Hello, some one can help me how to put a var target scene in node 2d and area 2d in godot. Because only my area 2d asks me a target scene and if i put target scene is node 2d that just is apart.![enter image description here][1]

Here is a script of Area 2d
extends Area2D

export(String, FILE, “*.tscn, *.scn”) var target_scene

func _ready():
pass

func _input(event):
if Global.portal_first_quest == true:
if event.is_action_pressed(“ui_accept”):
if !target_scene: #is null
print(“no scene in this door”)
return
if get_overlapping_bodies().size() > 0:
next_level()
Global.portal_first_quest = false

if Global.unlocker_portal == true:
	if event.is_action_pressed("ui_accept"):
		if !target_scene: #is null
			print("no scene in this door")
			return
		if get_overlapping_bodies().size() > 0:
			next_level()
	if event.is_action_pressed("ui_accept"):
		if get_overlapping_bodies().size() > 0:
			print("Ohhh")
			return
if Global.unlocker_portal == false:
	if event.is_action_pressed("ui_accept"):
			if get_overlapping_bodies().size() > 0:
				print("A chave não foi ligada")
				return

func next_level():
var ERR = get_tree().change_scene(target_scene)
Global.unlocker_portal = false
Global.portal_first_quest = false

if ERR != OK:
	print("Something failed in door scene")

Global.portal_name = name
