The PLAY function returns the number of remaining notes in the background music queue.


Syntax

notesLeft& = PLAY (ignored%)


Parameters

  • notesLeft& is the number of notes left to play in the background music queue.
    In QB64-PE
    this is the number of audio samples left to play in the background music queue.
  • ignored% can be any numeric expression. This is ignored.


Description

  • Use this to detect if the background music queue is still playing.
  • Unlike QuickBASIC, this does not return the number of notes left but the number of audio samples.
  • When there is nothing left to play, this returns zero.


Availability

  • QB64-PE v3.1 and up (QB64 Phoenix Edition)


Examples

PLAY "mb l4cf.l8el4fag.l8fl4gl8agl4f.l8fl4a>cl2dl4dl4c.<l8al4afg.l8fl4gl8agl4f.l8dl4dcl2f>l4dc.<l8al4afg.l8fl4g>dc.<l8al4a>cl2dl4dc.<l8al4afg.l8fl4gl8agl4f.l8dl4dcl1f"
