Is there a way to call a function that is inside a script not connected to a node?

I have a solitary script full of functions that I want to call, but I do not know how to do it.

What do you mean by “Solitary script”? How does your project look like? It is not on a node? Does it contain just static functions?

The script is not tied to any node, so I called it solitary. No, it has no static functions.

I you can do it with preload and load. For example, your script is

func _init():
    #do constructor stuff if needed
func hello():

And then you instantiate it from a node:

extends Node2D
func _ready():
    var script = preload("res://").new()

Do i explain myself?

It doesn’t have to be a class. Any script can be loaded and used (so you don’t need the _ready function in your or any sort of extends), you can have libraries of “static” functions.

In order to use the way you described, you would need functions inside it to be declared as static.
Otherwise, you have to make an instance of it, like so:

var script = preload("res://")
var instance =

The reason is, scripts are both classes and resources. It means that when you do load or preload on a script file, what you get is the class itself. Then you can use that class to either call static functions, or make instances of it.

Note: if you make instances with new(), indeed there is no reason to implement _ready() because that function is only called on scripts extending Node classes, after they enter the tree.
On the other hand, if your script is a plain class that doesn’t extend anything, you can implement _init(), which acts as a constructor.

Interesting, it seems to work just fine without static so long as you don’t access any members, though the terminal does give a warning “Can’t call non-static function”.

yes, It works just as i answered, cause i tried before posting answer. However, if it’s not best practice of if it wont always work, i must edit answer. Did not have to create instance either to run hello. Is that not expected?

if i do an instance like

var instance =

shouldn’t i then run


instead of

Yes, my bad, I corrected it
