Worlds: Multiverse for Fabric

<a href="https://pixly.gg/?utm_source=modrinth&utm_medium=referral&utm_campaign=mc-worlds&utm_content=mods-banner">

Worlds lets a Fabric server run as many worlds as it wants, the way Multiverse does on Paper. Create, list, delete and teleport between worlds with in-game commands, and give each one its own time, weather and game rules. Every world plays like real vanilla Minecraft, down to the End dragon, which also makes Worlds a base other mods build their dimensions on. Worlds from World Manager or Multiworld can be recreated with one command each.

World types

/worlds create <id> makes an Overworld. Add from-preset for flat, amplified or any data pack preset, or from-dimension for a Nether, an End or any dimension type. /worlds tp takes you there.

• The End dragon fight, portals, maps and ender pearls work in every world you create, not only in the original three.
• Own weather and time. Vanilla /weather and /time run inside a world change only that world.
• Own game rules. Keep inventory, PvP, mob spawning, daylight and more, set with vanilla /gamerule inside the world. Rules you leave alone follow the server, and /gamerule <rule> inherit hands one back. With Worlds installed on the client, the Game Rules screen shows which rules the world changed.
• Nothing new to learn. No extra commands for weather, time or rules, and the Overworld, Nether and End behave exactly as in vanilla.

• Load on demand. A world loads when a player enters it and unloads a minute after the last player leaves, so you can keep hundreds of worlds without paying for idle ones.
• Updated within a week of each Minecraft release. Worlds follows the newest Minecraft version; older versions stay on the Versions tab.
• A base for other mods. Mods register their own world types through the Worlds API and let Worlds handle creating, loading, saving and teleporting. Stargate is built on it; API.md has the guide and the Gradle setup.

| Command | What it does | |---|---| | /worlds create <id> [seed] | Creates an overworld | | /worlds create <id> from-preset <preset> [dimension] [seed] | Creates a world from a world preset, for example minecraft:flat or minecraft:amplified | | /worlds create <id> from-dimension <type> [seed] | Creates a world of a dimension type, for example minecraft:the_nether or minecraft:the_end | | /worlds import <id> <save> [<dimension>\|all] | Imports a singleplayer world, another server's worlds (Paper and Multiverse too), a zip, or a direct download link to a zip | | /worlds tp <id> [players] | Teleports you or other players to a world's spawn | | /worlds list [loaded\|unloaded] | Lists worlds; hover for details, click to teleport | | /worlds delete <id> | Deletes a world after moving everyone out of it | | /worlds settings spawn [here\|<x> <y> <z>] | Shows or sets the spawn of the world you are in | | /worlds settings loadOnStartup [true\|false] | Shows or sets whether the world you are in loads when the server starts | | /gamerule <rule> <value> | In a created world, sets a rule for that world only | | /gamerule | In a created world, lists the rules the world changed | | /gamerule <rule> inherit | In a created world, makes a rule follow the server again |

A world id without a namespace gets minecraft:, so /worlds create mining creates minecraft:mining. Run any command for another world with /execute in <world> run .... /worlds commands need operator level 3; /gamerule needs level 2, as in vanilla.
