Hey,
It must be something I am overlooking, but I can’t for the life of me get the isPlaying('slotname') method of PlayCanvas’ SoundComponent to work. See documentation
I have an entity with a SoundComponent with a slot named ‘Slot1’ and the following code snippet:
this.entity.sound.play('Slot1'); //Works fine
this.entity.sound.isPlaying('Slot1'); //For some reason throws error
Anyone see why this doesn’t work?
Hi @Astra,
I see you commented that you are receiving an error. Could you elaborate on what error you’re receiving?
This returns true or false. So I don’t think it’s useable like this.
ah, ok. my bad. the way I’m actually using it is like this:
if(!this.entity.sound.isPlaying('Slot1')){
this.entity.sound.play('Slot1');
}
just thought it be easier to explain with the other example 
and the error I’m getting is:
“this.entity.sound.isPlaying is not a function”
(however, this.entity.sound.play is clearly a function since that alone works just fine)
It’s a quite new function and I think you use it correct now. I didn’t use it myself yet, so not sure what could be the problem.
Maybe you can try to use the old method?
if (!this.entity.sound.slot('Slot1').isPlaying) {
this.entity.sound.play('Slot1');
}
hm… weird now I’m getting “this.entity.sound.slot is not a function”…
I’m guessing it might be something weird with our project setup?
I’ll try with a fresh project
Looks like the function was added for 1.62 engine release (not out yet) and isn’t in 1.61.
I’m not sure why the docs have been released for 1.62 
Will have to fix that when I get a chance
For now, use the method explained here: Prevent a sound from starting repeatedly · Issue #4885 · playcanvas/engine · GitHub
I double checked in the new blank project and the “this.entity.sound.slot(‘Slot1’).isPlaying” call worked there, so I guess there was something with our larger project that was interfering or something.
