void Caveats & Gotchas
- • If Sound is null, Play() does nothing — always assign Sound before calling Play.
- • Restarting a looping sound via Play() causes a brief audio discontinuity. Use FadeOut followed by FadeIn for smooth transitions.
- • StartTime seeking is not supported by all codecs. ADPCM does not support seek; use PCM or BinkAudio if you need reliable StartTime offsets.
Examples
Simple play from beginning C++
MyAudioComp->Play(); Seek into the middle of a clip C++
// Start 5 seconds into the sound
MyAudioComp->Play(5.0f);Tags
