Follow the x position of the layer above.
Hey there people,
I am trying to animate a list where I have animated the X position of the top layer and want all the other layer to follow the position of the layer above it. I am using this expression
x=thisComp.layer(index-1).transform.position[0].valueAtTime(time);
[x,value[1]]but it’s not working. I am getting this error thisComp.layer(index-1).transform.position[0].valueAtTime(time) is not a function.
x=thisComp.layer(index-1).transform.position[0].valueAtTime(time);
[x,value[1]] -

You should put the [0] at the end of the first statement.
Long story:
As soon as it encountered the [0], the expression did an implicit look up of the value() of transform.position, which returned a 2 or 3 dimensional array, of which it yielded the first [0]thd element.
Consequently it interpreted the rest of the statement as if you were asking .valueAtTime() of a number, which is not a function, I guess. ☺so to recap:
x=thisComp.layer(index-1).transform.position.valueAtTime(time)[0];
[x,value[1]]
