Fading Music

I haven't found a thread much about this but, is there a clean way so that i can make music fadeout as I leave the layout? :3

I have not heard of any way of going about doing this so your best bet is to create a variable that increases over a few ticks and set your gain to the negative of that variable and when it is greater than 20, move to the layout

Or without a variable, and using dt for a smoother effect : events

Yes, this is quite simple. Whenever you would trigger to go to the next layout, delay it a bit. Have a variable as something like "fadeoutmusic" and then set it to 1 when you would end the layout. This is also a good time to fade in an all-black tiled background over top of the layout to have it fade to black, but that's for another day.

-If fadeoutmusic = 1, set audio volume to Audio.Volume("yourmusictag")-200*dt

-Compare 2 variables

------if Audio.Volume("yourmusictag") < or = 0, Go to layout, trigger once

I'm having a bit of confusion when I try

set audio volume to Audio.Volume("yourmusictag")-200*dt

It says it's looking for a string not a number?
