Gameplay

Target selectors
- @e
  - Targets entities
  - Can specify type of entity by entity ID to either include or exclude with [type=Chicken] or [type=!Skeleton]
  - Example: /kill @e[r=50,type=Chicken] - kills all chickens within a radius of 50 blocks
  - Example: /tp @e[r=5] ~ ~5 ~ - any entity within a radius of 5 blocks will be teleported five blocks in the air
Commands
- /blockdata
  - Modifies NBT data at a specific coordinate. The <dataTag> merges with the block at that position
  - Can be used to change the contents of a chest
  - Usage: /blockdata <x> <y> <z> <dataTag>
- /clone
  - Clones all the blocks (not entities) from a given area to a different given area
  - Up to 4096 blocks can be copied
  - The clone can be masked or replace - replace will copy every block, masked will only copy non-air blocks
  - Usage: /clone <x1> <y1> <z1> <x2> <y2> <z2> <x> <y> <z> [mode]
  - Example: /clone 1001 3 1002 1011 3 992 1001 5 992 masked
- /execute
  - Allows commands to be run from the position of specified entities
  - Example: /execute @e[type=Chicken] ~ ~ ~ fill ~-1 ~-1 ~-1 ~1 ~1 ~1 minecraft:glass
  - Commands run using the execute command pass their success value back to the command block running them
- /fill
  - Fills a given volume with a specified block
  - Up to 4096 blocks can be filled
  - oldBlockHandling works like with /setblock, but with additional options: hollow to only fill the outer layer of blocks and fill the inner part with air, outline to fill the outer layer of blocks and ignore the inner part
  - Works similarly to /setblock
  - Usage: /fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] <dataTag>
  - Example: /fill 1001 3 1002 1011 5 992 wool 6 replace
  - Can filter certain blocks
    - Only if it’s used to fill in replace mode with “normal” blocks.
    - It does not work when filling with block entities.
    - Syntax: /fill [x] [y] [z] [x] [y] [z] [BlockName] [Data] replace [filterBlockName] [filterData]
- /particle
  - Spawns particles in a given area
    - It can also be relative to entities.
  - Usage: /particle <name> <x> <y> <z> <xd> <yd> <zd> <speed> [count] [player:entity]
  - Example: /particle lava ~ ~1 ~ 1 1 1 0.5 2 @e[type=Chicken]
  - List of particles: hugeexplosion, largeexplode, fireworksSpark, bubble, suspended, depthsuspend, townaura, crit, magicCrit, smoke, mobSpell, mobSpellAmbient, spell, instantSpell, witchMagic, note, portal, enchantmenttable, explode, flame, lava, footstep, splash, wake, largesmoke, cloud, reddust, snowballpoof, dripWater, dripLava, snowshovel, slime, heart, angryVillager, happyVillager, iconcrack_(ID), blockcrack_(ID), blockdust_(ID)_(DATA), barrier.
- /testforblocks
  - Compares two areas of a world
  - Example: /testforblocks 100 64 100 107 69 107 0 64 0 masked
- /trigger
  - Functions the same way as /scoreboard players set or /scoreboard players add, but can only modify objectives with the trigger criteria (referred to as "triggers") and can only modify the score of the player running the command
  - Can be used by non-operator players
  - For a player to run this command, the trigger must be enabled for that player
    - /scoreboard players enable <player> <trigger> will enable the specified player to use the specified trigger objective
    - Trigger availability is stored per player, per trigger
      - One trigger may be disabled for a player, but that player can use a different trigger
      - One player may be unable to use a trigger, but another player can use the same trigger
    - Disabled after the trigger has been used (must be re-enabled to use the trigger again)
  - Mostly for use with /tellraw
  - Syntax: /trigger <objective> <add:set> <value>
- /worldborder
  - /worldborder [set,center]
    - /worldborder set <sizeInBlocks> <timeInSeconds>
      - Used to set size of border. The first argument sets the size of the border and the second sets the speed of the border to expand or shrink
    - /worldborder [center] <x> <z>
      - Sets the center of where the border will be placed.
NBT Tags
- CanDestroy
  - Mostly for use in adventure mode
  - Items with this tag display the names of the blocks that they can destroy in the item tooltip
  - Example: /give @p minecraft:diamond_shovel 1 0 {CanDestroy:["minecraft:sand","minecraft:grass"]} to give a diamond shovel that can break grass and sand)
- CanPlaceOn
  - Allows placing of certain blocks against other blocks in adventure mode
  - Example: /give @p minecraft:stone 16 0 {CanPlaceOn:["minecraft:diamond_block"]}
- HideFlags
  - Allows hiding of certain parts of the tooltip
  - Bit field determining which parts of the tooltip to hide on an item. 1 for ench, 2 for AttributeModifiers, 4 for Unbreakable, 8 for CanDestroy, 16 for CanPlaceOn, and 32 for various other information (including potion effects, StoredEnchantments, written book generation and author, Explosion, and Fireworks).
  - Examples: Setting bit field to 3 would hide both ench and AttributeModifiers tags, and setting to 63 would hide everything.
- PickupDelay
  - The number of ticks before an item entity can be picked up.
  - Set to 32767 for items that can't be picked up
- ShowParticles
  - Option to show or hide all particles for a potion effect, while the 'Ambient' tag only shows fewer particles. Set to 1 to show, 0 to hide.
- Lock:"Secret"
  - A way to lock containers from being opened using NBT tags
  - Mostly useful for adventure maps in adventure mode
  - Containers can be unlocked by clearing their string for Lock
  - Locked containers can only be opened while holding anything renamed to the given string, item is not removed on use^[2]
  - The lock can be completely removed utilizing the command /blockdata
- BlockEntityTag
  - BlockItem instances can now hold a custom NBT tag that is merged into a block entity when it’s placed
  - Example: /give @p command_block 1 0 {BlockEntityTag:{Command:"/setblock ~ ~ ~ minecraft:diamond_block"}}
- rewardExp
  - Controls villagers giving xp for trading, set to true or false
- generation
  - Defines whether a written book is an "Original" a "Copy of Original" or a "Copy of a copy"
Gamerules
- logAdminCommands
  - Prevents command block output from being stored in chat logs. In multiplayer, also prevents player-initiated commands from being stored. Unrelated to commandBlockOutput, which is output into the visible chat.
- showDeathMessages
  - Prevents death messages like "[player] fell out the world" from appearing in the chat.
- randomTickSpeed [value]
  - A new gamerule that controls how often a random tick occurs. Influences how fast plants and crops grow, how fast pigmen spawn from portals, how fast farmland updates, how fast grass and mycelium grow and decay and more.
  - If set to 0, random ticks never occur.
Statistics
- stat.crouchOneCm
  - Detects how many cm the player has moved while crouching
- stat.sprintOneCm
  - Detects how many cm the player has moved while sprinting

