This function gets the buffer playback length of the specified sound. Works only with streams.
Składnia
float getSoundBufferLength ( element theSound )
Składnia OOP Pomocy, nie rozumiem!
- Metoda: sound:getBufferLength(...)
- Wartość: .bufferLength
Wymagane argumenty
- sound: element dźwięku, którego długość chcesz pozyskać.
Zwraca
- Wartość zmiennoprzecinkową, która zawiera długość dźwięku w sekundach.
- fałsz jeżeli dźwięk nie jest strumieniem.
- nil jeżeli dźwięk jest nieprawidłowy.
Przykłady
Ten przykład rysuje prosty odtwarzacz, który pokazuje długość pobranej części utworu.
