I want to create a slider which should look like this After Effects animation I did: https://dominikdelgado.com/wp-content/uploads/2020/09/IntegralMap-Slider-Animation.mp4
The website seen in the animation already exists besides the silder: https://integralmap.one
The part I don’t know is: How can I build a silder (like visualized in the animation) where one can use the mouse to push the circle-indicator up and down and where the indicator snaps into 12 different positions (according to the 12 different layers of the 3D model) while triggering the right id’s?
I hope my question was clear and someone can help me out with that. It would be greatly appreciated!
