0.0.12a[1] was a version of Classic released on May 19, 2009, at 22:36 UTC.[2][note 1] It added bedrock, water and lava, along with a world boundary and a new world generator.

Additions[edit]

Blocks[edit]

Bedrock JE1 BE1.png Bedrock
  • Unobtainable to the player.
  • Initially referred to as "unbreakable stone."
  • Bedrock and the layer above (if at the bottom of the world) is always dark even if exposed to the sky.
  • Cannot be broken, placed against, or otherwise selected.
Water JE1.png Water
  • A type of liquid.
  • Does not drown the player.
  • Is transparent.
  • Spreads Infinitely.
  • Water does not work outside the map (it won't spread from world border after terrain generation).[3]
Lava JE1.png Lava
  • A type of liquid.
  • Originally was transparent, just like water.
  • Underneath lava, the mist is thin and orange in color.
  • Does not deal damage to the player.
  • Spreads Infinitely.

World generation[edit]

World boundary
  • An infinite ocean now surrounds the map.
  • The player can no longer pass the edge of the map.

Gameplay[edit]

Controls
  • Pressing F cycles between four levels of render distance.[4]
  • Pressing N generates a new level, with a new level generation screen.[4]
Swimming
  • Only applies to players. Humans move at full speed in the water. Was originally much slower than in later Classic versions.

Changes[edit]

Mobs[edit]

Steve Revision 1.png Humans
  • No longer get reset on level reset, meaning there is no way to get rid of mobs now.[5]
Physics
  • Water and lava now flow to fill any available space below or next to it.[6]
    • With just one water source the entire world will be flooded.[7]
  • Water next to lava produces stone.
  • Player jump height increased by about 0.5 blocks.[8]

World generation[edit]

New level generator
  • Terrain is messier with more bumps visible on the surface. It also now generates in islands.
  • The terrain always generates one block above ocean level.
  • Lakes occur when the surrounding water is at a higher level than the terrain.
  • All dirt with access to sunlight will not become grass upon world generation if below water level.
  • Lava lakes also spawn occasionally.
  • Worlds made before this version will receive a bedrock layer at the bottom of the map and an ocean surrounding it

Bugs[edit]

  • The block being used to build does not show up unless it is a sapling.[9]

Trivia[edit]

  • The video released by Notch on May 18th showing off 0.0.12a is actually a developer variant that was never released to the public. See Development for more information on this.
  • To make the water and lava texture display slightly shorter than a block, it's texture from terrain.png gets shifted down a bit in-game. This causes the texture to overlap with the block below at some angles.
  • The 0.0.13a-launcher jar contains the level generation files for this same version, which is also the same terrain generation files used in the full, public release of it (and 0.0.12a_01-03). It has variables that can enable and disable the uniform dirt layer, and it has been disabled for the public variant of 0.0.12a (or at least 0.0.12a_03 for certain). It also has variables for the water filling up the world from the corners, which can be disabled.

Notes[edit]

  1. While some sources imply that this version was released on May 20, due to timezones differences it was actually released at 22:36 UTC on May 19 (which is 00:36 on May 20, Sweden time).
