Description
-----------
Calling :ref:`@GDScript.yield<class_@GDScript_yield>` within a function will cause that function to yield and return its current state as an object of this type. The yielded function call can then be resumed later by calling :ref:`resume<class_GDScriptFunctionState_resume>` on this state object.
Member Function Description
---------------------------
.. _class_GDScriptFunctionState_is_valid:
- :ref:`bool<class_bool>` **is_valid** **(** :ref:`bool<class_bool>` extended_check=false **)** const
Check whether the function call may be resumed. This is not the case if the function state was already resumed.
If ``extended_check`` is enabled, it also checks if the associated script and object still exist. The extended check is done in debug mode as part of :ref:`GDScriptFunctionState.resume<class_GDScriptFunctionState_resume>`, but you can use this if you know you may be trying to resume without knowing for sure the object and/or script have survived up to that point.
.. _class_GDScriptFunctionState_resume:
- :ref:`Variant<class_variant>` **resume** **(** :ref:`Variant<class_variant>` arg=null **)**
Resume execution of the yielded function call.
If handed an argument, return the argument from the :ref:`@GDScript.yield<class_@GDScript_yield>` call in the yielded function call. You can pass e.g. an :ref:`Array<class_array>` to hand multiple arguments.
This function returns what the resumed function call returns, possibly another function state if yielded again.
