Rotation and trigger expression rig

Hi, I’ve uploaded a project to help. I’m trying to build a rig. Basically I have 24 pre-comped layers in a circular pattern parented to a null so I can rotate as a whole. They need to stay up right. I have that expression part done.

As the layer enters the tigger box (range) I need that one layer in the box to scale up slightly to 75 and move in the positive x position slightly. Adjustable by slider in a controller null. I have the scale expression working. Id also like to trigger a prebuilt animation within the preComp.

My issue currently is the position translation in the x axis. The expression works sort of until I rotate 180 degrees these layers move in the opposite direction and in the Y axis which I don’t want.

I have not started on how I would go about triggering the prebuilt animation in the pre-comp.

any tips would be much appreciated.

Scale expression:

trigger = thisComp.layer(“TRIGGER”);

p1 = toComp(anchorPoint);

p2 = trigger.toComp(trigger.anchorPoint);

d = length(p1, p2);

r = trigger.effect(“Range”)(“Slider”);

maxS = trigger.effect(“Max Scale”)(“Slider”);

minS = 50;

s = ease(d, 0, r, maxS, minS);

if (d > r) s = minS;

[s, s]

Position expression:

trigger = thisComp.layer(“TRIGGER”);

p1 = toComp(anchorPoint);

p2 = trigger.toComp(trigger.anchorPoint);

d = length(p1, p2);

r = trigger.effect(“Range”)(“Slider”);

maxO = trigger.effect(“Max Offset”)(“Slider”);

o = ease(d, 0, r, maxO, 0);

if (d > r) o = 0;

[value[0] + o, value[1]]
