XML components overview

An XML-based markup language has been added to the SceneGraph API that allows new SceneGraph components to be defined consisting of a set of SceneGraph nodes loaded from a declarative description, with interactive or animated behaviors added using Brightscript, similar to how HTML and Javascript are used in web development.

Once a XML component has been defined, it can be used just like any of the built-in SceneGraph node types. For example, if a XML component named Gizmo has been defined, an instance of the component can be created by either declaring it in another XML component file:

<Gizmo id="MyGizmo" />

Or using the createObject() function to create an roSGNode object:

createObject("roSGNode", "Gizmo")

Each component XML file defines a top-level <component> XML element that may contain an <interface> element, zero or more <script> elements, and zero or more elements defining child SceneGraph nodes.
