1.13 is an upcoming major update with no set release date. It will focus mainly on bug fixes, technical features, and optimisation.[1][2]

Additions

General

Data packs
  • Like resource packs, but for loot tables, advancements, functions, structures, recipes and tags.
    • Used by placing them into the datapacks folder of a world.
  • Data packs are .zip files or folders, with a pack.mcmeta in the root. See: Tutorials/Creating a resource pack#pack.mcmeta. The packs are located in (world)/datapacks/.
  • Structures will load from (world)/generated/structures/(namespace)/(file).nbt before checking data packs.
    • However, this directory should not be used to distribute structures. Instead, move these files into data packs.
  • Reloadable using /reload.
  • Structure: pack.mcmeta, data folder containing a namespace folder determining the namespace of its contents
    • A namespace should only contain the following symbols: 01​​234​5​6​78​9abcdefghijklmnopqrstuvwxyz-_
    • Inside the namespace folder, there can be folders for functions, loot_tables, advancements, structures, recipes and tags.
Tags
  • Items, blocks and functions can be "tagged" with an ID.
    • Block tags can be used when testing for blocks in the world.
    • Items tags can be used when testing for items in inventories.
    • Function tags can be used when calling functions using commands or advancements.
      • Functions tagged in minecraft:tick will run every tick at the beginning of the tick.
  • Tags are created using data packs in data/(namespace)/tags/blocks, data/(namespace)/tags/items, and data/(namespace)/tags/functions.
    • When overriding a tag from a different data pack, you can choose to replace or append.
      • By default all tags append if another data pack created the tag.
      • Adding "replace": true to your tag definition will make the tag overwrite instead.
    • For example: data/(namespace)/tags/blocks/foo.json
    • This will create a block tag called (namespace):foo.
    • The json file contains a list of all blocks that should be "tagged".
      • This list can also contain other tags of the same type.
        • You can add for example #foo:bar in a tag value list to reference another tag called foo:bar.
        • Self referencing is not possible.
  • There are 10 default tags for both items and blocks: buttons, carpets, doors, logs, planks, saplings, stone_bricks, wooden_buttons, wooden_doors and wool
  • There is one extra default tag for blocks: flower_pots
  • Advancement item predicates now support item tags.
Options
  • FS (Fullscreen) Resolution
    • Is used to change the resolution.
  • An option in chat settings to toggle automatic command suggestions (defaults on, otherwise hit tab to bring them up).
  • Options when editing a world to make a backup and open the backups folder.

Blocks

  • Trapdoors, buttons and pressure plates made from all six types of wood.
  • A pumpkin block, without the face. The previous pumpkin block has been renamed "Carved Pumpkin".
    • Right-clicking a pumpkin block with shears will turn it into a carved pumpkin and make it spit out 4 pumpkin seeds.

Commands

General
  • A command UI when typing commands in the chat.
    • Different components of commands will be displayed in different colors.
    • Errors will be displayed in red without having to run the command.
  • An nbt argument in target selectors.
  • A new command parsing library known as brigadier.
Coordinates
  • Added a new local coordinate type in commands using ^.
    • When specifying coordinates in a command, you can now use ^ to specify local coordinates instead of world coordinates.
    • The axes used for local coordinates are relative to the rotation of the executing entity.
    • Like world coordinates, they are measured from the base of an entity.
    • The syntax is: ^left ^up ^forwards
    • left/up/forwards is the amount of blocks in the specified direction.
  • Tab-completing coordinates when not targeting a block will suggest ~ ~ ~ again.
Specific commands
/data
  • A command that allows the player to get, merge, and remove entity and block nbt data
  • /data get block <pos> [<path>] [<scale>]
    • Will return the NBT data from the block at pos as its result (if a path is specified). A path can be specified to only retrieve that nbt data, but this is limited to numeric tags. An optional scale can be provided to scale the number retrieved.
  • /data get entity <target> [<path>] [<scale>]
    • Will return the NBT data from one target entity as its result (if a path is specified). A path can be specified to only retrieve that nbt data, but this is limited to numeric tags. An optional scale can be provided to scale the number retrieved.
  • /data merge block <pos> <nbt>
    • Will merge the block nbt data at pos with the specified nbt data.
  • /data merge entity <target> <nbt>
    • Will merge the entity nbt data from target with the specified nbt data. Merging player nbt data is not allowed.
  • /data remove block <pos> <path>
    • Will remove nbt data at path from the block at pos.
  • /data remove entity <target> <path>
    • Will remove nbt data at path from one target entity. Removing player nbt data is not allowed.
  • Data paths look like this: foo.bar[0]."A [crazy name]".baz.
    • foo.bar means foo's child called bar.
    • foo[0] means element 0 of foo.
    • "quoted strings" may be used if a name of a key needs to be escaped.
  • Examples of old commands:
  • Examples of new functionalities:
    • /data get entity @e[type=pig,limit=1] Saddle 2
    • /data remove block 17 45 34 Items
/datapack
  • A command to control loaded data packs.
  • Has the following subcommands:
    • enable <name> - will enable the specific pack.
    • disable <name> - will disable the specific pack.
    • list [available|enabled] - will list all data packs, or only the available/enabled ones.
  • Data packs are enabled by default, but if you disable it you can re-enable it with these commands:
    • enable <name> - will enable the specific pack, putting it in its default position.
    • enable <name> first - will enable the specific pack, putting it before any other pack (lowest priority)
    • enable <name> last - will enable the specific pack, putting it after any other pack (highest priority)
    • enable <name> before <existing> - will enable the specific pack, putting it before (lower priority) <existing> pack
    • enable <name> after <existing> - will enable the specific pack, putting it after (higher priority) <existing> pack

Items

  • An item form for bark blocks for all six types of wood.
  • An item form for petrified oak slab - the old wood slab that acts like a stone slab.
  • An item form for smooth quartz, smooth red sandstone, smooth sandstone, and smooth stone.
  • An item form for red and brown mushroom blocks and mushroom stems.
  • A debug stick to cycle between different block states.
    • Left clicking cycles through states; right clicking cycles through values. Shift clicking will cycle through the states or values in reverse order.

Changes

General

The "flattening"
  • Numeric block metadata completely phased out in favor of block states.
  • Split, merged, created, deleted, and renamed a lot of blocks, blockstates and items.
    • Blocks and items previously differing because of damage value have gotten their own id, for example white_wool instead of wool:0
    • Damage has been moved to the tag tag and is only used by tools and armor; maps use a map tag.
    • Files and commands no longer use data or set_data.
  • Structures do not run an upgrade path for this.
    • To update your structures, load them all in 1.12, then update to 1.13 and save all structures again.
Recipes
  • Custom recipes are now loaded from data packs in data/(namespace)/recipes/(name).json
  • Turning off the vanilla data pack will also remove all recipes.
  • Recipes can now refer to a tag instead of an item.
Creative Inventory
Death Messages
  • Added death message for when the player is blown up by a bed in the nether or end
    • "Player was killed by [Intentional Game Design]"
      • Clicking on "[Intentional Game Design]" opens a link to MCPE-28723
Statistics
  • Statistics are being updated.
Other
  • Game library updates
    • Upgraded to LWJGL 3
  • Loading or creating a world shows the percentages of the loading stages.
    • Preparing spawn area now shows as a loading stage.

Blocks

  • The upper limit of the block ID has dissappeared.
  • Blocks which used to have no bottom texture (like repeaters, comparators, torches, etc.) now have a bottom texture, not including redstone wire.
  • Flicking a lever on now displays redstone particles.
  • Blocks with a collision box now have matching bounding boxes.
    • Affected: anvils, cauldrons, hoppers, fences, iron bars, glass panes, filled ender portal frames, vines, lily pads, stairs, brewing stands, and pistons
    • Updated the collision box of anvils and hoppers.
    • Does not affect blocks with a collision box smaller than their model, such as soul sand and snow layers.
  • Beds now require a block below it as a support. Previously this was only required when placing the bed and the block could be destroyed afterwards without the bed being destroyed.
  • Chests and trapped chests can be put directly next to their double variants instead of requiring one block between them.
    • Shift right-clicking a chest or trapped chest next to a chest or trapped chest respectively will not make the two chests or 2 trapped chests combine into a double chest or double trapped chest.
  • Placing pumpkins and fence gates no longer requires a block below them.
  • Silverfish-Infested blocks will now break instantly, no matter the tool.
  • Bark can now be crafted. 4 logs in a square yield 3 bark.
  • Vines can now be placed on the bottom of blocks.

Entities

Item frames
  • Item frames can now be put on floors and ceilings.

