What is This?

FoxNap is a simple "Vanilla Plus" mod for adding custom music discs to Minecraft.

Unlike what you can achieve with resource packs alone music discs added via FoxNap do not overwrite the vanilla music discs.
Unlike similar mods, FoxNap allows you to:
- add as many or as few music discs as you want
- add whatever music you want
- use different music than other players on the same server
- obtain all music discs in survival, via a new villager profession (utilities for modifying creeper / treasure chest loot tables are planned)

FoxNap also adds custom musical instruments that you can play like goat horns, giving you the creative freedom to stage "live music" performances.

Motivation

I started work on this mod after being inspired to extend the SBM Jukebox mod, which brings the Bedrock music disc playlist functionality to Java. I wanted to add an outdoor concert venue to my survival world (the name FoxNap is an homage to the Wolf Trap center for the performing arts, which was a huge fixture of my childhood), but what I kept getting hung up on was how I could source and provide the music without violating copyright--forget about adding my own personal music collection, even YouTube's "Free" audio library was off-limits, as the license terms explicitly state:

You may not make available, distribute or perform the music files from this library separately from videos and other content into which you have incorporated these music files (e.g., standalone distribution of these files is not permitted).

As I saw it, there were two options for getting around this limitation (besides abandoning the project or not sharing this mod with anyone)

Limit the music included with the mod to permissively-licensed (public domain, attribution or copyleft) audio
Allow users to provide their own music via a config or a resource pack

In the end, I decided, why not both?

Setup and Customization

This mod comes pre-bundled with seven new music discs:

Four tracks performed by PM Music from Lud and Schlatts Musical Emporium

Nikokai Rimsky-Korsakov: "Flight of the Bumblebee" from Tsar Saltan, performed by The US Army Band

all of which are permissively licensed under the terms specified here (I am redistributing them via this repo and mod under the compatible Creative Commons Attribution-ShareAlike 4.0 License).

If this built-in playlist sounds like your jam, and you have no desire to add anything else, then congrats! This is easy! This is a Fabric mod with builds for 1.19+ and depends only on the Fabric API, so just download the appropriate build to your instance's mods folder, start the game, and go find a village.

But if you're interested in some customization, read on:

Manual Resource / Data Pack Creation

FoxNap's item and sound registration structure was designed to make it as easy as possible for you to replace or add to the mod's built-in tracks via a resource pack similar to what you'd make if you were replacing one of the vanilla discs, with the advantage that the number of discs provided by the mod is completely dynamic and can be set or changed simply by going into your instance's mod config folder, opening foxnap.yaml in any plaintext editor and changing the value of n_discs.

From there, if you're used to vanilla disc replacement resource packs, the differences will be:

instead of assets/minecraft, all your files should be in assets/foxnap
the ids of the sound files you'll be replacing (in assets/foxnap/sounds.json) will be foxnap:track_1, foxnap:track_2, etc. all the way up to the number n_discs you set in the foxnap.yaml config file stored in your instance's mod config folder.
to set or replace the record textures, you'll need to create files named track_1.json, track_2.json, etc. within assets/foxnap/models/item
when changing the names of the tracks to display, you'll need to edit assets/foxnap/lang/en_us.json and refer to the language entries as item.foxnap.track_1 / item.foxnap.track_1.desc, item.foxnap.track_2 / item.foxnap.track_2.desc, etc.
you'll also likely need to create a custom datapack with files in a data/foxnap/jukebox_songs folder that set the track lengths and comparator outputs for each track you're overwriting.

Resource Pack Generator

If manually converting mp3s and hand-editing JSON isn't your idea of a fun time, this project provides an alternative in the form of a stand-alone and portable (read: no installation or setup required) resource pack generator.

Installation

Download the executable from the release page that matches your operating system and your version of the mod.
Depending on your operating system and security settings, you may need to explicitly make the resource pack generator executable (on *nix systems, you can do this from a terminal by running chmod u+x /path/to/FoxNapRPG or by going into Properties in most file managers).

You can also build the generator from source.

Generating Resource and Data Packs

Place the generator executable in an empty folder, then move any music you want to turn into records into that folder. There is no limit to the number of tracks you can include, and they do not need to be pre-converted to Ogg. The only requirement is that the files have to be decodable by ffmpeg.

Pro Tip: if your music files include metadata, the title and artist name will get automatically extracted, and any album art will be used to help generate the music disc texture.

When you're ready, simply double-click the FoxNapRPG executable. A terminal window may pop up showing progress of the resource pack creation, and before you know it you should have some new files in your current directory:

FoxNapRP.zip is the resource pack containing all your converted songs and music disc textures, and you can throw that into your Minecraft resourcepacks folder
FoxNapDP.zip is the datapack that defines all the properties of the tracks themselves. You'll need to put this pack into the datapacks folder of any world where you want to use your music (see note below about multiplayer).
foxnap.yaml needs to go into your Minecraft config folder. This tells the game how many music discs to enable for you.

