MLobbySystem

A modern, lightweight lobby system for Paper servers — built with performance and flexibility in mind. Designed for current server setups, including full support for Folia's regionized multithreading model.

✨ Features

• ⚡ Folia Support – Built to run safely and efficiently on Folia servers
• 🧭 Custom Spawn System – Define and manage your lobby spawn with ease
• 🎮 Join Management – Custom or silenced join/quit messages, teleport-on-join/respawn/void
• 🧰 Modular Hotbar Items – Add, remove, or reskin as many hotbar items as you want, each with its own action: show links, open the server selector, toggle player visibility, run a command, open the cosmetics menu, or send a rich clickable chat message
• 💬 Clickable Chat Messages – The show-text item action sends multi-line MiniMessage text with per-line click behavior (open URL, run command, suggest command, copy to clipboard) and a {player} placeholder
• 🎩 Cosmetics – Hats, particle trails, and gadgets (firework burst, grappling hook, pearl bow), each optionally permission-gated and persisted per player across restarts
• 🖥️ Server Selector Menu – Paginated, MiniMessage-styled proxy server selector
• 🚫 Lobby Protection – Disable damage, hunger, block breaking, and more
• 🔄 Auto Teleport – Send players to spawn automatically on join, respawn, or void fall
• 🔌 Scriptable – Every hotbar item use fires a cancellable LobbyItemUseEvent, so other plugins or scripts (e.g. Skript) can react to or override item behavior
• 🎛️ Highly Configurable – Simple config structure for fast setup and customization

🧩 Compatibility

• ✅ Paper 1.21.11, 26.1.x, 26.2 (Java 21+ for the plugin; Paper itself needs Java 25 to run its 26.x builds)
• ✅ Folia (same version range) - built against the shared Paper/Folia API, Folia builds exist for the same versions

The plugin is built once against the oldest supported API and verified by booting the same jar against real Paper 1.21.11, 26.1.2, and 26.2 servers - no separate builds per Minecraft version needed.

🚀 Why MLobbySystem?

MLobbySystem focuses on modern server architecture: commands are registered through Paper's Brigadier command API (real tab-completion, no legacy CommandExecutor), config is loaded into typed, immutable records instead of scattered mutable fields, and every menu is built on a small reusable click-handler framework rather than one-off PersistentDataContainer tags. It avoids outdated sync-heavy logic and stays compatible with next-generation platforms like Folia.

📦 Installation

1. Download the latest release
2. Place the .jar file into your /plugins folder
3. Restart your server
4. Configure the plugin in the generated config files

⚙️ Configuration

All features are configurable via config.yml and messages.yml. Every message supports MiniMessage formatting (gradients, hex colors, etc.).

Hotbar items (hotbar.items) and cosmetics (cosmetics.items) are both free-form lists — add as many as you want, each keyed by a unique id you choose. Both files ship with commented examples covering every available action/kind.

🕹️ Commands

Commands you don't have permission for won't show up in tab-completion at all — this is standard Brigadier permission-gating, not a bug.