- New objective criteria 'trigger
  - Acts like the dummy criteria
  - Mostly for use with /tellraw
- The ability to iterate over every scoreboard player with *
- Fake players with a name starting with # will never show up on the sidebar
- New /scoreboard subcommands: /scoreboard operation and /scoreboard test
  - The operation subcommand can apply arithmetic operation to scores (+ – * / %) and accumulate player scores
    - Example: /scoreboard players operation #teamscores redScore += @a[team=red] blueKills adds every red player's count of kills on blue to the red team's score of kills
  - The test subcommand can be used to test if a scoreboard value is between a min and a max value
    - Example: /scoreboard players test #global anObjective 12 19 checks whether the global score of the given objective is between 12 and 19, inclusive
- Different teams can now have different objectives displayed in the sidebar
  - Example: /scoreboard (referring to team color, not team name)
- Teams can now have settings on how the nametags are to be shown - /scoreboard teams option red nametagVisibility hideForOtherTeam Also possible: hideForOwnTeam, never, always (default)
- Testing for scores now also works in @e entity selector
- Added scoreboard team property to disable death messages: /scoreboard with options never, hideForOtherTeams, hideForOwnTeam, always
- Command /scoreboard players (add|enable|get|list|operation|remove|reset|set) can now filter by NBT data
Spectator game mode
- Usage: /gamemode spectator, /gamemode sp or /gamemode 3
- No interaction with the world
  - Player can move through any entity or block without interfering with it (commonly referred to as 'noclip')
  - Collecting or using items is impossible, as is placing, destroying or interacting with blocks in any way
  - Viewing inventories and GUIs is possible, but it is not possible to interact with them
    - The HUD is disabled, except for the crosshairs when looking at a mob.
  - Player selectors (in commands) will target spectators
    - Using /give on a spectator will cause the item(s) to drop at their location.
  - Spectators are not noticed by mobs, and do not trigger spawners or spawning
    - A spectator's presence keeps a mob from despawning
  - Only the Void and /kill can damage a spectator
- Flying mode
  - Landing is not possible—the player can fly through the ground
  - The mouse scroll wheel, the sprint key, and the slowness and swiftness effects all affect the flying speed
- First-person view through another player or mob's eyes
  - Left-clicking an entity locks the player's position and camera to the entity's
  - The spectator cannot control where the entity moves or looks
  - Certain mobs have different vision

