I want to parse array commands in GDScript using pattern matching (match). Commands look like ["attack", target_node, 50]. Write a match structure matching a 3-element array starting with "attack" that extracts the second and third elements into local variables target and damage, along with a catch-all branch for unmatched commands.
| Checked | Without skill | With skill |
|---|---|---|
| The array match pattern uses the var keyword before variable names to bind elements. | Missed | Passed |
| The match block includes a default branch using the wildcard _:. | Passed | Passed |

Note: This skill is GDScript-specific by design. For C# patterns, see csharp-godot and csharp-signals.
Always add type hints — they catch bugs at parse time, improve autocomplete, and boost performance.
# Variables
var health: int = 100
var speed: float = 200.0
var player_name: String = "Hero"
var direction: Vector2 = Vector2.ZERO
# Constants
const MAX_HEALTH: int = 100
const GRAVITY: float = 980.0
# Functions — parameters and return type
func take_damage(amount: int) -> void:
health -= amount
func get_direction() -> Vector2:
return Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
# Inferred typing with :=
var pos := Vector2(100, 200) # inferred as Vector2
var items := [] # inferred as Array (untyped)
var count := 0 # inferred as int
