Structure Dependent Music
by FusionSwarly
Structure Dependent Music lets a structure play its own background track, so the music changes when a player enters a generated structure such as a Trial Chamber or a crypt.
What it does
Each structure can carry a background track that plays while the player is inside it. The mod includes music for several structures out of the box, among them Trial Chambers, Lone Citadel, Toxic Lair, Undead Crypt and Creeping Crypt, and it also covers some structures from Dungeons and Taverns.
Structures can be added or removed through a configuration file, so a server owner decides which generated places get music. The mod is built for Fabric only, and it runs on client and server, so the server and every player need it. Files cover Minecraft 1.21, 1.21.1 and 1.21.3, with 0.0.8 for 1.21.3 as the latest file, and the code is licensed under the MIT License as open source.
Snapshot builds are published for the mod as well, and the source code and issue tracker are public, so players can read the code or report problems.
