Custom item NBT

Adding custom NBT attributes to the item

You can specify custom NBT attributes to be merged into the custom item.

Make sure to provide a valid NBT (json) or it won't work!

NOTE

Make sure to escape the " character using \. Use my Escape/Unescape tool to escape the string before using it in the YML.

This feature supports legacy NBT and the new 1.20.5+ modern NBT too! It will automatically convert the legacy NBT if needed.

More info on the 1.20.5+ changes (scroll down).

Example custom attribute

For example I want to merge these tags into my item: nbt: '{my-custom-nbt-tag:"hello this is a custom tag", another-tag:"useless"}'

items:
  custom_nbt_item_data:
    display_name: "Injected nbt data into this item"
    lore:
    - 'test item: custom_nbt_item_data'
    - 'test line from IA config 1'
    - 'test line from IA config 2'
    - 'test line from IA config 3'
    permission: examples.test
    nbt: '{my-custom-nbt-tag:"hello this is a custom tag", another-tag:"useless"}'
    resource:
      material: DIAMOND_SWORD
      generate: false
      model_path: "minecraft:item/diamond"
    durability:
      durability: 650
      max_durability: 1324
    attribute_modifiers:
      mainhand:
        attackDamage: 30
        attackSpeed: 25

nbt: "{components:{"minecraft:custom_name":'{"text":"TEST", "font": "alt", "italic":false}', "minecraft:custom_data": {"bro":'asd'}}}"

Old 1.20.4 Component - don't use this

This is an old way, don't use it.

nbt: "{display:{Name:'{"text":"TEST", "font": "alt", "italic":false}'}}"

    enabled: true
    display_name: custom_nbt_item_custom_name_legacy_nbt

    - 'test item: custom_nbt_item_custom_name_legacy_nbt'
    - 'test line from IA config 1'
    - 'test line from IA config 2'
    - 'test line from IA config 3'
    permission: custom.test
    nbt: "{display:{Name:'{\"text\":\"TEST\", \"font\": \"alt\", \"italic\":false}'}}"
    resource:
      material: DIAMOND_SWORD
      generate: false
      model_path: "minecraft:item/diamond"
