How to randomly change color of characters

[Dan Ebberts]

It should work fine in CS6 (in fact, I’m almost sure that’s where I tested it).

When I apply this expression to Fill Color RGB I get the warning:

Class ‘global’ has no property or method named ‘textIndex’

Am I not applying it to the right parameter?

[Dan Ebberts]

That expression is for the Amount parameter of the Expression Selector. You should read the whole thread (if you haven’t already).

I still get “no property or method named ‘text index'”

[Dan Ebberts]

You should be using textIndex

[Riccardo Sinti]

I am. My typo was in the post not the expression.

[Dan Ebberts]

How about posting the entire expression?

[Riccardo Sinti]

Its this, from the thread:

seedRandom(textIndex,true);
palette = [[100,0,0],[0,100,0],[0,0,100],[0,100,100],[100,0,100],[100,100,0],[100,50,0]];
// [red,blue,green,cyan,magenta,yellow,orange]
idx = Math.floor(random(palette.length));
palette[idx]

Hmm… I guess I’m stumped. If you have that pasted into the Amount property of your Expression Selector, you shouldn’t get that message. I just pasted in what you posted and it works for me.

You will get that error though if you past an expression containing textIndex into any other property besides the Amount property.
