Ask Your Expressions and Scripting Questions Here.

It has been requested in various threads now, that I make an expressions sticky thread. So here it is.

For those of you that don’t know, expression language is a Javascript based language that After Effects uses to make simple (or complicated) dynamic relationships between comps, layers, and properties. It can take your After Effects to another dimension, and it’s particularly useful for templates. Making complex templates easy to organise and customise for less experienced users is easy with expressions.

I might add a few scripting bits and pieces in here too. Scripting is also a very powerful way of extending After Effects capabilities. More powerful than expressions, in fact, because scripting can automate most of what the user can do in Ae. But because scripting is a much more complicated beast, most of this thread will be dedicated to expressions.

Above all, the point of this thread is to collect the answers to those frequently asked questions on the forums. Some buyers might find it useful, but it’s basically aimed at Videohive authors.

Like the Essential Resources thread, I’ll collect the best stuff in this post. I’ll edit and format the best responses and then link to them from this post as a kind of expressions knowledge-base. Please make sure to format any code you post inside “pre” tags.

Well we need some questions first! Expression questions usually pop up at a rate of about 1 a week, so you shouldn’t have to wait for long.

I’ll start with a simple one. :)

I am assuming it is beyond the power of an expression but no matter, for conversation’s sake – can I control a layer’s attributes like the 3D box, motion blur and shy layer switch? Would be e nice one.
