Can you write the "scene change" code?

My projects working system is
There was a main scene. And its Just it. The ui scene is
Child scene in main. And in the main scene there is two nodes.
One is a (problem in a also) one is b.
İn a there is another Child scenes. And there is mobil buttons.
When you press is a button its hiding one and showing the another
One. B also working same. İts like lesson app. İn a lesson. İn b quiz.

extends Node

Global gd

var mevcut_sahne = null

func _ready():
   var sabit = get_tree().get_root()
   mevcut_sahne = sabit.get_child(sabit.get_child_count() - 1)
pass

func sahneye_git(yol):
call_deferred("yeni_sahne", yol)
pass


func yeni_sahne(yol):
  mevcut_sahne.free()
  var s = ResourceLoader.load(yol)
  mevcut_sahne = s.instance()
  get_tree().get_root().add_child(mevcut_sahne)
  get_tree().set_current_scene(mevcut_sahne)
pass

Changing the scene is like this, isn't it?

No it isnt.

func _on_giris_d_coraf():
    $giris/dersler.hide()
    $dersler/ders_coraf.show()
    $butom.play()
    $butomm.start()
func _on_ders_coraf_ddgeri():
    cders_sayfa = "0"
    $dersler/ders_coraf.hide()
    $giris/dersler.show()
    $butom.play()
    $butomm.start()


onready var cders_sayfa = "0"
func _on_dersler_coraf_icerik_tdgeri():
    var cdddd = get_node("dersler/ders_coraf"+cders_sayfa)
    if (cders_sayfa == "0"):
        cdddd = get_node("dersler/ders_coraf")
    cdddd.show()
    $dersler/dersler_coraf_icerik.hide()
    $butom.play()
    $butomm.start()

func _on_dersler_coraf_icerik_ders_acik():
    var cdddd = get_node("dersler/ders_coraf"+cders_sayfa)
    if (cders_sayfa == "0"):
        cdddd = get_node("dersler/ders_coraf")
    cdddd.hide()

Projenin oldukça karmaşık bir yapısı var ve herşey hatasız görünüyor.
PC'de herşey çalışıyor ama androidde...

---

look
Projesetting/Debug/Gdscript = buradan hataları kontrol et .

---

Hataları kontrol et derken?
Pc de hata vermiyor fakat android de kapanıyor.
Usb ile debuglamayı denedim fakat tam uygulama açılırken
Bağlantıyı kesiyor. Logcat de aynı şekilde

---

Tüm seçenekleri işaretledim fakat kayda değer birşey bulamadım.

---

androidde nereye takıldığını debuglamamın bir yolu var mı?
godotla veya godot dışında

---

Bununla ilgili bilgim yok . Türkçe karakter kullanmış olabilir misin . kontrol et .
"Dosyları ara" kısmına Türkçe karakterlere tek tek bak bi.

---

Tamam deneyeceğim
