How to access and change variables across nodes?

ionian

Basically, I have several buttons which need to control a single variable string. How can I go about creating a variable which can be accessed and changed by several different button nodes? i.e. I want the "blue" button to change the variable "color" to "blue" and the "red" button to change the variable "color" to red, and so on. Is there some sort of "global variable" or "scene" variable function that can call and set variables in GDscript? Thanks!

There are no global variables in GDScript, but you could use autoloads to achieve a similar goal.

@Calinou (or anyone who knows)

My project is an rpg which involves a lot of player data. I'm assuming the user ulpaded images should be be put/get in my backend db. But for the strings/numbers crunched during runtime it seems singletons are the way to go.

Do you know any good resources around singletons? I'm enjoying Godot but the official documentation is nauseating. And most of the stuff I Google is for 2.x, even though 3.1 is around the corner. Unfortunately, the official documentation is silent about what changes I should expect between versions. So learning about 2.x has gotten very frustrating bc I can't tell if I'm doing something wrong or if things just work different now. /rant

Anyways, singletons. Any good resources?
