Java Edition 1.13/Development versions

This is a list of Java Edition 1.13 development versions.

17w43a

17w43a is the first snapshot for Java Edition 1.13, released on October 25, 2017^[1], adding the first features of what was then called "Technically Updated". Although this is the first snapshot of 1.13, no Update Aquatic features were implemented yet because at the time the Update Aquatic was set to be released as 1.14 instead of 1.13, and as such snapshots from 17w43a to 18w06a mainly add or modify commands.

Additions

General

Data packs

• Like resource packs, but for loot tables, advancements, functions, and structures.
  • 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 for more info.
• 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 and structures.

Options

• Fullscreen resolution
  • Is used to change the resolution when in fullscreen.

Changes

General

Controls

• The name of keybindings now describes the actual key (e.g. 'LBUTTON' is changed to 'Left Button' and 'BACKSLASH' is changed to '\').

Missing texture

• Changed from to , shifting the positions of each constituent square.

Options

• Removed 3D Anaglyph completely.

Other

• Game library updates
  • Upgraded to LWJGL 3.1.2
• Loading or creating a world shows the percentages of the loading stages.
  • Preparing spawn area now shows as a loading stage.

Resource packs

• The default resource pack can now be moved up and down, just like other resource packs.
• Something has changed about loading resources - it appears as though all textures are preloaded in 1.12.2, but not necessarily from this snapshot onward.

Additions

Command format

General

• A command UI when typing commands in the chat.
  • Different components of commands are displayed in different colors.
  • Errors are displayed in red without having to run the command.
• An nbt argument in target selectors.
• A new command parsing library called Brigadier.

Changes

Mobs

Horses

• The model has been simplified to be more consistent with other mobs.
• Some animations like opening its mouth when grazing has been removed from the model as well, and the saddle animation is changed slightly.

Command format

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".

Block argument type

• Wherever a <block>, optionally [<data>] and optionally [<nbt>] was required, it is 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 does not have doesntexist.
  • minecraft:redstone_wire[power=tuesday] is a syntax error, because redstone_wire's power is a number between 0 and 15.
• An optional tag is inside {}, and works just like the player would expect.
• In the context of "conditions"/testing for blocks, only the states the player provided are tested.
  • If the player tests redstone_wire[power=15], it only checks power but ignores other states such as north.
• In the context of setting blocks, any states the player provided are set but anything missed out defaults depending on the block.
  • If the player set redstone_wire[power=15], it sets power to 15 but north is a default value (in this case, set to none).
• There is no such thing as block data value in 1.13, but either a different block or a state.

Commands

/?

• Removed in favor of /help.

/advancement

• Removed /advancement test in favor of entity selectors.

/clear

• The syntax of /clear has changed.
  • /clear [<target>] [<item>] [<data>] [<count>] [<nbt>] becomes /clear [<target>] [<item>] [<count>].
  • See the item argument type for more details.
  • [<data>] has been removed in preparation for the flattening, item data is no longer a thing and item damage values are moved into NBT.

/clone

• The syntax of /clone has been changed.
  • /clone <begin> <end> <destination> filtered [force|move|normal] [<block>] [<data>] becomes /clone <begin> <end> <destination> filtered [<block>] [force|move|normal].
  • /clone <begin> <end> <destination> [replace|masked] [force|move|normal] [<block>] [<data>] becomes /clone <begin> <end> <destination> [replace|masked] [force|move|normal].

/defaultgamemode and /gamemode

• Now only accepts string IDs, not shorthand or numeric.
  • /gamemode 2 becomes /gamemode adventure.
  • /defaultgamemode sp is now /defaultgamemode spectator.

/difficulty

• /difficulty [<value>] now only accepts string IDs, not shorthand or numeric.
  • /difficulty 2 is now /difficulty normal.
  • /difficulty p is now /difficulty peaceful.
• The player can now query for the current difficulty by using /difficulty without any arguments.

/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 now fails if it didn't actually do anything.
  • Some mobs are immune (for example an ender dragon).
  • Stronger existing effects prevent new weaker ones.

/enchant

• Removed from the game, in order to be replaced by the planned /modifyitem command (later reverted in 18w06a).

