A seed or world seed is a combination of letters and numbers used to specify how terrain is generated when creating a new world in Minecraft.
Since a seed is the basis for how a world is generated, using the same seed will generate the same terrain. You can use the command /seed to display your current world seed. Do note that this may not work for servers that you do not have permission to use such command.
# Note When Using Custom Seeds
- Generated worlds using the same seed on different versions of Minecraft may not be identical especially with versions that feature new biomes or a different world generation just like Minecraft 1.13 (Update Aquatic).
- World seeds are a feature on all editions/platforms for Minecraft (Java, Bedrock/MCPE, etc.). However, a seed can only be used on the same platform it was from. When used on a different platform or edition of Minecraft, the terrain will not be identical. A seed for a Minecraft Java Edition world will not yield the same one when used in Minecraft Bedrock/Pocket Edition.
- Seeds can be used in both single-player and multiplayer (servers).
Using a custom seed allows you to customize the generation of your world. You can get a seed from a friend or you get a seed online from forums like MinecraftForum.net and other websites for sharing world seeds.
# How to Use a Custom Seed on Your Server
You can easily use a custom seed for your server's world generation by simply changing an option in your server settings file.
- Access your control panel and Shut Down your server.
- Navigate to the Files Tab
- Open up
server.properties - Locate the Level Seed option and enter the seed you would like to use.
- Save your changes at the bottom of the page and start your server.
If you have an existing world, you will need to reset/delete this before starting your server (How to Reset your Minecraft World) in order for a new world to be generated using your custom seed.
After that, that's it! You have successfully used a custom seed for your server's world generation.
