Summary - GDScript

Reinforce GDScript basics with a summary task.

Summary: GDScript Fundamentals

In this module, you mastered the fundamentals of GDScript, Godot Engine's native language. Scripts commence with extends Node, declare state with var, and organize routines via func.

extends Node

var score: int = 0

func add_score(amount: int) -> void:
    score += amount
    print("Score: " + str(score))

print() supplies console tracing, while : and -> establish type safety across scripts.

Exercise Print GDScript summary function

Define the function get_summary(name: String, level: int) -> String returning "Hero: " + name + " | Lv: " + str(level). In _ready, call it with "Warrior" and 10 and print the output.

Show example solution

extends Node

func get_summary(name: String, level: int) -> String:
    return "Hero: " + name + " | Lv: " + str(level)

func _ready():
    var result: String = get_summary("Warrior", 10)
    print(result)

Test yourself

Which statement regarding GDScript is correct?
- It uses Python-like indentation, inherits from Node classes via extends, and declares functions with func.
- It operates exclusively in web browsers and cannot be executed directly in Godot.
- Variables exclusively use const instead of var and custom functions cannot be written.
- Code blocks are delineated with braces { } and semicolons are strictly required.
