See the objects and functions you use to control the node tree's composition.
You create the node tree by creating parent-child relationships between nodes. Each node maintains an ordered list of children, referenced by reading the node’s
children property. The order of the children in the tree affects many aspects of scene processing, including hit testing and rendering, so it's important to organize the node tree appropriately.
When you need to directly traverse the node tree, you use the properties in the following table to uncover the tree’s structure.
The array of
If the node is a child of another node, this property holds the parent. Otherwise, it holds
If the node is included anywhere in a scene, this property returns the scene node that is the root of the tree. Otherwise it holds
