I am trying to use blockfinder to find a chest and have the bot stand on it but it gives me this error:

Refactor blockfinder
Refactor this module to make re-use of the logic between findBlock and findBlockSync. See this issue on helperbot.
setGoal doesn't work on goal_reached?
I think it's just an error that I made, or setGoal really doesn't work on the goal_reached event.
Here's my code:
const { pathfinder, goals, Movements } = require('mineflayer-pathfinder');
const blockfinder = require('mineflayer-blockfinder')(mineflayer);
const bot = mineflayer.createBot({ host: 'xxx', port: 'xxx', username: 'woodfetcher' });
bot.loadPlugin(pathfinder);
bot.loadPlugin(blockfinder);
let player;
bot.once('spawn', () => {
const mcData = require('minecraft-data')(bot.version);
const defaultMovements = new Movements(bot, mcData);
bot.on('chat', (username, message) => {
player = bot.players[username].entity;
if (message === 'fetch wood') {
bot.findBlock({
point: bot.entity.position,
matching: 17,
maxDistance: 256,
count: 1
}, (err, blocks) => {
if (err) return console.error(err);
if (blocks.length >= 1) {
bot.chat('Fetching wood!');
const pos = blocks[0].position;
bot.pathfinder.setMovements(defaultMovements);
bot.pathfinder.setGoal(new goals.GoalBlock(pos.x, pos.y, pos.z));
}
});
}
});
bot.on('goal_reached', () => {
bot.chat('Got wood!');
if (player) {
bot.pathfinder.setMovements(defaultMovements);
bot.pathfinder.setGoal(new goals.GoalFollow(player, 2));
}
});
});
RangeError: Maximum call stack size exceeded
I don't know what changed but I'm getting this running https://github.com/Darthfett/mineflayer-blockfinder/blob/master/examples/diamondFinder.js now (with the last commit from mineflayer)
(I noticed this because I'm using this plugin in https://github.com/rom1504/rbot)
Assertion Error
Using the following code:
case '!findportal':
try {
bot.findBlock({
point: bot.entity.postition,
matching: 181,
maxDistance: 256,
count: 1,
}, function(err, blocks) {
if (err) {
return console.log(err)
}
if (blocks.length) {
pos = blocks[0].position
bot.chat("I found a portal at " + pos + ". Going there now...")
bot.navigate.to(pos)
return;
} else {
bot.chat("Portal not found.")
return;
}
});
} catch(err) {
console.log(err)
}
break
Gives me:

What am I doing wrong?
Cannot override bot.findBlock
Greetings,
I just installed this plugin and after debugging my project I noticed that its implementation is always ignored in favor of the one in mineflayer.
Here's some code snippets:
My project's code:
var bot = mineflayer.createBot({
...
});
// Install the plugin - method override is done here
blockFinderPlugin(bot);
// Sample usage
bot.once('spawn', function() {
bot.findBlock(...) // the original findBlock is called instead of the plugin`s
});
The injection function blockFinderPlugin is successfully called and the override code also succeeds:
function findBlockSync(options) {
...
}
function findBlock(options, callback) {
...
}
bot.findBlock = findBlock;
bot.findBlockSync = findBlockSync;
Yet the original function is always called instead. I don't know if the issue belongs here or at themain repo, so apologies if this isn't meant for here.
Cheers
Finding a chest, opening it.
Minecraft version 1.16.1
Hello, I found this example of chest opening and withdrawing items. https://github.com/PrismarineJS/mineflayer/blob/1abfe102766175b27fa39cb6cf587da6fc9a2d9a/examples/chest.js
But I couldn't find a chest.
So I found this plugin and tried the usage example.
I lowered the maxDistance, otherwise, it crashes. I placed a diamond ore next to the player, and it didn't find a single block.
It just returns an empty array
If there's no way to fix this. Is there a way to open a chest at given coords? (constructing a Block)
Count Option is Broken
Many blocks found when the count > 1 are duplicates, although not all of them.
Does this mean that the search algorithm is iterating over some blocks multiple times?
Uncaught TypeError: undefined is not a function
Woops, wrong repository. Ignore me, I'm stupid.
"I couldn't find any Diamond Ore blocks within 256."
There is clearly diamond ore like 60 blocks underground.
It doesn't work.
I'm using the example
point: bot.entity.position,
matching: 56,
maxDistance: 256,
count: 1,
trying to get more block then the possibile in the chunk will cause the bot crash
bot.findBlock({
point: bot.entity.position,
matching: [54, 57],
maxDistance: 256,
count: 7,
}
if the block are more the bug will be not caused but if there are not much block then the count the bot will crash without error
Node Package Not Up To Date
If I specify mineflayer-blockfinder 0.0.5 in my package.json and run npm install, the saved files are not the latest version. (MAX_CPU_SPIN = 100, not 10)
I have to manually link this repository's latest commit to get the correct version.

matching array should be an array of block types
instead of an array of item/block enums.
I can's find log block :(
My script can't find any wood block with ID 17 or 4 ... Can you help me ?
New blockfinder algorithm too slow
The new blockfinder algorithm now takes 4 minutes to check 64 blocks in all directions from the player (This is 128^3 blocks).
The new algorithm actually checks all these blocks, unlike the old algorithm, which only worked sometimes.
Block cant be found
I think its the same issue as #19
I've set the ID to bedrock (7)... but for some reason it seems like it can never find anything. No bedrock, no grassblocks, nothing.
What was the fix @moom0o that eventually helped you out? Or anyone else knows what is going on?
const mineflayer = require('mineflayer')
var blockFinderPlugin = require('mineflayer-blockfinder')(mineflayer);
const fs = require('fs')
function createBot () {
const bot = mineflayer.createBot({
host: '192.168.137.1',
port: 25565,
username: 'MAIL',
password: 'PASSWORD',
auth: 'microsoft'
})
bot.loadPlugin(blockFinderPlugin);
//
// blockFinderPlugin(bot);
bot.on('spawn', function() {
console.log("[BOT] - Spawned")
bot.findBlock({
point: bot.entity.position,
matching: 7, //90 = portal, 49 = obsidian, 1 = stone, 7 = bedrock
maxDistance: 16,
count: 1,
}, function(err, blocks) {
console.log("[BOT] - findBLocks function started")
if (err) {
bot.chat('Error trying to find Bedrock: ' + err);
setTimeout(kill, 5100)
}
console.log(blocks)
if (blocks.length) {
return bot.chat('I found a Bedrock block at ' + blocks[0].position + '.');
} else {
bot.chat("I couldn't find any Bedrock within 256.");
setTimeout(kill, 5100)
}
});
});
bot.on('error', (err) => {
console.log(err)
process.exit(1)
})
// setInterval(kill, 5100)
function kill () {
bot.chat("/kill")
}
}
createBot()
as you can see above, the console.log(blocks) gives an empty console
