360º incremental layer rotation with pauses
I have spent days researching this:
I have a circle with 40 numbers (years 1984 through 2024) equally distributed around its perimeter.
I can keyframe this circle of numbers to:
Rotate -9 degrees for 12 keyframes;
Stop and hold rotation for 24 keyframes;
Then repeat from last rotation value to continue 360º of the 40 numbers.
I am using a null as the control layer but cannot cobble together an expression to achieve this using valueAt Time etc.
Thank you for any tips or articles you can share.

This is just a rough stab at it, without actually seeing what you’re doing, but I think it’s going to look something like this:
r = thisComp.layer("r_control").transform.rotation;
val = 0;
if (time >= r.key(2).time){
n = Math.floor((time - r.key(2).time)/(r.key(4).time - r.key(2).time));
t = (time - r.key(2).time)%(r.key(4).time - r.key(2).time);
val = r.key(4).value*n + r.valueAtTime(t + r.key(2).time);
}

Dan, Thank you for the concept. I will study it, learn from it, try it. I read your post on time control in your blog which was also most educational, particularly in reference to the easing aspects of the range.

It worked perfectly.

Thank you for this solve, Dan!
