Destroy One Child, Not All

I have three Scripts

Script One

Game Manager: SIMPLY(Guitar Hero Like Game)

4 Tubes, 4 Spawnners and 4 receivers Each tube has an Inactive atom parent over the Spawnners which has a variable spawnner and receiver each assigned according to their position. So Parent 1 is assigned receiver 1 and spawnner 1 through inspector, atom parent 2 is assigned receiver 2 spanner 2 etc.

So...

Script 1 Game Manager (Outside of everything, randomly picks a spawnner and instantiates the atom parents( all 4 atom parents spawnners and receivers are in a list)

GameObject atom1_child = Instantiate(atomReference[0], atomSpawnners[0].transform.position, atomSpawnners[0].transform.rotation) as GameObject;

---

Script Two

attached to the child gameObject(atoms) when it spawns... and collides, in my case gets within distance with the base or what I call the receiver...

buttonOccupied = true; // Has a boolean to make sure atom is inside receiever receiver.GetComponent().SA_Atom = gameObject; //Script 3 in receiver //Script 3 is a controller with the variable SA_Atom

So when this object is at a certain distance from base or ITS receiver, it self assigns itself to script 3.

---

Script 3 When I ray cast to a specific receiver

if (hit.collider.gameObject && SA_Atom.GetComponent().buttonOccupied == true) //If I hit the receiever...

{

Destroy(SA_Atom);

}

---

Heres the issue, ALL atom childs are being destroyed not just one. I tried several solutions, I cant wrap my head around it

ALSO, it doesnt destroy all atomChilds when the boolean is false, but when boolean is true and I click the receiver, it destroys all. I need it to be that ONE Specific Self assigned atom

HERES THE CODE

//Script ONE outside of anything

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

public class script_GameManager : MonoBehaviour

{

     public GameObject[] atomReference = new GameObject[4];
 private float spawnTimer;
 public float setTimer;
 public GameObject[] atomSpawnners = new GameObject[4];
 private int randomSpawnnner;

 void Start()
 {
     spawnTimer = setTimer;
 }
 
 void Update () 
 {
     timerUpdate();
 }

 
 void timerUpdate()
 {
     spawnTimer -= Time.deltaTime;
     if(spawnTimer <= 0)
     {
         spawnTimer = setTimer;
         randomSpawnnner = Random.Range(0, 4);
         atomSpawn();
     }
 }

 void atomSpawn()
 {
     switch (randomSpawnnner)
     {
     case 0:

         GameObject atom1_child = Instantiate(atomReference[0], atomSpawnners[0].transform.position, atomSpawnners[0].transform.rotation) as GameObject;
         atom1_child.SetActive (true);

     break;

     case 1:

         GameObject atom2_child = Instantiate(atomReference[1], atomSpawnners[1].transform.position, atomSpawnners[1].transform.rotation) as GameObject;
         atom2_child.SetActive (true);

     break;
     
     case 2:

         GameObject atom3_child = Instantiate(atomReference[2], atomSpawnners[2].transform.position, atomSpawnners[2].transform.rotation) as GameObject;
         atom3_child.SetActive (true);

     break;
     
     case 3:

         GameObject atom4_child = Instantiate(atomReference[3], atomSpawnners[3].transform.position, atomSpawnners[3].transform.rotation) as GameObject;
         atom4_child.SetActive (true);

     break;
     
     }

 }

}

//Script 2 inside parents or atoms

using UnityEngine; using System.Collections;

         targetReceiver = receiver.transform;
         //easy reference to the vector 3 conversion of the receiver

         receiverDistance = Vector3.Distance(transform.position, targetReceiver.transform.position);
         //converts the vector 3 (x,y,z) distance into a float

         if(receiverDistance > 0.1)
         {
             atomMove();
             //atom will move if far from the zero, otherwise, stop
         }//EO IF
         if (receiverDistance <= 0.1 && receiverDistance >= -0.1)
          
         {
             buttonOccupied = true;
             //button is inside receiver
             this.receiver.GetComponent<script_buttonController>().SA_Atom = gameObject;

             buttonParticle.SetActive(true);
             //if atom is close to zero, activate particle system, other wise will be shut off by controller
             //a new spawning atom may overrde it being true to false even if the "zero" is occupied
         }


 }
 

 void atomMove()
 {
     transform.Translate(Vector3.down * atomSpeed * Time.deltaTime);
 }

 public void atomSend()
 {
 
     //Destroy(gameObject);

 }
