const mf = require('mineflayer')
const pv = require('prismarine-viewer')

const bot = mf.createBot({
    username: 'Bot',
    password: 'pass',
    host: '185.35.19.210',
    port: 25565,
})

bot.once('spawn', () => {
    pv(bot, { port: 3000 })

    bot.chat('/log password')

    const path = [bot.entity.position.clone()]
    bot.on('move', () => {
        if (path[path.length - 1].distanceTo(bot.entity.position) > 1) {
            path.push(bot.entity.position.clone())
            bot.viewer.drawLine('path', path)
        }
    })
})

I tried to connect the plugin https://github.com/G07cha/MineflayerAutoAuth but I couldn’t, because of incomprehensible mistakes for me. The usual prismarine-auth won’t work for me because I don’t have a license. I will be waiting for your comments.
