.. _class_VisualScriptNode_signal_ports_changed:

- **ports_changed** **(** **)**

Emitted when the available input/output ports are changed.

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

.. _class_VisualScriptNode_method_get_default_input_value:

- :ref:`Variant<class_Variant>` **get_default_input_value** **(** :ref:`int<class_int>` port_idx **)** |const|

Returns the default value of a given port. The default value is used when nothing is connected to the port.

----

.. _class_VisualScriptNode_method_get_visual_script:

- :ref:`VisualScript<class_VisualScript>` **get_visual_script** **(** **)** |const|

Returns the :ref:`VisualScript<class_VisualScript>` instance the node is bound to.

----

.. _class_VisualScriptNode_method_ports_changed_notify:

- void **ports_changed_notify** **(** **)**

Notify that the node's ports have changed. Usually used in conjunction with :ref:`VisualScriptCustomNode<class_VisualScriptCustomNode>` .

----

.. _class_VisualScriptNode_method_set_default_input_value:

- void **set_default_input_value** **(** :ref:`int<class_int>` port_idx, :ref:`Variant<class_Variant>` value **)**

Change the default value of a given port.
