The component to associate with the object. The component class must adopt the protocol specified in the
The protocol whose functionality the component provides.
Components are the basis for customizable file format and object graph support in Model I/O. By default, the
MDLObject uses the
MDLTransform protocols to model object hierarchies and spatial transforms: When you load an object graph from a
MDLAsset instance, Model I/O creates container and transforms components to represent the object hierarchy and spatial relationships described in the asset file. However, you can also create custom components. For example, a custom component protocol could add support for an asset format that encodes gameplay-related information such as scripting triggers, or a custom class for the
MDLObject could implement other ways to store or traverse object hierarchies.
