Differences Between Seeds and Terrain Generators
Note: This is more of an informational section and is not required for you
to change your seed, but it can be important to know the differences
between the seed and the terrain generator and why they get mixed up
Seeds and terrain generators are often confused by people, which is understandable as they are related to each other. The biggest difference is the purpose of each of them.
- Terrain generators create the overall features of the world as it is being explored
- Seeds tell the generator what randomness to create the world with
- If two players generate two worlds with the same seed, and the same terrain generator, they will get exactly the same world
- If two players generate two worlds with the same seed and different terrain generators, they will get very different worlds
- If two players generate two worlds with different seeds and the same terrain generator, the worlds will be different to each other

do not start the server yet. Go into the
Server Configurationtab from the menu on the left.
Scroll until you find the
Level Seedmenu. Input the seed that you want to use in the box, this can be anything, it will be converted to a number if you input a word, but it will still be the same seed.
When you input a word as a seed, Minecraft will turn it to a number, but it will still be the same seed.
