I can't play the song

[LucidMoH]

I play using software from version 1.3.0 in version 1.20.1, but nothing happens after tuning

You can update your Minecraft version and use 1.3.1/1.3.0 in the updated game version and you can use viafabric to connect to the server which are in the old version.GOOD LUCKS!

1.20.1 here too (can't update due to many mods). 1.3.0 tunes and gets stuck at 0:00 (both on single- and multiplayer), but 1.2.5 works.

My guess is that me making the playback async causes some issues, because somehow the playback thread crashes or gets denied to do it's function because of some other mod or OS restriction.

Can you please be a bit more specific about it?

• Was it in Singleplayer or Multiplayer?
• How often or when does it appear to happen?
• Did it happen when starting your first song (after launching minecraft or joining a world again) or some specific song?
• Does it help to first stop the current song, then playing the next song (/discjockey stop, the play again)?
• Does it happen if you disable most/all other mods? What mods do you use?
• Where you in Creative mode perhaps? Playing noteblocks in it doesn't work (you'd break the blocks instead of playing them) and the mod should notify about that. But could of course be overlooked.

If the playback thread crashes it should also print the reason for it to the console. Can you send the relevant part of the log search for any stacktraces that include the mod?

A stack trace might look roughly like this:

If your launcher doesn't show you your logs, you can try to let it open your minecraft folder. The most recent logs should be located under logs/latest.log (it's a text file you can open with any text editor). Then it's best to use CTRL+F and search for disc_jockey and logs that look similar to the above.

Seems like #17 is a duplicate of this and #18 and #19 are kinda copies of #17 as well. Best to discuss it here, since this is the first report of this bug.

For me:

• it happens in both singleplayer and multiplayer
• always
• first song
• no
• haven't tried, but can if needed
• no

Somehow didn't think to check the logs until now, sorry! (I use Quilt, for the record.)

Interesting. Maybe it's some incompatibility with quilt mappings? I have never used quilt, but afaik they sometimes have slightly different mappings.

The Method that could not be found should be one in this line: https://github.com/SemmieDev/Disc-Jockey/blob/9a925470193ff480ab8d9c69ae567bedb6d5a960/src/main/java/semmiedev/disc_jockey/SongPlayer.java#L169 Likely:

I tried finding out what method it should be with this handy tool: https://wagyourtail.xyz/Projects/MinecraftMappingViewer/App?version=1.20.1&mapping=YARN,QUILT&search=method_52787

It doesn't seem to find it oddly. When though I also had difficulties switching it to Yarn build 1, which this mod uses in 1.20.1.

So maybe a quilt incompatibility or just some outright issue when mapping. Maybe old cache not updating the method from an older version when @SemmieDev built the mod and me just doing a fresh build resolved it. :shrug:

This also proves that the fix will likely not fix anything for you in theory. All it would have done is print you that stacktrace every tick to the logs, as I surrounded the method with a try-cratch to prevent any potential new crash.
