Split letters from source text and randomize
Hi guys,
I’m not that good with expressions, and I would like to do the following.
I would like to split every letter from a word, and then show each letter every 5 frames. I know how to split the word, and just show 1 letter from it, but now I want each letter to show every 5 frames (and loop maybe).
I got this so far in my Source text:
letters = “design”;
split_letters = letters.split(“”)[0];So this shows the first letters, [1] would be the seconds, and so on. I think I have to count the total letters, and output that split_letters, and then add a time interval.
Thanks!

Since a string is already treated as a array, you don’t need to split it. This should work:
letters = “design”;
dur = 5; // frames per letter
idx = Math.floor(timeToFrames(time)/dur)%letters.length;
letters[idx]Dan

Thanks Dan! Works perfect!

Another question, how do I start the script at a specific frame, for example frame 15?
Sliding the layer in time doesn’t work. I tried adding this, but that doesn’t work neither.if (time > .6) {
letters = “design”;
dur = 7; // frames per letter
idx = Math.floor(timeToFrames(time)/dur)%letters.length;
letters[idx];
}The generated character are linked to an animation that starts at frame 15. So it starts with the letter s and not d, it skips the first two characters.

Maybe like this:
tStart = 15*thisComp.frameDuration;
if (time > tStart) {
letters = “design”;
dur = 7; // frames per letter
idx = Math.floor(timeToFrames(time-tStart)/dur)%letters.length;
letters[idx];
}else “”Dan

Thanks Dan, I will try that.
I kind of fixed it for now with this
letters = “design”;
dur = 7; // frames per letter
idx = Math.floor(timeToFrames(time – framesToTime(15))/dur)%letters.length;
if (time > framesToTime(15))
letters[idx]
else
letters[0]This shows the first letter until the animation starts.
