Keywords and Constants
 
 
 

Use the keyword frame in an expression to get the value of the current frame number in your animation. This allows you to create an animation by specifying how a value changes over a sequence of frames.

Use the constant PI instead of the literal numeric value of p (3.1416...).

NoteKeywords and constant names are case-sensitive.
