ae text animator target text
hi i was wondering if there is a way to use the text animator to animate from one sentence to another, going through unicode(?).
im imagining if the the first letter is a it goes through the alphabet the reach the target letter in that position…maybe there is an easier way than expressions and im not getting it..
thanks,
chris

Yes, in theory that’s possible with a text-animator with expression selector that controls “Character offset”. The sentences would need to have the same amount of characters.
One thing you’ll run into is that spaces get ignored by the character offset animators… they always stay a space. Bummer. Unfortunately it extends to all kinds of spaces, so there’s no fooling the animator by replacing spaces with more exotic variations such as em-spaces or non-breaking-spaces etc.
The only workaround would be to substitute the spaces with underscores, or macron-characters, and then do an extra animator that sets the opacity of those characters to 0, if they haven’t already morphed… You can see that’s spiralling into something complex rather quickly.
It’s maybe easier to do it with an expression on the sourceText instead of an animator though.
For example:
str1= "From bedrooms to";
str2= "to broken hearts";
output="";
for (i=0; i<str1.length; i++) {
c1=str1.codePointAt(i);
c2=str2.codePointAt(i);
anim=linear(time-i/str1.length, 1,2, c1,c2)
output += String.fromCodePoint(Math.floor(anim));
}
output;
