[Reverse timeline animation on scroll direction]

Thank you! 

 

I'll use one of the helper functions

[Reverse timeline animation on scroll direction]

Hello!

 

I'm trying to replicate the animation on this website : https://www.simplex.ca/en (Section "Our advices")

 

The animation seems to work well when you scroll "up" since it only adds speed to the current animation. But when you scroll down, it does start to reverse but it doesn't keep its direction. 

 

I tried to change the "x" but it didn't seem to change anything

 

Do you know how to fix this?

Thank you!
