MusicStream

[konsumer]

I wrote a simple demo in raylib, in C, that loads a mod music file, and I am trying to create the same thing in node:

const r = require('raylib')

r.InitWindow(320, 240, 'music demo')
r.SetTargetFPS(60)

const music = r.LoadMusicStream('assets/the_golden_ages.mod')
r.PlayMusicStream(music)

while (!r.WindowShouldClose()) {
  r.UpdateMusicStream(music)

  r.BeginDrawing()
  r.ClearBackground(r.BLACK)
  r.DrawText('HELLO!', 10, 10, 20, r.LIGHTGRAY)
  r.EndDrawing()
}

r.UnloadMusicStream(music)
r.CloseWindow()

It appears like it's working, and prints "Hello!" on screen, but I don't hear any sound.

It outputs this:

In C I needed this:

#define SUPPORT_FILEFORMAT_MOD

How do I add this to node-raylib?

Ah, silly me, I forgot I needed InitAudioDevice() in C, too. I added it and it works great:

const r = require('raylib')

r.InitWindow(320, 240, 'music demo')
r.SetTargetFPS(60)
r.InitAudioDevice()

const music = r.LoadMusicStream('assets/the_golden_ages.mod')
r.PlayMusicStream(music)

while (!r.WindowShouldClose()) {
  r.UpdateMusicStream(music)

  r.BeginDrawing()
  r.ClearBackground(r.BLACK)
  r.DrawText('HELLO!', 10, 10, 20, r.LIGHTGRAY)
  r.EndDrawing()
}

r.UnloadMusicStream(music)
r.CloseWindow()

Sorry for the queue-noise.

We could add a check in the constructor to ensure it's initialized.

Nah, not necessary at all. I like that it works the same, personally, just an error on my part.

Sidenote: I love what you did with this. It works really well, and mirrors the C interface really closely (so far) so it's fairly easy to figure out how to make stuff work.
