Gets the property of a node using a NodePath

get_node_property.gd

# This is an awful solution, but NodePath is missing an important method, so there's no great alternative that I've found.
# Try me with get_node_property(self, "Control/Spatial/CollisionShape2D:shape:extents:x")

func get_node_property(from: Node, path: NodePath):
    assert ":" in path as String  # Causes a hard crash
    path = path as NodePath
    var node_path = get_as_node_path(path)
    var property_path = (path.get_concatenated_subnames() as NodePath).get_as_property_path()
    return from.get_node(node_path).get_indexed(property_path)

func get_as_node_path(path: NodePath) -> NodePath:
    assert ":" in path as String
    path = path as NodePath
    var node_path = path as String
    var property_path = path.get_concatenated_subnames() as String
    node_path.erase((path as String).length() - property_path.length() - 1, property_path.length() + 1)