Commands

General
  • Commands and functions are much faster and more efficient.
  • Most commands are now more case-sensitive. Lowercase is preferable wherever possible.
    • For example, this is no longer allowed: /scoreboard ObJeCtIvEs ...
  • The output signal of a command block used to be its "success count", but now is its "result".
Command UI
  • A new prototype for the command UI.
Functions
  • Functions are now completely parsed and cached on load.
    • This means if a command is incorrect for any reason, the player will know about it on load.
Specific Commands
/advancement
  • Removed /advancement test in favor of entity selectors.
/blockdata
  • Removed in favor of /data.
/clear
  • The syntax of /clear has changed.
    • /clear [<target>] [<item>] [<data>] [<count>] [<nbt>] will become /clear [<target>] [<item>] [<count>]
    • See the item argument type for more details.
/clone
  • The syntax of /clone has been changed.
    • /clone <begin> <end> <destination> filtered [force|move|normal] [<block>] [<data>] will become /clone <begin> <end> <destination> filtered [<block>] [force|move|normal]
    • /clone <begin> <end> <destination> [replace|masked] [force|move|normal] [<block>] [<data>] will become /clone <begin> <end> <destination> [replace|masked] [force|move|normal]
/defaultgamemode and /gamemode
/difficulty
/effect
  • The syntax of /effect has been split off, to avoid ambiguity.
    • /effect <entity> <effect> is now /effect give <entity> <effect>
    • /effect <entity> clear is now /effect clear <entity> [<effect>]
  • Giving an effect will now fail if it didn't actually do anything.
    • Some mobs are immune (for example an ender dragon).
    • Stronger existing effects prevent new weaker ones.
/enchant
/entitydata
  • Removed in favor of /data.
/execute
  • The syntax of /execute has been split off.
    • Modifier sub-commands can change how the command is run:
      • /execute as <entity> <chained command> executes a command using the entity <entity> (but doesn't change position).
      • /execute at <entity> <chained command> executes a command using the position of <entity> (but doesn't change entity).
      • /execute offset <pos> <chained command> executes a command using the position of <pos>.
      • /execute align <axes> <chained command> executes a command after aligning the current position to the block grid (rounding down), <axes> is any combination of x y and z (for example: x,xz,zyx and yz).
        • Examples:
          • x=-1.8,y=2.3,z=5.9 using x will become x=-2,y=2.3,z=5.9
          • x=2.4,y=-1.1,z=3.8 using yxz will become x=2,y=-2,z=3
    • Conditional sub-commands can let you prevent the command from running at all:
      • /execute (if|unless) block <pos> <block> <chained command> executes a command if (or unless) <pos> matches <block>.
      • /execute (if|unless) blocks <begin> <end> <destination> (all|masked) <chained command> executes a command if (or unless) the region between <start> and <end> matches <destination>.
      • /execute (if|unless) entity <entity> <chained command> executes a command if (or unless) <entity> exists (returns 1 or more entities).
      • /execute (if|unless) score <target> <targetObjective> (<|<=|=|>=|>) <source> <sourceObjective> <chained command> executes a command if (or unless) <target>'s score relates to <source>'s score based on the chosen criterium.
    • As replacement for /stats, a new sub-command store lets you store the result or success of a command somewhere:
      • result is the result of a command, which replaces these old stats: AffectedBlocks, AffectedEntities, AffectedItems, QueryResult.
      • success is how many times the command was successful. This is usually 0 or 1, but if the command split up (for example as @a) then it may be more than 1. This replaces SuccessCount.
      • The value will be stored when the full command has finished executing.
      • If a command isn't successful (success is 0), result will always be set to 0.
      • It will be made clear what the expected result of each command is.
      • /execute store (result|success) score <name> <objective> <chained command>
        • The value is stored into the scoreboard under <name> and <objective>.
        • The objective must exist, but unlike with /stats you don't need to set an initial value for <name>.
      • /execute store (result|success) block <pos> <path> (byte|double|float|int|long|short) <scale> <chained command>
        • The value is stored in the nbt data at path of the block at pos as a byte, double, float, int, long, or short.
      • /execute store (result|success) entity <target> <path> (byte|double|float|int|long|short) <scale> <chained command>
        • The value is stored in the nbt data at path of one target entity as a byte, double, float, int, long, or short.
      • Data paths look like this: foo.bar[0]."A [crazy name]".baz.
        • foo.bar means foo's child called bar.
        • foo[0] means element 0 of foo.
        • "quoted strings" may be used if a name of a key needs to be escaped.
      • Examples:
        • /execute store success score @a foo run say hi
