godot-4
i have trouble accessing variables from different scripts. the scene the script is in will be enabled in runtime so i cant really use signals and using a global variable would be a bad practice since i am planning on making a lot of such variables later on. i heard there was a way to use a function to sync data but i only found resources for GDscript. i am very confused, please help.
You have to be a little more specific as to what you’re trying to achieve.
There are plenty of ways to get a reference to a class instance at runtime:
PackedScene.Instantiate().GetNode().What do you mean by this; can you elaborate?
I need a better description of what your problem is in order to help you solve it.
Hi @sabadiasamidze45, for the multiple variables, you can easily use a built-in feature of Godot.
@Sweatix has already given nice options, but I would like to expand on the “singleton” one. In C#, for example, we can create a traditional singleton using the built-in Lazy <T>, but you can also create a singleton using Godot’s built-in AutoLoad feature, in this case you can set up a C# class or use a scene (that uses a C# class) to be your “central” place of variables.
Example from Docs:
public partial class PlayerVariables : Node
{
public static PlayerVariables Instance { get; private set; }
public int Health { get; set; }
public override void _Ready()
{
Instance = this;
}
}
Accessing/using the variable from C#:
PlayerVariables.Instance.Health -= 10;
To autoload a scene/C# class, go to Project > Project Settings > Globals > Autoload.

How many global variables? I’m not sure what the upper limit is but that’s what I use in my pixel art games.
@pdhales72 This question does not adhere to, or assist in the understanding of, the topic at hand. If you want help with your question, please create a new topic – preferably with a description that goes beyond the question of “how many global variables?”.
