Vertical Movement

Hey guys,

I've been trying to figure out how I can make an object loop up and down in a certain area. I tried to use the path tool but having issues getting it to be a straight line, and when I do there's a bit of a weird effect to it.

Any tips or tutorial links I can follow?

 

Have u used transform logic ?

 

Thanks, I watched this tutorial and figured it out.

Appreciate it!
