Position changes on the scale of the layer
Hi Awesome Peoples;
I am animating a graph which has a bar(rectangle) and point(circle) which is on the upper edge of the bar. The bar is scaling from 0 to 100 in the y-direction. I tried an expression in the position of the point but it does not follow the bar to its total length.
For a basic idea of my layer and position
x=thisComp.height;
sy=thisComp.layer("bar").transform.scale[1];
m=x-sy;
[transform.position[0],m]; -

If your circle layer has it’s anchor point centered you could try this expression on it’s position property:
L = thisComp.layer("bar");
r = L.sourceRectAtTime(time,false)
L.toWorld([r.width/2,r.top]);

Thank you so much!!! that really helps man…I am new to scripting and especially new to “toWorld” expression. Made a few tweaks on my side to work as I needed. Final expression is bellow
L = thisComp.layer("bar");
r = L.sourceRectAtTime(time,false);
s=L.toWorld([r.width/2,r.top]);
[value[0],s[1]];
