SongPlayer

A Fabric mod for Minecraft that plays songs with noteblocks. The current version is for Minecraft 1.21

How to install

You can grab the mod jar from releases section. This mod requires fabric api.

Adding songs

You can put midis or NoteBlockStudio files in the .minecraft/songs folder. SongPlayer supports any valid midi and all versions of NBS files.

Using the client

To get started, add some midis or nbs files to your songs folder, and use $play <filename> in an open area. Spaces are not supported in filenames or filepaths. If you have provided it a valid midi or nbs file, it will try to set your gamemode to creative, place the required noteblocks for the song, try to switch you to survival, then start playing.

You can also organize songs into subdirectories in your songs folder. Tab completion will make it easy to navigate. Symlinked directories are supported too.

Commands

All the commands are case insensitive.

$help

$help <command>

If no arguments are given, lists all SongPlayer commands. Otherwise, explains the specified command and shows its syntax.

$setPrefix <prefix>

aliases: $prefix

Sets the prefix used for all SongPlayer commands (by default: $)

$play <filename or url>

Plays a particular midi from the .minecraft/songs folder, or, if a url is specified, downloads the song at that url and tries to play it.

If there is a song already playing, the new song will be added to the queue.

$stop

Stops playing/building and clears the queue.

$skip

Skips the current song and goes to the next one.

$goto <mm:ss>

Goes to a specific time in the song.

$loop

Toggles song looping.

$status

aliases: $current

Gets the status of the current song that is playing.

$queue

aliases: $showqueue

Shows all the songs in the queue.

$songs

$songs <subdirectory>

aliases: $list

If no arguments are given, lists songs in the songs folder. Otherwise, lists songs in the specified subdirectory.

$playlist play <playlist>

$playlist create <playlist>

$playlist list [<playlist>]

$playlist delete <playlist> <song>

$playlist addSong <playlist> <song>

$playlist removeSong <playlist> <song>

$playlist renameSong <playlist> <old name> <new name>

$playlist loop

$playlist shuffle

$setCreativeCommand <command>

aliases: $sc

By default, the client uses /gmc to go into creative mode. However, /gmc does not work on all servers. If the creative command is different, set it with this command. For example, if the server uses vanilla commands, do $setCreativeCommand /gamemode creative.

$setSurvivalCommand <command>

aliases: $ss

By default, the client uses /gms to go into survival mode. However, /gms does not work on all servers. If the survival command is different, set it with this command. For example, if the server uses vanilla commands, do $setSurvivalCommand /gamemode survival.

$useEssentialsCommands

aliases: $essentials, $useEssentials, $essentialsCommands

Switch to using Essentials gamemode commands.

Equivalent to $setCreativeCommand /gmc and $setSurvivalCommand /gms

$useVanillaCommands

$aliases: $vanilla, $useVanilla, $vanillaCommands

Switch to using vanilla gamemode commands.

Equivalent to $setCreativeCommand /gamemode creative and $setSurvivalCommand /gamemode survival

$toggleFakePlayer

aliases: $fakePlayer, $fp

Toggles whether a fake player will show up to represent your true position while playing a song. When playing a song, since it automatically enables freecam, your true position will be different from your apparent position. The fake player will show where you actually are. By default, this is disabled.

$setStageType <DEFAULT | WIDE | SPHERICAL>

aliases: $setStage, $stageType

Sets the type of noteblock stage to build. Thanks Sk8kman and Lizard16 for the spherical stage design!

• Default: A square shaped stage with a maximum of 300 noteblocks
• Wide: A cylindrical stage with a maximum of 360 noteblocks
• Spherical: A densely packed spherical stage that can contain all 400 possible noteblocks

$toggleMovement <swing | rotate>

aliases: $movement

Toggles whether you swing your arm when hitting a noteblock and rotate to look at the noteblocks you are hitting.

$setVelocityThreshold

aliases: $velocityThreshold $threshold

Sets the minimum velocity below which notes won't be played (applies to midi and nbs). This must be a number from 0 to 100. For song items, the threshold is baked in upon item creation.

$toggleAutoCleanup

aliases: $autoCleanup

Toggles whether you automatically clean up your stage and restore the original blocks after playing.

$cleanupLastStage

Cleans up the most recent stage that you made and does its best to restore the blocks to their original state.

If you stop playing and start playing again, the recorded modifications gets reset.

Will not replace fluids or double blocks such as doors, and does not replace tile entity data. May not properly handle blocks that rest on other blocks such as torches, either.

$announcement <enable | disable | getMessage>

$announcement setMessage

Set an announcement message that is sent when you start playing a song. With setMessage, write [name] where the song name should go.

Example: $announcement setMessage &6Now playing: &3[name]

$songItem create <song or url>

$songItem setSongName <name>

aliases: $item

Encodes song data into an item. When you right click on such an item, SongPlayer will automatically detect that it is a song item and ask if you want to play it. These items, once created, can be used by anyone that is using the necessary version of SongPlayer.

It will automatically generate custom item names and lore, but these can be modified or deleted without affecting the song data, so feel free to edit the items as you wish. SongPlayer only looks at the SongItemData tag.

$toggleSurvivalOnly

aliases: $survivalOnly

Enables or disables survival-only mode, in which automatic noteblock placement is disabled and automatic tuning is done by right-clicking.

In this mode, you must place the necessary instruments yourself.

If you try to play a song and the requirements are not met, it will tell you how many instruments of each type you need.

$testSong

A command I used for testing during development. It plays all 400 possible noteblock sounds in order.

Mechanism

SongPlayer places noteblocks with nbt and instrument data already in them, so the noteblocks do not need to be individually tuned.

The client will automatically detect what noteblocks are needed and place them automatically before each song is played, which makes playing songs quite easy. The only drawback is that you need to be able to switch between creative and survival mode, which my client will attempt to do automatically.

When playing a song, freecam is enabled. You will be able to move around freely, but in reality you are only moving your camera while your player stays at the center of the noteblocks. This is because noteblocks can only be played if you're within reach distance of them, so you have to stand at the center of the noteblocks to play them, but it's still nice to be able to move around while your song is playing.

Acknowledgements

Ayunami2000: Came up with the concept of directly placing noteblocks with nbt data instead of manually tuning them.

Sk8kman: Several of Songplayer 3.0's changes were inspired by their fork of SongPlayer. Most notably was their alternate stage designs, but it also motivated me to implement playlists and togglable movements.

Lizard16: Cited by Sk8kman as the person who made the spherical stage design.
