Nodes
-----
Nodes can't be directly exported. Instead you need to export
a node path, then use that node path with `get_node()`
Since Godot 4.0, nodes can be directly exported as properties in a script
without having to use NodePaths:
::
# Allows any node.
@export var node: Node
# Allows any node that inherits from BaseButton.
# Custom classes declared with `class_name` can also be used.
@export var some_button: BaseButton
Exporting NodePaths like in Godot 3.x is still possible, in case you need it:
::
@export var node_path: NodePath
var node = get_node(node_path)
If you want to limit the types of nodes, you can use the @export_node_path annotation.
If you want to limit the types of nodes for NodePaths, you can use the
:ref:`@export_node_path<class_@GDScript_annotation_@export_node_path>`
annotation:
