Squished tree: of /data command

• … 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)
  • … from (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>]
  • … concat (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>]
  • … string (block <sourcePos>|entity <source>|storage <source>|storageplayer <player>) [<sourcePath>] [<start>] [<end>]
  • … <(operation one of: =, +=, -=, *=, /=, %=, ^=, <, >)> <double value>
  • … value <value>
• … remove (block <targetPos>|entity <target>|storage <target>|storageplayer <player>) <path>

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), minus will return last n Slots

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]

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
• for command syntax help install this mod client side
• Return result and success: non zero on success

Storageplayer

• store data per player in their own file /players/<UUID>_pds.dat
• works only on players, any other entity will return an error
• ! 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) ...
• Return result: Slots returned

/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)
Examples of Loot ... inventory ... can be found in datapack Fafik77 Lib/inventory_manager
