Hi everyone,

i would like some explanation on how to call variables from different scenes and scripts into other. i've been trying to make a hit box dependant on stats changes,below is the code so far :

extends Area2D

var hit_direction = Vector2.ZERO
onready var stats_values = PLAYERSTATS
#variable acessed by all children nodes ( BOXES )
onready var damage = 1

func final_damage_value() :
    damage = damage * stats_values.strength

func _physics_process(delta):

That's a node (HITBOX) with a script of the same name, i'm trying to import variables from (PLAYERSTATS) in order to change "damage" variable wich is currently affecting the health of enemies.currently the damage set to 1 responds ok to the code, but i can't make formulaes.

I've tried the option "Autoload" in project settings but its not working so far,been struggling to understand how it works on Godot, even though i read the documentation

THANKS for any help or explanation!

Firstly forget about scenes and scripts those are terms used in the Editor portion of Godot.

During gameplay each node in the sceneTree is considered an instance and has a unique nodepath, instanceID and name

Each variable in the script attached to a node is called a member during runtime and can be accessed as well as functions from that node if referenced using one of the previously mentioned unique ways

Let's say you have this sceneTree

       ┠╴HITBOX(Area2D) [Hitbox Script]
       ┃  ┖╴Node2D
       ┖╴PLAYERSTATS (Area2D) [Player Stats Script]

Once you have the reference to the PLAYERSTATS node

onready var stats_values = get_parent().get_node("PLAYERSTATS")

you can access or change all of it's members directly by using that variable with .member_name


damage = stats_values.damage
