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
- FS (Fullscreen) Resolution
- Is used to change the resolution.
- Like resource packs, but for loot tables, advancements, functions, and structures.
- Can be changed from world to server side.
- Used by placing them into the world or server file, and it is also possible to use multiple data packs, or none at all
- Data packs are
.zipfiles or folders with apack.mcmetain 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).nbtbefore 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,datafolder containing a namespace folder determining the namespace of its contents- A namespace should only contain the following symbols:
0123456789abcdefghijklmnopqrstuvwxyz-_ - Inside the namespace folder, there can be folders for
functions,loot_tables,advancementsandstructures.
- A namespace should only contain the following symbols:
Changes
- General
- Game library updates
- Upgraded to LWJGL 3
- Loading or creating a world shows the percentages of the loading stages.
Preparing spawn areanow shows as a loading stage.
- Removed 3D Anaglyph completely
- The name of keybindings now describes the actual key (e.g. 'LBUTTON' -> 'Left Button', 'BACKSLASH' -> '\')
- The default resource pack can now be moved up and down on the resource pack selection screen.
Planned additions
Commands
- A command UI when typing commands in the chat.[3][4][5][6]
- An
nbtargument in target selectors.[5][6] - New gamerule:
structureSaveDestination.[9] - New command parsing library known as brigadier[10][11]
Planned changes
General
- Block metadata
- Functions will be completely parsed and cached on load.[17]
- This means if a command is incorrect for any reason, the player will know about it on load.
- The damage value parameter in
/give,/clearand/replaceitemwill be removed.[18] - Blocks currently separated by variant, type, and color block states will be split into their own ids. (for example
wool color=redwill becomered_wool.)[18] - Removing the block entity for flower pots, mob heads (except player heads) and note blocks.[18]
Commands
- General[17]
- Commands and functions will be 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 ...
- For example, this is no longer allowed:
- The output signal of a command block used to be its "success count", but now will be its "result".
- Specific Commands[17]
- The syntax of
/clearhas changed.
- The syntax of
/clonehas been changed./clone <x1 y1 z1> <x2 y2 z2> <xt yt zt> filtered [force|move|normal] [<block>] [<data>]will become/clone <x1 y1 z1> <x2 y2 z2> <xt yt zt> filtered [<block>] [force|move|normal]/clone <x1 y1 z1> <x2 y2 z2> <xt yt zt> [replace|masked] [force|move|normal] [<block>] [<data>]will become/clone <x1 y1 z1> <x2 y2 z2> <xt yt zt> [replace|masked] [force|move|normal]
/defaultgamemodeand/gamemode
- Now only accepts string IDs, not shorthand or numeric.
/gamemode 2will become/gamemode adventure/defaultgamemode spwill become/defaultgamemode spectator
/difficultynow only accepts string IDs, not shorthand or numeric./difficulty 2will become/difficulty normal/difficulty pwill become/difficulty peaceful
- The syntax of
/effecthas been split off, to avoid ambiguity.
- The syntax of
/executehas been split off.- Modifier sub-commands can change how the command is ran:
/execute as <entity> <chained command>executes acommandusing the entity<entity>(but doesn't change position)./execute at <entity> <chained command>executes acommandusing the position of<entity>(but doesn't change entity)./execute offset <x y z> <chained command>executes a command using the position of<x y z>.
- Conditional sub-commands can let you prevent the command from running at all:
/execute (if|unless) block <x y z> <block> <chained command>executes acommandif (or unless)<x y z>matches<block>./execute (if|unless) blocks <begin> <end> <destination> (all|masked) <chained command>executes acommandif (or unless) the region between<start>and<end>matches<destination>./execute (if|unless) entity <entity> <chained command>executes acommandif (or unless)<entity>exists (returns 1 or more entities).
- As replacement for
/stats, a new sub-commandstorelets you store the result of a command somewhere:/execute store (result|success) <name> <objective> <chained command>resultis the result of a command, which replaces these old stats:AffectedBlocks,AffectedEntities,AffectedItems,QueryResult.successis how many times the command was successful. This is usually0or1, but if the command split up (for exampleas @a) then it may be more than1. This replacesSuccessCount.- The value is stored into the scoreboard under
<name>and<objective>. - The
objectivemust exist, but unlike with/statsyou don't need to set an initial value for<name>. - The value will be stored when the full command has finished executing.
- If a command isn't successful (
successis0),resultwill always be set to0. - It will be made clear what the expected result of each command is.
- 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,
thenlets you write the actual command to be executed. /execute as somebody at somebody then say hi
- Example of old commands:
/execute @e ~ ~ ~ detect ~ ~ ~ stone 0 say Stone!will become/execute as @e at @s if block ~ ~ ~ stone then say Stone!/execute @e ~ ~ ~ detect ~ ~ ~ grass 0 summon pigwill become/execute at @e if block ~ ~ ~ grass then summon pig/execute @e ~ ~ ~ say Hello!will become/execute as @e then say Hello!
- Modifier sub-commands can change how the command is ran:
/xpis 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.
- Adds
/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.
- Sets
/experience query <player> (points|levels)- Returns either the number of points or levels on the given
<player>.
- Returns either the number of points or levels on the given
/fill
- The syntax of
/fill has been changed.
/fill <x y z> <xt yt zt> <block> <data> replace [<replaceBlock>] [<replaceData>] will become /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>] will become /fill <x y z> <xt yt zt> <block> [destroy|hollow|keep|outline|replace]
/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).
/give
- Now Tab ↹ auto-completes custom sound events[11]
- The syntax of
/replaceitem has changed.
/replaceitem block <pos> <slot> <item> [<count>] [<data>] [<nbt>] will become /replaceitem block <pos> <slot> <item> [<count>]
/replaceitem entity <target> <slot> <item> [<count>] [<data>] [<nbt>] will become /replaceitem entity <target> <slot> <item> [<count>]
- See the item argument type for more details.
/scoreboard had [<dataTag>] removed from its commands, as they're no longer needed.
/testfor, /testforblock and /testforblocks
- Removed. Now part of
/execute.
- Removed. It was always used to stop the rain, then make you frustrated in a minute when it's raining again.
- Use
/weather.
- Argument Types[17]
- More error handling has been introduced.
- 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).[19]
- Multiple of the same argument in target selectors is now possible.[20]
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 default and current behaviour (except for @r).
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, which is useful if you're optimising commands and don't need sorting.
- 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.[18]
- 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.[18]
- Damage, where applicable, is being moved into nbt.
- Any other information is either a separate item or a property in nbt.
Mobs
- The model will be changed to be more consistent with other mobs[21]
Unconfirmed features
These features are not confirmed for 1.13, but they were mentioned or showcased by developers during development. Main article: Mentioned features- The ability to change biome dependent colors (such as foliage, water, and the sky) without needing mods.[22]

- Ability for the recipe book to show smelting recipes.[25]
- Customizable furnace recipe files. [26]
- Suggesting tab-completions will be added at command input.[27]
- Recipe book design might be changed.[28][29]
- A new command:
/modifyitem[30]
/save-all, /save-on and /save-off will be replaced by /save, /save enable and /save disable.[31]
/ban, /ban-ip, /pardon and /pardon-ip will be replaced by other commands.[32]
- The
/particle command will be changed.[33]
