Gameplay

 * Achievements

 * Obtained by crafting an enchanted golden apple.
 * Requires first obtaining Getting an Upgrade.
 * Enchantments
 * New enchantment Depth Strider.
 * Allows the player to move faster while in water.
 * Can only be applied to boots in survival up to level III.
 * Spectator game mode
 * It can only be accessed and reversed via, either using ,  , or.
 * It is the default gamemode on the debug world type.
 * Like in creative mode, only the Void and can damage/kill a spectator.
 * Their player model in the inventory is completely invisible.
 * Free roaming:
 * If the world border isn't right next to the edge of the world, then it has no effect on spectators, apart from the warning colors displaying.
 * The player can fly through solid blocks (noclip).
 * If the head of the player is inside of a block, then an x-ray like effect will happen, where every block is invisible until it is adjacent to an air block, or the model does not occupy a full space.
 * The mouse scroll wheel, the sprint key, the slowness and swiftness effects, all affect the flying speed.
 * Night vision effects still affect spectators.
 * First-person view through another player or mob’s eyes.
 * Includes non-mob entities like paintings or minecarts
 * Creepers, spiders and endermen apply a specific shader while spectating through each of them.
 * Spectating through a player shows the respective HUD.
 * Pressing the dismount key (shift by default), returns the player to flying mode.
 * Viewing privileges:
 * Cannot catch on fire, so their view isn't obstructed.
 * Spectators can see other spectators as disembodied translucent heads, with the corresponding player skin.
 * All invisible players/mobs appear visible, but translucent.
 * An optional held hotkey shows bright outlines on all players.
 * Can be color-coded to teams.
 * Spectators can look at the inventories of blocks like chests and entities like minecarts with chest.
 * This includes their own inventory.
 * Automatic targeted teleportation-spectators have a UI to teleport to other players.
 * The UI can only be brought up and interacted with, by the number keys or middle mouse click.
 * But the scroll wheel can still scroll through the different options.
 * It is similar to the regular hotbar in creative, but contains special icons that appear to be different items, like barrier blocks or old player heads.
 * If there is at least 1 team set up, the UI distinguishes between teleporting to an individual or teleporting to a member of a specific team.
 * Otherwise it defaults to an all-inclusive, alphabetical list of players (except for fake players).
 * Team members are still sorted the same way, inside their own lists.
 * Both the player and the team icons are color-coded with respect to the team color.
 * The player icons that teleport are rendered with the skin of the head of the player, and resemble the way the player heads were displayed before 1.8.
 * If there are more than 8 players/teams available to teleport, slots 1 and 8 will display right and left arrows respectively, to scroll through.
 * The arrows look very similar, as the ones used in the resource pack menu and the server list.
 * The right and left arrow will not show up, if there are no more players to the right or left of the list respectively.
 * There is always an option in slot nine to close the menu.
 * Looks like a barrier block item.
 * Teleportation works across dimensions.
 * Limitations to spectators-spectators cannot:
 * Load terrain.
 * Interact with blocks or entities, apart from spectating through the latter.
 * Interact with any inventory (including their own).
 * Look at the inventory of other players/mobs, apart from the hotbar items of players.
 * Control the behavior of any entity they spectate through.

Command format

 * Target selectors
 * Targets all entities.
 * Can specify the type of entity by entity ID, to either include or exclude with, to only apply it to chickens or  , to apply it to every entity that isn't a skeleton.
 * Example:
 * Kills all chickens within a radius of 50 blocks.
 * Any entity within a radius of 5 blocks will be teleported five blocks in the air.
 * Commands
 * Allows commands to be run from the position of specified entities.
 * A  argument allows the  command, to run only if a block is detected at a specific location relative to the target.
 * Syntax:
 * {{cmd|execute    detect     criteria (referred to as "triggers"), and can only modify the score of the player running the command.
 * Allows non-op players to use s as well as to prevent its abuse.
 * Can be used by non-operator players.
 * For a player to run this command, the trigger must be enabled for that player.
 * {{cmd|scoreboard players enable }} will enable the specified player to use the specified trigger objective.
 * Trigger availability is stored per player.
 * 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 {{cmd|tellraw}}.
 * Syntax: {{cmd|trigger  }}.
 * {{cmd|replaceitem| ...}}
 * Can replace items in any inventory, including the inventories of mobs such as villagers.
 * Syntax:
 * {{cmd|replaceitem entity  [amount] [data value]}}
 * {{cmd|replaceitem block    [amount] [data value]}}

