Using NBT Data with the 'Custom-Tags' Section

This guide explains how to use the Custom-Tags section to apply NBT data to custom items. Below are examples of how to use Custom-Tags to set various properties such as spawner IDs, attribute modifiers, and leather armor colors.

Example: Set Mobs to an Empty Spawner

Custom-Tags:
  - path:
    - SpawnerID
    value: Zombie

This configuration sets the SpawnerID to spawn a Zombie.

Example: Add Attribute Modifier (Attack Damage)

Custom-Tags:
  - path:
    - AttributeModifiers
    value:
    - Name: CustomAttackDamage
      AttributeName: generic.attackDamage
      Amount: 100.0
      Operation: 0
      Slot: mainhand

This configuration applies a custom attribute modifier that increases attack damage by 100.0 when the item is held in the main hand.

Example: Set Leather Armor Color

Custom-Tags:
  - path:
    - display
    - color
    value: 16711680

This configuration sets the leather armor color to red using the RGB value 16711680 (hex: #FF0000).

Example: Set Potion Types

Custom-Tags:
  - path:
    - potion
    value: STRENGTH
    extended: true
    upgraded: false

This configuration sets the potion type to a strength potion.

Example: Set Enchanted Book Enchantments

Custom-Tags:
  - path:
    - Enchantments
    value:
      sharpness: 5
      efficiency: 4

This configuration results in an enchanted book with both sharpess 5 and efficiency 4.

Key Notes

NBT Paths: The path field defines the specific NBT path for the property being set. Each segment of the path should be listed as an array item.

Value Format: The value field specifies the value to assign at the specified NBT path. For nested structures, use arrays and key-value pairs as needed.
