link scale to certain degrees
Hi!
I have a really easy issue with linking scale to rotation, but I’m trying with no success, this is what I’m trying:
1.I have a vertical line(shape layer) with its anchor point at the bottom of the shape.
2. I’d like to animate the y scale (via expressions), so when I rotate the line to: 0,90,180..etc the scale is 100% and if the rotation angle is 45,135,225, etc.. the scale is 50
3.(if going ahead with the rotations it keeps the pattern, that would be great)I’ve been trying some messy expressions, but I always miss something and it’s not working at all 🙁
many thanks!!

Like so:
rot = Math.abs(transform.rotation);
y_scale = 50+50*Math.abs(rot % 90 -45)/45;
[transform.scale[0], y_scale] -
works like a charm! thanks!!!
