extends and variables

Learn to derive a class with extends Node and define variables.

The extends keyword

In GDScript, a script file typically begins with the extends statement. This keyword designates which Godot class the script inherits from.

extends Node
# This script now inherits all capabilities of a Node object

For instance, writing extends CharacterBody2D for a 2D character inherits built-in movement functions from that class.

In GDScript, variables are declared using the var keyword. A variable can be directly assigned an initial value and modified throughout gameplay.

extends Node

var health = 100
var player_name = "Archer"
var is_alive = true

Variables store runtime data such as character health, ammo counts, or inventory items in memory.

Assign "Hero" to name and "Knight" to role. Print Player: Hero | Role: Knight to the console.

Show example solution

extends Node

func _ready():
    var name = "Hero"
    var role = "Knight"
    print("Player: " + name + " | Role: " + role)
