How would I do this

I’m working with the ease expression and I’m trying to find out how(if possible at all) to map position to rotation. I successfully achieved mapping it one way. Adding the ease expression to position and controlling rotation but I want to use the inverse and add the ease to rotation. I’m missing the ball I”m sure; I noticed that when you pickWhip in this situation AE creates temp parameters… I think that’s the problem but I don’t know how to translate that into the ease… here is the expression i tried to add to rotation:ease(transform.position,[value[0],value[1]],[value[0],value[1]],0,360)
I get an error saying that there isn’t a class called zero….
Not sure what that meansease(transform.position,[value[0],value[1]],[value[0],value[1]],0,360) -

The output of ease() can be an array (like position) but the input can’t — it needs to be one-dimensional. Depending on what you’re doing, you might be able to use the position to calculate a one-dimensional distance from some point (maybe the first position point) and use ease() to translate that to rotation. Hard to be more specific without more details…

I succeeded in applying the ease to position then I added an ease(just for kicks) to rotation so that as ease expression ran the object moves and rotates.
The goal was to invert this animation and have the expression swapped 🙂 I failed though
