Mineflayer Mouse

First-class battle-tested simple API for emulating real Minecraft mouse control in Mineflayer. You should use it for digging (mining) or placing blocks and entity attacking or using and using items!

Note: This module will be deprecated once the functionality is merged into the main mineflayer library with 1:1 implementation.

Installation

pnpm add mineflayer-mouse

Features

Predict block placement (optimistic update, needed for correct physics on high ping)
Block breaking server cancellation
Accurate entity raycasting (targeting)
Debug logging

Philosophy

Note: this library is used in minecraft web client project. Try mineflayer viewer lib: mcraft-fun-mineflayer to see it in action!

The world interaction system in Minecraft is complex and not easy to replicate. We have two hands and different holding item/blocks logic along with different entities and activatable items and blocks in the world. For example:

Would what happen if you right click on a crafting table with a torch in left hand and potion in right hand? But if you are shift clicking it? But if you are loooking at entity? Should the item be used or entity interaction happen?

Using hardcoded methods like bot.attack will make your bot act not natural and more likely would result in ban.

Usage

import { createMouse } from 'mineflayer-mouse';
import { createBot } from 'mineflayer';

const bot = createBot({
  host: 'localhost',
  port: 25565,
});

bot.loadPlugin(createMouse());

// based on returned entity or block you can determine what action would happen (you cant enfoce specific action since thats not how game works)
const { entity, cursorBlock, cursorBlockDiggable } = bot.mouse.getCursorState();

// attack entity
bot.leftClick();
// start digging block
bot.leftClickStart()
// stop digging block
bot.leftClickEnd()

// place block
bot.rightClick()

// start placing block
bot.rightClickStart()

// ...

Roadmap

Tests
Block placement prediction
Raycast, item/block activatable, block prediction overrides
Better item activation
Arm animation & use item on block place check world env
Validate packets on item activation on entity
