Type Alias BpxSoundSequence

BpxSoundSequence: {
    intro?: BpxSoundSequenceEntry[];
    loop?: BpxSoundSequenceEntry[];
}

A definition of a sequence of sounds to be played. A typical use case would be to define a music which consist of an intro phase, then loops indefinitely. Another use case is to recreate the music composed in PICO-8 – it usually is built from many short samples, tied together. Moreover, the BpxSoundSequence allows to crop the sample, which might be useful for a PICO-8 music composed of samples shorter than default 32 bits, but exported as 33-bits long.

Example

 const halfDuration = (fullSoundDurationMs: number) => fullSoundDurationMs * 16 / 32;
 $x.startPlaybackSequence({
   intro: [
     [{ url: "intro1Melody.flac", durationMs: halfDuration }],
     [{ url: "intro2Melody.flac", durationMs: halfDuration }, { url: "intro2Bass.flac" }],
   ],
   loop: [
     ["loop1Melody.flac", "loop1Bass.flac"],
     ["loop2Melody.flac", "loop2Bass.flac"],
     ["loop3Melody.flac", "loop3Bass.flac"],
   ],
 });
