Hello, I use the well-known expression of Dan Ebbert to control the scrolling of a layer in a composition. This expression is:

spd = thisComp.layer("SPEED CONTROL").effect("Layer speed control")("Slider");
n = spd.numKeys;
if (n > 0 && spd.key(1).time < time){
accum = spd.key(1).value*(spd.key(1).time - inPoint);
for (i = 2; i <= n; i++){
if…

Thank you, it work 🙂

Here the code for information :

curseur = (thisComp.layer("TraceArc").effect("C2")("Curseur"))/100;
decalage = thisComp.layer("TraceArc").content("Ellipse 1").content("Réduire les tracés 1").offset;
angle = 2 * Math.PI * curseur - (Math.PI / 2) + degreesToRadians(decalage);
cosangle = Math.cos(angle);
sinangle = M…

Hello everyone,

I’m currently working on an After Effects project and encountering a challenge with an expression. I would greatly appreciate your expertise in helping me identify and resolve the issue.

Objective:I am trying to control the position of a point on a circle using an expression. The circle is part of a layer named “TraceArc,” and I’m a…
