const bot = mineflayer.createBot(
    options
);

bot.once('login', async () => {
    console.log("Logined: " + bot.username);
});

bot.on('message', async json => {
    const text = json.toString();
    console.log(`[${bot.username}] ${text}`);
});

bot.once('spawn', async () => {
    await new Promise(r => setTimeout(r, 2000));
    bot.chat(`/an21`);
    console.log(`${bot.username} joining to server...`);

bot.on('error', err => {
    console.log(err.message);
