oobiekanoobie Your question is really not clear. The code image you posted does not communicate what you want to do and bot's inept response on lambdas only muddied the water more. So try to be more punctual with your question (what exactly are you're trying to accomplish) and post some actual code.

      xyz Okay, here is the code

      extends Control

var textToReveal: String = "This is the text to be revealed"
var STATUS_PROCESS : bool
var STATUS_DONE : bool
var revealInterval: float = 0.05
var visible_letters : int = 0
var pressed_z = 0

func _ready():
	$Timer.wait_time = revealInterval
	STATUS_DONE = true
	STATUS_PROCESS = false

func _input(event):
	if STATUS_DONE == true:
			if event.is_action_pressed("ui_accept"):
				pressed_z += 1
				if pressed_z == 1:
					$Label.text = ""
					visible_letters = 0
					$Timer.start()
					STATUS_DONE = false
					STATUS_PROCESS = true
				elif pressed_z == 2:
					visible_letters = 0
					pressed_z = 0
					STATUS_DONE = true
					$Label.text = ""
	elif STATUS_DONE == false:
		if Input.is_action_just_released("ui_accept"):
			if pressed_z == 1:
				$Label.text = textToReveal
				$Timer.stop()
				STATUS_DONE = true
				STATUS_PROCESS = false
				print("Skipped text")
func _on_timer_timeout():
	if visible_letters < textToReveal.length():
		var letter = textToReveal[visible_letters]
		$Label.text += letter
		if letter != " ":  
			$AudioStreamPlayer.play()
			visible_letters += 1
		elif letter == " ":
			visible_letters += 1
	else:
		STATUS_DONE = true
		print("Printing finished")
		$Timer.stop()

      I am trying to make that a global function, but the downsides are it requires a AudioStreamPlayer, a Label and a Timer. I tried to make it so I make a global variable that integrates the timeout inside the global function and uses variables as nodes. For the Label and AudioStreamPlayer I tried replacements that are working properly but the timer won't work and the lambas thing is a bit confusing. Can I make that whole process into a single function?
      btw, it is for making a dialogue that is written progressively, like in Professor Layton

          I'm not sure why exactly do you need a global function for that.
          Labels have visible_characters property. You can simply animate that (prefferrably with a tween). It'll make the whole thing much easier.

          And please format your code inside proper tags. It's hard to follow it this way.

            And please format your code inside proper tags. It's hard to follow it this way.

            To do that, place ~~~ on lines before and after the code. The </> icon at the bottom of the post is supposed to do that, but it doesn't always work correctly.

            My bad

              oobiekanoobie Yeah, a "lambda" is a function without a name. It has access to the local variables of its parent function, which is what you want... I think.

                  synthnostate Yep, that is pretty much what I want to do (integrating the timeout inside the main variable so work gets easier. Is there any good tutorial on it or do the docs explain it pretty well?

                      oobiekanoobie Your code still has some indentation problems.
                      If you want to make a typewriter effect on a label, here's how to do it by a single call from _ready() using a lambda signal callback:

                      extends Label

func _ready():
	type_it("Type this text into a typewriter")

func type_it(what: String, character_delay: float = .1):
	self.text = what 
	self.visible_characters = 0
	var t = Timer.new()
	add_child(t)
	t.wait_time = character_delay
	t.connect("timeout", func():
		self.visible_characters += 1
		if self.visible_characters == self.text.length():
			t.queue_free()
	)
	t.start()

                          xyz Ok thank you so much, that madew everything simpler! Have a nice day everyone who helped me 🙂

                            oobiekanoobie Is there any good tutorial on it or do the docs explain it pretty well?

                            The docs are decent. If you really want to learn all the tricks you can do with lambdas, learn some Javascript. They're usually called "closures" there btw. (Because they "enclose" the outer scope variables.)
