from time to time i face the following problem:
Instancing a scene, add it as child and access it in _ready() or another "early" called function.
In the following example:
I instance a "Mainmenu" (CanvasLayer) - it has itself "Start" (Button) as child - and add "Mainmenu" as child to my Node2D to which the following Script snippet is attached to.
I want to instance Main_menu, add it as child and then connect to the "pressed" signal of the Start button. I do this essentially in the ready() function of Node2D.
onready var Main_menu = load("res://scenes/Main_Menu.tscn").instance()
onready var start_button = $Main_menu/Start
start_button.connect("pressed", self, "start_button_pressed")
The following error occurs:
error message: attempt to call function 'connect' in base 'null instance' on null instance. (referring to the line where start_button.connect is called)
I tried to fix this with yield(), deferred() and other functions since i expect that the Main_menu instance is not ready when i want to connect to its child "Start". Feel free to give advices and technical info since i am very new to Godot and would like to learn how it works.
Thanks for your help in advance.
