How to transfer a variable from script to another

Question

I have 3 sprites A, B and C, each one has area2d attached to it and collision shape

the script for A

extends Area2D
var done = 0

func _input_event(viewport, event, shape_idx):
    if event.type == InputEvent.MOUSE_BUTTON \
    and event.button_index == BUTTON_LEFT \
    and event.pressed:
        get_parent().hide()
        done = 1

And all like that

Now the main node has a script attached to it

extends Node2D

func _ready():
    if get_node("lA").get("done")==1 && get_node("B").get("done")==1 && get_node("C").get("done")==1:
            get_tree().change_scene("res://scenes/scene2.tscn")

But it doesn't work, why?

The error when doing if get_node("lA").done == 1 is

Invalid get index 'done' (on base: 'Sprite').

What I'm trying to do is collect some items, when done, move to a new scene

I push comment Button by mistake, but i want do an answer....

Answer 1

You should be able to access a variable like this:

get_node("SomeNode").variable

So in your instance:

if get_node("lA").done == 1

tried that, the scene stops working, at least in my question above, everything works except the script

I am not sure you can have more than the event parameter in processinput() but maybe if you could post your errors it would be easier to pon point your problem, and maybe some more explaining as your initial question is how to access a variable in another script.

Answer 2

You are trying to get a variable in the sprite, but the variable is in the area, because the script is in the area (2 nodes after main node). The correct path is get_node("1a/area2d") or whatever ... Sprite doesn't have "done" variable.
