Trigger Types

All three systems share the same trigger block.

What can unlock something

Titles and journeys are checked every few seconds. Milestones react to the event itself.
  • advancement: the player has an advancement, e.g. minecraft:end/kill_dragon
  • statistic: a vanilla statistic reaches a value, retroactive
  • counter: a Legacy counter reaches a value, e.g. harvest:crops, biomes_distinct, place:saplings, bonemeal:used, mine:#minecraft:logs
  • item: the player holds an item anywhere in the inventory
  • custom: a predicate registered by another mod
  • kill / dimension: milestones only, first kill of an entity or first visit to a dimension
  • Legacy counters start at 0 when the mod is installed
