  22. Description
  23. -----------
  24. 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_GDFunctionState_resume>` on this state object.

  29. Check whether the function call may be resumed. This is not the case if the function state was already resumed.
  30. 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:`GDFunctionState.resume<class_GDFunctionState_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.
  31. .. _class_GDFunctionState_resume:
  32. - :ref:`Variant<class_variant>` **resume** **(** :ref:`Variant<class_variant>` arg=null **)**
  33. Resume execution of the yielded function call.
  34. 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.
  35. This function returns what the resumed function call returns, possibly another function state if yielded again.
