Video Tutorial

For a video tutorial explaining the usage of mineflayer-pathfinder, you can watch the following Youtube videos:

Example

const mineflayer = require('mineflayer')
const pathfinder = require('mineflayer-pathfinder').pathfinder
const Movements = require('mineflayer-pathfinder').Movements
const { GoalNear } = require('mineflayer-pathfinder').goals
const bot = mineflayer.createBot({ username: 'Player' })

bot.loadPlugin(pathfinder)

bot.once('spawn', () => {

  const mcData = require('minecraft-data')(bot.version)

  const defaultMove = new Movements(bot, mcData)
  
  bot.on('chat', function(username, message) {
  
    if (username === bot.username) return

    const target = bot.players[username] ? bot.players[username].entity : null
    if (message === 'come') {
      if (!target) {
        bot.chat('I don\'t see you !')
        return
      }
      const p = target.position

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

Features

• Optimized and modernized A* pathfinding
• Complexe goals can be specified (inspired by baritone goals )
• Customizable movements generator
• Each movement can have a different cost
• Can break/place blocks as part of its deplacement
• Automatically update path when environment change
• Long distance paths
• Can swim

API

Considering there are a lot of deep changes that are being worked on, it could take some time before it's done

Also, for now, there is only the pathfinder module, movements and goals still need to be done

Functions:

bot.pathfinder.bestHarvestTool(block)

Returns the best harvest tool in the inventory for the specified block

• Returns - ?
• block - Block instance

bot.pathfinder.getPathTo(movements, goal, done, timeout)

• Returns - The path
• movements - Movements instance
• goal - Goal instance
• timeout - number (optional, default bot.pathfinder.thinkTimeout)

bot.pathfinder.setGoal(Goal, dynamic)

• goal - Goal instance
• dynamic - boolean (optional, default false)

bot.pathfinder.setMovements(movements)

Assigns the movements config

• movements - Movements instance

bot.pathfinder.isMoving()

A function that checks if the bot is currently moving.

Properties:

bot.pathfinder.thinkTimeout

Think Timeout in milliseconds

• Default - 5000

Events:

goal_reached

Called when the goal has been reached. Is not called for dynamic goals.

path_update

Called whenever the path is recalculated. Status may be:

• success a path has been found
• partial a partial path has been found, computations will continue next tick
• timeout timed out
• noPath no path was found

goal_updated

Called whenever a new goal is assigned to the pathfinder.

Goals:

GoalBlock(x, y, z)

One specific block that the player should stand inside at foot level

• x - Integer
• y - Integer
• z - Integer

GoalNear(x, y, z, range)

A block position that the player should get within a certain radius of

• x - Integer
• y - Integer
• z - Integer
• range - Integer

GoalXZ(x, z)

Useful for long-range goals that don't have a specific Y level

• x - Integer
• z - Integer

GoalY(y)

Get to y level

• z - Integer

GoalGetToBlock(x, y, z)

Don't get into the block, but get directly adjacent to it. Useful for chests.

• x - Integer
• y - Integer
• z - Integer

GoalCompositeAny(Array?)

A composite of many goals, any one of which satisfies the composite. For example, a GoalCompositeAny of block goals for every oak log in loaded chunks would result in it pathing to the easiest oak log to get to

• Array - Array of goals

GoalCompositeAll(Array?)

A composite of many goals, all of them needs to be satisfied.
