How to access the particular instance of the Prefab ?

Questions & Answers
1

I have a prefab which is instantiated in the Scene and what i am trying to do is to disable with a (touch or timeCounter ) but sometime it disables all the instances of prefab and sometimes 2 or 3 of them.
i want to disable particular object which i have touched currently.

Here is my code:

void Update () {


		blastingTimeCounter -= Time.deltaTime;

		if (blastingTimeCounter <= 0) {
		
			DestroySquare ();
		
		}



		for (int i = 0; i < Input.touchCount; i++) {
		
			if (Input.GetTouch (i).phase == TouchPhase.Stationary) {
			
				hit = Physics2D.Raycast (Camera.main.ScreenToWorldPoint (Input.GetTouch (i).position), Vector2.zero);

				if (hit.collider != null) {
				
			                DestroySquare ();
    				
				}
					

			}

		
		}


	
}


void DestroySquare(){
		
	
		gameObject.SetActive (false);

		blastingTimeCounter = blastingTime;
	
	
}

Any Help will be Appreciated…

I think you meant to do this:

    protected void Update()
    {
        blastingTimeCounter -= Time.deltaTime;

        if (blastingTimeCounter <= 0)
        {
            DestroySquare();
        }
        
        for (int i = 0; i < Input.touchCount; i++)
        {
            if (Input.GetTouch(i).phase == TouchPhase.Stationary)
            {
                hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.GetTouch(i).position), Vector2.zero);

                if (hit.collider != null)
                {
                    //Destroy the gameobject of the collided square
                    DestroySquare(hit.collider.gameObject);
                }
            }
        }
    }

    protected void DestroySquare(GameObject colliderGameObject)
    {
        colliderGameObject.SetActive(false);
        blastingTimeCounter = blastingTime;
    }
