AstralBot

This is a Minecraft mod and Discord Bot in one package. It's intended for the Create: Astral Modpack's official server, but it's implemented cross-platform to be usable by others too. The goal is to be easy-to-use and accessible for non-technical server admins, while allowing true complexity for power users.

Features

These features are the core of what this bot will do. See the Status section to see how much is already implemented.

Discord and Minecraft account linking, optionally requiring this to be whitelisted
Discord and Minecraft chat synchronization
FAQ commands using Markdown files without needing to restart the server

Dependencies

This mod has a few dependencies, some of which are not specified directly as they're technically optional:

The Kotlin Implementation for the platform you're running. (e.g. Kotlin For Forge or Fabric Language Kotlin)
The (Neo-)Forge Config API (Included in NeoForge, extra mod for Fabric)

Implementation

JDA library to communicate with the Discord API.
Kotlin for the improved development experience over Java
Architectury for multiplatform development
JetBrains Exposed to communicate with the Database

Configuration

The following things will be configurable:

Required linking to be whitelisted (default: off)
Chat synchronization with imitated Discord Users:
1. No user imitation (The bot will write the messages under its own name)
2. (If possible) Minecraft user imitation (The Minecraft usernames and heads will be used for messages)
3. (Only available if requiring linking for whitelist) Discord user imitation (The messages will be written under the linked Discord name)
Default: No user imitation
Managing FAQs through a command interface (default: off)
Database connection. Uses an SQLite database by default

Status

Running

There is no public instance of this bot/mod available. To use it, create a new Application on the Discord Developer Portal and configure it to have the three privileged gateway intents: PRESENCE, SERVER MEMBERS and MESSAGE CONTENT.

Copy the bot token and store it somewhere safe (like a Password Manager) and never show it to anybody else. To make sure the token gets read by the bot, it has to be in an Environment Variable DISCORD_TOKEN where the running Minecraft server can access it. You could for example modify a start.sh script on a Unix-like system to export it or start the shell script with it set directly:

startmc.sh:

export DISCORD_TOKEN=<place token here>

java ... # java command that starts the server

DISCORD_TOKEN=<place token here> startmc.sh # Start the script with the env variable set

After starting the server, you can go into the OAuth2 URL builder on the Discord Developer Portal and generate a URL with the bot and applications.command permissions. Use the generated URL to have the bot join your server.
