Music Regions NeoForge 1.21.1 — Fixes and Feature Update

This update replaces the previous broken build and includes several important playback fixes and new features.

Fixed

• Fixed region music failing to start when fade-in was enabled.
• Fixed vanilla Minecraft music continuing inside Music-type regions.
• Fixed duplicate tracks appearing when rapidly entering and leaving regions.
• Fixed faded-out tracks sometimes continuing indefinitely.
• Fixed /music link entity selectors not functioning correctly.
• Fixed linked entity and location music having unlimited audible range.
• Fixed linked music staying at the same volume regardless of distance.
• Fixed linked music restarting after briefly leaving its radius.
• Fixed overlapping-region fallback after removing a painted chunk.
• Improved multiplayer synchronization for regions, track settings, and linked music.

Region sound types

Added a Type setting to each region:

 - Music
  - Weather
  - Players
  - Jukebox/Note Block
  - Block
  - Ambient

Each type is controlled by its corresponding Minecraft sound-volume slider. Regions with different sound types can now overlap and play simultaneously. If overlapping regions use the same sound type, the region with the higher priority plays. Example:

- A city region can play its soundtrack through the Music category.
- An overlapping tavern region can play additional audio through Jukebox or Ambient.
- Both tracks can play together and be controlled separately.

Global track settings

Tracks can be configured through the new Edit Track screen:

- Volume
- Fade-in duration
- Fade-out duration
- Day playback
- Night playback
- Other-dimension playback
- Hostile/combat music
- Hostile activation level

Track settings are global, saved with the world, and synchronized with connected players.

Day and night music

- Regions can contain separate day and night tracks.
- Only tracks eligible for the current time are selected.
- Tracks can be enabled for both day and night.
- Music automatically changes when the time eligibility changes.

Combat music

- Tracks can be marked as hostile/combat music.
- Combat music is selected from a global hostile-track pool.
- Combat music temporarily overrides regular regional music.
- Regional music resumes after combat.
- Four hostile activation levels are available.

Entity and location music

Music can be linked to entities:

/music link <entity> <track> <volume> <radius> <day|night|any>

Music can also be linked to named coordinates:

/music link <x> <y> <z> <locationName> <track> <volume> <radius> <day|night|any>

Management commands:

/music link remove <target> <track>
/music link pause <target>
/music link resume <target>

Linked-music improvements:

- Supports entity UUIDs, custom entity names, and Minecraft @ selectors.
- Selectors can target one or multiple entities.
- Supports multiple tracks per entity or location.
- Audio follows moving entities.
- Volume decreases as the player moves away.
- Audio becomes silent at the configured radius.
- Tracks continue progressing silently outside the radius and do not restart when the player returns.
- Positional stereo tracks are handled automatically without modifying the original files.
- Links persist across restarts and synchronize in multiplayer.

Interface improvements

- Added the Track Settings screen.
- Added the region sound-type selector.
- Improved Music Manager layout and smaller-resolution support.
- Fixed blurry GUI panels.
- Improved track-search suggestions and dropdown rendering.
- Repositioned several controls for readability.
- Added a Back button to the Track Settings screen.
