Help Using Help Reference Back 22 The hierarchy of objects in scripting corresponds to the hierarchy in the user interface. The Application contains a Project window that contains a Composition with a Layer. The source for the Layer can be a footage file, placeholder, or solid, and it is also listed in the Project window. The Layer in turn contains settings known as Properties, and these can hold individual keyframes. The Render Queue contains Render Queue Items as well as Render Settings and Output Modules. All of these rules are directly analogous to scripting. Attributes and properties Note that in ECMAScript and JavaScript, a named piece of data of a certain type is commonly referred to as a property. However, After Effects already has a separate definition of a "property": It is a specific editable value within a layer. Therefore in this section the synonymous term "attribute" refers to these same pieces of data. Global functions This section describes globally available functions that are specific to After Effects. Any JavaScript object or function can call the functions in this section. Using Help Back 22
