Very new to using Mono and C# so bear with me. I’m trying to port my current screen rescaling script to C# but I’m not having any luck. I can get the rest of the code to work, but I can’t get the right syntax for the onready function. Here’s the original code:

extends Node

onready var viewport = get_viewport()
onready var game_size = Vector2(
	ProjectSettings.get_setting("display/window/size/width"),
	ProjectSettings.get_setting("display/window/size/height"))

var game_res = Vector2(256, 240)

#Scale type for the game window.
#0: Integer Height - 10:9
#1: Integer Height - 4:3
var scale_type = 1

func _ready():
	viewport.connect("size_changed", self, "resize_viewport")
	resize_viewport()

func resize_viewport():
	var new_size = OS.get_screen_size()
	var scale_factor

	if new_size.x < game_size.x:
		scale_factor = new_size.x / game_size.x
		new_size = Vector2(game_size.x * scale_factor, game_size.y * scale_factor)
	
	if new_size.y < game_size.y:
		scale_factor = new_size.y / game_size.y
		new_size = Vector2(game_size.x * scale_factor, game_size.y * scale_factor)
	
	OS.set_window_size(new_size)
	OS.center_window()
	viewport.set_size_override(true, new_size)

The error I get is as follows in Visual Studio Code. Yes, I have the 3 needed extensions installed.:

The type or namespace name 'onready' could not be found (are you missing a using directive or an assembly reference?)

As of now there’s no such things as a onready equivalent for C#, but there’s a pull request on the project’s repo discussing about it: Add OnReady annotation to C# · Issue #2425 · godotengine/godot-proposals · GitHub
However, you can do the same thing by initializing the onready variables and set them in the _Ready() function:

Viewport viewport;
Vector 2 gameSize;
public void override _Ready()
{
 viewport = GetViewport();
 gameSize = new Vector2 (ProjectSettings.GetSetting("display/window/size/width"),ProjectSettings.GetSetting("display/window/size/height"));
//Rest of _Ready()
}
