Really helpful to rocket my un= derstanding of scripting.=C2=A0

Henry,

Here's something really basic I just= whipped up that simply moves layers away from a null.=C2=A0 It just pushes= objects=C2=A0away from where the null is when they're closer than the = "Distance Threshold" control.=C2=A0 You can increase the amount t= hat they move with "Move Away Multiplier."

Just paste the position expression from one of the solids to your own la= yers and it should work or at least be a starting point to tinker further.= =C2=A0 Expression pasted below as well:

Here's= a quick screencapture showing what it does:


Not fancy but= maybe helpful?
=C2=A0- Nathan

p =3D transform.position;
nullPos =3D thisComp.layer(&qu= ot;Parent And Controls").transform.position;
distanceThreshold =3D = thisComp.layer("Parent And Controls").effect("Distance Thres= hold")("Slider");
moveAwayMult =3D thisComp.layer("P= arent And Controls").effect("Move Away Muliplier")("Sli= der");

distance =3D length(p, nullPos);

if (distance <= ; distanceThreshold) {
=C2=A0 =C2=A0 distanceMult =3D (Math.log(distance= Threshold / distance)) * moveAwayMult;
=C2=A0 =C2=A0 delta =3D nullPos -= p;
=C2=A0 =C2=A0 nDelta =3D (normalize(delta));
=C2=A0 =C2=A0 newPos= =3D p - nDelta * distanceMult;
} else {
=C2=A0 =C2=A0 p
}<= br>

About a decade ago, ways of doing this abounded on the interwebz...
those links have since passed on. Character Animator has a physics
engine I may explore.
