EMDungeonLocator

DungeonLocator implementation backed by EMPackage's static world registry. A location counts as being inside EliteMobs content whenever its world is owned by any WorldPackage subclass — open-world dungeons, instanced dungeons, dynamic dungeons, and hub/story worlds all qualify. Non-world package types (items, events, meta, models) aren't keyed by world name and never match.

Intended to gate anti-exploit checks that should cover every EM-managed world, not just the narrow "dungeon" subset, since content-pack scripts usually want to block interaction across every EliteMobs content world. The query is an O(1) HashMap lookup against the world name.
