Signals
-------

.. _class_Object_script_changed:

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

Emitted whenever the script of the Object is changed.


Numeric Constants
-----------------

- **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.

Enums
-----

  .. _enum_Object_ConnectFlags:

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.


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

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

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_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__get_property_list>` and handled in :ref:`_get<class_Object__get>` and :ref:`_set<class_Object__set>`. However, scripting languages and C++ have simpler means to export them.

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

.. _class_Object__get_property_list:

- :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__init:

- void **_init** **(** **)** virtual

.. _class_Object__notification:

- void **_notification** **(** :ref:`int<class_int>` what **)** virtual

- void **add_user_signal** **(** :ref:`String<class_string>` signal, :ref:`Array<class_array>` arguments=[  ] **)**

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_call:

- :ref:`Variant<class_variant>` **call** **(** :ref:`String<class_string>` method **)** vararg

Calls the ``method`` on the object and returns a result. Pass parameters as a comma separated list.

To avoid this, first use :ref:`is_connected<class_Object_is_connected>` to check for existing connections.
