Detailed description of a problem

when using example farmer.js I got an error: Error: Event blockUpdate:(10651, 64, 99656) did not fire within timeout of 5000ms

What did you try yet?

Did you try any example? Any error from those? YES, the exact error I'm facing

Your current code

const mineflayer = require('mineflayer')
const prismarineViewer = require('prismarine-viewer')
const { mineflayer: mineflayerViewer } = require('prismarine-viewer');
const items = require('./items.json')
const { Vec3 } = require('vec3')


const bot = mineflayer.createBot({
  host: '6b6t.org',
  username: 'bot',
  password: 'password',
  version: '1.12.2'
})

bot.once('spawn', () => {
  mineflayerViewer(bot, { port: 3007, firstPerson: true }) // port is the minecraft server port, if first person is false, you get a bird's-eye view
})

bot.on('spawn', (cm) => {
  setTimeout(() => { 
    console.log('Task is running')
    bot.chat('/login password')
    bot.setControlState('forward', true)
  }, 2000);
  setTimeout(() => {
    bot.setControlState('forward', false);

  }, 6200)
  setTimeout(() => {
    // loop();
  }, 20000);
})

// To fish we have to give bot the seeds
// /give farmer wheat_seeds 64

function blockToSow () {
  return bot.findBlock({
    point: bot.entity.position,
    matching: 60,
    maxDistance: 250,
    useExtraInfo: (block) => {
      const blockAbove = bot.blockAt(block.position.offset(0, 1, 0))
      return !blockAbove || blockAbove.type === 0
    }
  })
}

function blockToHarvest () {
  return bot.findBlock({
    point: bot.entity.position,
    maxDistance: 260,
    matching: (block) => {
      return block && block.type === 296 && block.metadata === 7
    }
  })
}

async function loop () {
  try {
    while (1) {
      const toHarvest = blockToHarvest()
      if (toHarvest) {
        await bot.dig(toHarvest)
      } else {
        break
      }
    }
    while (1) {
      const toSow = blockToSow()
      if (toSow) {
        await bot.equip(295, 'hand')
        await bot.placeBlock(toSow, new Vec3(0, 1, 0))
      } else {
        break
      }
    }
  } catch (e) {
    console.log(e)
  }

  // No block to harvest or sow. Postpone next loop a bit
  setTimeout(loop, 1400)
}


bot.once('login', loop)

Expected behavior

It should farm

Additional context

Add any other context about the problem here.

[rubencosta13]

and like 99% of the examples result in bugs, you should specify the tested version for mineflayer

[extremeheat]

open for PR

[rubencosta13]

Any updates?

[Lyh0yh]

hi bro
I have the same problem as you.
Have you solved the problem？

[rubencosta13]

Not really.....

[maximmasiutin]

Also confirm in 4.5.1

[iiCodeRedemption]

Still a thing in the latest version (4.20.0).

[RogiersJ03]

For now I just catch the error and ignore it.

for (const coord of blocksToFarm) {
        await new Promise( (resolve, reject) => {
            bot.pathfinder.setGoal(new GoalNear(coord.x, coord.y, coord.z, 1));

            bot.once('goal_reached', async () => {
                const block = bot.blockAt(coord, false);
                const seedItem = bot.inventory.items().find(item => item.name === "wheat_seeds");

                if (seedItem === undefined) {
                    bot.chat(`/tell ${username} I need seeds.`);

                    reject('NoSeeds');
                }

                try {
                    await bot.dig(block, true);
                    await bot.equip(seedItem, 'hand');

                    const position = bot.blockAt(new Vec3(coord.x, coord.y-1, coord.z));
                    await bot.placeBlock(position, new Vec3(0, 1, 0));

                    resolve();
                } catch (err) {
                    if (err.message.includes('Event') && err.message.includes('did not fire within timeout')) {
                        console.log('Timeout error occured.');
                        resolve();
                      } else {
                        console.log(err);

                        reject();
                      }
                }
            });
        });
    }

• I have the same problem in version 4.8.1

[boly38]

• I'm trying to placeBlock (usign mineflyer in 4.23.0 and minecraft aternos server version1.20.3) & I encounter this issue too
• I equip one block in bot hand (ex. await bot.equip(bot.registry.itemsByName.crafting_table.id, 'hand')
• and I add some log in my findClearPosition (cf gist) method used before placeBlock :

console.log(`==>> check position : ${targetPos} | block under is ${blockBelow?.name || 'null'}, at target bock is ${blockAtTarget?.name || 'null'}`);

This make me understand that depend on the block below, then the issue is reproduced:

• crafting table + chest + blue_bed + ... (probably more.)(&avoid bot position ;))

To fix that it would be great to tell here (or remind or document) the good way to find clear position to place a block :) (as it's a common need) 👍

• the provided gist link has been updated with botUtil___FIXED.js file as (quite enough) fixed sample, and maybe may help to improve doc/lib/both.

(+reproduced same issue when bot is trying to place item at player position // possible fix in findClearPosition using round() => && targetPos.round() !== botPos.round())
