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>
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.
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
- stat.timeSinceDeath
  - Detects how much time has passed (in ticks) since the player's last death
Scoreboards
- The ability to reset objectives one by one
  - Example: /scoreboard players reset <player> [objective]
- New objective criteria for team-specific kills, e.g.: teamkill.red, killedByTeam.blue
- 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
    - Creeper applies the new creeper.json shader
    - Endermen applies the invert.json shader
    - Spider and Cave Spider apply the new spider.json shader
  - Viewing oneself using F5 shows the entity

- On the right hand side, a display shows up if you are looking at a block, giving various pieces of information and NBT data about it.
  - Looking at a door and redstone shows you the state of the block
    - Door: which way it is facing, if it is open, which half you are looking at, if it is powered, and what side the hinge is
    - Redstone: power direction (up, down, side, none) for all compass directions (north, south, east, west) and power level
  - Not 100% complete, data for a lot of blocks still missing
- Currently missing LC value
Block IDs
- Occurences of blocks/items now need to be named ids; old ids slowly being phased out
- NBT data in commands can now use block/item names in place of numerical ids
  - Example: id:"minecraft:stone"

- Superflat presets also use the new named id format
Internal block handling
- Now internally use states instead of metadata
- Metadata will still be used for a while
- Block states of the block being looked at will now be displayed on the F3 menu - Examples: redstone, door
- Internally, metadata no longer needs to be calculated out of the 4 bit data value, instead the values of specified properties can now be easily gotten and set
Chat

- Messages are now either chat, system or action bar messages
- Action bar messages are always shown, chat and system messages are only shown if chat settings are configured that way
- Entities now have tooltips in certain chat instances when hovered over
  - These appear when hovered over an entity's name in chat (e.g. the success message for /kill)

- When items are collected, rather than "zooming" into the player's chest, it appears to move to the player's feet instead.
Resource packs
- Block models in resource packs can now be customized
  - Replaces the files in /assets/minecraft/models/
  - Block format: UV has to be [0,1] (Textures cannot "borrowed" from neighbouring block textures), planes need to have 1 axis 'identical' (so aligned to either x,y,z), plane rotation can only be -45/45 on a single axis, from/to and uv coordinates are in 'pixelspace' (multiples of 1/16th of a block)
  - Rotation is in increments of 22.5 degrees on a single axis
  - Being able to override not just a model, not just a block's model, but an individual block variant's model
  - F3+T and F3+S now reload models

  - Example: /tp @p ~ ~ ~ ~20 ~40 teleports the player so that he faces 20 degrees to the right and 40 degrees downwards
Target Selectors
- Now supports cubic areas
  - Example: @e[x=0,y=0,z=0,dx=10,dy=10,dz=10] gets all entities between 0,0,0 and 10,10,10
- New radius value usable in target selectors, based on the block centre
