I have around 90 layers with an opacity expression that, for a capital Z layer reads

“v = parseInt(thisComp.layer(“UNICODE”).text.sourceText);

if (v==90)100 else 0;”

but for lowercase a layer, reads

v = parseInt(thisComp.layer(“UNICODE”).text.sourceText);

if (v==115)100 else 0;

Etc. The “UNICODE” text layer updates to provide the unicode digits for the last letter to get revealed in a type-on style text animation, (so when it is 90, only the capital Z layer is visible, and when it is 115, only the lowercase a layer is visible).

So if I’d write the word PiZZaZ, then the P layer reveals, then the i layer, then the Z layer reveals, then the a layer, then the Z layer again. I’d prefer it if the P layer reveals, then the i layer, then the Z layer reveals, the the Z layer reveals AGAIN, then the a layer, then the Z layer again.

Would there be a way of handling that in the expressions without having 90 “&&” moments in each expression?

Thanks very much for your time

Incredible. Would never have thought to do it like that. Thank you so much.

The relative indexing is exactly what I was looking for. Mr. Ebberts, you’ve done it again.

Figured it out. Just used the modulus operator (%). Used the ratio of the base x value and the cycled x value to determine the y.

xbase = 60+120*(index-1); x =60+120*(index-1)%1920; y = 60+((xbase-x)/1920)*120;
[x,y]

Yeah I’d only found it it after posting my question. I still don’t quite understand why an input of 0 gives me an offset position of +11, but I haven’t yet worked out that math.

But thanks for your time.

Ah, bummer. Thanks for the insight Dan (this, and everything else over the years). Cheers.
