I followed the YouTube video.
It worked great for a horizontal slider, but I can't get it to work vertically.
It is supposed to stay within the sliderSide (which is set at 50% opacity)
It keeps going beyond the slider and not staying within the size of the slider.
There is a slider on either side. This slider is sliderSide and moveSide.
Note, ignore the controller under the slider, that will go as soon as I get this slider working.
