WorldEaterNotifier

---

What is it?

Fabric mod that monitors world eaters (TNT-based), trenchers, and bedrock breakers (block destruction-based), sending Discord webhook notifications with per‑event ping control and fully customizable messages when they stop, start, or get obstructed.

Documentation

For a complete guide on how to configure all the features please visit the documentation: WorldEaterNotifier Documentation

Features

• Real-time monitoring: Tracks world eaters (TNT count), trenchers, and bedrock breakers (block destruction).
• Discord integration: Sends instant notifications when a machine starts, stops, resumes, or is manually stopped.
• Customizable messages: Every notification message is configurable per machine type via JSON — use {type} and {name} placeholders.
• Role-based notifications: Mention specific Discord roles with per‑event toggles (global, start, manual stop, stuck, resumed, server shutdown). All configurable in‑game via commands.
• Discord bot mode: JDA-powered bot with interactive toggle button and slash commands (/config, /worldeater start|stop|list, /trencher start|stop|list, /bedrockbreaker start|stop|list) with autocomplete.
• Configurable thresholds: Stop timeout, minimum TNT count / blocks broken per machine type.
• Multi-world support: Monitor machines across different dimensions.
• Persistent configuration: Machine definitions, settings, and ping toggles survive server restarts. Messages are editable in JSON.
• Server shutdown detection: Automatically stops all active machines on shutdown and notifies Discord.

Installation

1. Clone the repository:

   git clone https://github.com/CodeW4VE/WorldEaterNotifier.git
   cd WorldEaterNotifier
   

2. Build the mod:

   ./gradlew build
   

3. Copy the generated .jar file from build/libs/ to your server's mods folder:

   cp build/libs/worldeaternotifier-*.jar /path/to/server/mods/
   

4. Create a worldeaternotifier-config.json file in your server's config directory with Discord webhook and world eater settings.

Configuration

The mod creates config/worldeaternotifier.json on first run. You can edit it manually or use the in‑game commands.

}

• webhookUrl: Discord webhook URL.
• pingRoleId: ID of the Discord role to mention. Leave empty or "0" to disable all mentions.
• notificationMode: "webhook" (default) or "bot" — switches between webhook and JDA bot delivery.
• botToken: Discord bot token (required for bot mode).
• guildId / channelId: Discord guild and channel for bot notifications and slash commands.
• showSubscriptionButton: Whether to show the "Toggle Ping" button on start messages (bot mode).
• memberDiscordRole: Discord role ID that gates /worldeater start|stop|list (and trencher/bedrockbreaker equivalents) via slash commands; admins always have access.
• stopTimeoutSeconds: How many seconds without activity before the machine is considered stuck.
• minTntCount / minBlocksBroken: Minimum activity per check to keep the machine alive.
• pingSettings: Per-machine-type ping toggles (enabled, onStart, onStop, onStuck, onResumed, onShutdown) — these now persist across restarts.
• messages: Customizable Discord notification messages per machine type. Use {type} for the machine type name and {name} for the machine instance name.

Usage

1. Install the mod and start your server.
2. Configure delivery:
   • Webhook mode (default): /worldeater settings setWebhookUrl <url>
   • Bot mode: /worldeater settings setBotToken <token>, set setGuildId and setChannelId, then /worldeater settings setNotificationMode bot
3. Create machines:
   • /worldeater create <name> <x1> <y1> <z1> <x2> <y2> <z2>
   • /trencher create <name> <x1> <y1> <z1> <x2> <y2> <z2>
   • /bedrockbreaker create <name> <x1> <y1> <z1> <x2> <y2> <z2> (Coordinates auto‑suggest the block you stand on; Tab completes names.)
4. Start monitoring with /worldeater start <name>, /trencher start <name>, or /bedrockbreaker start <name>.
5. The mod automatically sends Discord messages when a machine stops unexpectedly (stuck), resumes, or is manually stopped.
6. In bot mode, Discord slash commands mirror the Minecraft commands:
   • /worldeater start <name>, /worldeater stop <name>, /worldeater list (autocomplete suggests existing names)
   • Same for /trencher and /bedrockbreaker
   • /config pings — interactive flow to toggle per-machine-type ping settings
7. Adjust settings on the fly:
   • /worldeater settings show, /trencher settings show, /bedrockbreaker settings show
   • /worldeater settings setStopTimeout <seconds>
   • /trencher settings setMinBlocksBroken <count>
   • /worldeater settings discordPings enable true and individual events like onStuck false
   • /worldeater settings showSubscriptionButton <true|false> (bot mode)
   • /worldeater settings setMemberDiscordRole <roleId> (bot mode)
   • Edit notification messages directly in the JSON file.
   • Use Tab to explore all subcommands.
8. Manage machines: list, stop, delete for all three types.
9. When the server shuts down, all active machines are stopped and a shutdown notification is sent.
