Every time you create a new world in minecraft, it will be assigned a random unique value, known as a seed. This seed is kind of like a barcode for minecraft saves, and allows minecraft players to share the cool worlds that they have found with other people. However, any changes made to the world made by the player will not show in a newly created seed.
You will not always spawn in the same location for every seed, sometimes you will spawn in random places of the same world. When a new major patch comes out for minecraft, each seed is usually changed in some way, and so a seed made in version 1.1 of minecraft, may not be the same as in version 1.2.
- The seed ID is case sensitive, so always make sure to copy it exactly.
- To find out the ID of a seed while in-game, type /seed in the chat bar and press enter.
- When creating a new seed, remember to make sure that “Generate Structures” is on, otherwise villages, temples, dungeons and ocean monuments won’t spawn on the map.
- Desert Temples, Jungle Temples, and Desert Villages will only spawn in minecraft version 1.2 and above.
- Ocean Monuments will only spawn in Minecraft version 1.8 and above.
- Minecraft version 1.3 to 1.5 will likely always have the same seeds.
To create a custom seed in minecraft, enter the singleplayer world selection at the main menu of the game, then press the “Create New World” option.
On this screen, press the “More World Options…” button and there you will be able to enter your custom minecraft seed for the world.
