Accessing variable in a specific instance of a prefab

Question

I have a script on Object_A called script_A. It instantiates instances of prefab Object_B which has script on it called script_B. This script contains an public integer variable called randomNumber.

Let’s say I’ve created 3 instances of Object_B and each instance’s randomNumber is unique.

How to I retrieve each specific instance’s unique randomNumber in script_A?

Here's script_A:

 public Rigidbody Object_B;
 public int randomNumber1;
 public int randomNumber2;
 public int randomNumber3;

 void Update ()
 {
     if (Input.GetButtonDown ("Fire1")) 
     //on left click, instantiate an instance of Object_B at Object_A's location+rotation
     {
         Rigidbody Object_B_Instance;
         Object_B_Instance = Instantiate (Object_B, transform.position, transform.rotation) as Rigidbody;
     }
     randomNumber1 = GameObject.Find("Object_B (clone)").GetComponent<script_B>().randomNumber;
     randomNumber2 = GameObject.Find("Object_B (clone)").GetComponent<script_B>().randomNumber;
     randomNumber3 = GameObject.Find("Object_B (clone)").GetComponent<script_B>().randomNumber;
 }

Here's script_B

 public int randomNumber;

 void Start ()
 {
     randomNumber = Random.Range (1, 10);
 }

Hello @GeorgeLuther,

Please check this solution

In Script_A script take one list of Script_B Component and when you instantiate B object add it to the list and access it wherever you want.

 public class Script_A : MonoBehaviour
 {
 
     public GameObject prefab;
     public List<Script_B> generatedObjects = new List<Script_B> ();
     // Use this for initialization
     void Start ()
     {
         
     }
     
     // Update is called once per frame
     void Update ()
     {
         if (Input.GetKeyDown (KeyCode.Space)) {
             for (int i = 0; i < 3; i++) {
                 GameObject go = Instantiate (prefab, transform.position, transform.rotation)as GameObject;
                 Script_B secondObject = go.GetComponent<Script_B> ();
                 generatedObjects.Add (secondObject);
             }
         }
 
         if (Input.GetKeyDown (KeyCode.A)) {
             for (int i = 0; i < generatedObjects.Count; i++) {
                 Debug.Log (generatedObjects [i].randomNumber);
             }
         }
     }
 }

and

 public class Script_B : MonoBehaviour
 {
 
     public int randomNumber;
 
     // Use this for initialization
     void Start ()
     {
         randomNumber = Random.Range (1, 10);
     }
     
     // Update is called once per frame
     void Update ()
     {
         
     }
 }

Hope you are looking for this
