Overview

An item predicate is a condition that evaluates an item and returns either 'true' or 'false'.

Types

Material​

Returns 'true' if the item is the specified type.

Layout​

"<material key>"

Examples​

"minecraft:diamond"
"minecraft:grass_block"

Any Of​

Returns true if any of the children predicates match.

They are checked in the order they are specified in.

Layout​

type: "any_of"
values:
- <item predicate>

Examples​

type: "any_of"
values:
- "minecraft:diamond"
- "minecraft:stone"
- "minecraft:deepslate"

More sophisticated and unreasonable way to define the same thing as above:

type: "any_of"
values:
- "minecraft:diamond"
- type: "any_of"
  values:
  - "minecraft:deepslate"
  - "minecraft:stone"

Returns 'true' if the item is a diamond, stone, or deepslate.

Material Tag​

Returns 'true' if the item matches any of the materials provided in an ItemTag.

Layout​

"#<material tag>"

Examples​

"#minecraft:planks"
"#crux:wooden_planks"
