AnnouncementGUI v1.1

AnnouncementGUI is a Paper plugin that lets server owners and staff create, edit, schedule, and broadcast clean announcement panels directly from an in-game inventory GUI.

Instead of using plain chat broadcasts, AnnouncementGUI displays structured announcement panels with title, description, body text, colors, placeholders, and optional centered lines.

Features

• In-game announcement management GUI
• Create, edit, delete, and toggle announcements
• Scheduled automatic broadcasts
• Manual force-broadcast command
• Clean panel-style announcement format
• Title, description, and body layout
• Legacy color code support such as &a, &b, &6
• Hex color support such as &#55FFFF
• Placeholder support
• Per-line body centering with <center>text</center>
• Target announcements to LOCAL, SERVER, SERVERS, GROUP, or GLOBAL
• Optional Redis Pub/Sub sync for multi-server networks
• YAML-based local storage
• Configurable GUI titles and panel formatting

Why Use AnnouncementGUI?

AnnouncementGUI is designed for server owners who want a cleaner and easier way to manage server announcements.

Staff can manage announcements without manually editing config files every time. Announcements can be created through a GUI, saved to storage, scheduled, and broadcast to the correct server or network target.

It is useful for:

• Lobby networks
• Survival servers
• Minigame networks
• Community servers
• Staff-managed announcement systems
• Networks that need Redis-based cross-server sync

Permissions


Requirements

• Paper 1.21.x
• Java 21
• Redis is optional and only required for cross-server sync

Storage and Sync

AnnouncementGUI currently uses local YAML storage for announcements.

Redis sync is available for multi-server setups. It is used to publish announcement changes between servers, such as create, update, delete, and force-broadcast events.

Note: Redis sync is event-based. It is not a shared SQL database system.

Configuration

The plugin includes a configurable config.yml file where you can set:

• Server id
• Server groups
• Storage file
• Redis URI and channel
• Scheduler check interval
• Panel borders and separators
• GUI inventory titles

Good For Networks

Each server can have its own server id and groups, for example:


This allows announcements to target one server, a group of servers, or the entire network.
