Yes, or they are free’d automatically as the parent is free’d recursively. If you have called `add_child` on a node you created dynamically, godot will handle its lifecycle from there.
If you don’t add a dynamically-created node to the tree, you are responsible for `free`.
That almost never comes up, because I eventually figure out how to decompose everything into a tree Node, or! A Resource.
Resources are managed in a separate memory pool, and don’t need to be added to the tree for godot to take care of it. Go ahead, you just try and `free` a resource! ;)
In the docs for Node.remove_child(Node node)[1] it says
"Removes a child node. The node is NOT deleted and must be deleted manually."
Do you still have to queue_free the top node that was removed from the tree, or else how is it being deleted. Or is there a different method to call for removing it from the tree.
BTW: I really like the `_init` / `_enter_tree` / `_ready` / `_exit_tree` lifecycle as was described.
