Accessing variables

Unity Engine
1

I use a script called ObjectInfo on items in my game, is it possible to access a variable from those gameobjects without making it static?
I know you can use var Examplevar : ExampleScript;
but doesn’t that just make you attach a gameobject, not a script?

Hope this helps:

using System;
using UnityEngine;

class Script_A : MonoBehaviour
{
    public int hps = 10;

}

class Script_B : MonoBehaviour
{
    private Script_A data_script;

    void Start()
    {
        //If this script is on the same GameObject as Script_A:
        data_script = GetComponent<Script_A>();
        print("Script A has " + data_script.hps + " HPs left!");

        //The above is the same as saying:
        data_script = this.GetComponent<Script_A>();

        //if this script is NOT on the same GameObject as Script_A,
        //and there is only one instance of Script_A:
        data_script = (Script_A) FindObjectOfType(typeof(Script_A));
        print("Script A has " + data_script.hps + " HPs left!");

        //If you have many instances of Scrip_A (like you would if
        //it keeps track of HPs), you need to get a hold of the script
        //that belongs to the Gameobject you need info on. 
        //Use the first example by calling GetCompenonet on the object:
        data_script = SomeGameObject.GetComponent<Script_A>();
        print("Script A has " + data_script.hps + " HPs left!");
    }
}