/execute

• The syntax of /execute has been split off.
  • Modifier sub-commands can change how the command is ran:
    • /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 becomes x=-2,y=2.3,z=5.9.
        • x=2.4,y=-1.1,z=3.8 using yxz becomes x=2,y=-2,z=3.
  • Conditional sub-commands can let the player 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 criterion.
  • As replacement for /stats, a new sub-command store lets the player store the result or success of a command somewhere:
    • /execute store (result|success) <name> <objective> <chained command>.
    • 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 is stored into the scoreboard under <name> and <objective>.
    • The objective must exist, but unlike with /stats, the player doesn't need to set an initial value for <name>.
    • The value is stored when the full command has finished executing.
    • If a command isn't successful (success is 0), result is always set to 0.
    • It is made clear what the expected result of each command is.
  • The player can chain all sub-commands together.
    • After every sub-command, the player needs to write another sub-command.
    • When the player is done with chaining sub-commands, run lets players 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).
    • The player cannot set more points than their current level allows.
    • When changing levels, the points 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 <x y z> <xt yt zt> <block> <data> replace [<replaceBlock>] [<replaceData>] is now /fill <x y z> <xt yt zt> <block> replace [<filter>].
  • /fill <x y z> <xt yt zt> <block> [<data>] [destroy|hollow|keep|outline|replace] [<nbt>] is now /fill <x y z> <xt yt zt> <block> [destroy|hollow|keep|outline|replace].

/function

• /function no longer accepts [if|unless] <entity> arguments.
  • This has been moved into /execute.
  • /function foo if @e is now /execute if entity @e run function foo.

/gamerule

• /gamerule no longer accepts unknown rules ("custom gamerules").
  • The player can use functions or scoreboards as replacements, with no loss of functionality.
  • Existing custom gamerules are not accessible. Only built-in rules are available.
• Values to /gamerule are now type checked (giving a string if it wants an int is a very obvious error).

/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.
  • [<data>] has been removed in preparation for the flattening, item data is no longer a thing and item damage values are moved into NBT.

/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, is the absolute distance to the structure.

/op

• Now allows target selectors besides names.

/particle

• The <params> argument has been removed, instead the parameters for particles like blockcrack can be specified right after the <name> argument using the new block argument.
  • /particle blockcrack stone [variant=smooth_granite] ~ ~ ~ 0 0 0 0 1.
• The particle names have been converted to lowercase and optionally have a namespace.

/publish

• Added an optional port argument.

/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.
  • [<data>] has been removed in preparation for the flattening, item data is no longer a thing and item damage values are moved into NBT.
• 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 changes above for more details.

/stats

• Removed. Now part of /execute.
• The new /execute one is not a direct replacement, the behavior has changed:
  • It is 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>.

  • /team leave [<members>]
  • /team list [<team>]
  • /team option <team> <option> <value>

/testfor, /testforblock and /testforblocks

• Removed and now part of /execute.

/toggledownfall

• Removed in favor of /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 the player doesn't specify a time, it now defaults to 5 minutes (previously random).

Items

• Wherever an <item>, optionally [<data>] and optionally [<nbt>] was required, it is 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:).
• An optional tag is inside {}, and works just like the player would expect.
  • Any other information is either a separate item or a property in NBT.

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 is 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.
• The player can specify the sorting.
  • sort=nearest is the old default, sorting by distance (default for @p).
  • sort=furthest is the reverse of that (previously the player would 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}.
• The player 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).

  • /data get block <pos> [<path>] [<scale>]
    • Returns 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>]
    • Returns 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>
    • Merges the block NBT data at <pos> with the specified <nbt> data.
  • /data merge entity <target> <nbt>

17w49a

17w49a is the ninth snapshot for Java Edition 1.13, released on December 6, 2017^[11], which added block and item tags.

Additions

General

Tags

• Items and blocks can now 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.
• Tags are created using data packs in data/(namespace)/tags/blocks or data/(namespace)/tags/items.
  • For example: data/(namespace)/tags/blocks/foo.json.
  • This creates a block tag called (namespace):foo.
  • The json file contains a list of all blocks that should be "tagged".
• There are two default tags for both the item form and the block form: minecraft:wool for all wool blocks and minecraft:planks for all wood plank blocks.

Changes

General

Crafting

• Recipes can now refer to a tag instead of an item.

Command format

/teleport

• Has been simplified:
  • /teleport <entity> does not allow rotation or facing, and teleports to the entity.
  • /teleport <x y z> does not allow rotation or facing, and teleports to the position.
  • /teleport <entity1> <entity2> does not allow rotation or facing, and teleports entity1 to entity2.
  • /teleport <entity> <x y z> [<yRot> <xRot>] teleports <entity> to that position with optional rotation.
  • /teleport <entity> <x y z> facing [<xFacing> <yFacing> <zFacing>] teleports <entity> to that position facing another position.

/execute

• Added new sub-commands to /execute to allow for more control over commands.
  • facing <x y z> runs the command as though the executor is facing x y z.

  • at <entity> changes the dimension, position and rotation of the command to match that entity.
  • (if|unless) score <name> <objective> matches <range> tests for a score in a range (ie 1, 1..5).
