SceneState
==========

**Inherits:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Provides access to a scene file's information.

.. rst-class:: classref-introduction-group

Description
-----------

Maintains a list of resources, nodes, exported and overridden properties, and built-in scripts associated with a scene. They cannot be modified from a **SceneState**, only accessed. Useful for peeking into what a :ref:`PackedScene<class_PackedScene>` contains without instantiating it.

This class cannot be instantiated directly, it is retrieved for a given scene as the result of :ref:`PackedScene.get_state<class_PackedScene_method_get_state>`.
