Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.1Newest
Minecraft 1.21
Minecraft 1.20.3–1.20.4
Minecraft 1.20–1.20.1

⬇ Download for 1.21.1 ⬇ Download for 1.21 ⬇ Download for 1.20.3–1.20.4 ⬇ Download for 1.20–1.20.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Syntax of the command fits right into Vanilla syntax. see Commands/data on Minecraft Wiki

/data modify (block / entity / storage) <path> (set / insert / ...) concat (block / entity / storage) <path> [<separator>]

Squished tree: of /data command
`/data` `… get (block <targetPos>\|entity <target>\|storage <target> \| storageplayer <player>) [<path>] [<scale>]` `… merge (block <targetPos>\|entity <target>\|storage <target> \| storageplayer <player>) <nbt>` `… modify (block <targetPos>\|entity <target>\|storage <target> \| storageplayer <player>) <targetPath> (append\|insert <index>\|merge\|prepend\|set)` `… from (block <sourcePos>\|entity <source>\|storage <source>) [<sourcePath>]` `… concat (block <sourcePos>\|entity <source>\|storage <source>) [<sourcePath>]` `… string (block <sourcePos>\|entity <source>\|storage <source>) [<sourcePath>] [<start>] [<end>]` `… value <value>` `… modify (block <targetPos>\|entity <target>\|storage <target> \| storageplayer <player>)` operation (=, +=, -=, *=, /=, %=, ^=, <, >) <double value> `… remove (block <targetPos>\|entity <target>\|storage <target> \| storageplayer <player>) <path>`

Squished tree: of /data command

/data

… get (block <targetPos>|entity <target>|storage <target> | storageplayer <player>) [<path>] [<scale>]
… merge (block <targetPos>|entity <target>|storage <target> | storageplayer <player>) <nbt>
… modify (block <targetPos>|entity <target>|storage <target> | storageplayer <player>) <targetPath> (append|insert <index>|merge|prepend|set)

Squished tree: of /Loot command
`/loot <TARGET> <SOURCE>` `<TARGET> is:` `block chest` give \| insert \| spawn \| replace <targetPos> insert entity <to entity> inventory <from entity> `<SOURCE>` is: fish \| loot \| kill \| mine inventory <entity> [MaxSlots] <target entity> is of type: player, cart, boat, villager, horse/donkey/llama, item, other living entity `[MaxSlots]` is optional and will return up to n Slots (counting from 1), minus will return last n Slots

Squished tree: of /Loot command

/loot <TARGET> <SOURCE>

<TARGET> is:

block chest
give | insert | spawn | replace <targetPos>
insert entity <to entity> inventory <from entity>

<SOURCE> is:

fish | loot | kill | mine
inventory <entity> [MaxSlots]

<target entity> is of type: player, cart, boat, villager, horse/donkey/llama, item, other living entity

[MaxSlots] is optional and will return up to n Slots (counting from 1), minus will return last n Slots

Concatenate

String + String
List of Strings
Any Array
Multiple Nbt Values (selected by nbt selector)
Nbt Compound (only the top layer) as strings with escaped Quotes ("key":"value")
Return result: amount of elements concatenated

given path will be replaced with new string
p.s. if given path is a string and a string is concatenated, the result is concatenation of those two strings

Math Operation

performs math operation on the target value, target can be of any numeric type, Error will be thrown and success set to 0 when type is not numeric
^= stands for Power, can also be used to calculate root
Targeted Path number TYPE will not change
there might be some precision loss due to Float and Double Math

Storageplayer

store data per player in their own file in /players/<UUID>_pds.dat
works only on players
! Data stored in storageplayer will not be synced with clients, it's purely server side !

Loot ... inventory ...

loot enitiy's inventory into container (works with players, minecarts, boats, merchants, horses, items, and all living entities)
inserting into double chests is now possible (1up over regular loot command) ... /execute as @e[type=item] run loot insert ~ ~-0.1 ~ inventory @s (will try to insert a copy of all dropped items from the world into inventory under your feet)
