First and foremost, thank you for reading this question. I have already viewed the "Accessing variables across scripts" Official YOUTUBE Video many many times. I have also read many questions and answers on this forum hoping to glean some information that may help. Still having problems, you all are my last hope.

I think I may not be understanding some of the relationships involved between classes.

HERE are SCREENSHOTS of my Editor/Inspector proving that my PREFABS should be linked properly:

LOGIC:

1. Fist I set GameController as static. I understand this allows it to have global variables that other classes can access and modify.

2. Then, I generate 6 different spheres with different colors.

3. Then, the game increases the Z position for each cloned sphere, until >4, then it switches the direction so the spheres are supposed to come back. (Z position declination)

4. And while the Spheres, do correctly Instantiate() on the screen, and move forward on the Z axis.....

THE PROBLEM:

1. is that the spheres continue on the +Z axis forever. They never switch and come back

2. In GameController script, the print function for refscript.tempVector always prints "0,0,0"

3. It's as if Gamecontroller never received the appropriate value.

GameController.cs

sing UnityEngine; using System.Collections;

 public class GameController : MonoBehaviour {
 
 
     public static GameController controller; // Allows this script to store the base values and this is now the holder if such values.
 
     //Loading Script use
     public Material greenMaterial;
     public Material blueMaterial;
     public Material whiteMaterial;
     public Material redMaterial;
     public Material pinkMaterial;
     public Material yellowMaterial;
     public float speedInterval;
 
     // For referencing the vales on ObjectBehavior.cs
     public GameObject objectContainingScript;                        // PUBLICVAR (its a GameObject) (insert in the editor which object contains the script)
     
 
     // GENERAL DEFINITIONS (HIDDEN IN INSPECTOR)
     [HideInInspector]public Objectbehavior scriptref;                // PUBLICVAR (The Class ObjectBehavior) (set it as scriptref)
     [HideInInspector]public Material materialToUse;
     private GameObject sphere;
     private float myX;
     private Vector3 tempVector;
 
 
 
 
 
     void Awake (){
         if (controller == null)
         {
             DontDestroyOnLoad (gameObject);
             controller = this;
         }
         else if (controller != this) 
         {
             Destroy(gameObject);        
         }
 
     }

         sphere = objectContainingScript;                                        // its the same object so we can use it.
 
             scriptref = objectContainingScript.GetComponent<Objectbehavior> ();
         int ballType = 1;                                                        // greenMaterial by default
         for (myX = 0; myX < 6; myX++) 
         {
             tempVector[0] = myX*2;
             tempVector[1] = 0;
             tempVector[2] = 0;
             ballType = (int)Random.Range (1f,7f);
             if (ballType == 1){materialToUse = greenMaterial;}
             if (ballType == 2){materialToUse = redMaterial;}
             if (ballType == 3){materialToUse = yellowMaterial;}

             if (ballType == 5){materialToUse = pinkMaterial;}
             if (ballType == 6){materialToUse = whiteMaterial;}
             sphere.renderer.material = materialToUse;                            // set the clone sphere's color to the color necessary
             Instantiate (sphere, tempVector, transform.rotation );
         }
     }
     
     // Update is called once per frame
     void Update () {
         values inside of the object's script <ObjectBehavior>
         print (scriptref.mytempVector);                                            //scriptref.tempVector always = 0,0,0 @ RUNTIME , YET THE BALL MOVES FORWARD
         if (scriptref.mytempVector[2] > 4) {scriptref.direction = -1;}            // I am trying to check that balls Z position, and if exceeeds parameter then switch it's direction
         if (scriptref.mytempVector[2] < 0) {scriptref.direction = 1;}            // ****** it autocompletes the variable like there is a connection, but then it keeps returning 0,0,0
                                                                                 // The editor Scene view proves the balls move outward in a positive Z direction
