"""Compare the music manager with the vanilla 26.3 client.
|
|
|
|
The oracle runs the real `MusicManager` over the real `SoundEngine` (OpenAL
|
|
Soft "No Output" device, see VanillaSoundRig). The situation
|
|
(`getSituationalMusic`, `getMusicVolume`), the loading screen, pauses, the
|
|
end of a track, `stopPlaying`, `setMinutesBetweenSongs`, the music category
|
|
volume and `showNowPlayingToastIfNeeded` are script inputs; every step prints
|
|
the current track, `nextSongDelay`, `currentGain`, `toastShown`, the toast
|
|
calls, the MUSIC category gain and the music channel's AL source. Horizon's
|
|
`MusicManager` and `SoundEngine` replay the scripts. Tracks use events whose
|
|
variants share one volume, since `forMusic` resolves with an unseeded random.
