The _ready method

Learn that _ready is called when the scene is ready.

What is _ready()?

_ready() is a lifecycle method called automatically by Godot when a node and all of its children have entered the scene tree and are fully ready. This method is triggered only once during the lifetime of the node.

extends Node2D

func _ready():
    print("Düğüm hazırlandı!")

Initial Setup

Initial setup tasks such as setting a node's initial position, health value, or accessing other child nodes are done inside _ready(). This is the first safe point where we can be certain child nodes exist.

extends Node2D

var can: int = 100

func _ready():
    position = Vector2(100, 200)
    print("Başlangıç canı: ", can)

Exercise Initial Value with _ready

Inside _ready(), define a variable named skor, set its value to 100, and print it to the screen with print(skor).

Show example solution

extends Node2D

func _ready():
    var skor = 100
    print(skor)

Test yourself

Which statement is true regarding the timing and frequency of the _ready() function?
- Called only when a physics step occurs
- Runs once when the node is deleted from screen
- Runs once when the node and its children enter the scene and become ready
- Runs continuously on every frame in the game
Show answer

Runs once when the node and its children enter the scene and become ready — _ready() runs once when the node and all its children are ready in the scene tree.

Define the _ready function

extends Node2D

func ____():
    print("Hazır")

Show answer

extends Node2D
