How to use a variable from one script in another?

Question

C++ / C#

For example, there are two scenes, Scene1 and Scene2
In Scene1 there is a Script1 script, which has a root variable, weighs on the rt object, and in Scene2 there is a Script2 script.
Can you please tell me how to use the root variable in Script2 script??

public class Test : MonoBehaviour
{
Script1 myscript;
void Start()
  {
    myscript = GameObject.Find("rt").GetComponent<Script1> ();
  }
}

This code does not work, apparently somewhere else you need to take into account the scene, please tell me how to solve this problem ??

Answer 1

If both scenes are not loaded at the current moment, then you cannot knock from one to the other.
It's like trying to find a bed in the kitchen. (kitchen, bedroom - different rooms/scenes)
You either make it a static class/variable, or a non-destructible object that will remain in the scene when a new one is loaded.
Or still load both scenes additively..so that you can search in both)
Using the analogy above, you would not build a kitchen or a bedroom. and the house from the kitchen and bedroom, and there they would already be looking for their bed in them)

Answer 2

In theory, the code should work if the root variable is public and there is an rt object on the stage that has a Script1 component.
