Constantly keep following a player

[Sunderw3k]

Basically im trying to constantly follow a player and update thier position. My code looks something like this:

const mineflayer = require("mineflayer");
const pathfinder = require('mineflayer-pathfinder').pathfinder;
const Movements = require('mineflayer-pathfinder').Movements;
const { GoalNear } = require('mineflayer-pathfinder').goals

if (process.argv.length != 5) {
    throw new Error("Usage: node main.js <username> <address> <port>")
}

const options = {
    username: process.argv[2],
    host: process.argv[3],
    port: parseInt(process.argv[4])
};

const bot = mineflayer.createBot(options);
let following = false;

bot.loadPlugin(pathfinder)
bindEvents(bot);

function bindEvents(bot){
    
    bot.once("login", () => {
        console.log(`${process.argv[2]} joined the server!`);
    });

    bot.on("chat", async (author, message) => {
        if (author == bot.username) { return };

        if (message.startsWith("follow")) {
            following = true
            while (following) {
                goToPlayer(bot, message.split(" ")[1])
                await sleep(500)
            }
        }
        if (message == "stop") {
            following = false
        }
    });

    bot.once("end", (reason) => {
        console.log(`${process.argv[2]} ended! End reason: ${reason.reason}`);          
    });
}

const sleep = ms => new Promise(r => setTimeout(r, ms));

getCoords = (bot, name) => {
    const player = bot.players[name] ? bot.players[name].entity : null;
    if (player) {
        return player.position;
    } else {
        return null;
    }
};

goToPlayer = (bot, name) => {
    coords = getCoords(bot, name)

    if (coords) {
        const mcData = require('minecraft-data')(bot.version);
        const defaultMove = new Movements(bot, mcData);

        bot.pathfinder.setMovements(defaultMove);
        bot.pathfinder.setGoal(new GoalNear(coords.x, coords.y, coords.z, 1));
    }
}

It's updating the position every 500ms but trying to move to it makes the bot stop any actions - like sprinting, mining a block. I would like to follow the player but not stop anything. Im probably going to need to rewrite my logic but I can handle it.

Oh so i realised I can just use GoalFollow instead of GoalNear. Let me know if thats correct?

[amoraschi]

Yes, it is correct

One question. I am using

const followPlayer = (bot, playername) => {
    const player = bot.players[playername] ? bot.players[playername].entity : null;

    if (!player) {
        return false;
    }

    const mcData = require('minecraft-data')(bot.version);
    const defaultMove = new Movements(bot, mcData);

    bot.pathfinder.setMovements(defaultMove);
    bot.pathfinder.setGoal(new GoalFollow(player, 1), true);
    return true;
}

and want to follow the player after he dies. Right now the bot keeps standing in the death spot.
