I think Dan summed up the issue, expressions cant read the value of the expressed layer… in programming I would just have a global var to hold the value between cycles… Thats easy… Wish AE had some kind of global var storage. I know people have talked of storing in sliders but when i tried that I still got the same issue when it was trying to add to the current value.

I gave up anyway and hand animated it as I had to get the work done. Not perfect but it did the job of a concept design.

Yeah seems simple… but ” thisComp.layer(“Speed Dial”).rotation ” is referencing the layer this expression sits on. And for some reason refuses to see the actual value… Thats my problem

Another way to ask the question…

In expressions how do I do value=value+10 ?

An equation that takes the current expressed value and adds ontop of it?

Ahh thanks that was a typo when i posted… but sadly doesnt work

To really simplify the explanation… nullobject 1 is having its rotation value keyframed. I want to have nullobject 2 chase the values.

But im discovering that AE expressions cant see the value of the property the expression is running on.

Im having this same issue with another expression where im trying to find the current value thats being calculated for it. And add ontop of that current value.

Basically in the expression i posted here speed is getting NULL ie, not any value.
