? AltWorlds: Your Universe, Your Rules
-green?style=for-the-badge)
AltWorlds redefines personal world management. Forget about complex, heavy database systems. This is a professional, lightweight, and fully GUI-based plugin that allows every player to create, manage, and moderate their own "mini-universes" within your server.
From private Survival worlds to collaborative Creative plots, including Custom Templates. Everything is managed through an intuitive graphical interface, optimized for modern servers.
? Why choose AltWorlds?
? 100% GUI Experience
Your players don't need to memorize commands.
- Wizard-Style Creation: Choose type, generator, and name step-by-step.
- Icon Selector: Players can pick the icon for their world (blocks/items) directly from a paginated menu.
- In-Game Menu Editor: Are you an admin? Edit the main menu icons directly in-game (Shift+Click in edit mode).
?️ Deep World Management
It's not just about "creating a world." It's about managing it.
- Hierarchical Roles:
OWNER, ADMIN, MEMBER, VISITOR.
- Self-Moderation: Owners can invite, kick, and ban (Temp/Perm) users from their own worlds.
- On-the-fly Toggles: Enable/disable PvP, Flight, Hunger, Weather, FireTick, Spawning, and more with a single click.
⚡ Smart Performance ("The Janitor")
Built on a robust Lifecycle System:
- Auto-Unload: Empty worlds are automatically unloaded from RAM after a configurable cooldown.
- Session Locking: Prevents corruption during load/unload cycles or rapid teleports.
- No Database: Everything is stored in clean, portable YAML files (
/data/players/). Backup and transfer folders with ease.
?️ Flexible World Types
- Vanilla: Classic Survival experience.
- Creative: With Flat or Void (Skyblock style) generator options.
- Templates: Create folders with schematics or pre-built maps and let players clone them.
- Auto-Worlds: Automatically assign specific worlds to players (ideal for plot servers or storylines).
? Detailed Features
? Social System
- World Explorer: List public worlds sorted by Likes, Visits, Online Players, or Type.
- Like System: Let players vote for their favorite worlds!
- Invites: Secure invitation system for private worlds.
? Lobby & Home
- Central Lobby: Configure a world as the Lobby. Includes a configurable inventory item to open the menu.
- Auto-Join Home: Players can set their favorite world to join directly upon login, skipping the lobby.
?️ Administration (Server Worlds)
AltWorlds isn't just for players. As an admin, you can register "Server Worlds" (Lobbies, Spawns, RPG maps) so they appear in menus, have their own rules, and benefit from the optimized teleportation system.
? Commands & Permissions
The plugin is designed to be GUI-first, but includes powerful commands for power users.
