A Stepmania sextet lighting library for NodeJS

This was developed for another project so it only currently fills the needs of that right now.

Stepmania Sextet stream is a finnicky thing to set up on windows. You can use https://github.com/stepmania/stepmania/blob/master/src/arch/Lights/LightsDriver_SextetStream.md for more indepth setup. Stepmania on windows is a stream client and sends data to the server.

The steps are this:

• Configure stepmania to stream data.
  • In the Preferences.ini set LightsDriver=SextetStreamToFile and set the SextetStreamOutputFilename=.\StepMania-Lights-Output
• Create symlink because stepmania does not properly handle named pipes.
  • In powershell New-Item \\.\pipe\StepmaniaLightsOutput -ItemType SymbolicLink -Value [path to stepmania folder]\StepMania-Lights-Output this symlinks the named pipe path to a file path that stepmania can use.
• Start your code that uses this library
• Start stepmania

Unfortunately the way stepmania also works hinders being able to restart the server while stepmania is running as well.

The library is event driven so that you can get only the data you want. Normally stepmania resends the complete set of lights as a message any time any light updates. Each event name represents 1 byte as an int val that changed in the stream.

The event names are: "marquee", "p1Buttons", "p1Cabinet", "p1Pad", "p1Extended1", "p1Extended2", "p1Extended3", "p2Buttons", "p2Cabinet", "p2Pad", "p2Extended1", "p2Extended2", "p2Extended3"

import { autoConnect } from 'stepmania-lights'

const PIPE_NAME = "StepMania-Lights-SextetStream"

const PIPE_PATH = "\\\\.\\pipe\\" + PIPE_NAME

const stepmania = autoConnect("WIN32PIPE:" + PIPE_PATH)

stepmania.on("marquee", (val) => {
  const topLeft = val & 1
  const topRight = val >> 1 & 1
  const bottomLeft = val >> 2 & 1
  const bottomRight = val >> 3 & 1
  ...
})

import { autoConnect } from 'stepmania-lights'

const PIPE_NAME = "StepMania-Lights-SextetStream"

const PIPE_PATH = "/usr/local/games/stepmania/Data/" + PIPE_NAME

const stepmania = autoConnect("FIFO:" + PIPE_PATH)
