PLAY (function)

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.
• ignored% can be any numeric expression. This is ignored.

QuickBASIC/QB64 differences

• In QB64-PE notesLeft& is the number of audio samples left to play in the queue instead of the notes left.

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)
