world if needed
2. Stop the server
3. Delete or rename the current world folder (usually world/)
4. Start the server
5. A new world will generate using your seed

Changing Seed for Existing World

Option 1: Create New World with New Seed

1. Stop the server
2. Backup your current world (rename the world/ folder)
3. Set the new seed in server.properties
4. Delete or rename the current world/ folder
5. Start the server (new world generates)
6. Your old world is preserved as a backup

Option 2: Use Different World Name

1. Stop the server
2. Set the new seed in server.properties
3. Change level-name= to a new world name:

level-name=world2
level-seed=NewSeed123

4. Start the server
5. A new world generates in the world2/ folder
6. Your original world remains untouched

Finding Your Current Seed

Method 1: In-Game Command

1. Connect to your server
2. Use the command: /seed
3. The seed will be displayed (if you have permission)

Method 2: Check Server Properties

1. Open server.properties
2. Look for level-seed=
3. If blank, the world was generated with a random seed

Method 3: Check World Files

1. Navigate to your world folder
2. Open level.dat using an NBT editor
3. The seed is stored in the level data

Using Popular Seeds

Many players share interesting seeds. To use one:

1. Get the seed number or text
2. Set it in server.properties as level-seed=<seed>
3. Create a new world (or change world name)
4. Start the server

Note: Seeds work the same across Java Edition versions, but may differ between major version updates.

Seed Examples

Random Seed

Leave blank for a random world:

level-seed=

Numeric Seed

level-seed=8675309

Text Seed

level-seed=MyServer2024

Multi-World Servers

If you're using a multi-world plugin:

1. Each world can have its own seed
2. Configure seeds in the multi-world plugin configuration
3. Seeds are set when worlds are created
4. Check plugin documentation for seed settings

Troubleshooting

Seed Not Working

1. Verify Format: Ensure no extra spaces or characters
2. Check World: Seed only affects new world generation
3. Restart Server: Changes require a server restart
4. New World: You may need to create a new world

World Not Generating

1. Check Permissions: Ensure server can create folders
2. Verify Disk Space: Ensure enough space for world generation
3. Check Logs: Look for generation errors in console
4. Try Different Seed: Test with a simple numeric seed

Seed Generates Different World

• Seeds may vary between Minecraft versions
• Major version updates can change generation
• Ensure you're using the same Minecraft version as the seed was created for
• Some seeds may not work in older/newer versions

Best Practices

• Backup Before Changes: Always backup before creating new worlds
• Document Seeds: Keep track of seeds you use
• Test Seeds: Test seeds on a local server first
• Version Compatibility: Be aware of version differences
• Player Communication: Let players know about world changes
