Question

I make a settings menu in my game. And I need to make it so that in the drop-down menu I can choose the type of control between the two options. Arrow control, and control on “WASD”. I started doing this using “match”, which reads the string value of the variable at the beginning of the code. And I need the settings script to be able to interact with the variable in the control script and change it. Please help!

You might want to consider using a global_script for this, then you can access it from everywhere.
When settings are selected you save it to the Global-scene called e.g. “Settings”

Settings.controls = # your controls here

Then you can access it from your other scripts:

my_controls = Settings.controls

There are different ways to do this. The easiest way would be to create a script with a class name that holds static functions and/or variables. Making an autoload class would be great way to organize that.

class_name Database extends Node

static var Name : String = "Adam"


class_name Actor extends Node

func ChangeName() -> void:
	Database.Name = "Michael"

You can also use get/set to basically share the same variables. You can also add additional functionality to make sure min/max are set.

class_name Settings extends Node

static var Volume : int = 100


class_name VolumeBar extends Node

var Current_Volume : int :
	get : return Database.Volume
	set(value) : Database.Volume = clamp(value, 0, 100)

Or you can even use arrays and dictionaries to manage data. Which makes saving the game easier, because data is stored in a convenient place.

class_name Database extends Node

static var Chest_List : Dictionary = { "Lv1_Chest1": false, "Lv1_Chest2": true }

class_name Chest extends Node

@export var Chest_ID : String

var Is_Chest_Open : bool :
	get : return Database.Chest_List[Chest_ID]
	set(value) : Database.Chest_List[Chest_ID] = value

func Pickup() -> void:
	if Is_Chest_Open == false:
		Is_Chest_Open = true
		# Perform Animation and Add items
		# Change State = Opened Chest
