a slider to trim them all
hi!
I have a lot of shape layers, and want to make their strokes grow sequentially, so using trimming paths, when I have one path grown, I want next shape layer to grow, and so on.. I could keyframe them all, but as I have a lot of shape layers, controlling and refining all the generated keys can be a pain..
So, my question….
is it possible to make a null, add a slider (or 2, one called “end” and another called “)start”, and make that slider control all that as a whole? so, as I increase the slider`s value, first shape layer grows, and when it ends to grow shape layer 2 starts growing, and so on
basically: make it act as if all shapes where inside a same shape layer`s group and then adding trim paths to trim them sequentially…many thanks in advance!

Assuming your slider is on “Null 1” and your first 10 layers are participating shape layers, something like this should work:
firstShapeLayer = 1;
lastShapeLayer = 10;
sliderRange = 100;
s = thisComp.layer(“Null 1”).effect(“Slider Control”)(“Slider”);numSegs = lastShapeLayer-firstShapeLayer+1;
segRange = sliderRange/numSegs;
myIdx = index-firstShapeLayer;
myStart = myIdx*segRange;
myEnd = (myIdx+1)*segRange;
linear(s,myStart,myEnd,0,100)Dan
