Triggers and criteria
An advancement completes when its requirement criteria are met. Select a trigger that matches the event you want, then extend conditions manually if the trigger needs a specific item, entity, or location.

Quick questions
Will every trigger work without conditions?
Some triggers can complete broadly without conditions. Add target-specific conditions before publishing a serious datapack.
Where does the file go?
Use the displayed data/<namespace>/advancement path in the datapack.
