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

In GDScript, functions are not *first-class objects*. This means it is impossible to store them directly as variables, return them from another function, or pass them as arguments.

However, by creating a :ref:`FuncRef<class_funcref>` using the :ref:`@GDScript.funcref<class_@GDScript_funcref>` function, a reference to a function in a given object can be created, passed around and called.

Member Function Description
---------------------------

.. _class_FuncRef_call_func:

- :ref:`Variant<class_variant>`  **call_func**  **(** **)** vararg

.. _class_FuncRef_set_function:

- void  **set_function**  **(** :ref:`String<class_string>` name  **)**

Set the name of the function to call on the object, without parentheses or any parameters.

.. _class_FuncRef_set_instance:

- void  **set_instance**  **(** :ref:`Object<class_object>` instance  **)**

Set the object on which to call the referenced function. This object must be of a type actually inheriting from :ref:`Object<class_object>`, not a built-in type such as :ref:`int<class_int>`, :ref:`Vector2<class_vector2>` or :ref:`Dictionary<class_dictionary>`.
