  13. Description
  14. -----------
  15. A class stored as a resource. A script extends the functionality of all objects that instantiate it.
  16. This is the base class for all scripts and should not be used directly. Trying to create a new script with this class will result in an error.
  17. 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.

  166. \ **Note:** If a script does not have source code, this does not mean that it is invalid or unusable.
