Detailed description of a problem

A clear and concise description of what the problem is, with as much context as possible. Weird error that doesn't allow me to create a bot. That's all I know. What are you building? A pathfinding bot that follows me when I say "follow me" What problem are you trying to solve?

What did you try yet?

Did you try any method from the API? I don't know how to. Did you try any example? Yes Any error from those? No

Your current code

// Here I tell node.js mineflayer and a few other plugins are required to load
const { versions } = require('minecraft-data')
const MinecraftData = require('minecraft-data')
const mineflayer = require('mineflayer')
const { pathfinder, Movements, goals } = require('mineflayer-pathfinder')
const GoalFollow = goals.GoalFollow
const pvp = require('mineflayer-pvp').plugin

// Here, we set up the server connection (in this case, my skin plugin server)
const bot = mineflayer.createBot({
    host: 'SonicJavaBots.aternos.me',
    port: '37867',
    username: "SonicandTailsCDb",
    version: '1.18.2'
})

// And now, we work on the AI here!
// Here's all of the functions:
// One note tho: All functions are placeholders.
function onPhysicsTick () {}

function onSpawn () {
    bot.chat("Hey! I'm working properly :D")
    bot.chat("/skin set SonicandTailsCDb robot1_stevetest")
}

function onSpawnMessage () {
    bot.on('chat', (daname, msgg)=>{
        const player = bot.players[daname]
        if (msgg == "follow me") {
            bot.chat("Okay " + daname)
        }
        if (!player || !player.entity){
            bot.chat("I can't see you, " + daname) 
            return
        }
        const data = require('minecraft-data')(bot.version)
        const movements = new Movements(bot, data)
        bot.pathfinder.setMovements(movements)

        const goal = new GoalFollow(player.entity, 2)
        bot.pathfinder.setGoal(goal, true)
    })
}

// I need to set physicsTick because I want the AI to target me.
bot.on('physicsTick', onPhysicsTick)

// Next, I'm gonna set spawn actions.
bot.once('spawn', onSpawn)
bot.on('spawn', onSpawnMessage)

Expected behavior

A clear and concise description of what you expected to happen. I expected the bot to join and follow me when I say "follow me"

Additional context

Add any other context about the problem here. NO. Thanks :)

You didn't load the pathfinder plugin. Add the code below under mineflayer.createBot():

bot.loadPlugin(pathfinder)

[ghost]

btw, you should just move bot.on('chat') inside onSpawn and remove bot.on('spawn', onSpawnMessage) and onSpawnMessage

[SonicandTailsCD]

btw, you should just move bot.on('chat') inside onSpawn and remove bot.on('spawn', onSpawnMessage) and onSpawnMessage

The thing is that a server plugin sends the spawn message to the client when its skin is loaded. That causes the bot to loop sending a command.

You didn't load the pathfinder plugin.

I'm gonna try to load the server now with the correction...

[SonicandTailsCD]

Also, wanna join the server? We try to fix it in real time? It isn't an issue if you don't agree.

[SonicandTailsCD]

LOL it said "I can't see you, SkinsRestorer". How do I fix this?

yeah sure

[SonicandTailsCD]

Alright. You know the IP and port?

[ghost]

yup

I'm ready! :D
