@onready

Learn @onready in GDScript with a construct-specific explanation, a unique example, a practical boundary, and a mastery check.

10 min read • Beginner

@onready is an atomic GDScript topic inside Classes & Scripts. The example below uses the actual construct named by the lesson rather than a generic placeholder.

Focus on what @onready changes: the input, binding, control path, object state, collection, runtime effect, or language contract. Then alter one value and verify that the behavior changes for a reason specific to this feature.

Topic-specific example

gdscript-03-05-onready.gd
gdscript Try It Live 
@onready var label: Label = $Label
func _ready(): label.text = "Ready"
Edge case / engineering note

Change the key input in this GDScript example and predict the result first; the named construct should be the reason the behavior changes.
