helix / Trigger

Class: Trigger

Defined in: core/values/advancement.ts:17

One advancement trigger with its conditions, built from typed concepts (no hand-written JSON). The conditions are sourced from the same ItemValue you'd give, so an item's "fires when used/attacked with" check matches the exact item that was granted - one definition, like Predicate.

Trigger.usingItem(wand) // right-click / use of the item Trigger.playerHurtEntity(wand) // attacked something while holding it

playerHurtEntity()

static playerHurtEntity(item, slot?): Trigger

Defined in: core/values/advancement.ts:42

minecraft:player_hurt_entity - fires when the player damages an entity while holding item in slot (default main hand). The held-item gate reuses Predicate.holding, so "attacked with this item" matches the same way "holding this item" does.

Parameters

item

ItemValue

slot?

"mainhand" | "offhand"

Returns

Trigger

usingItem()

static usingItem(item): Trigger
