12w18a is the fourth snapshot released for Java Edition 1.3.1.
This snapshot is known for being the version to make 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 computeres can result in server-lag in singleplayer.
- Wood logs now have their proper names (e.g. Oak Wood).
- Wood planks now have their proper names (e.g. Spruce Wood Planks).
- Stone bricks now have their proper names (e.g. Mossy Stone Bricks).
- Game no longer pauses when writing in a book. Whether this applies to book and quills is unknown.
- Cocoa beans are now obtainable in jungle tree leaves.
- Game no longer pauses when writing in a sign.
- Wooden tools work in furnaces as one full furnace use.
- Villagers spawned from spawning eggs will get a random profession.
- 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.
- Game no longer pauses when entering a command or pausing the game.
- F3 Debug screen
- 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.
- Server jar
- The server jar now accepts command-line arguments
--world. The old
noguiargument still works for backwards compatibility.
- Features broken by the internal server
- 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 will 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 onwards, which is
- This bug resurfaced in Java Edition 19w14a when the aforementioned absent particles bug was fixed.
4 bugs fixed
- Fixed being unable to switch tools of the same kind in your inventory.
- Fixed water destroying non-solid blocks when breaking them from above.
- Fixed picking a block in creative with a tool in your hand causing you to lose it.
- Fixed Silk Touch giving you only one slab from double slabs.
- In this version, when loading a single player world, one needs to put "minecraft.zip/server/minecraft_server.jar" into ".minecraft/server" manually to continue loading.
