Minecraft Realms
  • Currently a preview
  • Subscription-based vanilla server rental service provided by Mojang
  • Server can't be modded, no ops can be appointed and a whitelist is mandatory
  • Only added to few "randomly" chosen players
  • Used on Menu Screen, when activated


Scoreboard system
  • Intended for map makers or server administrators.
  • Used via /scoreboard command or command block
  • Track, edit and display certain objectives per player, such as kill count or health (read-only)
  • Group players into teams to have the option to assign custom nametag colors, disable friendly fire and allow invisible teammates to be seen
  • /testfor
    • Tests for whether specified player is online (testfor [player]), or at specified coordinate and/or in radius (/testfor @p[x,y,z], testfor|@p[r=radius] or testfor|@p[x,y,z,r=radius])
    • Signal output to any redstone comparators surrounding the command block like testing content of a chest
  • /effect
    • Usage: /effect <player> <effect> [seconds] [amplifier]
    • To remove effects: /effect <player> <effect> 0
    • Maximum number of seconds is 1,000,000
    • Amplifier increases level of the chosen status effect
  • /scoreboard
    • Used to interact with the scoreboard system
NBT related
  • Minecarts can now carry any block and have any minecart function (TNT, hopper, chest, furnace, ridable)
  • FallingSand can now be a TileEntity
  • Named entities can display their nametag when in nametag range
  • Minecarts can now act as spawners
  • Entities can now permanently ride other entities
    • Can be achieved by using Sethbling's MCEdit filter (Stack Entities). Can be found here
    • No longer dismount upon reload
    • Allows for a lot of customization, including "riding" bats by spawning a bat with a minecart on top, spider jockeys etc.

World Generation[]

Nether quartz ore
  • Found in the Nether
  • Drops nether quartz crystal when mined
  • There is an average of roughly 70 ores per chunk
  • Works with both Fortune and Silk Touch enchantments

Blocks & Items[]

