Components

Backpack Component

The filament:backpack component can be used to turn any item with a container component into a "portable" container that can be opened by using the item in-hand.

Containers of any size are supported.

Fields:

• size: Size of the container
• prevent_placement: Prevents placement for block-items
• title_prefix: Allows for a custom background using fonts. Make sure to use negative spacing the width of the menu, in order for the normal container name to be in the correct position.
• sneak_only: Will only open the backpack when the player is sneaking

Example usage: /give @s minecraft:poppy[filament:backpack={size:27,prevent_placement:true},container=[]]

As json:

{
  "components": {
    "filament:backpack": {
      "size": 108,
      "prevent_placement": true,
      "title_prefix": "<font:customui:menus>A</font><font:customui:negativespace>X</font>"
    }
  }
}

Skin Components

Filament comes with 2 components that any item to be skinned (visually) by any other item.

You can for example create a diamond pickaxe skin that can be applied to a wooden pickaxe or a diamond. The wooden pickaxe would look like a diamond pickaxe but function like a wooden pickaxe. You could also allow the diamond pickaxe skin to be applied to shovels too!

Filament cosmetics are also supported, which allows you to create cosmetic skins!

Player can simply drag a skin onto the item they want the skin applied to.

Skin Component Format

The filament:skin component works similar to the minecraft:repairable component. You can either specify a list of items or an item-tag, for which item you want the skin to be applicable for.

{
  "components": {
    "filament:skin": ["minecraft:wooden_pickaxe", "iron_pickaxe"]
  }
}

You can also use item-tags:

{
  "components": {
    "filament:skin": "#minecraft:pickaxes"
  }
}
