The PLAY function returns the number of remaining notes in the background music queue.
Syntax
- numericExpression& = PLAY (numericExpression&)
Parameters
- notesLeft& is the number of notes left to play in the background music queue.
- numericExpression& can be any numeric expression. This is ignored.
Description
- This function may be used to detect, if the background music queue is still playing.
- When there is nothing left to play, then this function returns zero.
Availability
none
v3.1.0
yes
yes
yes
- In QB64, this function always returned zero.
- Unlike QuickBASIC, in QB64-PE this function does not return the number of notes left, but the number of audio samples.
- In QB64-PE v3.8.0 if numericExpression& is a number other than zero, then the function will return the amount of time (seconds) left to play.
Examples
PLAY "mb l4cf.l8el4fag.l8fl4gl8agl4f.l8fl4a>cl2dl4dl4c.<l8al4afg.l8fl4gl8agl4f.l8dl4dcl2f>l4dc.<l8al4afg.l8fl4g>dc.<l8al4a>cl2dl4dc.<l8al4afg.l8fl4gl8agl4f.l8dl4dcl1f" PRINT "Playing tune..." DO playLeft& = PLAY(0) LOCATE , 1: PRINT "Left to play ="; playLeft&; " "; LOOP WHILE playLeft& PRINT: PRINT "And we are done!" END |
