make sure the slider is marked as a variable in the widget editor, switch back to the event graph pull out the widget component reference for the slider, then type get value
Unless you have a specific reason to use that version of the slider, i’d just use a regular slider instead of audio slider base
You should be able to copy the visual settings of the audio slider onto the regular slider
as far as calculating db goes, there’s probably a way to do that, but most ppl would probably prefer that it was just a % type thing out of 100 as that’s how there used to their OS audio settings/sliders
Setting the regular type slider to be vertical is fairly easy, and from there you just copy the visual settings i think called something like “Thumb down” “Hovered” etc, i’ll find a picture of them here in a bit
Edit:
So, copying it straight up might not be as easy as i made it sound, you’ll have to find what the Img being used there is called in the engine files… or probably just make your own in Photoshop or paint or whatever
