TeleFabric

A Fabric mod that bridges your Minecraft server with a Telegram group.

Features

• Chat Bridging: Forward in-game chat to your Telegram group and relay messages from Telegram back to the Minecraft server.
• Remote Commands: Execute server commands (e.g., /list, /whitelist) directly from Telegram with a flexible permission system.
• Player Notifications: Broadcast player join, leave, and death notifications to your Telegram chat.

Build

./gradlew build

Setup Guide

Follow these steps to get TeleFabric up and running.

1. Create a Telegram Bot

1. Open Telegram and send a direct message to @BotFather.
2. Send the /newbot command and follow the on-screen instructions.
   • Note: Pay attention to the distinction between the bot's name and username. You will need the username later.

• Once the bot is created, copy the bot token provided by BotFather.
• Add your new bot to the Telegram group you want to link.

2. Install the Mod

1. Download the latest .jar file from the Releases page.
2. Place the .jar file into your server's mods directory (/path/to/server/mods/).

3. Initial Configuration

1. Start your server once to generate the configuration file.
2. Stop the server.
3. Open and edit the new file at /path/to/server/config/telefabric.yml.
4. Fill in the bot_token and bot_username fields with the credentials you received from BotFather.

4. Get Your Chat & User IDs

1. Start your server again. The bot should now be online.
2. In the Telegram group where you added the bot, type the command /getid.
3. The bot will reply with the Chat ID and your personal User ID. Copy these values.
   • Important: Group Chat IDs start with a hyphen (-). Don't forget to include it.

5. Finalize Configuration

1. Stop the server and open telefabric.yml again.

2. Add the Chat ID(s) and admin User ID(s) to the appropriate fields.

   # A list of chat IDs the bot will listen to and broadcast messages to.
   chats: [-100123456789, -1145141919810] # <-- Replace with your Chat ID(s)
   
   features:
     # ...
     bot_cmd_command:
       enabled: true
       commands:
         whitelist:
           # A list of user IDs allowed to execute this command from Telegram.
           allowed_users: [123456789] # <-- Replace with an admin's User ID
           permission: users
         # ...
     # ...
   

3. Save the file and start your server. The bridge is now fully configured!

4. If you need to apply changes later without restarting the server, you can use the /telefabric reload command in the server console.

Troubleshooting

Incorrect Bot Settings

• Symptom: The bot responds to commands (like /getid) in a direct message but ignores all commands in the group chat.
• Solution: This is likely due to the bot's privacy settings.
  1. DM @BotFather and send the /mybots command.
  2. Select your bot from the list.
  3. Navigate to Bot Settings -> Group Privacy.
  4. Ensure that group privacy is turned OFF. When disabled, the bot can receive all messages sent in the group.

Acknowledgements

This project was created in memory of a fellow developer.

While searching for a Fabric-Telegram bridge mod for Minecraft 1.21.4, I came across CuteNekoOwO/FabricTgBridge. I was deeply saddened to learn that its creator, MeowBot233, had passed away, and the project would remain on version 1.20 forever. 🕯️

Inspired by their work, I decided to create a new mod with similar functionality for modern versions of Minecraft. And so, TeleFabric was born.
