Random character opacity on and off

[Jessica Lawheed]

In V 18.4.1 I am getting an error saying there is a “SyntaxError unexpected token ‘else'”. Any fixes for this?

If it’s the most recent expression, you probably just need to replace this:

if ((time-inPoint) < myReveal) 100 else 0

with this:

(time-inPoint) < myReveal ? 100 : 0

Hi there I know this is from a long time ago, I was wondering if you could tell me a way of altering this expression to make the opacity fade or ramp as the characters randomly fade on and off. Thank you very much

Hi there I know this is been a long long time since the post. But I would like to use this expression however is it possible to ramp the opacity of the characters? If you could please let me know thank you.

It depends on which expression you mean, but with the latest one, you could do something like this:

revealTime = 3; // reveal over 3 seconds
fadeTime = .5;
seedRandom(textIndex,true);
myReveal = random(revealTime);
linear((time-inPoint), myReveal, myReveal+fadeTime, 100, 0)

or maybe switch the last line to this:

linear((time-inPoint), myReveal, myReveal+fadeTime, 0, 100)

depending on whether you want the letters to fade in or out.
