Sliders with motion paths going backwards
Hello! Newbie here.
I was hoping this wonderful community could give me some advice. I want a slider to dictate the movement of an object, but each tick on the slider representing a different position along a path. I also want to be able to move the slider backwards and the object move backwards along a slider.
I've tried a few tutorials, such as the one here (with using a slider instead of buttons):
But when you move the slider backwards, the object moves out of the frame.
I attached a picture that hopefully describes what I'm trying to accomplish. Thank you in advance for you help!
