[Godot 3.0 beta 2] How to use $ in inner class?

Question

I have Node2D and label

Node2D

 - Label

My Example Script to Node2D

extends Node2D

func _ready():

    var state = Test.new(self)

    pass

class Test:

    var test

    func _init(test):

        self.test = test

test.$"Label".text = "Hello from Test Class"   # ERROR

    test.get_node("Label").text = "Hello from Test Class"
    pass

Answer 1

$ doesn't make sense in an inner class, because $ really is a shortcut for get_node(...), and get_node is a function inherited in Node. So you can't use $ unless your inner class is also a node, I wonder if that's possible though, never tested that.

However, using $ literally in place of get_node when calling it from a node variable... I don't think it's supposed to work. You could go ahead and just write test.get_node("Label").text instead. Maybe it could work if test is a node present in the tree though.

than you for your answer :)

Answer 2

There's no direct way as @Zylann already said but a way I do it is first declaring a variable myself with the Nodes info and then passing myself when creating an instance of the class

extends Node2D

var myself

class Test:

    var scene
    func _init(scn):

        self.scene = scn
        scn.get_node("Label").text = "Hello from Test Class"

func _ready():
    myself = get_tree().get_current_scene()
    t = Test.new(myself)