 * {{cmd|blockdata}}
 * Modifies NBT data at a specific coordinate, the ,   or.
 * will copy every block (default).
 * will copy only non-air blocks.
 * will remove specified blocks.
 * It can additionally accept the tags:,   or.
 * will move the selection from the first location to the second location, which may overlap.
 * will force the cloning operation, even if the areas overlap.
 * only needs to be specified if using.
 * Syntax: {{cmd|clone      <z2> <x> <y> <z> [mode]}}.
 * Example: {{cmd|clone 1001 3 1002 1011 3 992 1001 5 992 masked}} Targets the cuboid volume defined by the opposite corners: [1001,3,1002],[1011,3,992] and clones it such that the old corner coincides with the destination (and orientation) at [1001,5,992].
 * {{cmd|fill}}
 * Fills a given volume with a specified block.
 * It cannot replace or fill block entities with specific data tags.
 * Up to 32768 blocks can be filled.
 * Syntax: {{cmd|fill <x1> <y1> <z1> <x2> <y2> <z2> <TileName> [dataValue] [oldBlockHandling] [dataTag]}}.
 * The  parameter determines the fate of the blocks, occupying the volume about to be filled,
 * It takes the same values here as it does in {{cmd|setblock}}:,   and   – as well as two additional values:
 * to only fill the outer layer of blocks, and fill the inner part with air,
 * to fill the outer layer of blocks, and keep the inner part the same.
 * Example: {{cmd|fill 1001 3 1002 1011 5 992 wool 6 replace}} Fills the given area with pink wool.
 * It can be made to filter specified blocks.
 * Syntax: {{cmd|fill [x] [y] [z] [x] [y] [z] [BlockName] [Data] replace [filterBlockName] [filterData]}}.
 * {{cmd|testforblocks}}
 * Compares two areas of a world, to check if they share the same blocks on the same configuration (including orientation).
 * The mode can be set to  or
 * is the default, while  will ignore air blocks.
 * Syntax: {{cmd|testforblocks <x1> <y1> <z1> <x2> <y2> <z2> [mode]}}.
 * Example: {{cmd|testforblocks 100 64 100 107 69 107 0 64 0 masked}}.
 * {{cmd|stats <entity{{!}}block> ...}}
 * Will update a scoreboard objective for an entity, based on the number of entities/blocks which have been affected or detected by the command.
 * Syntax:
 * {{cmd|stats entity }}
 * {{cmd|stats block [x] [y] [z] }}
 * Alternative and more useful way of interacting with the  tag.
 * After the  there are currently 5 possible stats that can be updated: ,  ,  ,   and.
 * Example: {{cmd|stats entity @a set AffectedBlocks @a Test}} Updates a scoreboard objective named 'Test' for all players whenever a command is performed relative to them. The objective will update by the number of blocks affected by the command. Since the stat was set to , this means that if the command is {{cmd|fill}}, it will update the objective for whoever is running the command (@a) by the number of blocks filled.
 * {{cmd|worldborder}}
 * {{cmd|worldborder <set,add,center,damage,warning,get>}}
 * {{cmd|worldborder set <sizeInBlocks> <timeInSeconds>}}
 * The first argument sets the size of the border (both the width and depth) in blocks, and the second sets the speed of the border when it expands or shrinks.
 * The shape of the border can only be a square.
 * {{cmd|worldborder add <sizeInBlocks> <timeInSeconds>}}
 * Adds blocks to the current size of the world border. It can use negative numbers to subtract to the size of the border.
 * {{cmd|worldborder center <x> <z>}}
 * Sets the center of where the border will be placed.
 * {{cmd|worldborder damage <buffer{{!}}amount>}}
 * The amount parameter customizes the damage rate, while outside the border.
 * The buffer parameter customizes the amount of blocks the player can go outside of the border, before starting to take damage.
 * {{cmd|worldborder warning <time{{!}}distance>}}
 * Allows the player to customize how far the player has to be from the border, and/or the amount of time a shrinking border would take to reach the player, before it starts showing the warning.

