			<argument index="0" name="object" type="Object" default="null">
			</argument>
			<argument index="1" name="signal" type="String" default="&quot;&quot;">
			</argument>
			<description>
				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():
				    yield(countdown(), "completed") # waiting for the countdown() function to complete
				    print('Ready')

				func countdown():
				    yield(get_tree(), "idle_frame") # returns a GDScriptFunctionState object to _ready()
				    print(3)
				    yield(get_tree().create_timer(1.0), "timeout")
				    print(2)
				    yield(get_tree().create_timer(1.0), "timeout")
				    print(1)
				    yield(get_tree().create_timer(1.0), "timeout")

				# prints:
				# 3
				# 2
				# 1
				# Ready
				[/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.
				In order to yield on a function, the resulting function should also return a [code]GDScriptFunctionState[/code]. Notice [code]yield(get_tree(), "idle_frame")[/code] from the above example.
