Does it matter where I put "extends" in GDScript?

Question

Reading tutorials for Godot I've seen both e.g.

extends StaticBody2D
class_name Foo

and

class_name Foo extends StaticBody2D

Are these equivalent? Is one preferred over the other? (And if so, why?)

Answer 1

Both lines are identical for newer versions of godot. There was a time around 2019, where extends needed to be before any class_name declaration, but they removed this.

So both examples lead to the same result: class_name registers a new Type "Foo" in the godot editor which extends StaticBody2D.

That being said, there is an official GDScript style guide. In the chapter Code Order they suggest to put class_name first and then in a serparate line extends

So if you want to follow the style guide, your code should look like this:

class_name Foo
extends StaticBody2D
