What is this?

This is a plugin for Mineflayer a high level Node.js API for creating Minecraft Bots. Mineflayer-panorama allows you to make pretty panorama images off the world the bot is in.

Getting Started

This plugin is built using Node and can be installed using:

git clone https://github.com/IceTank/mineflayer-panorama.git
cd mineflayer-panorama
npm install

Example

For use as a plugin to make Panorama Images:

const panorama = require('./index')
const mineflayer = require('mineflayer')
const fs = require('fs')
const bot = mineflayer.createBot({
  host: 'localhost'
})

bot.on('spawn', async () => {
  console.info('Bot spawned')
  bot.loadPlugin(panorama.image)
  bot.on('camera_ready', async () => {
    await bot.waitForChunksToLoad()
    console.info('Ready to use')
    let imageStream = await bot.panoramaImage.takePanoramaPictures()
    let image = fs.createWriteStream('panorama1.jpeg')
    imageStream.pipe(image)
    image.on('finish', () => {
      console.info('Wrote panorama image panorama1.jpeg')
    })
  })
})

This plugin also includes a webserver that can be used to view the generated images. The webserver opens a website on a given port and serves the current panorama view of the bot and a Panorama viewer. For an example see: example/browserCubeMap/index.js. Note: three.module.js has to be provided in public/js. If npm install did not download it, it has to be added manually.

Running on Windows

The rendering is done by node-canvas-webgl which is tricky to install on Windows. I recommend using a unix based operating system or Docker to run this plugin.

Documentation

async bot.panoramaImage.takePanoramaPictures(camPos)

Takes a panorama Image and resolves with a jpeg stream of that image on success.

  • camPos - a null, number or Vec3 like object
    • null - takes the panorama image from the bot current position
    • number - takes the panorama image with a high offset at the bots current location
    • Vec3 like - takes the panorama image at a given location. Note: the bot can only render chunks that are loaded. Taking images outside of the current render distance may result in a blank image off the current sky color.

async bot.panoramaImage.takePicture(lookAt, name)

Takes a picture of the current world at the bots current position looking at the point lookAt

  • lookAt - a Vec3 like object of the point the bot should look at
  • name - the name the jpeg image will be saved as

WebServer(bot, PORT)

A class providing a express app to host the panorama viewer on. When the page is opened the web server automatically calls bot.panoramaImage.takePanoramaImage to take an up to date panorama image to display in the panorama viewer.

  • bot - the mineflayer bot instance
  • PORT - the port the express app should listen on

WebServer.READY - boolean if the express app is ready

Events

"ready"

Emitted when the express app is ready and running

Docker

Example Dockerfiles are provided in the examples. To build an example Dockerfile use this command:

docker build . -f .\example\<the example>\Dockerfile -t <image name>

For running the container read the README.md files in the example folders.

TODO

  • Add panorama Video streaming/saving
  • Add entitys to the panorama view
