Position reaction expression

Take a look at this video. The red line moves right as the time scale moves left (from 1945 to 1964). I'm wondering what expression I could give the time scale so that it moves automatically to the left when I move the red line to the right.

<grumble> I really wish AE had a feature like 3DS Max's Reaction controller </grumble>.

Thank you.

Correct answer Dan Ebberts

I did. See attached.


Ah, with dimensions separated I guess it would be like this:

p = thisComp.layer("Red Line").transform.position;

linear(p[0],352,1538,2114,-658);

Basically all I'm looking to do is

When object Red Line x = 352

object Base x should = 2114

When object Red Line x = 1538

object Base x should = -658

Thanks.

I haven't tested it, but something like this should work:

p = thisComp.layer("Red Line").transform.position;

x = linear(p[0],352,1538,2114,-658);

[x,value[1]]

Thanks, Dan. I'm getting an error saying "Property or method named '1' is missing or does not exist. It may have been renamed, moved deleted, or mistyped."
