string of objects to follow a psuedo Bezier
Hi all,
I am having a touch of a hard time figuring out Dan’s awesome tutorial:
https://www.motionscript.com/expressions-lab-ae65/bezier.html
I am trying to pull this off only the test scenes of the solids are not following nulls as I imagined. Has anyone did this before where they might want to share their AE scene for me dissect?
What I did was made a solid and under the position, I pasted the expressions Dan shared.
Nothing happened as mentioned in the tutorial and no immediate gratification was established once I pasted the expression as instructed.Thanks for any who help out.

What do you need help with?

After adding the slider expression control to Null 1 the modification the script should read:
N1 = thisComp.layer(“Null 1”);
N2 = thisComp.layer(“Null 2”);
N3 = thisComp.layer(“Null 3”);
N4 = thisComp.layer(“Null 4”);p0 = N1.position;
p1 = N2.toWorld(N2.anchorPoint);
p2 = N3.toWorld(N3.anchorPoint);
p3 = N4.position;c = 3*(p1 – p0);
b = 3*(p2 – p1) – c;
a = p3 – p0 – c – b;t0 = index/(thisComp.numLayers – 3);
s = N1.effect(“Slider Control”).param(“Slider”);
if(s < 0){
s += 1;
t = t0*s;
}else{
t = s + t0 – s*t0;
}((a*t +b )*t + c)*t + p0
