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

A class stored as a resource. A script exends the functionality of all objects that instance it.

The ``new`` method of a script subclass creates a new instance. :ref:`Object.set_script<class_Object_method_set_script>` extends an existing object, if that object's class matches one of the script's base classes.

Property Descriptions
---------------------

.. _class_Script_property_source_code:

- :ref:`String<class_String>` **source_code**

+----------+------------------------+
| *Setter* | set_source_code(value) |
+----------+------------------------+
| *Getter* | get_source_code()      |
+----------+------------------------+

The script source code or an empty string if source code is not available. When set, does not reload the class implementation automatically.

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

.. _class_Script_method_can_instance:

- :ref:`bool<class_bool>` **can_instance** **(** **)** const

Returns ``true`` if the script can be instanced.

----

.. _class_Script_method_get_base_script:

- :ref:`Script<class_Script>` **get_base_script** **(** **)** const

Returns the script directly inherited by this script.

----

.. _class_Script_method_get_instance_base_type:

- :ref:`String<class_String>` **get_instance_base_type** **(** **)** const

Returns the script's base type.

----

.. _class_Script_method_has_script_signal:

- :ref:`bool<class_bool>` **has_script_signal** **(** :ref:`String<class_String>` signal_name **)** const

Returns ``true`` if the script, or a base class, defines a signal with the given name.

----

.. _class_Script_method_has_source_code:

- :ref:`bool<class_bool>` **has_source_code** **(** **)** const

Returns ``true`` if the script contains non-empty source code.

----

.. _class_Script_method_instance_has:

- :ref:`bool<class_bool>` **instance_has** **(** :ref:`Object<class_Object>` base_object **)** const

Returns ``true`` if ``base_object`` is an instance of this script.

----

.. _class_Script_method_is_tool:

- :ref:`bool<class_bool>` **is_tool** **(** **)** const

Returns ``true`` if the script is a tool script. A tool script can run in the editor.

----

.. _class_Script_method_reload:

- :ref:`Error<enum_@GlobalScope_Error>` **reload** **(** :ref:`bool<class_bool>` keep_state=false **)**

Reloads the script's class implementation. Returns an error code.
