RegionSpawnMobs 2.0.2

Version 2.0.2 adds safe zone inheritance between related regions, per-mob light-level spawn control, and important fixes to the Region and Zone configuration interfaces.

Zone Inheritance

• Zones in a child region can now select a zone from the parent region as their parentArea.
• Inheritance is restricted to a zone belonging to the child's direct parent region in the same world.
• The UI displays the parent zone name while storing and using its UUID, preventing conflicts between duplicate names.
• When a child zone has no local entities, it automatically uses the entities and settings from the selected parent zone.
• Adding entities directly to the child zone creates a local override, so the inherited list is not used while the local list is non-empty.
• Spawning, maxAlive limits, and reconciliation now correctly recognize inherited zone settings.
• A zone referenced as a parent by a child region cannot be removed accidentally.
• Legacy references that use a zone name remain supported for compatibility.

Per-Mob Light Condition

• Added maximumLightLevel to each mob's SpawnConditions in Regions, Zones, and Markers.
• The value can be configured from 0 to 15:
  • 0 allows only complete darkness.
  • Intermediate values accept lighting up to the selected level.
  • 15 is the default and does not restrict spawning by light.
• The condition is evaluated at the candidate position before the mob is spawned.
• Light is averaged over an 8 x 4 x 8 volume, matching Hytale's local spawner behavior instead of reading a single block.
• Solid blocks are excluded from the average.
• Added a heightmap-based fallback to correctly recognize skylight in chunks where lighting data is not yet available or is incorrect.
• A missing valid light reading safely blocks mobs that have an active light restriction.
• Added detailed SPAWN_VERBOSE light diagnostics, including the average, configured maximum, sample count, and skylight corrections.

Dynamic Light Reconciliation

• Added the Region option dynamicLightReconcile (Sync Mobs with Light Level).
• When enabled, tracked mobs are checked again at their current position instead of only at their original spawn position.
• Mobs whose current light exceeds their maximumLightLevel are removed by the reconciler.
• When disabled, light controls spawning only and does not remove living mobs after environmental changes such as placing a torch.
• Light reconciliation remains separate from time, weather, and other dynamic-condition reconciliation.

Region, Zone, and Mob UI

• Added a mob-target dropdown that selects the Region itself or one of its Zones.
• Fixed target selection incorrectly returning to the Region after choosing a Zone.
• Adding, editing, and removing mobs now operates on the selected target correctly.
• The Region list in the Zones screen is now sorted by distance from the player, with the nearest regions shown first.
• Adjusted the Region dropdown to use a large fixed width, improving usability with many regions or long names.
• Added a parent-zone dropdown with an explicit apply action to child zones.
• Fixed parent-zone dropdown value submission and the resolution between the displayed name and stored UUID.
• Improved validation messages for missing, invalid, or out-of-scope parent-zone references.

Entity IDs and Compatibility

• Removed lowercase normalization from Zone mob IDs.
• Entity IDs now preserve the exact letter casing supplied by Hytale, matching existing Region behavior.
• Saving an entity again migrates legacy lowercase keys to the exact ID without creating duplicates.
• Mob removal retains a compatibility lookup for older configurations that still contain normalized IDs.
• Existing configurations remain compatible; new fields use safe defaults when absent.

Fixes

• Fixed inherited entities not spawning inside child zones.
• Fixed maxAlive calculation and entity-config resolution during inherited-zone reconciliation.
• Fixed light readings for flying mobs in open air during daytime.
• Fixed incomplete chunk lighting data being incorrectly interpreted as light level 0.
• Improved spawn and reconciliation diagnostics for rejected light conditions.

Verification

• Full project build completed successfully.
