|
|
|
@input Play: Plays the sound, or if paused, resumes the playback.
|
|
The exact behaviour depends on the Retrigger option (see below).
|
|
@input Pause: Pauses the playing sound. If no sound is playing,
|
|
nothing happens.
|
|
@input Stop: Stops the playing sound. If the playback is paused,
|
|
this will reset the playback position to the start of the sound.
|
|
@input Update Volume: Updates the volume of the current playback.
|
|
@input Volume: Volume of the playback. Typically ranges from 0 to 1.
|
|
|
|
@output Out: activated once when Play is activated.
|
|
@output Running: activated while the playback is active.
|
|
@output Done: activated when the playback has finished or was
|
|
stopped manually.
|
|
|
|
@option Sound/Sound Name: specify a sound by a resource or a string name
|
|
@option Sound: The sound that will be played.
|
|
@option Stream: Stream the sound from disk.
|
|
@option Loop: Whether to loop the playback.
|
|
@option Retrigger: If true, the playback position will be reset to
|
|
the beginning on each activation of Play. If false, the playback
|
|
will continue at the current position.
|
|
@option Sample Rate: Manually override the sample rate of the sound
|
|
(this controls the pitch and the playback speed).