        • /execute as @e[type=pig] at @s store success entity @s Saddle byte 1 if entity @p[distance=..5]
    • You can chain all sub-commands together.
      • After every sub-command you need to write another sub-command.
      • When you're done with chaining sub-commands, run lets you write the actual command to be executed.
        • / is no longer allowed before the command.
      • /execute as somebody at somebody run say hi
    • Example of old commands:
      • /execute @e ~ ~ ~ detect ~ ~ ~ stone 0 say Stone! is now /execute as @e at @s if block ~ ~ ~ stone run say Stone!
      • /execute @e ~ ~ ~ detect ~ ~ ~ grass 0 summon pig is now /execute at @e if block ~ ~ ~ grass run summon pig
      • /execute @e ~ ~ ~ say Hello! is now /execute as @e run say Hello!
/experience
  • /xp is now an alias for /experience.
  • Split up into 3 different subcommands:
    • /experience add <players> <amount> [points|levels]
      • Adds <amount> of either points or levels to the target <players> (defaults to points).
      • Adding points can cause players to level up, as usual.
      • Negative numbers are supported, to subtract points instead.
      • Subtracting points can cause players to level down.
    • /experience set <players> <amount> [points|levels]
      • Sets <amount> of either points or levels on the target <players> (defaults to points).
      • You cannot set more points than their current level allows.
      • When changing levels, the points will stay at the same percentage as the previous level.
    • /experience query <player> (points|levels)
      • Returns either the number of points or levels on the given <player>.
/fill
  • The syntax of /fill has been changed.
    • /fill <begin> <end> <block> <data> replace [<replaceBlock>] [<replaceData>] is now /fill <begin> <end> <block> replace [<filter>]
    • /fill <begin> <end> <block> [<data>] [destroy|hollow|keep|outline|replace] [<nbt>] is now /fill <begin> <end> <block> [destroy|hollow|keep|outline|replace]
/function
  • /function no longer accepts [if|unless] <entity> arguments.
/gamerule
  • /gamerule no longer accepts unknown rules ("custom gamerules").
    • You can use functions or scoreboards as replacements, with no loss of functionality.
    • Existing custom gamerules will just not be accessible. Only built-in rules will be available.
  • Values to /gamerule are now type checked (giving a string if it wants an int is a very obvious error).
  • Removed the gameLoopFunction gamerule in favor of functions tagged in minecraft:tick.
/give
  • The syntax of /give has changed.
    • /give <players> <item> [<count>] [<data>] [<nbt>] is now /give <players> <item> [<count>]
    • See the item argument type for more details.
/kill
  • A target is now mandatory
/locate
  • The y-coordinate is now returned as 64 instead of ?.
  • The result of the command, used by /execute store, will be the absolute distance to the structure.
/particle
  • The <params> argument has been removed, instead the parameters for particles like block can be specified right after the <name> argument using the new block argument.
    • /particle block polished_granite ~ ~ ~ 0 0 0 0 1
/playsound
  • Will Tab ↹ auto-complete custom sound events.
/replaceitem
  • The syntax of /replaceitem has changed.
    • /replaceitem block <pos> <slot> <item> [<count>] [<data>] [<nbt>] is now /replaceitem block <pos> <slot> <item> [<count>]
    • /replaceitem entity <target> <slot> <item> [<count>] [<data>] [<nbt>] is now /replaceitem entity <target> <slot> <item> [<count>]
    • See the item argument type for more details.
  • The slot argument no longer requires slot..
    • For example, slot.hotbar.1 now is hotbar.1
/scoreboard
  • /scoreboard had [<dataTag>] removed from its commands in favor of the nbt argument in entity selectors.
  • /scoreboard players tag and /scoreboard teams removed. Replaced by /tag and /team respectively.
  • /scoreboard players test removed in favor of /execute (if|unless) score, entity selectors and /scoreboard players get <target> <objective>.
/setblock
  • The syntax of /setblock has changed.
    • /setblock <pos> <block> [<data>] [<mode>] [<nbt>] is now /setblock <pos> <block> [<mode>]
    • See the block argument type for more details.
/stats
  • Removed. Now part of /execute.
  • The new /execute one isn't a direct replacement, the behavior has changed:
    • It's now per-command, instead of per-entity or per-block.
    • There's only result and success, which covers all the old stat types.
/stopsound
  • * can now be used instead of source to stop all sounds with a certain name, across all sources.
/tag
  • Replaces /scoreboard players tag.
  • Keeps the same syntax.
    • /tag <players> add <tag> to add <tag> to <players>.
    • /tag <players> remove <tag> to remove <tag> from <players>.
    • /tag <players> list to list all tags on players.
/team
  • Replaces /scoreboard teams.
  • Keeps the same syntax.
    • /team add <team> [<displayname>]
    • /team empty <team>
    • /team join <team> [<members>]
    • /team leave [<members>]
    • /team list [<team>]
    • /team option <team> <option> <value>
/testfor, /testforblock and /testforblocks
/toggledownfall
