feat(pipeline): add WTRG (Wowee Area Trigger) format
Novel open replacement for Blizzard's AreaTrigger.dbc +
AreaTriggerTeleport.dbc + the AzerothCore-style
areatrigger_template / areatrigger_teleport SQL tables.
The 29th open format added to the editor.
Defines proximity-based event zones — when a player enters
a defined region (box or sphere), the runtime fires the
trigger's action: teleport to another map, award
exploration XP for a quest, run a server script, gate an
instance entrance behind a key item, mark a PvP boundary,
or simply display a "Discovered: {area name}" banner.
Cross-references with previously-added formats — every
trigger field has a real format target:
WTRG.entry.mapId / areaId -> WMS.map.mapId / WMS.area.areaId
WTRG.actionTarget (Teleport) -> WMS.mapId
WTRG.actionTarget (QuestExploration) -> WQT.questId
WTRG.requiredQuestId -> WQT.entry.questId
WTRG.requiredItemId -> WIT.entry.itemId (key)
Format:
• magic "WTRG", version 1, little-endian
• per trigger: triggerId / mapId / areaId / name /
center vec3 / shape / kind / boxDims vec3 / radius /
actionTarget / dest vec3 / destOrientation /
requiredQuestId / requiredItemId / minLevel
Enums:
• Shape (2): Box / Sphere
• Kind (7): Teleport / QuestExploration / Script /
InstanceEntrance / AreaName / CombatStartZone /
Waypoint
API: WoweeTriggerLoader::save / load / exists / findById.
Three preset emitters showcase common trigger shapes:
• makeStarter — area-name + quest-exploration with
cross-ref to WQT 100 ("Investigate the
Camp")
• makeDungeon — outdoor area-name + portal-style
InstanceEntrance with Deadmines key
gate (WIT itemId 5200, matches
WLCK.makeDungeon's Boss Vault Seal) +
interior exit teleport back outdoors
• makeFlightPath — 2 sphere waypoints near flight masters
so the runtime can auto-open the
flight UI on proximity (matches WTAX
starter node positions)
CLI added (5 flags, 601 documented total now):
--gen-triggers / --gen-triggers-dungeon / --gen-triggers-flightpath
--info-wtrg / --validate-wtrg
Validator catches: triggerId=0 + duplicates, unknown shape /
kind, non-finite center, sphere with radius<=0, box with
all-zero half-extents, teleport / instance with dest=(0,0,0)
(silently does nothing — usually a typo), QuestExploration
without an actionTarget questId.
