Java Edition Classic 0.0.12a/Development

A couple of development versions of 0.0.12a were developed between May 17 and May 19, 2009.

Additions

 * Server development started.
 * Added basic code such as handling basic client connections and message sending.

Trivia

 * The version number is still "0.0.11a".
 * There are no known gameplay differences between this version and 0.0.11a.
 * This version is available in the launcher, mislabelled as "c0.0.11a".
 * It was added to the launcher along with several other versions on August 6, 2013.

Water test (May 18, 2009)
Word of Notch post, YouTube video (reupload)
 * Additions
 * Bedrock
 * Unobtainable to the player.
 * Cannot be broken, placed against or otherwise selected.
 * Surrounds the map on all four sides two blocks below ocean level, and also the bottom of the world.
 * Water
 * It was originally opaque, rendered as a full block and on the same layer as all other blocks (meaning it had shadows).
 * The player can swim in it, but mobs move under it at full speed. Swimming underwater was fast at first, as seen in the video.
 * Spreads from the world border on world generation to fill any empty space next to it.
 * World border
 * An infinite ocean now surrounds the map, making it impossible to fall off the world.
 * Pressing F now cycles between four levels of render distance.
 * Pressing N generates a new level, but without a level generation screen. Human mobs also don't get reset on level reset.
 * Changes
 * New terrain generator
 * Terrain is more messy, with more bumps visible on the surface.
 * Terrain now generates in islands.
 * No blocks can generate on ocean level, the terrain is always one block above it.
 * Dirt with access to sunlight will not become grass block upon world generation if below ocean level.
 * The sapling texture has been changed

Trivia

 * Water was made transparent before the release of 0.0.12a. To do this, Notch had to make it render on a new layer, which is why it lost its shadows. Water would stay without shadows until the release of 0.0.14a_08.
 * The terrain generation files for this version can be found in the 0.0.13a jar provided in the launcher. When ported to 0.0.13a, it is possible to see how the terrain worked. There are variables to enable/disable the water spreading from the borders, the uniform dirt layer and blocks being able to generate on ocean level.

Lava test (May 19, 2009)



 * Lava
 * Translucent.
 * Added shortly before the full release of 0.0.12a, as the screenshot of it posted on Notch's blog is from May 19th, 2009.
 * Water
 * Is now translucent and no longer renders as a full block.