  • Removed. It was always used to stop the rain, then make you frustrated in a minute when it's raining again.
  • Use /weather.
/tp and /teleport
  • /tp is now an alias of /teleport (much like /w, /msg and /tell).
  • Coordinates are now relative to the executor, as with all other commands.
  • The syntax of /tp remains, but with the behavior of /teleport.
/trigger
  • /trigger <objective> is a new syntax as a shortcut for /trigger <objective> add 1.
/weather
  • If you don't specify a time, it now defaults to 5 minutes (previously random).
Argument Types
Target selectors
  • More error handling has been introduced.
  • Arguments may now be quoted.
    • Things like limit=0, level=-10, gamemode=purple are not allowed.
  • There's no longer a "min" and "max" separate values, we instead support ranges.
    • level=10 is level 10
    • level=10..12 is level 10, 11 or 12
    • level=5.. is anything level 5 or above
    • level=..15 is anything level 15 or below
  • The arcane shorthand names have been renamed.
    • m -> gamemode
    • l or lm -> level
    • r or rm -> distance
    • rx or rxm -> x_rotation
    • ry or rym -> y_rotation
    • c -> limit
  • x, y, z, distance, x_rotation, y_rotation are now doubles and allow values like 12.34
    • x and z are no longer center-corrected.
      • This means x=0 no longer equates to x=0.5.
  • gamemode (previously m) no longer allows numerical or shorthand IDs.
  • limit (was c) No longer allows negative values.
    • Use sort=furthest instead.
  • The name argument now supports spaces (as long as it's quoted).
  • Multiple of the same argument in target selectors is now possible.
    • tag=foo,tag=bar,tag=!baz matches someone with foo, bar and not baz.
    • type=!cow,type=!chicken matches something that isn't a cow and isn't a chicken.
    • type=cow,type=chicken isn't allowed, because something cannot both be a cow and chicken.
  • You can specify the sorting.
    • sort=nearest is the old default, sorting by distance (default for @p)
    • sort=furthest is the reverse of that (previously you'd use c=-5 for this)
    • sort=random for random sorting (default for @r)
    • sort=arbitrary is a new option to not sort the result (default for @e, @a)
  • Specifying scores now looks like scores={foo=1,bar=1..5}
  • You can test for advancements with advancements={foo=true,bar=false,custom:something={criterion=true}}
    • true for "they completed the advancement", false for "they have not completed the advancement"
    • Alternatively, pass a block of specific criteria to test for (again, true/false)
Blocks
  • Wherever a <block>, optionally [<data>] and optionally [<nbt>] was required, it's now a single <block> argument that looks like this:
    • stone
    • minecraft:redstone_wire[power=15,north=up,south=side]
    • minecraft:jukebox{RecordItem:{...}}
    • minecraft:furnace[facing=north]{BurnTime:200}
  • ID is required (though just as before, if namespace isn't set it defaults to minecraft:).
  • States are inside [], comma-separated and must be properties/values supported by the blocks. They are optional.
    • minecraft:stone[doesntexist=purpleberry] is a syntax error, because stone doesn't have doesntexist.
    • minecraft:redstone_wire[power=tuesday] is a syntax error, because redstone_wire's power is a number between 0 and 15.
  • NBT tag is inside {}, and works just like you'd expect. It's optional.
  • In the context of "conditions"/testing for blocks, only the states you provided will be tested.
    • If you test redstone_wire[power=15], it only checks power but ignores other states such as north.
  • In the context of setting blocks, any states you provided will be set but anything missed out will default depending on the block.
    • If you set redstone_wire[power=15], it will set power to 15 but north will be a default value (in this case, set to none).
  • There is no such thing as block data value in 1.13. It's either a different blocks, or a state.
Items
  • Wherever an <item>, optionally [<data>] and optionally [<nbt>] was required, it's now a single <item> argument that looks like this:
    • stone
    • minecraft:stick{display:{Name:"Stick of Untruths"}}
  • ID is required (though just as before, if namespace isn't set it defaults to minecraft:).
  • NBT tag is inside {}, and works just like you'd expect. It's optional.
  • There is no such thing as item data value or item damage value in 1.13.
    • Damage, where applicable, is being moved into nbt.
    • Any other information is either a separate item or a property in nbt.

Mobs

Horse 17w46a.png
Horse
  • The model has been changed to be more consistent with other mobs[3]
  • Some animations like opening its mouth when grazing have been removed from the model as well.

Structures

Witch Huts
  • Now generates with a mushroom in the flower pot.
    • Previously, it was completely empty.

Other

Controls
  • The name of keybindings now describes the actual key (e.g. 'LBUTTON' -> 'Left Button', 'BACKSLASH' -> '\')
Options
  • Removed 3D Anaglyph completely
Resource packs
  • Updated format number
  • The default resource pack can now be moved up and down on the resource pack selection screen.
