Table of contents

Installation

Install using yarn

Install the package with yarn

yarn add mineflayer-dashboard

Install using npm

Install the package with npm

npm install --save mineflayer-dashboard

Initialization

Then load up the plugin using mineflayer. You can pass options argument:

  • chatPattern - a pattern that is tested against a message to determine if it's chat message or a system message. It's better to add this option as mineflayer's chat pattern will match messages like [SkinsRestorer] Your skin has been changed.. Also custom patterns are much faster than mineflayer's default one.
bot.loadPlugin(require('mineflayer-dashboard')({
  chatPattern: /^» \w+? » /
}))
// or
bot.loadPlugin(require('mineflayer-dashboard'))

Layout

+--------------------+-----------+
|                    |           |
|                    |           |
|     MODE WINDOW    |    LOG    |
|                    |           |
|                    |           |
+----+---------------+-----------+
|MODE| TEXT INPUT                |
+----+---------------------------+
  • TEXT INPUT - Here you insert your text / commands
  • MODE - Mode indicator, tells you current mode
  • LOG - Here you can print out some stuff
  • MODE WINDOW - Here you can print out mode related stuff

Logging

Logging in log window is accessible by using bot.dashboard.log function.

NOTE: Please do not use console.log as it may create some unwanted artifacts. If any other dependency is using console.log you may try to overwrite this function by

bot.once('inject_allowed', () => {
  global.console.log = bot.dashboard.log
  global.console.error = bot.dashboard.log
})

Error logging

All error logging is passed to the dashboard log window. That means all of the error handlers created before plugin load are no longer listened. This was a crucial step to maintain the layout of the app.

Modes

Included modes

Dashboard comes with 2 modes:

  • CHAT - Default mode. In CHAT mode you can see all of the chat messages sent to the player.
  • REPL - In REPL mode you can run javascript code to control over your bot.

Defining custom modes

We expose Mode class in the bot.dashboard.

The first parameter is mode name. It'll be used to create :<name> command to switch to this mode

Second one is options:

  • fg - foreground color for mode indicator
  • bg - background color for mode indicator
  • interpreter - It defines what is happening when you hit enter in the text input. Bound to mode instance
  • completer - This function should return String[] or Promise<String[]> with the completions to current string. Bound to mode instance
    • A single completion needs to be the remainder of the completed string. For example, when I want to complete nickname wvffle and I hit <tab> with cursor posiotioned in position wv| then I need to return [ 'ffle' ]
  • bypassDefaultCompletion - bypass default completion system, don't cache matches.

Example whisper mode

When in this mode, we can send messages to different players. To change the reciever simply add :to <user> at the end of the message

let lastUser = null
const whisper = new bot.dashboard.Mode('whisper', {
  bg: 'blue',
  interpreter (string) {
    let words = string.split(' ')

    // Check if we change receiver
    if (/ :to \w{3,16}$/.test(string)) {
      lastUser = words[words.length - 1]
      words = words.slice(0, -2)
    }
    
    // Log an error if there is no receiver
    if (lastUser === null) {
      return bot.dashboard.log("No receiver set, please add ' :to <user>' at the end of the message")
    }   

    // Send message
    const message = words.join(' ')
    bot.chat(`/msg ${lastUser} ${message}`)
    this.println(`to ${lastUser}: ${message}`)
  },
  async completer (string) {
    // We're using already well defined minecraft completer
    return bot.dashboard._minecraftCompleter(string)
  }
})

bot.dashboard.addMode(whisper)

bot.on('whisper', (username, message) => {
  // Log a notification if not in whisper mode
  if (bot.dashboard.mode !== whisper) {
    return bot.dashboard.log(`You have a new message from ${username}`)
  } 

  // Display messages in the mode
  whisper.println(`${username}: ${message}`)
})

Commands

Running commands

Simply type :<command> arg1 arg2...

:say wvffle "I like waffles"

NOTE: In this case :say is a custom command
NOTE: In this case "I like waffles" is a string passed as arg2

Available commands

We provide some basic commands for the dashboard.

  • :help - Display available commands
  • :exit - Kill the bot / exit the application
  • :clear - Clear mode window
  • :<mode> - Change to <mode> mode
    • :chat - Change to CHAT mode
    • :repl - Change to REPL mode

Custom commands

You can add custom commands by simply doing

bot.dashboard.commands['say'] = (user, ...words) => {
  const sentence = words.join(' ')
  bot.chat(`/forcesay ${user} ${sentence}`)
}