Advanced Options: Command-Line Options

You can also run the generator from the command-line, which will give you access to a bunch of additional customization options, such as setting the directories to search for music or the locations the generated resource pack and mod config should be saved.

For further details, run:

$ ./FoxNapRPG --help

from the folder where you saved the generator executable.

Advanced Options: Spec File

The Resource Pack Generator also allows you to finely tune the resource pack generation behavior via a configuration file. The pack generator currently supports the following formats:

INI (.ini, .cfg, .config, .conf, .txt)
JSON (.json)
CSV (.csv, .tsv) where each entry specifies a single track via either its full path or its file name.

For each track, you can specify:

num: a track number (to override the tracks bundled with the mod or just to make sure the tracks are ordered consistently)
description: the name to give to the track (if you don't want this read from the ID3 tag)
hue: the color to give to the vinyl part of the record template
use_album_art: whether the album art (embedded in the track tag data) for the inlay

To use a spec configuration file when running the resource pack generator, use the -s command-line flag, e.g.

$ ./FoxNapRPG -i /path/to/my/music -s track_specs.csv

What About Multiplayer?

When playing on a server, it's the server's datapacks and config file that will dictate:

how long each song will play
the redstone signal strength coming out of jukeboxes playing each disc
the number of tracks available from the Maestro

but it's each player's resource pack and config file that will control:

the songs that each disc will play
the appearance (and description) of each disc
which discs show up as "placeholder" records

Explicitly:

if the server has a greater number of discs specified than both what you've specified in your config, some discs will show up for you with placeholder textures and sound files
if you have more discs in your resource pack than are set on the server, then not all tracks will be available in your shared game
some music discs may continue silently after a song ends, and some might cut off

Beyond the number of discs, though, there's no reason why every player can't come online with a completely custom playlist of songs with similar lengths!

Obtaining Records and More!

So now that you've registered these custom records to the game, how do you actually get them? Outside of commands (e.g. /give @s foxnap:track_1) and Creative Mode, the sole way to obtain FoxNap records is by trading with The Maestro, a new villager who has a Jukebox as a job site (note that The Maestro does not currently spawn naturally, but this feature is planned).

The Maestro will pay top dollar for tonewood--stripped blocks of rare wood types--goat horns and non-FoxNap records and sells, alongside your custom music discs, a wide variety of playable musical instruments (with textures adopted from the classic mxTune mod).

Disabling The Maestro

If you'd prefer not to add The Maestro to your game (and would like to obtain your music discs in some other way, such as a datapack), you can disable this part of the mod by editing your foxnap.yaml config file and adding the following line:

enable_maestro: false

Building the Mod from Source

Clone this repo
Download and install a Java 21 OpenJDK such as Temurin
From the root of this repo, run ./gradlew build or load this project into your favorite Java IDE and run the "build" gradle task

The compiled jar will be found under build/libs.

Building the Resource Pack Generator from Source

You can also build the generator from source.

Clone this repo
Download or install a version of ffmpeg that can decode files from your music library and that has support for encoding using libvorbis. Put the executable (or symbolic links to the executable) in the foxnap_rpg/bin folder.
Create and activate a virtual environment using python 3.10 or above
1. If you have a conda-based environment and package manager installed on your system, such as mambaforge, you can use the project's dedicated dev/build environment, creatable from the repo root via mamba env create -f environment.yml (substitute conda for mamba as needed)
From the repo's root, with your virtual environment activated, run python -m pip install .
At this point, you have two options:
1. Use FoxNap as a python package, with $ FoxNapRPG available from the command line
2. Create a stand-alone executable using pyinstaller ( included in the conda environment). The scripts ./rpg-build.sh for *nix or .\rpg-build.bat for Windows are available for reference.

Fox Nap Vanilla

With the release of Minecraft 1.21, music discs are now entirely data-driven! As such, the resource and datapacks generated by the Fox Nap Resource Pack Generator are entirely compatible with the vanilla game. Details can be found on the wiki.

Many thanks to @FoundationGames for making the code of his awesome Sandwichable mod so easy to understand and learn from, and similarly to Modding by Kaupenjoe for his awesome and detailed tutorials on Minecraft modding, in this case his tutorial for adding a custom villager profession.

Also shouting out @Siphalor and Reddit's jSdCool for this conversation on adding non-mod external libraries to a Fabric mod. It should not have been this hard to add the SnakeYAML library to a mod.
