Data Command Plus

New versions and wiki of this mod will only be available on Data Command Plus (on Modrinth) starting from minecraft 1.21.2

This mod expands the capabilities of /data command, /loot

Only required on the Server side, client will need it for full syntax help!

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 /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)

• … 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| operation)

Squished tree: of /Loot command

/loot <TARGET> <SOURCE>
where
<TARGET> is:

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

<SOURCE> is:

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

<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), (-n) minus will return last n Slots
Equipment in order: Armor feet to head, mainhand, offhand, body, saddle.

Example, compacting inventory from one chest minecart into another one:
/loot insert entity @e[limit=1,type=chest_minecart,tag=1] inventory @e[limit=1,type=chest_minecart,tag=2]
