Playing and Stopping Sounds

Sounds are created then played or stopped in routines.
See the reference guide for details.

For most portability, use mp3 files for your sounds. These should play on all major platforms.

The name of your sound file must be inside double quotations marks.

The example below will play the sound, then stop it after 3 seconds.

Playing Sound

create sound from "dial-tone.mp3" as sndSample where repeat=1 volume=.5 fadein=500 fadeout=500 end create sprite as temp having alt=(sub create wait where delay=3000 completion=Stop end) end create routine as Start play sound sndSample launch temp end create routine as Stop stop sound sndSample where fadeout=1000 // overrides default end

Muting and Pausing Sounds

When a sound is playing you can pause the sound or mute it. Of course you can also unpause and unmute. Muting and pausing support fading as appropriate.

create sprite as s end // a container for the timers create sound from "dial-tone.mp3" as sndSample where volume=.5 fadein=500 fadeout=500 end create routine as Start play sound sndSample launch s insert into s where alt=(sub create wait where delay=1000 completion=Pause end) insert into s where alt=(sub create wait where delay=2000 completion=Unpause end) insert into s where alt=(sub create wait where delay=3000 completion=Mute end) insert into s where alt=(sub create wait where delay=4000 completion=Unmute end) end create routine as Pause pause sound sndSample where fadeout=500 end create routine as Unpause unpause sound sndSample where fadein=500 end create routine as Mute mute sound sndSample where fadeout=500 end create routine as Unmute unmute sound sndSample where fadein=500 end

Cloning Sounds

When you create a sound and play it, playing it again will cancel the instance that is already playing. This doesn't sound good.

To play multiple copies of the same sound at the same time, use cloning.
You clone a sound, update any values for the new clone instance, and it immediately plays.
You can still mute or pause the clone if you assigned it a name.

create sprite as s end // a container for the timers create sound from "shame.mp3" as sndSample where volume=0.5 end create routine as Start play sound sndSample launch s insert into s where alt=(sub create wait where delay=1000 completion=DoneWait end) end create routine as DoneWait clone from sndSample as SoundClone update sound _clone where volume=1 insert into s where alt=(sub create wait where delay=2000 completion=StopClone end) end create routine as StopClone stop sound SoundClone where fadeout=1000 end
