Scripting tip.

For formulas this little trick may make some things easier.

Ruby has what is called a "short if". If you have a formula like:

if(frame==0);1;else;0;end

You could also do the same thing like this:

frame==0? 1:0

That basically means
<if>frame==0? <then> 1 :<else> 0 <end>

The "?" takes the place of the "if" and the ":" takes the place of "else". You dont need ";"'s or "end"

Its a lot shorter. But not always as clear so its a trade off.
