Advancement/JSON format

Custom advancements in data packs of a Minecraft world store the advancement data for that world as separate JSON files.

File Format

All advancement JSON files are structured according to the following format:

The root tag.
- display: The optional display data.
  - icon: The data for the icon.
    - item: The item id.
    - nbt: The nbt data of the item.
  - title: The title for this advancement.
  - title: A JSON text component (containing text and formatting like used in /tellraw and various other commands. Also translate tag can be used here).
  - frame: The optional type of frame for the icon. challenge for a tile with a more fancy spiked border as it is used for the kill all mobs advancement, goal for a tile with a rounded border as it is used for the full beacon advancement, task for a normal tile (default.)
  - background: The optional directory for the background to use in this advancement tab (used only for the root advancement).
  - description: The description of the advancement.
  - description: A JSON text component (containing text and formatting like used in /tellraw and various other commands. Also translate tag can be used here).
  - show_toast: Can be true or false. Whether or not to show the toast pop up after completing this advancement. Defaults to true.
  - announce_to_chat: Can be true or false. Whether or not to announce in the chat when this advancement has been completed. Defaults to true.
  - hidden: Can be true or false. Whether or not to hide this advancement and all its children from the advancement screen until this advancement have been completed. Has no effect on root advancements themselves, but still affects all their children. Defaults to false.
- parent: The optional parent advancement directory of this advancement. If this field is absent, this advancement is a root advancement. Circular references cause a loading failure.
- criteria: The required criteria that have to be met.
  - <criterionName>: A name given to the criterion (can be any string, must be unique).
    - trigger: The trigger for this advancement; specifies what the game should check for the advancement.
    - conditions: All the conditions that need to be met when the trigger gets activated.
- requirements: An optional list of requirements (all the <criteriaNames>). If all criteria are required, this may be omitted. With multiple criteria: requirements contains a list of lists with criteria (all criteria need to be mentioned). If all of the lists each have any criteria met, the advancement is complete. (basically AND grouping of OR groups)
- rewards: An optional object representing the rewards provided when this advancement is obtained.
  - recipes: A list of recipes to unlock.
    - A namespaced ID for a recipe.
  - loot: A list of loot tables to give to the player.
    - A namespaced ID for a loot table.
  - experience: An amount of experience.
  - function: A function to run. Function tags are not allowed.

Display

Within the root tag of an advancement JSON object, the display field and the parent field, both optional, are related to the display of the advancement.

If the display tag is present, it must have both the title and description fields present in order to be a valid advancement display data.

The parent field, albeit not directly associated with the display data of an advancement, affects only the display data effectively. When an advancement does not have a display data and none of its children has a display data, the parent of the advancement has no effect to the advancement itself.

Tab creation

To create a tab in the advancement menu, define a root advancement (an advancement without a parent) with a display. When the data pack containing the advancement is loaded, the root advancement shows a tab in the advancement menu when any advancement in its advancement tree is granted to the player viewing the menu.

When a background is not specified for a root advancement, the tab is still created, but with the tab background appearing as the missing texture.

Presence

For a non-root advancement (i.e. an advancement with a parent defined), these conditions must be met in order to have it displayed in a tab when unlocked:

Its root advancement must be a valid tab.
It must have a display.

Position

The game automatically arranges advancements, position them when it loads advancements from data packs, and sends the arrangement to the client. Each advancement has an arrow from its closest visible ancestor (i.e. if its parent does not have a display, it has a link from its grandparent, and so on). The root advancement appears on the leftmost column while each arrow points to an advancement in the next column. The arrangement of advancements within a column is based on file name.

Lack of Display

Some advancements, such as the vanilla recipe unlocking advancements, may lack a display so that they can utilize triggers and rewards instead of excessive commands or functions for more functionalities and a more flexible control. These advancements should not have the display field defined in order to hide from users and enjoy a better loading performance.
