Java Edition 1.13

1.13, the first release of the Update Aquatic, is an upcoming major update set to be released in Q2 2018. It will focus mainly on ocean content, bug fixes, technical features, and optimization.

General

 * Data packs
 * Like resource packs, but for loot tables, advancements, functions, structures, recipes and tags.
 * Used by placing them into the  folder of a world.
 * Data packs are  files or folders, with a   in the root. See: Tutorials/Creating a resource pack. The packs are located in.
 * Structures will load from  before checking data packs.
 * However, this directory should not be used to distribute structures. Instead, move these files into data packs.
 * Reloadable using.
 * Structure:,   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,  ,  ,  ,   and.


 * 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  will run every tick at the beginning of the tick.
 * Functions tagged in  will run once after a (re)load.
 * Tags are created using data packs in,  , and.
 * 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  to your tag definition will make the tag overwrite instead.
 * For example:
 * This will create a block tag called.
 * 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  in a tag value list to reference another tag called.
 * Self referencing is not possible.
 * There are 10 default tags for both items and blocks:,  ,  ,  ,  ,  ,  ,  ,   and
 * There are 3 extra default tags for blocks that don't have an equivalent for items:,  , and.
 * Advancement item predicates now support item s.


 * Loot tables
 * Added the  function to loot tables.


 * Death Messages
 * Added a 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.
 * Added a death message for when a mob or player causes another player to die in the void.
 * "Player didn't want to live in the same world as Player/Mob"


 * 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.

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  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 execution rotation, defaulting to  (south).
 * Like world coordinates, they are by default measured from the base of an entity.
 * The syntax is:
 * is the amount of blocks in the specified direction.


 * Specific commands
 * A command that allows the player to get, merge, and remove entity and block nbt data
 * Will return the NBT data from the block at . A   can be specified to only retrieve that nbt data. Numeric values will be set as the   of the command, strings will set set the length of the string as the , lists will set the number of elements in the list as the  , and compounds will set the number of tags that are directly in that compound as the  . An optional   can be provided to scale the number retrieved.
 * Will return the NBT data from one  entity. A   can be specified to only retrieve that nbt data. Numeric values will be set as the   of the command, strings will set set the length of the string as the , lists will set the number of elements in the list as the  , and compounds will set the number of tags that are directly in that compound as the  . An optional   can be provided to scale the number retrieved.
 * Will merge the block nbt data at  with the specified   data.
 * Will merge the entity nbt data from  with the specified   data. Merging player nbt data is not allowed.
 * Will remove nbt data at  from the block at.
 * Will remove nbt data at  from one   entity. Removing player nbt data is not allowed.
 * Data paths look like this:.
 * means foo's child called bar.
 * means element 0 of foo.
 * "quoted strings" may be used if a name of a key needs to be escaped.
 * Examples of old commands:
 * is now
 * is now
 * Examples of new functionalities:
 * means foo's child called bar.
 * means element 0 of foo.
 * "quoted strings" may be used if a name of a key needs to be escaped.
 * Examples of old commands:
 * is now
 * is now
 * Examples of new functionalities:


 * A command to control loaded data packs.
 * Has the following subcommands:
 * - will enable the specific pack.
 * - will disable the specific pack.
 * - 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:
 * - will enable the specific pack, putting it in its default position.
 * - will enable the specific pack, putting it before any other pack (lowest priority)
 * - will enable the specific pack, putting it after any other pack (highest priority)
 * - will enable the specific pack, putting it before (lower priority) pack
 * - will enable the specific pack, putting it after (higher priority) pack
 * - will enable the specific pack, putting it after (higher priority) pack


 * Added.
 * Will rotate an entity to face either an entity or a location.
 * Will rotate an entity to face either an entity or a location.

 * Added  and   to.
 * Added  and   to.

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.

Items

 * An item form for bark blocks for all six types of wood.
 * 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.
 * A model for petrified oak slab - the old wood slab that acts like a stone slab.

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  instead of
 * Damage has been moved to the  tag and is only used by tools and armor; maps use a   tag.
 * Files and commands no longer use  or.
 * 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 can now be loaded from data packs in


 * Creative Inventory
 * Because of The "flattening", certain blocks and items have been moved around in their respective groups, for example the Purpur block is now after Obsidian.
 * Mushroom Blocks, farmland and grass path are added to the inventory, under the Decoration Blocks group. Additionally, blank firework rockets are added to the Miscellaneous group.


 * Statistics
 * Statistics are being updated.
 * is now.
 * is now.


