Vertical slider

Having a brain fart on how to set up a vertical slider control for scrolling y over two layers, where slider.y max=windowheight, or layer 1 height, and scrolly max= layoutheight, or layer 0 height.

Im trying set scrolly to lerp(0,layoutheight,... and the rest escapes me atm.

Any thoughts?

A = difference between slider starting y and ending y

B = slider initial position

C = slider maximum value you want

lerp(0, layoutheight, ((slider.y - B) / A) * C)

I think this is it

EDIT: actually, I think you don't even need the lerp() there

Thanks, I think I figured it out.
