What is the difference between these two class?

[HpVanDamme]

Are these fundamentally different stuff or they are the same type of thing? I am a bit confused. I know how to do classes in Python (which is more similar to second example) but seeing these two makes me confused bit.

(never mind the declaration names variables etc, I am asking about the structure and declaration stuff)

class_name Player

var health: int = 100
var name: String = "Unnamed"

func take_damage(amount: int):
    health -= amount
    if health <= 0:
        print("Player", name, "has died!")

class MyClass:
    func my_method():
        print("Hello, GDScript!")

The second is an “inner class”, you can’t define a top level class like that.

GDScript reference

Thanks I never knew about it.

Scripts in Godot always define classes, implicitly. The class keyword is for inner classes, which is basically a bunch of syntax for addressing and scope behaviour. You should usually create classes with scripts unless you have a reason to use an inner class. Other than that they behave identically.

Thanks for clarifying it. That makes total sense now.

Do I have to define the variables (message, variable) prior to the constructor ?

class_name My_Class

func _init(_m, _v):
	
       message = _m
       variable = _v

Also do we use “self” like in Python? I see some scripts use it and some do not and it is abit confusing Sorry to bother too much.

Yes, class variables need to be declared outside of any function.

self is optional, unless you’ve declared a local variable with the same name.

Thank you, super helpful.

One is an inner class and the other is a class