 * Other
 * Game library updates
 * Upgraded to LWJGL 3
 * Loading or creating a world shows the percentages of the loading stages.
 * now shows as a loading stage.
 * Crash reports now list what data packs are enabled.
 * Data generators are now exposed, you can get a dump of all blocks/items/commands/etc from the game without opening it up.
 * Changed translation files from  to.
 * Now supports newlines.

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:
 * The output signal of a command block used to be its "success count", but now is its "result".
 * Changed all custom names (blocks, items, entities, block entities) to translatable text components.
 * Server commands (functions, console, rcon) now run from world spawn in the overworld, instead of at.
 * Errors during a command are now a nicer error message (with a tool tip for more info).
 * Added commands to the profiler (/debug).


 * NBT
 * and  nbt keys of item entities are no longer strings but are instead compounds with two longs named   and.
 * nbt keys of snowballs, eggs and ender pearls are no longer strings but are instead compounds with two longs named  and.


 * 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


 * Removed in favor of entity selectors.
 * Removed in favor of entity selectors.


 * Removed in favor of.
 * Removed in favor of.


 * The syntax of has changed.
 * {{cmd|clear [ ] [ ] [ (but doesn't change position).
 * {{cmd|execute at }} executes a command using the position, rotation, and dimension of the   (but doesn't change entity).
 * {{cmd|execute positioned }} executes a command using the position of.
 * {{cmd|execute positioned as }} executes a command using the position (x y z) of the   but nothing else.
 * {{cmd|execute align }} executes a command after aligning the current position to the block grid (rounding down),   is any combination of     and   (for example: , ,  and  ).
 * Examples:
 * using  will become
 * using  will become
 * {{cmd|execute facing }} executes a command as though the executor is facing.
 * {{cmd|execute facing entity (eyes{{!}}feet) }} executes a command as though the executor is facing the entity's eyes or feet.
 * {{cmd|execute rotated as }} executes a command as though the executor is rotated in the direction of the entity.
 * {{cmd|execute rotated }} will run the command as though the executor is rotated in the specified direction.
 * {{cmd|execute in (overworld{{!}}the_end{{!}}the_nether) }} executes a command as though the executor is in the specified dimension.
 * {{cmd|execute anchored (feet{{!}}eyes) }} will make the rest of this command use feet or eyes for ^ ^ ^ coordinates or facing commands.
 * Conditional sub-commands can let you prevent the command from running at all:
 * {{cmd|execute (if{{!}}unless) block  }} executes a command if (or unless)   matches.
 * {{cmd|execute (if{{!}}unless) blocks  (all{{!}}masked) }} executes a command if (or unless) the region between   and   matches.
 * {{cmd|execute (if{{!}}unless) entity }} executes a command if (or unless)   exists (returns 1 or more entities).
 * {{cmd|execute (if{{!}}unless) score  ( < {{!}} <= {{!}} = {{!}} >= {{!}} > ) 's score relates to  's score based on the chosen criterium.
 * {{cmd|execute (if{{!}}unless) score matches  }} executes a command if (or unless)  's score is in the   (ie ,  ).
 * As replacement for {{cmd|stats}}, a new sub-command  lets you store the result or success of a command somewhere:
 * is the result of a command, which replaces these old stats:,  ,  ,.
 * is how many times the command was successful. This is usually  or , but if the command split up (for example  ) then it may be more than  . This replaces.
 * The value will be stored when the full command has finished executing.
 * If a command isn't successful ( is  ),   will always be set to.
 * It will be made clear what the expected result of each command is.
 * {{cmd|execute store (result{{!}}success) score  }}
 * The value is stored into the scoreboard under  and.
 * The  must exist, but unlike with {{cmd|stats}} you don't need to set an initial value for.
 * {{cmd|execute store (result{{!}}success) block (byte{{!}}double{{!}}float{{!}}int{{!}}long{{!}}short)  }}
 * The value is stored in the nbt data at  of the block at   as a byte, double, float, int, long, or short.
 * {{cmd|execute store (result{{!}}success) entity (byte{{!}}double{{!}}float{{!}}int{{!}}long{{!}}short)  }}
 * The value is stored in the nbt data at  of one   entity as a byte, double, float, int, long, or short.
 * Like, {{cmd|execute store}} can't modify player nbt. Nbt inside the  key of items in the player's   or   is an exception and can be modified by {{cmd|execute store}}.
 * Data paths look like this:.
 * means foo's child called bar.
 * means element 0 of foo.
 * "quoted strings" may be used if a name of a key needs to be escaped.
 * Examples:
 * {{cmd|execute store success score @a foo run say hi}}
 * {{cmd|/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,  lets you write the actual command to be executed.
 * is no longer allowed before the command.
 * {{cmd|execute as somebody at somebody run say hi}}
 * Example of old commands:
 * {{cmd|execute @e ~ ~ ~ detect ~ ~ ~ stone 0 say Stone!}} is now {{cmd|execute as @e at @s if block ~ ~ ~ stone run say Stone!}}
 * {{cmd|execute @e ~ ~ ~ detect ~ ~ ~ grass 0 summon pig}} is now {{cmd|execute at @e if block ~ ~ ~ grass_block run summon pig}}
 * {{cmd|execute @e ~ ~ ~ say Hello!}} is now {{cmd|execute as @e run say Hello!}}
 * {{cmd|execute @e ~ ~ ~ say Hello!}} is now {{cmd|execute as @e run say Hello!}}