 * {{cmd|title}}
 * Can make text display on the player screen, in the form of a title and/or subtitle using JSON.
 * {{cmd|title @a title }}

 * {{cmd|title @a subtitle }}
 * Sets the text of the subtitle (optional).
 * {{cmd|title @a times <fadeIn> <fadeOut>}}
 * Sets the fade in, fade out and stay in time for the title and subtitle. This is in game ticks (1/20th of a second).
 * {{cmd|title @a clear}}
 * Removes the titles and subtitles off the screen immediately.
 * {{cmd|title @a reset}}

 * Example: {{cmd|1=particle lava ~ ~1 ~ 1 1 1 0.5 50 normal @e[type=Chicken]}} Creates 50 lava popping particles, centered one block above the block/entity running the command, spreading around a radius of 1 block, with a speed of 0.5, relative to all chickens in that world.
 * The  argument can be set to   to display particles, even if a player has his 'Particles' toggle set to Minimal or Decreased.
 * List of particles:,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,  ,.
 * Gamerules
 * Prevents command block output from being stored in chat logs. In multiplayer it also prevents player-initiated commands from being stored. Unrelated to commandBlockOutput, which is output into the visible chat.
 * If set to false, player-run commands will not show a message.
 * Prevents death messages like "[player] fell out the world" from appearing in the chat.
 * This enable/disable reduced information on the F3 debug screen, like in video settings.
 * Set to 1, overrides the 'reduced debug info' setting in clients.
 * Controls how often a random tick occurs
 * Random ticks influence the next things: pigmen spawning from portals, all plant growth, leaf decay, fire spread, ice melting, grass/mycelium spread and farmland hydration.
 * If set to 0, random ticks never occur.
 * The ability to create custom gamerule variables.
 * These are fake gamerules which don't affect gameplay by themselves, but can be used with {{cmd|stats}} with the new  argument, to update a scoreboard objective based on the value of that gamerule.
 * Declare using: {{cmd|gamerule <newRuleName> }}.
 * Access using: {{cmd|gamerule <newRuleName>}}.
 * Scoreboard
 * New objective criteria for team-specific kills, e.g.:.
 * New objective criteria '.
 * Acts like the  criteria.
 * Can be interacted with using the {{cmd|trigger}} command.
 * Mostly for use with {{cmd|tellraw}}.
 * The ability to iterate over every scoreboard player with.
 * This will also affect players who are offline.
 * Fake players can be created when run in a command block.
 * They only exist through the distinct scoreboard operations and functions, and are merely virtual within the context of the gameplay.
 * They do not bring the player count up on servers and do not appear on any player listing. Both in the server list and in the tab list while online.
 * Fake players with a name starting with {{cmd|#}}, will never show up on the scoreboard sidebar.
 * New {{cmd|scoreboard}} subcommands: {{cmd|scoreboard reset}}, {{cmd|scoreboard operation}}, {{cmd|scoreboard test}} and {{cmd|scoreboard enable}}.
 * The  subcommand can reset all objectives for a player or reset a player's objectives one by one.
 * Example: {{cmd|scoreboard players reset @a anObjective}} Resets the scores of an objective named anObjective for all players in the world.
 * The  subcommand can apply arithmetic operation to and between scores (+ – * / % < > =) and therefore accumulate player scores.
 * Example: {{cmd|1=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.
 * Can be tested with a comparator to see if two scores are greater than, smaller than or equal to each other.
 * The  subcommand can be used to test, if a scoreboard value is between a min and a max value.
 * Example: {{cmd|scoreboard players test #global anObjective 12 19}} Checks whether the global score of the given objective is between 12 and 19, inclusive.
 * The  subcommand can be used to enable a   objective.
 * Example: {{cmd|scoreboard players enable Trigger_a}} Enables a  named Trigger_a.
 * Different teams can have multiple objectives displayed in the sidebar.
 * Example: {{cmd|scoreboard|objectives setdisplay sidebar.team.yellow anotherObjective}} This refers to the team color, not the team name.
 * Testing for scores also works in  entity selector.
 * Added scoreboard team property to disable name tag visibility: {{cmd|scoreboard teams option nametagVisibility}} with options,  ,   and   (default).
 * Added scoreboard team property to disable death messages: {{cmd|scoreboard|teams option deathMessageVisibility}} with the options:,  ,   and   (default).
 * Command {{cmd|scoreboard|players}} can now filter by NBT data.
 * NBT Tags
 * Block entities item form can hold custom NBT tags that are merged to the specified block entity when they're placed.
 * Example: {{cmd|give @p command_block 1 0 {BlockEntityTag:{Command:"{{cmd|setblock ~ ~ ~ minecraft:diamond_block}}" }} }} Gives a command block that, when placed, will automatically have the command {{cmd|setblock ~ ~ ~ minecraft:diamond_block}} set.
 * A way to lock containers from being opened by players outside of creative.
 * Mostly useful for adventure maps in adventure mode.
 * Containers can be unlocked by clearing their string for the tag.
 * Locked containers can only be opened while holding anything renamed to the given string.
 * The item is not removed on use.
 * 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: {{cmd|give @p minecraft:diamond_shovel 1 0 {CanDestroy:["minecraft:sand","minecraft:grass"]} }} Gives a diamond shovel that can only break grass and sand.
 * If an invalid item name is put in, it will display as "missingno" under the "Can Break" list.
 * Allows placing of certain blocks against other blocks in adventure mode.
 * Example: {{cmd|give @p minecraft:stone 16 0 {CanPlaceOn:["minecraft:diamond_block"]} }} Gives a block of stone that can only be placed on diamond blocks.
 * If an invalid item name is put in, it will display as "missingno" under the "Can Be Placed On" list.
 * The number of ticks before an item entity can be picked up.
 * Set to 32767 for items that can't be picked up.
 * Defines whether a written book is an Original a Copy of Original or a Copy of a Copy.
 * Allows hiding of certain parts of the tooltip.
 * Bit field determining which parts of the tooltip to hide on an item. 1 for, 2 for  , 4 for  , 8 for  , 16 for   and 32 for various other information (including potion effects,  , written book   and  ,   and  ).
 * Examples: Setting the bit field to 3 would hide both  and   tags, and setting it to 63 would hide every tag.
 * Contains the item data of the item currently held in the player's hand.
 * Added to compact the process of testing if a player is holding a specific item.
 * Previous method required nine commands (one per slot in the hotbar); now requires only one command.
 * Entities without AI will not attack players, move or rotate on their own, and do not despawn.
 * They also do not respond to gravity or collision with other mobs, but can still take damage, die, be caught on fire, and ride other entities.
 * Setting to 1 disables an entity's AI.
 * Controls villagers giving xp for trading.
 * Set to 1 for xp or 0 for no xp.
 * Option to show or hide all particles for a potion effect, as opposed to the  tag, which only show fewer particles.
 * Set to 1 to show, 0 to hide.
 * Determines whether sound is produced by an entity, such as idle and hurt sounds.
 * Setting to 1 disables sound effects.
 * Allows a command block or sign to increase a certain score in the scoreboard when it runs successfully.
 * The command will increase the score based on the number of items/blocks/entities/successes.
 * For example, a command block with this tag running a command which affects items (e.g. ) will cause it to update the score based on the number of items given.
 * Syntax:.

