Instance Method

addChild(_:)

Adds a child object to this object, creating a container for the object’s children if necessary.

Declaration

func addChild(_ child: MDLObject)

Parameters

child

The child object to add.

Discussion

Many asset formats describe a hierarchy of transforms that model the spatial relationships between meshes, lights, and cameras in the asset. In such formats, hierarchic transforms are MDLObject instances whose children property references the objects affected by the transform—and those objects can be other MDLObject instances with children of their own.

If the object’s children property is nil, this method sets that property to a new MDLObjectContainer instance before adding the child object.
