Single Random letters using specific letters?
i am trying to make each letter in the word ALLEGORY randomize with letters and numbers.I want to restrict the random letters used to the letters in the word ALLEGORY and mix with random numbers.
i dont have too much experience with expression and don’t really know where to start =P

Is there more to it than that? I mean, say you end up with “Y9GGE517”–is that all you need, a static string?

Pretty much. trying to do a matrix-y thing with ALLEGORY. it could be A48GL8Y1 or what ever while its running but i generally want to restrict it to the letters in ALLEGORy

>while its running…
Ah. You haven’t described that part. What is it that you have in mind?

So pretty much, the word ALLEGORY will display and then each letter in the word ALLEGORY will cycle through random numbers and only the letters in the word ALLEGORY.
EXAMPLE:
the first letter (A) would cycle randomly through the letters, A, L, E, G, O, R, and Y and the numbers 0-9.and so on, for the rest of the letters in the word ALLEGORY. and then end with ALLEGORY again? get it now?

Probably not. Here’s a source text expression that seems like it does what you’re asking for, but I’m guessing it isn’t what you had in mind:
choices = "ALEGORY0123456789";
str = "ALLEGORY";
tStart = 1;
tStop = 3;if (time > tStart && time < tStop){
seedRandom(time,true);
s = "";
for (i = 0; i < str.length; i++){
idx = Math.floor(random(choices.length));
s += choices[idx];
}
}else{
s = str;
}
s

wow! thanks Dan, it works exactly the way i wanted.
is there a way to make it loop?
like after it stops it has like a 1 secon pause and then randomizes again on an infinite loop?

Like this:
choices = "ALEGORY0123456789";
str = "ALLEGORY";
tStart = 1;
tStop = 3;
tStartAgain = 4;if ((time > tStart && time < tStop) || time > tStartAgain){
seedRandom(time,true);
s = "";
for (i = 0; i < str.length; i++){
idx = Math.floor(random(choices.length));
s += choices[idx];
}
}else{
s = str;
}
s

freaking sweet! thank you. one last thing… how would i slow down the random cycling of letters and numbers? its running a tad bit too fast.

One way:
choices = "ALEGORY0123456789";
str = "ALLEGORY";
tStart = 1;
tStop = 3;
cps = 10; // characters per second
tStartAgain = 4;
if ((time > tStart && time < tStop) || time > tStartAgain){
seed = Math.floor(time*cps);
seedRandom(seed,true);
s = "";
for (i = 0; i < str.length; i++){
idx = Math.floor(random(choices.length));
s += choices[idx];
}
}else{
s = str;
}
s