 * 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, Coordinate scale, Depth base size, Depth noise exponent and Depth noise scale.
 * There are seven presets.
 * Water World, Isle Land, Caver's Delight, Mountain Madness, Drought, Caves of Chaos and Good Luck.
 * Each page has a button to randomize the various values and a button to reset to default values.
 * Uses the 'generator-settings' string known from superflat presets for server.properties and world data.
 * Generate structures button disappears when selected.
 * Debug mode world type
 * Useful for resource pack makers.
 * Hold and cycle through "World Type" option to select it.

 * All worlds with grassless dirt blocks will seamlessly change over to coarse dirt, as it uses the same block ID and data value as the original grassless dirt block.
 * Slightly darker texture than regular dirt.
 * Silk touch is not required for obtaining it in survival.
 * Tilling coarse dirt with a hoe will turn it to regular dirt.
 * Crafting recipe: dirt and gravel in a 2×2 checkered pattern yields four coarse dirt.

 * This negates all fall damage.
 * Holding will negate the rebound, while still negating the fall damage.
 * Bounce rebound velocity is scaled by impact velocity.
 * Height can reach up to 60% of initial height, which implies a great restitution coefficient.
 * Does not affect falling item entities.
 * Walking on it is slower than walking on soul sand and close to one's speed while sneaking.

