Working with multiple gameobjects

Question

I have the requirement to Hide and Show the specific gameobjects on specific button click.

Button-1:-

  gameobject[0].SetActive(false);
  gameobject[1].SetActive(false);
  gameobject[2].SetActive(false);
  gameobject[3].SetActive(true);
  gameobject[4].SetActive(false);
  gameobject[5].SetActive(false);
  gameobject[6].SetActive(false);
  gameobject[7].SetActive(true);
  gameobject[8].SetActive(true); 

Button-2:-

  gameobject[0].SetActive(true);
  gameobject[1].SetActive(false);
  gameobject[2].SetActive(false);
  gameobject[3].SetActive(false);
  gameobject[4].SetActive(false);
  gameobject[5].SetActive(false);
  gameobject[6].SetActive(false);
  gameobject[7].SetActive(true);
  gameobject[8].SetActive(false); 

Like these, I have some 10 buttons. It seems code is so lengthy and not efficient. Is there any way to optimize this?

Thanks.

Answer 1

You can assign the "indexes to activate" to an array in a button click handler, then call a method that loops over the game objects and sets their state according to whether the passed parameter contains their index:

private void Button1_Click()
{
    var toActivate = new[] { 3, 7, 8 };
    ActivateGameObjects(toActivate);
}

private void Button2_Click()
{
    var toActivate = new[] { 0, 7 };
    ActivateGameObjects(toActivate);
}

private void ActivateGameObjects(int[] toActivate)
{
    for (int i = 0; i < gameobjects.Length; i++)
    {
        gameobjects[i].SetActive(toActivate.Contains(i));
    }
}
