Play multiple characters in one world! Opt-in, customizable player profiles for hotseat multiplayer, lets plays, plural systems, RP servers, or just for fun!
Serverside player profiles for hotseat multiplayer, adventure maps, and plural systems.Disclaimer: All mods that manipulate player data have a save corruption risk!
Always take backups of your worlds, especially when updating mods.
Switchy allows players to create profiles, which have their own partial player data, and can be switched between.
Profile data is defined by player-toggleable components, including:
This means you can adjust profiles to only contain some of the above, e.g. just nicknames, skins, and origins.
Just run /switchy and follow the hints! This covers renaming, toggling components, and making new profiles.
After this, you can freely switch profiles via /switch <name> or by clicking <switch> in the profile list.
Switching into a profile restores component data to the state it was in was when you last switched out of that profile.
So to change e.g. a fabric tailor skin for a profile, switch into the profile first, then set the skin as you normally would.
Profiles are per-world, so speed things up by running /switchy export to get your name/skin data to save to a .json file.
To import, upload the file (e.g. to tmpfiles.org) and paste the link into /switchy import all <url>.
You can also import from PK (and import from / export to Utter) - use /switchy import <member/group> to filter imports.
Switchy can be used to switch modded data in a modpack by setting up switchy components in a datapack:
// data/minecraft/switchy_components/inventory/ender_chest.json (minecraft:inventory/ender_chest)
{
"enabled": true, // whether to load the component at all. use this instead of deleting default files, as they'll regenerate.
"codec": "inventory", // which codec (from the registry in SwitchyComponentTypes) to use to deserialize the data. defaults to "nbt" (passthrough)
"path": "EnderItems", // NBT path targeting the part of player.dat to load from / modify to
"preview": "inventory", // which text previewer (from the registry in SwitchyComponentTypes) to use in chat. null = toString(), use "trunc" for long data. Start with $ to use an NBT path for passthrough components.
"prefix": "👁 ", // a prefix to add to the text preview, for glanceability
"emptyChecker": "inventory", // which empty checker (from the registry in SwitchyComponentTypes) to use to prevent profile deletion for precious data. Start with $ to use an NBT path for passthrough components.
"group": "inventory", // components with a matching group ID will be previewed and toggled as if they're one component
"default": [], // default value. JSON serialized. set to "$copy" to copy the value from previous. set to null or omit to delete the key from player data as the initial value.
"hidden": false // hides the component preview in the profiles list (still shown in the components list)
}
Feel free to browse the included components for examples.
You're welcome to PR datapack components (with load conditions), along with any additional previewers etc.
Switching data outside player NBT requires an addon. API TBD - Interested addon devs can hit up the issues page.
If you're a plural system (or a friend to one) and appreciate our work, please consider reading and sharing sys.guide, our plurality handbook.
Switchy was our first original minecraft mod, made during the mod jam ModFest: Singularity.
Since making it, the minecraft modding community has given us friendship, mentorship,
endless favours, an outlet for self-expression, and reinforced our passion for software as an art.
Everyone who's been a part of that - and you should know who you are - thank you.
