Thanks Dan,

I think I understand how this is working, using time to create the loop. Pretty basic stuff, but seems quite useful.

I appreciate the help,

Okay, I found a solution to my problem, again thanks to a post from Dan Ebberts.

Actually, I spoke too soon, that expression works, until I add the loop to it. Then it seems to override the time remapping expression and just loops the default duration of the keys as though the preceding code didn’t exist.
Back to the drawing board.

I found a way to resolve this using another post that Dan Ebberts answered. Though I’m not sure if there is an easier way to do it.
This is the post that I got it from:

This is my final expression and it seems to do the trick quite nicely:

holdTime = effect(“line_passage”)(“Slider”);
k1 = 1; // 1st hold keyframe
k2 = 2; // 2nd hold keyframe
p = effect(“Beam”)(“Time”);
t1 = p.key(k1).time;
t2 = t1 + holdTime;
if (time < t1)
t = time
else if (time < t2)
t = linear(time,t1,t2,t1,p.key(k2).time)
else
t = p.key(k2).time + (time – t2);
valueAtTime(t)

loopOutDuration(type = “cycle”, duration = 0)

Yes. Worked like a charm. Thanks Dan, this is not the first time you’ve saved my hide!

Hi Dan,

That is actually exactly what I was asking for, but I’m now realizing that it is not right for what I’m doing. I tried to figure out how to change the expression to match my needs but I’m running up against a wall.

Basically I’m creating a slider that consists of a row of small whites cubes. As I increase my slider control the cubes individually wobble, and turn orange. The decay of the wobble is perfect, but I’m now realizing that as long as the slider value is up the cubes need to stay full orange, once the slider falls below their number, they need to fade back out to white.

So I think the expression needs to tell the opacity to change to 100% once the sliderVal >= triggerVal, and remain at that value until the sliderVal falls below the trigger val, at which point the opacity should begin to fade to zero.

I hope this is enough information. And again, thank you so much for your expertise — your website is the reason I am brave enough to even try using expressions.

Thanks Dan, that was exactly what I was looking for. I really appreciate the help.
