Aligning a Lower third to a specific position in the based on the with of a box
Hi everyone,
I’m creating a L3 Mogrt. there are text boxes that react to the width of the text.
My question is: These text boxes are center aligned, and therefore I’m not able to anchor there x position with my expression knowledge.
Is there a way for the Null to calculate what the largest box is, and have the left edge of that largest box fix itself to an assigned x – Pos without loosing the center alignment of other boxes?
Here are some examples of that I need it to do and my timeline.
Many thanks,
Emma

Try this for the null’s position (set leftEdge to your desired x value):
leftEdge = 35;
L1 = thisComp.layer("Shape Layer 1");
x1 = L1.toComp([L1.sourceRectAtTime(time,false).left,0])[0];
L2 = thisComp.layer("Shape Layer 2");
x2 = L2.toComp([L2.sourceRectAtTime(time,false).left,0])[0];
L3 = thisComp.layer("Shape Layer 3");
x3 = L3.toComp([L3.sourceRectAtTime(time,false).left,0])[0];
xMin = Math.min(x1,x2,x3);
delta = leftEdge - xMin;
value + [delta,0] -
Hi Dan,
This has magically worked, thank you so much this is amazing 🌟
