Trouble setting a bool value between two objects

Question

I am trying to make a quiz style sound match game, where a sound is played, and the player must choose between two balls which play similar sounds. One is of the same pitch and one is slightly different. I am trying to set a bool between the right answer(true) and wrong answer(false) but cannot understand the answers I have read about getComponent and using it to change the bool.

Here is my code for the ball1 (the script with the bool in it, and also the correct answer:

  using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ball1Click : MonoBehaviour {
     public bool isCorrect;
     public AudioSource beep;
     private ball2Click truthScript; 
 
     // Use this for initialization
     void Start () {
         isCorrect = false;
     }
     
     // Update is called once per frame
     void Update () {
 
     }
     void OnMouseDown(){
         beep.Play();
         isCorrect = true;
     }
 }

Here is the code for the other ball, the wrong answer that is supposed to get the component and change it to false if clicked on:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ball2Click : MonoBehaviour {
 
     public AudioSource beep;
     public ball1Click boolTruth;
 
 
     void Start () {
         //GameObject ball1 = GameObject.FindGameObjectWithTag (ball1);
         //boolTruth = ball1.GetComponent<ball1Click> ();
     }
 
 
     void Update () {
 
     }
     void OnMouseDown(){
         ballTruth.GetComponent (ball1Click).OnMouseDown (false); 
         beep.Play();
         boolTruth.isCorrect = false;
     }
 }

Hello @mgiga0420.

I haven't checked the logic of your code. But from what I see, you're trying to access the bool in an incorrect way. To access that bool from another script, your code should look like this:

Ball1Click:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 public class Ball1Click : MonoBehaviour
 {
     public static Ball1Click Instance {set; get;}

     public bool isCorrect;
     public AudioSource beep;

     void Awake()
     {
         Instance = this;
     }

     // Use this for initialization
     void Start()
     {
         isCorrect = false;
     }

     void OnMouseDown()
     {
         if (isCorrect == false)
         {
             beep.Play();
             isCorrect = true;
         }
     }
 }

Ball2Click:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 public class Ball2Click : MonoBehaviour {

   public AudioSource beep;

     void Start()
     {
         //GameObject ball1 = GameObject.FindGameObjectWithTag (ball1);
         //boolTruth = ball1.GetComponent<ball1Click> ();
     }

     void OnMouseDown()
     {
         if (Ball1Click.Instance.isCorrect == true)
         {
             beep.Play();
             Ball1Click.Instance.isCorrect = false;
         }
     }
 }

Also take note that the name of the class always starts with an upper case letter.
I removed the reference of the second script in the first one because I found no use for it. you can always add it back the same way I referenced the first script.

Keep in mind that I made a lot of assumptions to what you want, but you can always reply back and explain more so people could assist you furthermore.