Activator rail
  • The crafting recipe is 2 sticks, 6 iron ingots and 1 redstone torch
  • Used to trigger minecart with TNT
  • Used to stop item passing on minecart with hopper
  • Needs to be powered by redstone
  • Transmits redstone signal to 8 Activator Rails far
Block of redstone
  • The crafting recipe is 9 redstone
  • Stores 9 redstone
  • Emits constant redstone signal = same as the Redstone Torch
  • Works as pushable redstone power source
Daylight sensor
  • The crafting recipe is 3 wooden slabs, 3 nether quartz and 3 glass blocks
  • Outputs a signal with a strength corresponding to the intensity of the sun
  • Only works with the sun's light (not man made light such as torches)
  • Rain affects the sensor's output
  • The crafting recipe is 7 cobblestone and 1 redstone
  • Places items in containers in front of them, if there is no container it will dispense the item without using it
  • A dispenser “shoots" items at you, while a dropper “throws" items at you[2]
  • Can face all 6 directions, with a different texture when facing up or down
  • Need redstone signal to drop items
  • Fires once when the input becomes powered
  • Redstone signal emitted when a redstone comparator is placed against it directly - signal length depends on its fullness
  • The crafting recipe is 5 iron ingots and 1 chest
  • Places and takes out items in hoppers, chests, furnaces, minecart with chests, minecart with hoppers, dispensers, droppers, and brewing stands
  • Allows for the automation of many processes collecting drops
  • Powering the hopper stops it from [taking] in items and releasing them
  • Redstone signal emitted when a redstone comparator is placed against it directly - signal length depends on its fullness
    • 1 item will give a signal strength of 1, a third of a stack (21 for items which stack to 64) gives a signal strength of 2
    • The number of full stacks × 3 = Signal strength
Minecart with hopper
  • Crafting recipe is a hopper on top of a minecart
  • Can only be emptied by passing over a hopper
  • Can pick up items from containers when it passes over
Minecart with spawner entity
  • Only obtainable with world editors
  • Have only the entity not the item
  • Uses the same NBT format as a normal spawner
Minecart with TNT
  • The crafting recipe is 1 TNT and 1 minecart
  • Triggered by activator rails
  • Explodes even more violently the faster it goes
  • Doesn't destroy rails and supporting blocks
  • Still blows up redstone materials
Redstone comparator
  • Based on the idea of the Capacitor mentioned at Minecon 2012
  • The crafting recipe is 3 redstone torches, 1 nether quartz and 3 stone
  • It is the same as a repeater, but with 2 inputs
    • If input A is stronger or equal to input B, it either repeats the signal or outputs the difference between A and B, so this can be used as an easier way make redstone contraptions like piston doors
      • Output is toggleable by right clicking
    • If input A is weaker than input B, then there is no output
  • All containers output a redstone signal when a redstone comparator is placed against it directly. The strength of it depends on how full the container is and what disc number is used in a jukebox
    • This works with trapped chests as well, meaning it can provide two redstone signals with different causes at the same time
Trapped chest
  • The crafting recipe is 1 chest, and 1 tripwire hook
  • Gives out a signal depending on the amount of players looking inside
  • Large trapped chests can be staggered with Large Chests to allow more compact storage
  • Transmit signal downward through one block. This does not apply horizontally[3]
  • Texture is slightly different than a normal chest, with a red stain around the latch
Weighted pressure plate
  • Used to detect item drops
  • Gold(light) version reaches full strength at 60 items
  • Iron(heavy) version reaches full strength at 600 items
  • Linear, so 10 strength signal means twice as many items as a 5 strength signal
Nether Brick (item)
  • Obtained by smelting netherrack
  • Used to make nether brick
Nether quartz
  • Picked up when you break or smelt nether quartz ore
  • Is a crafting ingredient for daylight sensors and redstone comparators
  • Can be crafted into decorative blocks
Nether quartz ore
  • Drops 1 nether quartz item when mined
  • Can be smelted in a furnace to obtain nether quartz
  • Can be legitimately obtained with Silk Touch enchantment
  • Drop more when mined with Fortune enchantment
Block of quartz
  • The crafting recipe is 4 nether quartz in a square
  • Decorative block
Quartz slab
  • The crafting recipe is 3 blocks of quartz
  • Can be placed upside down
  • Decorative block
Quartz stairs
  • The crafting recipe is 6 block of quartz in a usual stair recipe
  • Can be placed upside down
Chiseled Quartz Block
  • The crafting recipe is 2 quartz slabs
  • Decorative block
Pillar Quartz Block
  • The crafting recipe is 2 vertical block of quartz
  • Decorative block
  • Pillar quartz blocks can be placed sideways, using the side of the block to place similar to sideways wood
Multiple snow heights
  • Fully implemented - previously, a world editor could be used for different heights of snow
  • Drops one snowball for every layer of snow
  • Each level of snow has its own height collision
    • The topmost layer of snow does not have collision, so the player is always slightly sunken in the snow
    • Visually, four layers of snow is the same height as a slab. However, five layers of snow has the same collision height as a slab
  • Crafting recipe is 3 snow blocks in a row to create 6 snow layers
    • For each thin layer of snow crafted, the player loses exactly half the snowballs required to produce it
Sandstone double slab
  • The block ID is 43:9



  • Engine optimizations
  • Support for more realistic lighting[4][5]
  • Lighting interacts correctly with slabs and stairs[6]
  • Note: Active furnaces still emit light only from the front surface (as before), and black spots have not been fixed
Texture packs
  • Textures now use one file per block/item, which are stitched together at runtime
  • Each texture can have its own resolution and may be animated by putting the frames underneath each other - A text file is needed to specify frame order and duration
  • Special rules apply for water & lava (double size) and compass & clock (non-animatable, frames are used for moving parts)
  • Vanilla textures will be used for missing texture files
  • Fonts are changeable as well, even to HD fonts
  • Support for HD texture packs.[7]
Server list
  • The Direct Connect IP is now saved even after closing the game
  • Fortune now affects apples and potatoes.
