EditorScenePostImport
=====================

**Inherits:** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Post-processes scenes after import.

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

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

Imported scenes can be automatically modified right after import by setting their **Custom Script** Import property to a ``tool`` script that inherits from this class.

The :ref:`post_import<class_EditorScenePostImport_method_post_import>` callback receives the imported scene's root node and returns the modified version of the scene. Usage example:

::

    tool # Needed so it runs in editor
    extends EditorScenePostImport
    
    # This sample changes all node names
    
    # Called right after the scene is imported and gets the root node
    func post_import(scene):
        # Change all node names to "modified_[oldnodename]"
        iterate(scene)
        return scene # Remember to return the imported scene
    
    func iterate(node):
        if node != null:
            node.name = "modified_" + node.name
            for child in node.get_children():
                iterate(child)

Method Descriptions
-------------------

.. _class_EditorScenePostImport_method_get_source_file:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_source_file** **(** **)** |const|

Returns the source file path which got imported (e.g. ``res://scene.dae``).

.. rst-class:: classref-item-separator

----

.. _class_EditorScenePostImport_method_get_source_folder:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_source_folder** **(** **)** |const|

Returns the resource folder the imported scene file is located in.

.. rst-class:: classref-item-separator

----

.. _class_EditorScenePostImport_method_post_import:

.. rst-class:: classref-method

:ref:`Object<class_Object>` **post_import** **(** :ref:`Object<class_Object>` scene **)** |virtual|

Called after the scene was imported. This method must return the modified version of the scene.

.. |virtual| replace:: :abbr:`virtual (This method should typically be overridden by the user to have any effect.)`
.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
.. |vararg| replace:: :abbr:`vararg (This method accepts any number of arguments after the ones described here.)`
.. |static| replace:: :abbr:`static (This method doesn't need an instance to be called, so it can be called directly using the class name.)`
