Blink word in sentence

[Dan Ebberts]

One way:

Add an Opacity Animator and set the Opacity value to 0.
Add an Expression Selector and delete the Range Selector.
Set the Based On parameter to “Words”
Add an expression like this to Amount parameter:


wordIndexToBlink = 3;
freq = 1;

if (textIndex == wordIndexToBlink){
seg = Math.floor((time - inPoint)*freq*2);
if (seg%2) 100 else 0
}else 0

Works like a charm! Thanks! I didn’t even know text had a parameter for expressions like that.

Would it be possible to add a “blink x number of times, then stay solid” feature into that?

[Dan Ebberts]

Like this:


wordIndexToBlink = 3;
numBlinks = 5;
freq = 1;
if (textIndex == wordIndexToBlink){
seg = Math.floor((time - inPoint)*freq*2);
if (seg < numBlinks*2)
if (seg%2) 100 else 0
else
0
}else
0

Ok, I’m impressed! So cool!

Just curious is it possible for wordIndexToBlink to contain more than one value?

Like:

wordIndexToBlink = 1,5 (words 1 and 5)
or
wordIndexToBlink = 2~4 (words 2 through 4)

[Dan Ebberts]

One way:


wordIndexToBlink = [2,3,4];
numBlinks = 5;
freq = 1;
blinkMe = false;
for (i = 0; i < wordIndexToBlink.length; i++){
if (wordIndexToBlink[i] == textIndex){
blinkMe = true;
break;
}
}
if (blinkMe){
seg = Math.floor((time - inPoint)*freq*2);
if (seg < numBlinks*2)
if (seg%2) 100 else 0
else
0
}else
0

I am using after effects 2019 but when I used the expressions mentioned here..i got a wrong message and I couldn’t solve it…
Syntax Error: Unexpected token else

[Dan Ebberts]

Try changing this line:

if (seg%2) 100 else 0

to this:

(seg%2) ? 100 : 0

I got a different mistake message

Syntax Error :Unexpected token ?

[Dan Ebberts]

What does your expression look like now?
