Signals
-------

.. _class_Object_signal_script_changed:

- **script_changed** **(** **)**

Emitted whenever the script of the Object is changed.

Enumerations
------------

.. _enum_Object_ConnectFlags:

.. _class_Object_constant_CONNECT_DEFERRED:

.. _class_Object_constant_CONNECT_PERSIST:

.. _class_Object_constant_CONNECT_ONESHOT:

.. _class_Object_constant_CONNECT_REFERENCE_COUNTED:

enum **ConnectFlags**:

- **CONNECT_DEFERRED** = **1** --- Connect a signal in deferred mode. This way, signal emissions are stored in a queue, then set on idle time.

- **CONNECT_PERSIST** = **2** --- Persisting connections are saved when the object is serialized to file.

- **CONNECT_ONESHOT** = **4** --- One shot connections disconnect themselves after emission.

- **CONNECT_REFERENCE_COUNTED** = **8**

Constants
---------

.. _class_Object_constant_NOTIFICATION_POSTINITIALIZE:

.. _class_Object_constant_NOTIFICATION_PREDELETE:

- **NOTIFICATION_POSTINITIALIZE** = **0** --- Called right when the object is initialized. Not available in script.

- **NOTIFICATION_PREDELETE** = **1** --- Called before the object is about to be deleted.

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

Base class for all non built-in types. Everything which is not a built-in type starts the inheritance chain from this class.

Objects can be constructed from scripting languages, using ``Object.new()`` in GDScript, ``new Object`` in C#, or the "Construct Object" node in VisualScript.

Objects do not manage memory, if inheriting from one the object will most likely have to be deleted manually (call the :ref:`free<class_Object_method_free>` function from the script or delete from C++).

Some derivatives add memory management, such as :ref:`Reference<class_Reference>` (which keeps a reference count and deletes itself automatically when no longer referenced) and :ref:`Node<class_Node>`, which deletes the children tree when deleted.

Objects export properties, which are mainly useful for storage and editing, but not really so much in programming. Properties are exported in :ref:`_get_property_list<class_Object_method__get_property_list>` and handled in :ref:`_get<class_Object_method__get>` and :ref:`_set<class_Object_method__set>`. However, scripting languages and C++ have simpler means to export them.

Objects also receive notifications (:ref:`_notification<class_Object_method__notification>`). Notifications are a simple way to notify the object about simple events, so they can all be handled together.

Method Descriptions

- :ref:`Array<class_Array>` **_get_property_list** **(** **)** virtual

Returns the object's property list as an :ref:`Array<class_Array>` of dictionaries. Dictionaries must contain: name:String, type:int (see TYPE\_\* enum in :ref:`@GlobalScope<class_@GlobalScope>`) and optionally: hint:int (see PROPERTY_HINT\_\* in :ref:`@GlobalScope<class_@GlobalScope>`), hint_string:String, usage:int (see PROPERTY_USAGE\_\* in :ref:`@GlobalScope<class_@GlobalScope>`).

.. _class_Object_method__init:

Adds a user-defined ``signal``. Arguments are optional, but can be added as an :ref:`Array<class_Array>` of dictionaries, each containing "name" and "type" (from :ref:`@GlobalScope<class_@GlobalScope>` TYPE\_\*).

.. _class_Object_method_call:

- :ref:`Variant<class_Variant>` **call** **(** :ref:`String<class_String>` method **)** vararg

A ``signal`` can only be connected once to a ``method``. It will throw an error if already connected. To avoid this, first use :ref:`is_connected<class_Object_method_is_connected>` to check for existing connections.
