Hello World!

Part of the Fundamentals section of Coddy's GDScript journey. Lesson 2 of 92.

The "Hello World!" program outputs the text Hello World! to the screen.

In GDScript, print() shows text on the screen. The text goes inside quotation marks:

print("Hello World!")

Every program in this course is written inside a block that starts with func _ready():. The lines inside it are indented by one level, and they run from top to bottom:

extends Node

func _ready():
	print("Hello World!")

For now, write your code on the indented lines. The Basic Program Structure lesson explains what the first lines mean.

Challenge

Beginner

Write a program that prints Hello World!.

Type it between the quotes in print(""), which is already inside the function.

Try it yourself

extends Node

func _ready():
	# Type your message between the quotes
	print("")

Test yourself
