Module trigger 

Environment triggers and the props a player interacts with.

Structs

EnvTrigger

A stage-5 environment trigger (DSL v0.4). Emission uses vanilla-intended primitives only (spec-0008 §7): strike/use read a minecraft:interaction entity’s attack/interaction records; approach is a distance selector on the tick. Look-at / break-attempt detection is excluded on principle (no vanilla primitive).

Prop

A prop block for an interact objective or a use trigger (DSL v0.4; spec-0093 §6.5). The block is the affordance the player interacts with; its id is validated against the pinned 1.21.11 block registry (DW0193).

Enums

TriggerAudience

Who an EnvTrigger’s effects address (DSL v0.11).

TriggerOn

The event an EnvTrigger watches (DSL v0.4).

Constants

SEALED_BODY_UNANSWERED

(v0.11) A sealed body with no press answer, uniformly over the pressable class. A shortcuts[] door or a close-gate’s wall is sealed, and nothing says what it answers when the party presses it — no use trigger anchored on it, and (for a close-gate) no authored sealed_hint.

TRIGGER_AUDIENCE_UNATTRIBUTABLE

(v0.11) A press answer addressed to a click vanilla cannot attribute. A trigger declares audience: presser on something other than an on: use or an on: step.

TRIGGER_ID_RESERVED

(v0.11) A trigger id in the compiler’s reserved dw- namespace. The compiler synthesizes triggers of its own — today the press answer every sealed gate and shortcut door gives (trigger/dw-press-…) — and two triggers sharing an id would share one dw_trig_… tag and one emitted function, so one of them would silently disappear. Reserving the prefix makes the collision impossible by construction instead of improbable.

TRIGGER_INVALID

(v0.4) An environment trigger id is malformed (DW0110-style) or duplicated within the stage-5 triggers namespace.

USE_TRIGGER_ON_NPC

(v0.4, added round-6) A use trigger anchored where an NPC stands. Right-click on an NPC already belongs to its dialogue advancement; a second interaction hitbox in the same cell makes the client’s entity ray-pick ambiguous, and whichever entity loses the tie is silently dead — the round-6 island soft-lock class (an exactly co-located hitbox starved the giant’s dialogue of every right-click). strike triggers are exempt: a left-click has no dialogue meaning, so the compiler rides the trigger’s tag on the NPC’s own hitbox instead of summoning a second one. Validation-tier (exit 1).
