Latest version, with the Minecraft version it runs on

**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. Creating worlds

Typing /worlds create event_end from-dimension minecraft:the_end, then /worlds tp event_end, and arriving in a new End under the circling Ender Dragon

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 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. Performance and API

- **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](https://modrinth.com/mod/mc-stargate) is built on it; [API.md](https://github.com/Wroud/mc-worlds/blob/main/API.md) has the guide and the Gradle setup. Commands

| Command | What it does | |---|---| | `/worlds create [seed]` | Creates an overworld | | `/worlds create from-preset [dimension] [seed]` | Creates a world from a world preset, for example `minecraft:flat` or `minecraft:amplified` | | `/worlds create from-dimension [seed]` | Creates a world of a dimension type, for example `minecraft:the_nether` or `minecraft:the_end` | | `/worlds tp [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 ` | Deletes a world after moving everyone out of it | | `/worlds settings spawn [here\| ]` | 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 ` | In a created world, sets a rule for that world only | | `/gamerule` | In a created world, lists the rules the world changed | | `/gamerule 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 run ...`. `/worlds` commands need operator level 3; `/gamerule` needs level 2, as in vanilla. Examples

**A resource world you can reset** ``` /worlds create mining /worlds tp mining /worlds delete mining /worlds create mining ``` **A creative build world with no mobs and endless daylight** ``` /worlds create build from-preset minecraft:flat /worlds tp build /gamerule spawn_mobs false /gamerule advance_time false /gamerule advance_weather false ``` **A safe lobby where new players spawn** ``` /worlds create lobby /worlds tp lobby /setworldspawn /gamerule pvp false /gamerule spawn_monsters false ``` **Keep inventory only in an arena** ``` /execute in minecraft:arena run gamerule keep_inventory true ``` **Moving from World Manager or Multiworld:** replace it with Worlds, then run `/worlds create from-dimension ` with the id, type and seed each world had. Classic Overworld, Nether and End worlds are supported. ## Requirements - Minecraft 26.3 - Fabric Loader 0.18.4+ and Fabric API - Java 25 ## Recent updates - **1.10.0** Per-world game rules through vanilla `/gamerule`, and a fix for a rare "Exception generating new chunk" crash when several worlds generate structures at once. - **1.9.0** `/worlds list` with loaded and unloaded worlds, hover details and click-to-teleport. - **1.8.26** A world that holds the world spawn stays loaded, and deleting it moves the spawn back to the Overworld.