 * {{cmd|experience}}
 * {{cmd|xp}} is now an alias for {{cmd|experience}}.
 * Split up into 3 different subcommands:
 * {{cmd|experience add [points{{!}}levels]}}

 * 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.
 * {{cmd|experience set [points{{!}}levels]}}
 * Sets  of either points or levels on the target   (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.
 * {{cmd|experience query (points{{!}}levels)}}
 * Returns either the number of points or levels on the given.


 * {{cmd|fill}}
 * The syntax of {{cmd|fill}} has been changed.
 * {{cmd|fill    arguments.
 * This has been moved into {{cmd|execute}}.
 * {{cmd|function foo if @e}} is now {{cmd|execute if entity @e run function foo}}


 * {{cmd|gamerule}}
 * {{cmd|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 {{cmd|gamerule}} are now type checked (giving a string if it wants an int is a very obvious error).
 * Removed the  gamerule in favor of functions tagged in.


 * {{cmd|give}}
 * The syntax of {{cmd|give}} has changed.
 * {{cmd|give [ ] [  is now mandatory


 * {{cmd|locate}}
 * The y-coordinate is now returned as  instead of.
 * The  of the command, used by {{cmd|execute store}}, will be the absolute distance to the structure.


 * {{cmd|particle}}

 * {{cmd|particle block polished_granite ~ ~ ~ 0 0 0 0 1 }}
 * {{cmd|particle dust 1 1 1 1 ~ ~ ~ 0 0 0 0 1 }}
 * are, in order, the three RGB color values (0-1) and the size of the particle.

 * {{cmd|tp}} and {{cmd|teleport}}
 * {{cmd|tp}} is now an alias of {{cmd|teleport}} (much like {{cmd|w}}, {{cmd|msg}} and {{cmd|tell}}).
 * {{cmd|teleport}} has been simplified a bit, to avoid ambiguity.
 * {{cmd|teleport }} doesn't allow rotation or facing, will teleport you to the entity.

 * ,,  ,  ,  ,   are now doubles and allow values like
 * and  are no longer center-corrected.
 * This means  no longer equates to.
 * (previously ) no longer allows numerical or shorthand IDs.
 * (was ) No longer allows negative values.
 * Use  instead.
 * The  argument now supports spaces (as long as it's quoted).
 * Multiple of the same argument in target selectors is now possible.
 * matches someone with,   and not.
 * matches something that isn't a cow and isn't a chicken.
 * isn't allowed, because something cannot both be a cow and chicken.
 * You can specify the sorting.
 * is the old default, sorting by distance (default for )
 * is the reverse of that (previously you'd use  for this)
 * for random sorting (default for )
 * is a new option to not sort the result (default for,  )
 * Specifying scores now looks like
 * You can test for advancements with
 * for "they completed the advancement",  for "they have not completed the advancement"
 * Alternatively, pass a block of specific criteria to test for (again, / )
 * for "they completed the advancement",  for "they have not completed the advancement"
 * Alternatively, pass a block of specific criteria to test for (again, / )


 * Blocks
 * Wherever a, optionally   and optionally   was required, it's now a single   argument that looks like this:
 * ID is required (though just as before, if namespace isn't set it defaults to ).
 * States are inside, comma-separated and must be properties/values supported by the blocks. They are optional.
 * is a syntax error, because  doesn't have.
 * is a syntax error, because 's   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, it only checks power but ignores other states such as.
 * 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, it will set   to 15 but   will be a default value (in this case, set to  ).
 * There is no such thing as block data value in 1.13. It's either a different blocks, or a state.
 * Items
 * Wherever an, optionally   and optionally   was required, it's now a single   argument that looks like this:
 * ID is required (though just as before, if namespace isn't set it defaults to ).
