Install Node.js (version 14 or higher recommended) 2. Run `npm install` to install dependencies 3. Edit the `credentials.json` file with your Minecraft account details 4. Start the bot using: - Windows: Run `start.bat` - Linux/Mac: Run `chmod +x start.sh` and then `./start.sh` ## Configuration Edit the config object in `afk-bot.js` to change: - Server details - Chat messages - Reconnect timing - Other bot settings ## Features - Minimal resource usage - Automatic reconnection - Simple chat responses - Multiple account support This optimized AFK bot uses several techniques to minimize CPU and RAM usage: 1. Disabled physics engine 2. Minimal view distance 3. Disabled chunk loading where possible 4. Reduced event handling 5. Memory-optimized Node.js flags 6. Explicit garbage collection hints 7. Paused entity tracking 8. Limited plugin loading To use it, just update the credentials.json file with your Minecraft accounts and run the start script.
