Chapter 1a - First script

Your first GDScript

Every sandbox script starts the same way: extend SceneTree, put code in _init(), then quit().

extends SceneTree

func _init():
    print("Hello Godot")
    quit()

Quiz

Entry point

1 / 2

Why must sandbox scripts call quit()?

Pick an answer to see if you are right.

Printing

print writes to the output. Strings use double quotes. You can print several values in one call.

print("score", 12)
print("a", "b", "c")

🧪 Try it

Challenge: print a product

Complete _init so it prints the result of 6 * 7 (one number), then quits.

Indentation

Indent with 4 spaces (Tab in the editor inserts spaces). Click Reset if an old draft has broken indent.

Comments

# starts a comment to the end of the line.

# This is a comment
print("still runs")  # trailing comment

Exercises

Three steps: print two lines, print a labeled score, then build a line from two variables.

Activity: Two lines

Print Hi on the first line and Ada on the second line.

Hi
Ada
