Reference for Objects, Methods, Attributes, and Globals

The remainder of this chapter lists and describes all predefined identifiers recognized by After Effects.

These extensions to ECMAScript are organized within a hierarchy of objects which corresponds closely to how they are organized in the application itself. As you look through this A-Z reference section, you can refer to the following diagram for an overview of where the various objects fall within the hierarchy.

Please make particular note of the fact that Item is an object with subclasses that inherit their attributes and methods and add more of their own.


This chart depicts the hierarchy of objects in After Effects scripting. Each object is described in detail in this chapter.
