12w18a is the fourth snapshot for Java Edition 1.3.1, released on May 3, 2012.[1]
This is the first version that makes singleplayer worlds run on a local server, resulting in the use of separate threads for rendering logic and world logic. This change resulted in a large number of broken features, several of which are yet to be fixed in the latest version, and on weak computers can result in server-lag in singleplayer.
Additions
Blocks
Wood, planks, and stone bricks
- Now have their proper names (e.g. "Oak Wood", "Spruce Wood Planks", "Mossy Stone Bricks").
Changes
Items
- Game no longer pauses when writing in a book and quill.
- Now obtainable from jungle tree leaves.
- Game no longer pauses when writing in a sign.
Wooden tools
- Can now smelt one item in a furnace.
Mobs
- When spawned from spawn eggs, they now get a random profession.
Gameplay
- The 1⁄4 second (5 tick) delay between block breaking has been removed for players in Survival. The player can now instantly mine a large amount of blocks in Survival simply by holding destroy if conditions are met.
- Hardcore is now available in multiplayer.
- Separated server logic and client, therefore singleplayer is now a local server.
Command format
General
- Game no longer pauses when entering a command or pausing the game.
General
- Coordinates are now rounded to 5 digits.
- "ws", "fs" and "g" (Walking speed, flying speed and ground; "g" is true if the player is touching the ground).
- Updated language files.
- Splash "Mojang" screen now appears for 1 second instead of 3.
- Support and auto-download for server texture packs.
- The server jar now accepts command-line arguments
--demo,--port,--singleplayer,--universe, and--world. The oldnoguiargument still works for backward compatibility.
Removals
General
Level previewer
- Removed the level previewer from the game's source code.
Features broken by the internal server
Main article: Java Edition 12w18a/List of broken features
- Many features were broken or significantly changed due to the client-server split, many of which still remain absent from the game.
- The particles from adding an eye of ender to an end portal frame block no longer appear offset if performed at high distances from the world origin.
- This is due to the fact that they simply did not appear at all from this snapshot onward, which is another bug entirely.
- This bug resurfaced in Java Edition 19w14a when the aforementioned absent particles bug was fixed.
Player
- The player "Notch" no longer drops an apple in addition to his inventory.
Fixes
4 bugs fixed
- Fixed being unable to switch tools of the same kind in inventory.
- Fixed water destroying non-solid blocks when breaking them from above.
- Fixed picking a block in Creative with a tool in hand causing the tool to be lost.
- Fixed Silk Touch yielding only one slab from double slabs.
Trivia
- In this version, when loading a singleplayer world, one needs to put
minecraft.zip/server/minecraft_server.jarinto.minecraft/servermanually to continue loading.
