Origin JSON Format

This is the format of a JSON file describing an origin. Origins are used to give players special abilities, which can alter the player's gameplay.

Origin JSON files need to be placed inside the data/<namespace>/origins folder of your datapack. The said files can be referenced as namespace:path/to/origin (data/namespace/origins/path/to/origin.json) in the origins field of an Origin Layer (JSON) file.

Fields

Field	Type	Default	Description
powers	Array of Identifiers	optional	The namespace and IDs of the powers this origin should have.
icon	Item Stack	optional	The item stack which is displayed as the icon for the origin in the top-left corner of the choose/view origin screen.
unchoosable	Boolean	false	If set to true, this origin will not show up in any origin layer to choose it, but it will still be able to be set for that layer with a command or via an origin upgrade.
order	Integer	optional	Specifies the position of this origin in the choose origin screen among the other origins with the same impact in the layer. If not specified, will be a really large number - basically adding it in the end.
impact	Integer	0	Specifies the impact of this origin with a number from 0 (none) to 3 (high).
name	String	optional	The display name of the origin. Can be a translation key which is localized in a language file, or the literal display name.
description	String	optional	The description of the origin. Can be a translation key which is localized in a language file, or the literal description.
upgrades	Array of Upgrades	optional	A list of upgrades for this origin, specifying which advancements turn this origin into which other origin.
loading_priority	Integer	0	Specifies when this origin is loaded. Higher numbers mean it's loaded later, which means it will override those with lower loading priorities which share the same ID.

Examples

{
    "powers": [],
    "icon": {
        "item": "minecraft:zombie_head"
    },
    "order": 3,
    "impact": 2,
    "name": "Zombie",
    "description": "Raah, brains..."
}

This example will add an origin that has a Zombie Head item as its icon.
