This is a simple Minecraft bot built using Mineflayer that connects to a Minecraft server, handles registration and login, and simulates human behavior.

• Automatic registration and login on the server
• Human-like behavior simulation (looking around, jumping, swinging arm, sneaking, moving)
• Error handling and reconnection logic
• Ignores known chat parsing errors for version 1.21

• Node.js (version 22 or higher)
• A Minecraft server (e.g., Aternos server as configured)

1. Clone or download this repository.
2. Install dependencies:

   npm install
   

For security, sensitive information like the bot password is stored as environment variables.

• BOT_PASSWORD: The password for the bot's account on the Minecraft server.

If deploying on your host with Environment Variables:

• Variable Name: BOT_HOST (required, set as Secret)
• Variable Name: BOT_PORT (required, set as Secret)
• Variable Name: BOT_USERNAME (optional, default: 'PixelForgeStudio')
• Variable Name: BOT_AUTH (optional, default: 'offline')
• Variable Name: BOT_PASSWORD (required, set as Secret)
  • Value: Your actual bot password

For local development, create a .env file in the project root:

BOT_PASSWORD=YourActualPasswordHere

And install dotenv package:

npm install dotenv

Then, add at the top of bot.js:

require('dotenv').config()

Run the bot:

node bot.js

The bot will connect to the configured server and start simulating human behavior.

• mineflayer: For creating and controlling the Minecraft bot
• minecraft-data: Minecraft data for Mineflayer
• prismarine-chat: For chat handling

• The bot is configured for Minecraft version 1.20.4.
• It reconnects automatically if disconnected, with a 30-second delay.
• Ensure the server allows offline authentication if using auth: 'offline'.
