Detailed description of a problem

bot wont connect to the server properly
it just printed "bot create success **(see my code)" in the console
the server has this log: UUID of player BotAccT is b33b9df3-a39b-31f9-8fe2-f10c1f01c4fb

What did you try yet?

i even hadnt got an error about it in my console while running the programs/examples.the bot just woudnt connect.

Your current code

const mineflayerViewer = require('prismarine-viewer').mineflayer
const mineflayer = require('mineflayer');
const readline = require('readline');
// 创建机器人
const bot = mineflayer.createBot({
  host: 'p**********n', // Minecraft 服务器地址
  port: 1***6,        // Minecraft 服务器端口
  version: '1.21.4',
  username: 'BotAccT',     // 机器人的用户名
  auth: 'offline',
  hideErrors: 'false'
});
console.log('bot create success');
// 设置控制台输入
const rl = readline.createInterface({
  input: process.stdin,
  output: process.stdout
});

// 监听控制台输入
rl.on('line', (input) => {
  const command = input.trim().toLowerCase();

  switch (command) {
    case 'w':
      bot.setControlState('forward', true);
      break;
    case 's':
      bot.setControlState('back', true);
      break;
    case 'a':
      bot.setControlState('left', true);
      break;
    case 'd':
      bot.setControlState('right', true);
      break;
    case 'stop':
      bot.clearControlStates();
      break;
    case 'j':
      bot.setControlState('jump', true);
      setTimeout(() => bot.setControlState('jump', false), 500);
      break;
    default:
      if (command.startsWith('/')) {
        // 如果是指令（以 / 开头）
        bot.chat(command); // 发送指令
      } else if (command) {
        // 如果是普通聊天消息
        bot.chat(command); // 发送聊天消息
      } else {
        console.log('未知命令');
      }
  }
});

// 机器人连接成功时触发
bot.once('spawn', () => {
  console.log('机器人已连接，可以通过以下命令控制：');
  console.log('w: 前进');
  console.log('s: 后退');
  console.log('a: 左移');
  console.log('d: 右移');
  console.log('jump: 跳跃');
  console.log('stop: 停止移动');
  console.log('/<command>: 执行指令（例如 /help）');
  console.log('<message>: 发送聊天消息');
  mineflayerViewer(bot, { port: 3007, firstPerson: false })
});

// 机器人断开连接时触发
bot.on('end', () => {
  console.log('机器人已断开连接');
  rl.close();
});

// 机器人错误处理
bot.on('error', (err) => {
  console.error('机器人发生错误:', err);
});

Expected behavior

the bot could connect to the server properly, using version 1.21.4.

Additional context

please.....anyone who could help?

bot create success
机器人已连接，可以通过以下命令控制：
w: 前进
s: 后退
a: 左移
d: 右移
jump: 跳跃
stop: 停止移动
/: 执行指令（例如 /help）
: 发送聊天消息
Prismarine viewer web server running on *:3007

connected fine to my paper 1.21.4 server so its likely your server causing issues

ive been using mineflayer on 1.21.x servers for a bit now

See if you can reproduce on a different server. Otherwise, it could be a server specific problem that can't be fixed without you debugging it

I don't know what server this person is playing on, but given their server host says p**********n, and the comments are in Chinese, it appears the server IP may be play.***.cn. Given that Hypixel China shut down a few years ago, I'm fairly certain the server @Thomasnbawa is attempting to connect to is not Hypixel.

All that to say, there's at least 2 independent servers that exhibit this same behavior. This one, and Hypixel.

play.wynncraft.com has a same problem with 1.20.5+.

What is "same problem" ? This issue has 0 information yet, so how can you identify it's the same problem?

Please follow the debug info in the readme to provide info so it's possible to debug.

If you want to make sure that non vanilla server get better support in general then contribute to #1200

Sorry, I forgot to comment here, but this is likely a duplicate of #3623.

[rom1504]

#3623 also has no information so yes it's a duplicate in the sense "cannot reproduce or fix"

[rom1504]

Ah you did put the debug info there I see

[PseudoResonance]

#3623 also has no information so yes it's a duplicate in the sense "cannot reproduce or fix"

Hardly... It has a full repo for minimal reproduction, debug logs, analysis of the cause and a likely error...

[rom1504]

Yeah so definitely not a duplicate

[PseudoResonance]

Yeah so definitely not a duplicate

Well, my issue was documented a whole lot better than this one, but I'm pretty sure the root cause at least is the same. Although, I guess we will never know if @Thomasnbawa never provides anything... Oh well.
