scaling an object at a special position
hello,
i wanted to build a kind of animated timeline, the function a bit like
the alarm setting on the iphone (scrolling up and down the numbers).
i uploaded an picture where it is better explained.
there i try to animate a timeline of years verticaly. the year
wich will be exactly in the center of my grafic should be scaled.
when it leaves its position it should be scaled down again.
i wanted to try this with an expression, and found some expressions
about scaling an object at a special time. but i dont get it changed to
“scale at a special postiion”.
i am not very good in this expressions, maybe someone knows an solution?
thanks a lot, greetz!

This should scale the layer to 125% as it approaches the center of the comp:
yPos = thisComp.height/2;
maxScale = 125;
range = 50;d = Math.abs(transform.position[1] - yPos);
ease(d,0,range,[maxScale,maxScale],value)
Play around with the first three parameters to set: the y position where maximum scale occurs; the maximum scale value; and the distance at which the scaling starts.

It occurred to me that your numbers may be parented to some other layer. If so, try changing this line:
d = Math.abs(transform.position[1] – yPos);
to this:
d = Math.abs(toComp(anchorPoint)[1] – yPos);
