Control slider with variation
Hi everyone,
I have a shape layer with 20 shapes, all with a Stroke and a Trim Paths.
The 20 separate shapes’ Trim Paths are linked to a Slider Control which animates from 0 to 100.
In order to add some variation in the time it takes for the Trim Paths to animate on, I am trying to add an expression to the individual shapes that takes into account the Slider Control animation, but then adds a random time offset.
Ideally, the random time offset would not let the animation of the Trim Paths start before my first keyframe on the Slider Control.
Can you help?
Thanks – Jack

Something like this maybe:
maxOffset = .2;
s = effect("Slider Control")("Slider");
if (s.numKeys > 1){
seedRandom(index,true);
offset = random(-maxOffset,maxOffset);
t1 = s.key(1).time;
t2 = s.key(2).time;
t = linear(time,t1,t2+offset,t1,t2);
s.valueAtTime(t);
}else
value

Thanks for getting back to me, Dan.
The script you suggested is throwing up a few errors (namely that the use of ‘else’ at the end is illegal!).
I’m attaching a screengrab of the composition which I hope will shed light on the issue.
Thanks again,
Jack

It looks like you didn’t quite get the second and third lines copied correctly. The second line is missing a semi-colon at the end, the third is missing an opening curly bracket at the end.

Thanks, Dan!
User error, as always.
Thanks for your time on this.

Hi Dan,
I have a shape layer with one stroke inside and I would like to animate the shape property using a slider control.
When time = 0, k1 = k2, but when time in 1s. (exemple), k2 = k1 + slider controle value.
Do you know how to do it?
Thks,
edo

Dan, don’t need it.
You have already answered it before in another place. I found it on Adobe Groups. The girl even mentioned you as a brilliant (what you really are).
Thks
