# WorldManager Create, load, unload, delete, back up, restore, teleport between, and pre-generate Minecraft worlds — all from one command, with a native in-game menu. No chest-GUI hacks: as of **3.0.0**, every menu screen is built on Minecraft's own **Dialog** UI. > Report bugs or suggest features on [GitHub Issues](https://github.com/Mathildeuh/WorldManager/issues). ## Features - **World management** — create (normal, flat, large biomes, amplified, nether, the end, or a custom generator), load existing world folders, unload, and permanently delete worlds. - **Backups** — zip a world's folder on demand and restore it later, with the heavy I/O kept off the main thread so it doesn't freeze the server. - **Pre-generation** — generate chunks in a bounded radius around a center point ahead of time, with start/pause/resume/stop control and a boss-bar progress indicator. Multiple worlds can pre-generate concurrently. - **Teleportation** — jump yourself or another player straight to a world's spawn. - **Game rules** — browse and edit every `GameRule` supported by a world, per-world, without touching `bukkit.yml` or server commands. - **Linked-worlds inventories** *(optional)* — group worlds together so players keep one shared inventory across the group, and get a clean slate (or their group's saved inventory) when they leave it. Backed by SQLite or MySQL/MariaDB. - **Linked Nether/End portals** *(optional)* — point a world's Nether/End portals at specific worlds instead of Bukkit's auto-derived `_nether`/`_the_end` pair, e.g. send `TEST`'s portals to `Nether_TEST`/`End_TEST`. Both directions are handled automatically. - **In-game dialog UI** — `/wm gui` opens a native Dialog menu: create a world through a single form (name, type, seed, generator, empty-world toggle), browse and manage loaded worlds, edit game rules with real sliders and toggles, and confirm destructive actions (delete/unload/ restore) through a proper Yes/No dialog — no more "type in chat, don't type cancel." - **PlaceholderAPI support** — `%worldmanager_current_world%`, `%worldmanager_loaded%`, `%worldmanager_total_player_amount%`, and more. - **Six languages out of the box** — English, French, Spanish, German, Polish, Russian. Every player-facing message is defined in a lang file, not hardcoded. ## Commands All commands are under `/worldmanager` (alias `/wm`). | Command | Description | |---|---| | `/wm` or `/wm gui` | Open the main Dialog menu | | `/wm create [type] [seed] [generator]` | Create a new world | | `/wm load [dimension] [generator]` | Load an existing world folder | | `/wm unload ` | Unload a world | | `/wm delete ` | Permanently delete a world | | `/wm backup ` | Back up a world | | `/wm restore ` | Restore a world from its latest backup | | `/wm teleport [player]` | Teleport yourself or another player to a world | | `/wm pregen [center:x,z] [radius:n]` | Control world pre-generation | | `/wm list` | List currently loaded worlds | ## Permissions | Permission | Grants | |---|---| | `worldmanager.command` | Base access to `/worldmanager` | | `worldmanager.gui` | Open the Dialog menu | | `worldmanager.create` | Create worlds | | `worldmanager.load` | Load worlds | | `worldmanager.unload` | Unload worlds | | `worldmanager.delete` | Delete worlds | | `worldmanager.backup` | Back up worlds | | `worldmanager.restore` | Restore worlds | | `worldmanager.teleport` | Teleport between worlds | | `worldmanager.pregen` | Control pre-generation | | `worldmanager.list` | List loaded worlds | ## Supported versions **Paper 1.21.7 → 26.2.** Dialogs first shipped client-side in Minecraft 1.21.6 and became available to plugins in Paper 1.21.7 — WorldManager 3.0.0 targets that as its floor so the Dialog UI works everywhere it possibly can, while staying current with the latest release. Spigot/CraftBukkit are **not** supported from 3.0.0 onward — the Dialog API is Paper-exclusive, which is why this plugin is distributed on Hangar (Paper's own platform) as a primary channel. ## What's new in 3.0.0 - **Critical fix**: a bug (present since 2.2.0) where players could lose their inventory when changing worlds even with linked-worlds-inventory *disabled*, or between two worlds neither of which was in a configured group. If you saw inventory loss after updating to 2.2.x, this is why — see [`AUDIT.md`](https://github.com/Mathildeuh/WorldManager/blob/master/AUDIT.md) for details. - New: linked Nether/End portals (see Features above). - Entire GUI rebuilt from scratch on the Dialog API, replacing the old chest-inventory menus. - World creation is now a single form instead of a multi-step chat-capture flow. - Integer game rules are edited with a proper slider instead of ±1 buttons or typing in chat. - Numerous other correctness and reliability fixes: main-thread-blocking I/O moved off the main thread (backups, the update checker, join-time release-note fetch), a bug where custom generators passed to `/wm load` were silently ignored, a double-teleport bug on `/wm unload`, and "success" messages that could fire before the underlying async work actually finished. Full details in [`AUDIT.md`](https://github.com/Mathildeuh/WorldManager/blob/master/AUDIT.md). ## Configuration ```yaml lang: en # en, fr, es, de, pl, ru database: type: sqlite # or mysql enable-linked-inventory: false linked-worlds-inventory: group1: - world - world_nether linked-portals: TEST: nether: Nether_TEST end: End_TEST ``` ## Links - [Source & issue tracker](https://github.com/Mathildeuh/WorldManager) - [Modrinth](https://modrinth.com/plugin/easy-worldmanager) - [CurseForge](https://www.curseforge.com/minecraft/bukkit-plugins/easy-worldmanager) - [SpigotMC resource page](https://www.spigotmc.org/resources/worldmanager.117043/)
