World Types

Type Description Image
Default This is the default type of generation. Various landscapes generate utilizing Biomes. File:Minecraft 2.jpg
Superflat This type of generation creates a world that is completely flat. It has an altitude of 4, but has no Void Fog. The first layer is composed of Bedrock, with two layers of Dirt on top of it, and topped off with a layer of Grass. Mobs spawn normally, with a large amount of them being Slimes. As no trees or ores exist, this World Type is primarily used for Creative Mode. Generate Structures allows Villages to generate, which can provide resources for Survival Mode. It is based on the flat map type of the Indev version.As of 12w37a, custom Superflat worlds can be created, and as of 12w40a,Superflat customization allows you to spawn trees, strongholds,etc. Also, blocks like pumpkins and ores can spawn in Superflat worlds. Flatland
Large Biomes Generates a Default world type, but with each geographic feature taking up 4 times as many blocks per axis, which results in larger biomes (16 times as much area). Large Biome

Trivia

Default

  • This was the only available world type until the release of Minecraft 1.1, adding Superflat worlds.
  • The first World Type.

Superflat

  • In Superflat World type, the Void appears sky color from above Y coordinate 0. However, when viewed from below this coordinate, the Void appears its normal black color.
  • Slimes are very common on Superflat worlds, as the ground level is only 4 blocks above the bottom and slimes spawn from layers 40 to the bottom.
  • Villages spawn rates are somewhat increased when using this world type.
  • In Superflat the Nether and the End generate normally.
  • Starting in version 1.4, it is possible to customize what block layers Superflat worlds are made of.

Large Biomes

  • The world is generated like normal, only biomes are 4 times bigger linearly (16 times by area).
  • When comparing a normal and Large Biomes worlds with the same seeds using a map, the Large Biomes world looks like a zoomed in version of the Normal world.
  • Rivers are not larger than they are in Default.
