Jukebox: Merge Music Packs

Have you ever felt indecisive on what music pack to use? Have you ever wished you could use multiple music packs... all at the same time? Well wish no more! This mod lets you use all of your favourite music packs together with just a simple click. Load into a world and let the mod do its magic, all music packs will be used and tracks will be picked out at random depending on the biome, time, and weather. This works with music boxes too! Hence the name JukeBox...

Jukebox: Merge Music Packs is a mod that randomizes music from all enabled resource packs instead of just the top one, allowing you to use multiple music packs at once and experience all of them.

COMMANDS:

/next - plays a track at random out of your music packs (based on what biome you are in, with time and weather considered)
/song - tells you what track is currently playing in the chat, as well as what resource pack its from, who the author is, and what the track ID is.

WHAT DOES THIS DO?

In detail, this mod uses complex but lightweight systems to randomize the song that is used from your music packs that are enabled. This mod entirely bypasses the standard Terraria and tModLoader Resource Pack prioritization system, which normally loads assets only from the single, top-most enabled pack. It does this through a multi-layered approach: first, a specialized scanner accurately reads the user's config.json file to build a strict, verified list of all truly enabled music packs, ensuring disabled packs are never included.

Second, using the ModSystem.PostUpdateEverything hook, the mod intercepts the game's music selection after the vanilla biome/time/event logic decides which song ID to play. Instead of allowing the vanilla game to retrieve the single cached song for that ID, the mod selects a file at random from its indexed list of variants. Finally, it uses Reflection to manually instantiate a specialized IAudioTrack (OGG, MP3, or WAV) by creating a fresh MemoryStream of the chosen file's data. This new, random track is then injected directly into the game's live audio array, wrapped in a SafeAudioTrack class that catches critical stream/format errors, allowing the engine to skip corrupted songs without crashing the entire game.

This combination of deep system access and safety wrappers forces Terraria to play randomized music from all enabled sources.

KNOWN BUGS

- Resource packs that are disabled, but are installed, play their tracks. // Im not sure how to fix this, but i am working on it. If anyone has a fix, lmk in the comments. Fixed!
- An error message appears occasionally, upon entering a new biome or on startup of a world. // I will fix this ASAP Fixed!


Enjoy!
