The block to apply to the node’s child and descendant nodes.
The block takes two parameters:
The child node currently being evaluated.
A reference to a Boolean value. Set
YESin the block to abort further processing of the child node subtree.
SceneKit uses a recursive preorder traversal to process the child node subtree—that is, the block runs for a node before it runs for each of the node’s children, and it processes all children of a node before processing any of that node’s sibling nodes.
This method is equivalent to the
enumerate method, but unlike that method it also runs the block to process the node itself, not just its child nodes.
