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.

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.
• 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).

Permissions

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.

What's new in 3.0.0

• 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 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.
