Sounds and music discs - LodeItems

items/sounds/sounds.yml

victory:
  type: sound
  file: victory.ogg            # next to this file
  stream: true                 # for long sounds like music
  volume: 1
  pitch: 1
  distance: 32                 # heard from this far away (default 16)
  subtitle: "Fanfare plays"

The sound’s id is lodeitems:victory, the same as any other id. Play it from actions ([sound] lodeitems:victory), from block and prop sounds:, or with /playsound. Sounds must be Ogg Vorbis (.ogg) files. For sounds that come from a spot in the world, use mono files, because stereo sounds are heard at the same volume everywhere.

Several variations

coin:
  type: sound
  files: [coin_1.ogg, coin_2.ogg, coin_3.ogg]   # one is picked at random each time

Music discs

Add disc: to make the sound a song that jukeboxes can play:

victory:
  type: sound
  file: victory.ogg
  stream: true
  disc:
    description: "<gold>LodeMC - Victory"
    length: 2m30s
    comparator: 15             # comparator signal while it plays (0-15)

Then make a disc item that plays it:

victory_disc:
  material: music_disc_cat
  name: "<gold>Music Disc"
  texture: victory_disc.png
  components:
    jukebox_playable: "lodeitems:victory"

Minecraft only accepts new music disc songs at startup. Adding or removing a song needs a server restart. A reload tells you when that’s the case. Changing the sound file itself only needs a reload.
