it’s definitely cool that you’re providing feedback in my comments. i appreciate it. keeps me honest. i’m trying to learn this stuff as well. and don’t worry, i like to keep things light/irreverent around here. (Que Es Span Null, anyone? )

I don’t think Math.random() can hit 1 (this snippet might convince you http://www.nabscripts.com/Forum/Scripts/rd_test.txt ) but it’s always hard to check these sort of things in practice.

You are my “scripting teacher” (or guru if you prefer), I wasn’t blaming you ! just a little suggestion with a bit of humor to participate in your blog.

i think i was using the original code because the reference for Math.random() i had used said it wouldn’t hit 1, but checking a more authoritative source, it can.

i tried your snippet (thanks for that!), but couldn’t get it to place layers at the top/bottom when using Selected Layers in Comp mode. here’s a proposed solution that should handle situations 1 and 2 a little better…

var lIndex;
for (var i=0; i<layers.length; i++)
{
do
{
lIndex = 1 + Math.round(Math.random() * (comp.numLayers - 1));
}
while (lIndex == layers[i].index);
if (Math.random() > 0.5)
layers[i].moveBefore(comp.layer(lIndex));
else
layers[i].moveAfter(comp.layer(lIndex));
}


what do you think?

(and, yes, i am often surprised/embarrassed at where i find snippets of my code.)
