How to access a variable from another script which has been edited in Ready()?

godotMonoNoob

If I have:

public class FirstScript : Node2D
{
    public int testInt = 1;

    // Called when the node enters the scene tree for the first time.
    public override void _Ready()
    {
        testInt = 5;
    }
}

And:

public class SecondScript : Node2D
{
    public override void _Ready()
    {
        FirstScript first = new FirstScript();
        GD.Print(first.testInt);
        //This prints 1, when I want it to print 5
    }
}

How do I get it so in second script, it will print 5 instead of 1?
How do I access the firstscript variable in the secondscript in a way that it will retain the changes that I made in the Ready function of firstscript?
Am I not supposed to use FirstScript first = new FirstScript() and instead use GetNode? If so, how?

Thanks

I haven't used C# with Godot, so this may or may not be helpful.

But with GDScript, _ready() is not called until the node is added to the scene tree, typically by using add_child().

There's also a Node method request_ready() that queues _ready() to be called again. I don't know if that has any effect on a node that's not in the scene tree.

There's also a method _init() that's called when a node is created, before it's added to the scene tree.

Complementing @DaveTheCoder answer, your main issue is that you're creating a node, but never adding it to the main tree, so that node ready will never be called.

To solve it, add your node "first" (add_child). See https://kidscancode.org/godot_recipes/3.x/basics/tree_ready_order/

Note also that game objects are usually in scenes so more often it’s the case you’ll be preloading a scene and adding it to another scene (instead of .new() a script), after which the ready function will be called when it’s ready in the scene. The _init constructor.
If you’re script is not going to be attached to a game node use _init like a regular constructor.

Ah I figured it out, you do use Node.Get() if you want to access a variable edited in the ready instead of making an instance of the class, however the ready functions are processed in a certain order in godot. It processes the children of a parent top down and then the parent,

eg if

ParentNode
        Child1
        Child2
        Child3

It would do, Child1 ready() --> child2 ready() --> child3 ready --> ParentNode ready().

Thats why it wasn't working, because my nodes were in the wrong order, and I was making an instance of the class instead of using var thing = (cast to myVariable type)Node.Get("myVariable");
