miitopia discord bot

This discord bot will add random snippets of the miitopia sound track to images and videos sent to it.

Usage

Attach an image to your message in discord and mention @miitopia.

You can add a url to a short MP3 (myinstants.com for example) or a spotify URI to the message to make miitopia use that instead.

Setup

1. Install rust and cargo.

2. Clone this repo. git clone git@github.com:SeeSharpeDen/miitopia.git and cd to miitopia

3. obtain the miitopia sound track and make sure it's the correct format. See soundtrack

4. Optional. add spotify api client env vars.

   go to https://developer.spotify.com/dashboard/applications and create a new application.

   • Set the SPOTIFY_ID env var for spotify client id.
   • Set the SPOTIFY_SECRET env var for spotify client secret.

5. Set the env vars and run cargo run.

   • The DISCORD_TOKEN env var is required. It stores your discord bot token.
   • The RUST_LOG env var sets the logging. Read here for more details.

   Example: RUST_LOG=warn,miitopia=debug DISCORD_TOKEN="[ Token Goes Here ]" cargo run

Soundtrack

The miitopia soundtrack you've downloaded very likely isn't in the format miitopia is expecting.

The audio files must be an ogg file with the .ogg extension. They also need a single track (no album art) with the vorbis or opus codec.

Example:

$ ffprobe -hide_banner miitopia_001-A-Lively-Inn.flac.ogg
Input #0, ogg, from 'miitopia_001-A-Lively-Inn.flac.ogg':
  Duration: 00:01:54.95, start: 0.000000, bitrate: 100 kb/s
  Stream #0:0: Audio: vorbis, 32728 Hz, stereo, fltp, 112 kb/s
    Metadata:
      encoder         : Lavc58.134.100 libvorbis
      ALBUM           : Miitopia Original Soundtrack
      ARTIST          : Toshiyuki Sudo, Shinji Ushiroda, Yumi Takahashi, Megumi Inoue
      COMPOSER        : Toshiyuki Sudo, Shinji Ushiroda, Yumi Takahashi, Megumi Inoue
      DATE            : 2021

      title           : A Lively Inn
      track           : 1

The audio files need to be stored in the resources/music directory.

Example:

resources/
└── music
    ├── miitopia_001-A-Lively-Inn.flac.ogg
    ├── miitopia_002-Mmmmm.flac.ogg
    :   ...
    └── miitopia_336-Nintendo-3DS-Home-Menu-Banner.flac.ogg

Converting

You can convert your existing miitopia/music library to this format with ffmpeg.

The example bash script below converts files ending with .flac in the ~/Music/miitopia/ directory to an .ogg file with no video (-vn), with the audio codec of libvorbis (-acodec libvorbis).

#!/bin/bash
for file in ~/Music/miitopia/*.flac
do
    ffmpeg -i $file -vn -acodec libvorbis resources/music/$(basename $file).ogg
done

This script can be condensed to a single line like below.

for file in ~/Music/miitopia/*.flac; do ffmpeg -i $file -vn -acodec libvorbis $(basename $file).ogg; done
