Hello, I just finished my first mod for MC for 1.19.2, I've used: IntelliJ 2024.1.3 Forge MDK 43.4.0 SDK 17.0.11 (Adoptium) Basically, my mod plays scary music at night time, stopping any music played by the game. For that I needed to access via reflection to a private MusicManager.class attribute (SoundInstance currentMusic), and the management of this is giving me errors (I think). Here's the full stacktrace: ---- Minecraft Crash Report ---- // There are four lights!

Finally, I fixed it and now it's working

Hi! This is my first time creating a mod in Minecraft. It will be for personal use, and the goal is to play creepy/scary music at night. I want it to play without overlapping with Minecraft music (C418, etc.). I have almost finished it, but I don't know how to detect if Minecraft music is playing. I tried accessing a "currentMusic" variable in the MusicManager class via reflection, but it doesn't work. Class<?> musicManagerClass = musicManager.getClass(); java.lang.reflect.Field currentMusicField = musicManagerClass.getDeclaredField("currentMusic"); currentMusicField.setAccessible(true); currentMusic = (SoundInstance) currentMusicField.get(musicManager); Does anyone know how to do it?
