[SOLVED]Starting To Write GDScript Code - Global Variables And Global Functions?

UnknownUser

Hi,

We are at a point where we can start writing GDScript code.

If we have a GDScript that is not attached to anything and it has variables and functions, can we access those variables and functions from any other GDScript in the entire game?

Let us know, thanks!

Below URL to one of our games on GitHub shows how we structure game projects: https://github.com/FallenAngelSoftware/AppGameKit2-SpaceSwap

With a few exceptions, a script's functions and variables cannot be accessed by other script's without it actually being used/instanced somewhere. What you'd normally do to have global variables and functions in your project is to create a Singleton. Go to the ProjectSettings and go to the AutoLoad tab to add a script as a Singleton in your project. Go consult the docs for more information. https://docs.godotengine.org/en/3.2/getting_started/step_by_step/singletons_autoload.html

@SIsilicon28 said: ... script's functions and variables cannot be accessed ... without it actually being used/instanced ... Indeed, when I made DyNo I created a DynamicNovel.gd script that wasn't attached to anything and used var DN = load("res://script/DynamicNovel.gd").new() to instance and gain access to its functions. Of course, that's not very efficient if you have multiple scenes so I used AutoLoad in the following game (Dinopia).

A singleton is one way. Or if what you need are a lot of functions in a bunch of files all over the place you can use static func.

Then you don't need an instance of the class just import the class. I have a few key global singletons, but a lot of my processing code I hide away in static functions.

Hopeful that the next release 4.0 has support for functions as "first-class" citizens. Not everything needs to be an instance of a class. Hope this helps.