- Worlds can be shared to LAN in spectator mode

World Generation

Underground
- Granite, andesite and diorite generate in pockets within stone terrain
  - Slightly larger size and abundance than gravel
  - Pockets generate before ores, so they don't reduce their frequency (ores can generate inside these pockets)
Customized world type
- Highly customisable terrain generation
  - To use, press create new world then ‘world type: customized’ and then press the 'customize' button
  - There are 4 pages to customize the world
  - Page 1: customizes generation of structures, chance of lake generation, size of certain structures, and biome type and size, and sea level
    - There are 17 customization options which affect whether generated structures will spawn in, as well as other environmental factors. Some of these presets are Yes/No inputs or sliders.
      - Sea level height, toggles for cave, village, temple, dungeon, water lake, lava lake, stronghold, mineshaft and ravine generation, sliders to control water lake, lava lake and dungeon rarity, toggle to turn oceans into lava oceans, biome selection, biome and river size sliders
  - Page 2: customizes the ore distribution for dirt, gravel, granite, diorite, andesite, coal, iron, gold, redstone, diamond and lapis
    - Rarity, height range and vein size
  - Page 3 & 4: Expert customization of the terrain generation
    - There are 16 customization options which can be used to affect various aspects of Minecraft's terrain generator. These can be changed by moving sliders or by typing in values directly
      - Main Noise Scale X/Y/Z to smooth out terrain, larger values for smoother terrain; Biome scale/depth weight and Biome scale/depth offset to stretch/squash terrain vertically based on the biomes default height settings; Upper/lower limit scale to make terrain more solid/riddled with holes, depending on how close the values are to each other; Height Stretch to pull terrain upward, with smaller values causing more extreme stretching; Height scale, coordiange scale, depth base size, depth noise exponent, depth noise scale
- There are seven presets
  - Water World, Isle Land, Caver's Delight, Mountain Madness, Drought, Caves of Chaos, Good Luck
- A button to randomize the various values
- Uses the 'generator-settings' string known from superflat presets for server.properties and world data
- Generate structures button disappears when selected

Slime Block
- Players and mobs that land on their top side will bounce, like on a trampoline
  - Bounce rebound velocity is scaled by impact velocity, can reach up to 60%
  - Currently does not affect item entities
- Prevents fall damage
- Walking on it is slower than walking on soul sand, close to one's speed whilst sneaking
- Crafting recipe: 9 slime balls
  - Can be crafted back into 9 slime balls
- Connected to sticky pistons, slime blocks will now push and pull blocks beside them when moved by pistons
  - Connected to normal pistons, slime blocks will only push blocks, but not pull them
  - Coded by KaboPC and Panda4994^[3]^[4]
  - Up to 12 slime blocks connected to a piston in any arrangement can be moved as long as the following conditions are met: blocks do not disrupt the chain, non-moveable blocks are not in the way or slime blocks are not attached to the piston itself
  - Follows all the rules that pistons follow, for example blocks which can normally be moved by pistons can be moved if attached to slime blocks
  - Allows for more contraptions, from new redstone clocks, moving devices, farming etc
- Extending a piston with a slime block on top of it will launch the entity (mobs, players, items, launched arrows etc) into the air^[5]
Barrier
- Acts like a full block but is completely transparent
- Can transfer redstone signals and allows blocks to be placed on it
- Can only be destroyed in Creative mode
- Can be obtained using /give @p minecraft:barrier

Villagers
- When struck by lightning, villagers turn into witches
- Villagers will now only breed when willing
  - The first time a specific trade is done, the villager will become willing, any other time there's a 1 in 5 chance the villager will become willing
  - When a baby villager is born, both parents lose their willingness
  - Villagers become willing to breed by consuming food: 3 bread or 12 potatoes or 12 carrots
  - Finding out a villager's willingness in survival is difficult: The only tell is the amount of xp they give when trading; Normal trading yields 3-6 experience points, trading and making a villager willing yields 8-11 experience points
- Changes to villager AI
  - Villagers will now harvest, collect and replant grown potatoes, wheat and carrots
  - Villagers will craft wheat into bread
  - Villagers will share food with fellow villagers
