Playing sound when changing sound volume bar?

[Saa]

Hi! I'm trying to make it so, when you change the sound volume in the preferences menu, a sound plays (so you can immediately hear how your new volume will sound). I know there's a "test" button, but I don't want it; I want the sound to play on its own without the user needing to do anything. I've tried this code:

Code: Select all

if config.has_sound:

	label _("Sound Volume")

	hbox:
		bar value Preference("sound volume") changed renpy.sound.play('bgm/click.wav')

But for some reason, it just makes sound play every single time I click something interactive (which could be desirable, if it didn't also play as soon as the game opens). How do I make it work?

Maybe you should only play the sound when the bar is "hovered", then stop it when "unhovered", as "changed" also give the change value as an argument:

The problem might be due to the fact that ren'py predict the screens effects and content even before they are shown (for speed reason I think), but that mean that it might compute "renpy.sound.play('bgm/click.wav')" as soon as you can open the screen, and not when you interact with the bar. If you want the sound to play for the whole screen, you could use the "on "show"" key-word to start it and "on "hide"" to stop it:

Hope that could help
