ZenithProxy

Minecraft proxy/bot intended for use on 2b2t.org.

Unlike a traditional MC bot, you can login to it as a normal MC server and control the account.

The primary purpose is to have accounts always online in-game and securely shared by multiple people.

This project is also used to support the 2b2t.vc API and Discord Bot.

What is a proxy?

This proxy itself consists of two components:
1. A Minecraft Server ("Proxy Server")
2. A Minecraft Client ("Proxy Client")

Players use a Minecraft client to connect to the Proxy Server as you would a normal MC server.
The Proxy Client connects to a destination MC server (i.e. 2b2t.org).
The Player's packets to the Proxy Server get forwarded to the Proxy Client which 
forwards them to the destination MC server.

Player MC Client -> Proxy Server -> Proxy Client -> MC Server

When no Player Client is connected the Proxy Client will act 
as a bot: moving around, chatting, etc.

How does it work?

ZenithProxy does not use, depend on, or interact with the Minecraft client or server code.
This means much greater opportunities for optimizing memory usage and performance.

But this also means existing MC mods or plugins cannot be used and must be
reimplemented specifically for ZenithProxy.

ZenithProxy acts primarily at the network packet layer. It can read/modify/cancel/send
arbitrary packets in either direction at any time.

Using packet interception, the client's session and world state is cached and 
sent to players when they connect.

The cached world state is also used to simulate player movements, 
inventory actions, discord chat relay, and all features.

Getting Started

Setup and Download

System Requirements

1. Linux, Windows, or Mac computer. I recommend using a VPS (droplet) from DigitalOcean:
   • $200 Free DigitalOcean Credits.
   • Guide and automatic setup script.
2. Java 21+ (Not required for linux release channel on supported CPU)
   • The ZenithProxy launcher will install Java 21 automatically if not already installed

Launcher

1. Download the launcher zip for your system
   • For other systems, download the Python version (Universal). Requires Python 3.10+
2. Unzip the file.
3. Double click or run the launcher executable in a terminal:
   • Windows: .\launch.exe
   • Linux/Mac: ./launch
   • (Terminal Only) Python Universal: ./launch.sh (Linux/Mac) or .\launch.bat (Windows)

How do I download a file from a Linux terminal?

• Use wget in the terminal
• Example: wget https://github.com/rfresh2/ZenithProxy/releases/download/launcher-v3/ZenithProxy-launcher-linux-amd64.zip

Recommended unzip tools

• Windows: 7zip
• Linux: unzip
• Mac: The Unarchiver

Recommended Terminals

• Windows: Windows Terminal
• Mac: iterm2

Run

• The launcher will ask for all configuration on first launch
  • Or run the launcher with the --setup flag. e.g. .\launch.exe --setup
• Use the connect command to link an MC account and log in once ZenithProxy is launched
• Command Prefixes:
  • Discord: . (e.g. .help)
  • In-game: / OR ! -> (e.g. /help)
  • Terminal: N/A -> (e.g. help)
• Full Commands Documentation

Running on Linux Servers

See the Linux Guide

I highly recommend using a terminal multiplexer - a program that manages terminal sessions.

If you do not use one, ZenithProxy will be killed after you exit your SSH session.

• (Recommended) tmux
• screen
• pm2

Configuration

Release Channels

• (Default) java - Supports all operating systems
• (Recommended) linux - Linux native x86_64 executable. ~50% reduced memory usage and instant startup

DNS Setup

• To use a domain name you need the following DNS records:
  • an A record to the public IP address of your server Example
  • an SRV record for _minecraft._tcp with the port and the A record as its target. Example

Discord Bot Setup

• Create a discord bot here: discord.com/developers
• Enable Message Content Intent under the "Bot" tab. Example
• Invite the discord bot to a server.
• Create a role for users to manage the proxy, a channel to manage the proxy in, and a channel for the chat relay. The bot's role must have permissions to send and receive messages in both channels
• Configure in ZenithProxy using the discord command. Or run the launcher with the --setup flag.

Running Multiple Instances

Create a new folder for each instance with its own copy of the launcher files. Example

Instances must be independently run and configured. i.e. separate terminal sessions, discord bots, ports, config files, etc.

See the Linux Guide for help copying files, creating folders, etc.

2b2t Limits

2b2t limits accounts without priority queue based on:

1. Accounts currently connected per IP address
2. In-game session time, excluding time in queue.

Current limits are documented in a discord channel
