Scroll text with scale if/else
I am breaking my mind to find how and I research here and can’t find the solution. I hope be clear here. ☺
I have a comp with 700px width, and 5 words align in x. But I want when that words pass between 270px and 400px of this comp scale to 100 them back to 75% when out this position. Ok I did for wich one separately(in this expression I put here), my question is: Can I put a Null and then this 5 words follow this null then they pass between this values they scale?
My doubt is the value of x position the word is replace of de null, so the null will pass just one time in 270 and 400px.Thank you!

p = transform.position[0];if(p > 270 && p< 400){
[100,100];
}else{
[75,75];

Try this:
p = toComp(anchorPoint)[0];
if (p > 270 && p < 400)
[100,100]
else
[75,75]

Dan, you are a genius!!
This “toComp(anchorPoint)[0]” say to layer look his on anchor point?
Thanks,

toComp() converts from layer space to comp space. A layer’s Anchor Point is always represented in layer space, so that’s what you need to use. You only need to use toComp() if the layer has a parent.

Just one more question,
To scale change smooth, not like a hold keyframe? I need to create a variable to replace the 270?
Thanks

Maybe something more like this:
pMin = 270;
pMax = 400;
pMid = (pMin+pMax)/2;
p = toComp(anchorPoint)[0];
if (p < pMid)
ease(p,pMin,pMid,[75,75],[100,100])
else
ease(p,pMid,pMax,[100,100],[75,75])
