Alpply while/do loop to a text layers, see no characters… why?

[Dan Ebberts]

It looks like there are some extra spaces in there. Try it this way:


posterizeTime(3);
var myText = "";
i = 0;
while(i < 500)
{
var randomNumber = random( 48 , 122);
myText += String.fromCharCode(randomNumber);
i++;
}
myText

still dont work

[Assaf Goldlust]

i tried to do that with the code you wrote.
but i still got the same result.
please, i really need to understand why it doesn’t work and how to fix it

[Dan Ebberts]

I just copied and pasted that code into the Source Text property of a text layer and it works as I would expect it to. What happens when you do that?

That’s strange. So if you start with a text layer that has actual text, then apply the expression, same result?

Dan

[Assaf Goldlust]

yes, still same result 🙁

[Assaf Goldlust]

it might be important to note:
its happend to me also on another computer with a diffrent version of after effect.

so i think we can rule out the possibility of a bug

[Dan Ebberts]

Can you post a simple project file demonstrating the problem?

Dan

[Assaf Goldlust]

Actually i was able to make it work.
i dont knkw why yet but appearently its working great when im doing it on my CS6 version.
so the problem is not with the expression.

but there is another thing i wish to understand.
in the book he stated that for this expressions

my text need to have this variable

var myText = "";


but i still need to know why?
