Slider to Play through keyframe data
Hi all,
I’m animating flashing opacity effects which I want to happen across a slider 0-1.
So I have the flashing keyframe data (1-10 keys) on a separate layer’s opacity.How do I playthrough each keyframes data as the slider progresses through 0 – 1?
Thanks!

try this, just point the effect correctly to the proper slider
valueAtTime(linear(thisComp.layer("target layer").effect("Slider")(1),0,1,key(1).time,key(numKeys).time))Alex Printz

It’s good, thank you!
But I’m struggling to grab the keyframe information from a different layer when using the normal reference methods. How do I target my “opa” correctly in this instance below?
row = effect("Row")("Slider");
drop = thisComp.layer("CTRL").effect("Drop")("Slider");
thedrop = linear(drop,row-1,row,0,1); //converts row vs drop to 0 to 1
opa = thisComp.layer("Col A Row 1").transform.opacity //reference layers opacityvalueAtTime(linear(thedrop,0,1,key(1).time,key(numKeys).time))

I think it would be like this:
row = effect("Row")("Slider");
drop = thisComp.layer("CTRL").effect("Drop")("Slider");
thedrop = linear(drop,row-1,row,0,1); //converts row vs drop to 0 to 1
opa = thisComp.layer("Col A Row 1").transform.opacity //reference layers opacityvalueAtTime(linear(thedrop,0,1,opa.key(1).time,opa.key(opa.numKeys).time))

Many thanks Alex!
That was nearly right, just needed another reference to the layer at the start! Phew! 😀opa = thisComp.layer("Col A Row 1").transform.opacity //reference layers opacityopa.valueAtTime(linear(slider,0,1,opa.key(1).time,opa.key(opa.numKeys).time))
