Learn to instance a saved scene as a child node.
Instancing with instantiate()
Creating a new copy from a saved PackedScene resource is called scene instancing. In GDScript, this is done using the instantiate() method. For example, dozens of copies of a bullet or enemy resource can be spawned this way.
var sahne: PackedScene = preload("res://Dusman.tscn")
var yeni_dusman = sahne.instantiate()Adding to Tree with add_child()
An object created with instantiate() initially exists only in memory; it must be added to the scene tree to appear on screen. To place a node under another node, the add_child(yeni_dugum) function is used.
var yeni_obje = sahne.instantiate()
add_child(yeni_obje)
print("Düğüm ağaca eklendi")Practice Create and Add Node
Inside _ready(), create a new node with Node2D.new(), add it with add_child(), and print print("Örnek eklendi") to the screen.
Starter code
extends Node
func _ready():
# Yeni Node2D oluştur, add_child ile ekle ve mesaj yazdır
passSample solution
extends Node
func _ready():
var nesne = Node2D.new()
add_child(nesne)
print("Örnek eklendi")Expected output
Örnek eklendi
