Draft:Fictional universe of Minecraft

The fictional world of the 2011 video game Minecraft consists of an infinite world generated as the game is launched and 2 separate dimensions.

Description

edit

Minecraft allows the user to create an infinite amount of isolated worlds. Each world uses procedural generation to allow for seemingly infinite horizontal world sizes. Geological and biological features are mostly borrowed from real life, though fictious entries are also present, especially in non-Overworld dimensions.

Size

edit

Minecraft's worlds are generated primarily using a procedural generation algorithm, with some pre-made structures placed throughout the landscape. This allows for seemingly infinite world sizes that can stretch millions of blocks horizontally across all dimensions.[note 1] Based on the fact that one Minecraft block has a length of one meter, this makes the Minecraft world larger than most planets.[1]

The world's depth is limited in comparison, with a maximum depth of only 384 blocks. Attempting to build past the maximum height results in the block placement not being registered, while the bottom of the world is covered in unbreakable bedrock blocks.

Geography and climate

edit

There are three dimensions the player can access, which each one featuring different terrain types and biomes.

Overworld

edit

The Overworld is an Earth-like dimension the player starts in. It is divided into various biomes, each with a specific climate, vegetation and animal life. During night time, various monsters, such as the Creeper, spawn and attack the player. There are a total of 65 biomes within the Overworld.[2][note 2]

The Nether in Minecraft, a hell-like dimension with lava and fire.

The Nether

edit

The Nether is a hell-like underworld accessed via a player-made obsidian portal.[4] It consists of infinitely-sprawling caves made out of a fictious mineral called Netherrack, with Glowstones growing on the ceiling and oceans of lava present on the bottom.[5]

The End

The End is an island located in a space like area. The End is home to the main boss of the game Ender Dragon. It is also home to Endermen, who are tall black figures with purple eyes.[6]

Geology

edit

Mineral composition is available in caves, with different ores available to mine. Bedrock is an unbreakable material generating on the very bottom of the Overworld. There is an infinite void under Bedrock which would kill the player.

Notes

edit
  1. Java Edition features a hard barrier at 30 million blocks. Bedrock Edition becomes progressively more unstable over long distances due to precision loss, with the player falling through the world at around 8.3 million blocks.
  2. Some of the biomes usually has its own animals.[3]
