Signals
-------

.. _class_VisualScript_signal_node_ports_changed:

- **node_ports_changed** **(** :ref:`String<class_String>` function, :ref:`int<class_int>` id **)**

Emitted when the ports of a node are changed.

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

A script implemented in the  Visual Script programming environment. The script extends the functionality of all objects that instance it.

: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.

You are most likely to use this class via the Visual Script editor or when writing plugins for it.
