To add bags to your game, you must create a data pack. Bag types are defined in the following directory: data/<namespace>/treasure_bags/bag_types/<name>.json.

JSON Structure

A bag type file requires several key fields to define its appearance and behavior:

Field	Type	Description
`name`	String/Object	The display name of the bag. Supports raw strings or JSON text components (for translations/colors).
`bagColor`	Hex String	The primary color of the bag texture (e.g., `"0xFFFFFF"`).
`bagStringColor`	Hex String	The color of the string tied around the bag (e.g., `"0x000000"`).
`lootTable`	Resource Location	The ID of the loot table to roll when the bag is opened.
`rarity`	String	The rarity color of the item name (common, uncommon, rare, epic).
