Note: This version is not available in the launcher and is considered lost.
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[]
Blocks[]
- 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.
- 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]
- 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[]
- An infinite ocean now surrounds the map.
- The player can no longer pass the edge of the map.
- Water next to lava will not produce stone upon world generation.
Gameplay[]
- Pressing F cycles between four levels of render distance.[4]
- Pressing N generates a new level, with a new level generation screen.[4]
- Only applies to players. Humans move at full speed in the water. Was originally much slower than in later Classic versions.
Changes[]
Mobs[]
- 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[]
- 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 block 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[]
- 1 bug reported
- The block being used to build does not show up unless it is a sapling.[9]
Trivia[]
- 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[]
- ↑ 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).
