InstancePlaceholder
===================

**Inherits:** :ref:`Node<class_Node>` **<** :ref:`Object<class_Object>`

Placeholder for the root :ref:`Node<class_Node>` of a :ref:`PackedScene<class_PackedScene>`.

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

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

Turning on the option **Load As Placeholder** for an instantiated scene in the editor causes it to be replaced by an **InstancePlaceholder** when running the game, this will not replace the node in the editor. This makes it possible to delay actually loading the scene until calling :ref:`create_instance<class_InstancePlaceholder_method_create_instance>`. This is useful to avoid loading large scenes all at once by loading parts of it selectively.

The **InstancePlaceholder** does not have a transform. This causes any child nodes to be positioned relatively to the :ref:`Viewport<class_Viewport>` from point (0,0), rather than their parent as displayed in the editor. Replacing the placeholder with a scene with a transform will transform children relatively to their parent again.

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

.. _class_InstancePlaceholder_method_create_instance:

.. rst-class:: classref-method

:ref:`Node<class_Node>` **create_instance**\ (\ replace\: :ref:`bool<class_bool>` = false, custom_scene\: :ref:`PackedScene<class_PackedScene>` = null\ ) :ref:`🔗<class_InstancePlaceholder_method_create_instance>`

Call this method to actually load in the node. The created node will be placed as a sibling *above* the **InstancePlaceholder** in the scene tree. The :ref:`Node<class_Node>`'s reference is also returned for convenience.

\ **Note:** :ref:`create_instance<class_InstancePlaceholder_method_create_instance>` is not thread-safe. Use :ref:`Object.call_deferred<class_Object_method_call_deferred>` if calling from a thread.

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

.. _class_InstancePlaceholder_method_get_instance_path:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_instance_path**\ (\ ) |const| :ref:`🔗<class_InstancePlaceholder_method_get_instance_path>`

Gets the path to the :ref:`PackedScene<class_PackedScene>` resource file that is loaded by default when calling :ref:`create_instance<class_InstancePlaceholder_method_create_instance>`. Not thread-safe. Use :ref:`Object.call_deferred<class_Object_method_call_deferred>` if calling from a thread.

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

.. _class_InstancePlaceholder_method_get_stored_values:

.. rst-class:: classref-method

:ref:`Dictionary<class_Dictionary>` **get_stored_values**\ (\ with_order\: :ref:`bool<class_bool>` = false\ ) :ref:`🔗<class_InstancePlaceholder_method_get_stored_values>`

Returns the list of properties that will be applied to the node when :ref:`create_instance<class_InstancePlaceholder_method_create_instance>` is called.

If ``with_order`` is ``true``, a key named ``.order`` (note the leading period) is added to the dictionary. This ``.order`` key is an :ref:`Array<class_Array>` of :ref:`String<class_String>` property names specifying the order in which properties will be applied (with index 0 being the first).

.. |const| replace:: :abbr:`const (This method has no side effects. It doesn't modify any of the instance's member variables.)`
