Non-mob entities

Minecart with TNT

• Triggered by activator rails
• Crafting recipe is a TNT block on top of a minecart (allowing for creation in the 2x2 inventory)
• When it derails, it explodes instantly, ignoring the usual timer delay
• Explodes even more violently the faster it goes
• In Creative mode when left clicked while moving, the Minecart with TNT explodes

Gameplay

Death messages

• Now includes the cause of death, the player the deceased player was fighting at time of death, and the name of the item used to kill.
• For death messages for fall damage, a complicated system was introduced.
  • There are now two types of messages, "[player] <first>" and "[player] <first> and <last>".
    • <first> can be:
      • fell [off a ladder/off some vines/out of the water/fell from a high place]
      • was [shot/pummeled/blown/fireballed/knocked] [off a ladder/off some vines/out of the water/from a high place]
      • was [shot/pummeled/blown/fireballed/knocked] [off a ladder/off some vines/out of the water/from a high place] by [player/mob]
    • <last> can be:
      • into a pool of lava
      • fell out of the world
      • into a patch of fire
      • into a patch of cacti
      • got finished off by [player/mob]
      • got finished off by [player/mob] using [item]
      • got finished off using [item]
  • There are 352 different death messages for falling. (Technically there are 416 because the verb "blown" exists twice in the en_US.lang file.)

Changes

Blocks

Anvils

• Improved naming of containers
  • Renamed Chests, Trapped Chests, Dispensers, Furnaces, Brewing Stands, and Enchantment Tables will display the new name in their GUI where the normal name used to appear.

Hoppers

• Is now controllable by redstone – Power it to disable item forwarding.
• Added a proper icon.
• Is no longer considered wooden (cannot be used as a fuel in a furnace, etc.).
• New crafting recipe uses iron ingots rather than stone.
• The redstone signal emitted when a redstone comparator is placed against it directly has changed.
  • 1 item will give a signal strength of 1, a 1/3 of a stack (21 for items which stack to 64) gives a signal strength of 2.
  • The number of full stacks x 3 = Signal strength.
  • E.g. 2 stacks of an item/block will give a signal strength of 6, while 2 potions will also give a signal strength of 6 (because a potion occupies one stack).

Lava

• Changed textures.

Redstone Comparator

• Updated texture.
• When fed by containers, they will now start giving out a signal as soon as 1 item is in the container, allowing for empty container detection.

Slabs

• The final "seamless" stone slab (and, by extension, smooth stone) has been removed as a result of the addition of quartz slabs

Trapped chests

• Now in Decoration Blocks in creative mode inventory.

Mobs

General

• Improved naming of spawn eggs
  • Mobs spawned from renamed eggs have the name of the egg and the names will appear in the death message.
  • Mobs can now display their custom name as nametag using an NBT tag.

Skeletons

• Improved aiming.
• Now shoots from 15 blocks away, instead of 10
• Accuracy changes by difficulty

World generation

Mineshafts

• Changed the chests to Minecart with chest.

Gameplay

Language

• Updated language files.
  • Language files can now be updated via the background downloader (no need for a new Minecraft release).

Missing textures and models

• Changed the missing texture from to
• Is now present in the texture atlases stitched_terrain.png and stitched_items.png

Texture packs

• Textures now use one file per block/item, which are stitched together at runtime – Texture sizes don't need to be consistent.
• Any block and item can be animated by putting the frames underneath each other in the right .png – Use an optional .txt to specify frame order and duration.
• Special rules apply for water, lava, compass, and clock.
• Existing texture packs will "automagically" be converted.
• Vanilla textures will be used if texture files are missing.
