Templates

Filament supports templates, which let you copy properties from one config into another.
This reduces duplication and makes large packs easier to maintain.

Basic Usage

First, define a base template, this can be done by either json/yaml in filament/templates/ or by setting the is_template property.

id: mynamespace:template_item
is_template: true # this is not needed if the file resides in `filament/templates/`
displayName: "<item_id_capitalized>" # this is a placeholder for the title-case verison the item id's path. For `mynamespace:christmas_tree` this would result in "Chistmas Tree"
vanillaItem: minecraft:diamond
item_resource:
  model:
    default: "mynamespace:item/<item_id>"
components:
  max_durability: 500

id: mynamespace:template_item2
is_template: true # this is not needed if the file resides in `filament/templates/`
properties:
  lore: ["Namespace: <item_namespace>"]

Configurations with is_template set to true will only be added as template, not as item/block/etc.

Those templates can then be used in your item/block/decoration/entity configuration like this:

id: mynamespace:custom_item
template: mynamespace:template_item
components:
  dyed_color: 16711935

Multiple templates can be specified like this:

id: mynamespace:custom_item2
templates:
  - mynamespace:template_item
  - mynamespace:template_item2
components:
  dyed_color: 6711935

Available placeholders are:

• <item_id>: For the path of an item id. For mynamespace:christmas_tree this would result in christmas_tree
• <item_id_capitalized>: Title-Case version the item-id's path. For mynamespace:christmas_tree this would result in Chistmas Tree
• <item_namespace>: Namespace of the item-id. For mynamespace:christmas_tree this would result in mynamespace
