Minecraft:Slot sources

Template:Exclusive Template:Move Template:Improve lead Template:Wip Slot sources provide any number of Minecraft:inventory slots in Minecraft:data packs via Template:Cd type Minecraft:loot table entries and in slot_source argument type of Minecraft:commands.

Definition

Slot sources may be defined inline, or stored as Minecraft:JSON files and referenced elsewhere, as part of the data pack directory structure:

The root element of a slot source file can be either an Template:Nbt following the slot source structure below, or an Template:Nbt containing multiple slot sources. In the latter case all resulting slots from each source are concatenated together, acting as a shorthand for the Template:Cd type.

Format

• Template:Nbt: The root tag.
  • Template:Nbt: The slot source type as a Minecraft:resource location. May be any of Template:Cd.
  • Extra fields of the slot source depending on Template:Nbt, described below.

The type values can omit or include the namespace Template:Cd, for example using the type Template:Cd or Template:Cd has the same effect.

Inventory-based types

These types select any number of slots from an inventory provided by Minecraft:loot context.

empty

Empty selection containing no slots.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • No additional fields.

slot_range

Selects slots within a slot range from the inventory of an entity or block entity. Mirrors the behavior of the item_slots used in Template:Cmd previously from the slot source.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • Template:Nbt: (optional, defaults to Template:Cd) An entity or block entity from which the slots will be sourced, from loot context. Can be Template:Cd, Template:Cd, Template:Cd, Template:Cd, Template:Cd, Template:Cd, Template:Cd or Template:Cd.
  • Template:Nbt: Slot range in the format of Template:Cd or Template:Cd, wildcard (Template:Cd) is accepted (e.g. Template:Cd or Template:Cd)

Inheriting types

The types below restrict, merge or expand on existing slot sources.

group

Merges several slot sources into one, with the resulting selection containing all slots from each slot source provided in the order they appear in Template:Nbt. If a slot is included in more than one slot source, it will be repeated in the resulting slot source.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • Template:NbtTemplate:NbtTemplate:Nbt: List of slot sources to join. Has to be inline if the group is top-level to avoid circular definitions.

contents

Selects all non-emptyTemplate:Until slots from the inventory component of one or more items. If no item is stored inside that component, the resulting selection will be empty. If Template:Nbt results in more than one item with that component, the resulting selections will be concatenated as with the Template:Cd type.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • Template:Nbt: The inventory component to target. Allowed values are Template:Cd, Template:Cd, and Template:Cd.
  • Template:NbtTemplate:NbtTemplate:Nbt: A slot source containing slots with item(s) to target.

filtered

Applies a filter to the selected slots, excluding any non-matching slots from the resulting selection.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • Template:Nbt: An Minecraft:item predicate to match against the items in each slot.
    • Template:Nbt inherit/conditions/item
  • Template:NbtTemplate:NbtTemplate:Nbt: The slot source to filter.

limit_slots

Limits the number of slots provided, with the resulting selection containing at most that number of slots. Any slots bringing the number of slots above that limit will be excluded, in order of inclusion.

• Template:Nbt: A slot source
  • Template:Nbt: Template:Cd
  • Template:Nbt: The maximum number of slots to include in the resulting selection.
  • Template:NbtTemplate:NbtTemplate:Nbt: The slot source to limit.

Example
