Stops the function execution and returns the current suspended state to the calling function.
From the caller, call [method GDScriptFunctionState.resume] on the state to resume execution. This invalidates the state. Within the resumed function, [code]yield()[/code] returns whatever was passed to the [code]resume()[/code] function call.
If passed an object and a signal, the execution is resumed when the object emits the given signal. In this case, [code]yield()[/code] returns the argument passed to [code]emit_signal()[/code] if the signal takes only one argument, or an array containing all the arguments passed to [code]emit_signal()[/code] if the signal takes multiple arguments.
+ You can also use [code]yield[/code] to wait for a function to finish:
+ [codeblock]
+ func _ready -> void:
+ yield(do_something(), "completed")
+ yield(do_something_else(), "completed")
+ print("All functions are done!")
+
+ func do_something():
+ print("Something is done!")
+
+ func do_something_else():
+ print("Something else is done!")
+
+ # prints:
+ # Something is done!
+ # Something else is done!
+ # All functions are done!
+ [/codeblock]
+ When yielding on a function, the [code]completed[/code] signal will be emitted automatically when the function returns. It can, therefore, be used as the [code]signal[/code] parameter of the [code]yield[/code] method to resume.
+ If you are planning on calling the same function within a loop, you should consider using [code]yield(get_tree(), "idle_frame")[/code] also.