 * Worn armor no longer gets colored when the respective mobs/players are hurt.
 * Villagers
 * Now have a system for distinguishing professions (colored clothes) and careers.
 * The career now shows in the trading GUI, instead of just "villager".
 * Farmer (Brown robe): Farmer, Fisherman, Shepherd and Fletcher / Librarian (White robe): Librarian / Priest (Purple robe): Cleric / Blacksmith (Black apron): Armorer, Weapon Smith and Tool Smith / Butcher (White apron): Butcher, Leather worker.
 * When struck by lightning, they turn into witches.
 * Have a head slot where helmets and other items can be applied.
 * 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 it will become willing again.
 * 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 achieved by counting the amount of xp given when trading:
 * Normal trading yields 3–6 experience points.
 * Trading that makes the villager willing yields 8–11 experience points.
 * Changes to the farmer (profession) villager AI:
 * Harvest, collect and replant grown potato, carrot & wheat crops.
 * Craft wheat into bread.
 * Share food with fellow villagers.
 * Wither skeletons
 * Hitbox has been changed from 2.5 to 3 blocks.
 * Zombie pigmen
 * Adult zombie pigmen will forgive after a short time (and lose the aggro speed boost), but will continue to attack until the player escapes their aggro distance.
 * Endermen
 * Walk slightly faster.
 * Blazes
 * Blazes will shoot the player even if there are solid blocks between them.
 * Silverfish
 * Silverfish will stop occasionally before moving again (similarly to most mobs).
 * Sheeps
 * Drop mutton when killed.
 * Giants
 * Armor on giants is now rendered.
 * Iron golems
 * No longer attack the player while in creative.
 * Attack and are by the next mobs without provocation: Zombies, skeletons, creepers, spiders, cave spiders, slimes, magma cubes and blazes.
 * Snow golems
 * Snow golems below layer 64 no longer leave a trail of snow.
 * Wolves
 * Tamed and untamed wolves attack skeletons and wither skeletons without provocation, similar to how untamed wolves attack sheep in the wild.
 * Tamed Ocelots & Tamed Wolves
 * Display a death message if named with a name tag.
 * Skeletons & wither skeletons
 * Run away from wolves instead of fighting back.
 * Spiders & cave spiders
 * Can no longer draw line of sight through opaque blocks.
 * Slimes & magma cubes
 * Swim as a result of the update to the new AI.
 * Randomly change direction every so often, reducing the chance of them getting stuck at walls or corners.
 * Randomly despawn over time if no player is within a 32 meter range.
 * Appear to jump a bit more randomly.
 * When named and attacked, each new slime will keep its given name.
 * Aggroed zombie pigmen & endermen
 * Now pathfind, as a result of the update to the new AI.
 * Creepers, spiders & enderman
 * Apply a specific shader while spectating through each of them.
 * Zombies, skeletons & creepers,
 * Drop their respective mob head, when killed by a charged creeper.
 * Iron golems, snow golems & withers
 * Can be spawned by arranging the blocks, in equivalent rotations of the default.
 * This does not affect the orientation of the spawned mob.
 * Can be spawned using dispensers, which place the final block in the appropriate place.
 * This does not affect the orientation, either.
 * Zombies, zombie pigmen, skeletons, wither skeletons, other creepers & witches
 * Run away from creepers that are about to explode.
 * Baby animals (sheep, pig, cow, chicken, cat, dog, horse & rabbit)
 * Growth can slowly be accelerated using the animal's breeding item: Each use takes 10% from the remaining time to grow up.

Non-mob entities

 * All items
 * The dropped item entities now face the player in all three axis on fast graphics.
 * Arrows
 * Behave differently underwater.
 * They will lose all velocity after a few blocks and slowly fall.
 * Fire arrows will be immediately extinguished.
 * Minecarts with TNT
 * Can be ignited with a flame enchanted bow.
 * Explosions no longer stack linearly.
 * Now they stack following a function with a horizontal asymptote
 * The domain is the amount of minecarts and the range is the explosion strength.
 * This puts a hard limit on the possible explosion strength.
 * Item frames
 * Can be seen from further away.
 * Items in item frames can now face eight different directions, instead of just four.
 * As long as the frame remains placed, it remembers the orientation of the last item it held and uses that orientation for the next item it holds.
 * Item frames can give off a signal detected by comparators, based on the direction the present item is facing.
 * Signal strength is as follows: 0: empty; 1: item; 2: item rotated once; 3: item rotated twice; ...; 8: item rotated 7 times.
 * The signal is independent of the specific item inside.
 * Paintings & item frames
 * Improved position handling of both.
 * Can no longer intersect with each other or one another on the same block face.
