Client-side Custom Music Disc Fix
by AlphaDS
Client-side Custom Music Disc Fix addresses MC-260346, a bug where custom music discs are cut off before they reach their full vanilla length, on the Fabric loader.
What it does
The fix lets a custom music disc play to its full length on the client, so a track no longer stops early when the disc runs past the vanilla length. It works alongside Fabric API, which the mod requires, and it can read jukebox behavior through the Simulate hopper support jukebox client setting, as the author notes. Only the client needs the mod: players install it, and servers run without it.
Its scope is narrow and focused on the jukebox bug, which makes it suited to players using custom disc packs in single-player or on multiplayer servers. Cloth Config API and Mod Menu are optional dependencies; with them installed, the mod's options can be changed in the in-game menu. The source code, issue tracker and wiki are public, and the code is under the GNU General Public License v3.0 only. Files are published for Fabric alone, with builds for 1.20.1, 1.20.4, 1.21.1, 1.21.4, 1.21.5, 1.21.8, 1.21.11, 26.1.1, 26.2 and 26.3, and 1.1.6+26.3 for 26.3 is the latest.
Key features
Full-length custom discs
Custom music discs play to their full length instead of stopping at the vanilla duration.
Jukebox particle sync
Jukebox particles are synchronized with the client so the note effects match the disc that is playing.
Global disc attenuation toggle
Music disc attenuation can be switched on or off globally, which changes how far a disc is heard.
Hopper-fed jukebox support
A setting simulates hopper support for jukeboxes on the client, so hopper-fed discs behave as expected.
