Question by Lukicaa · Apr 07, 2021 at 09:35 PM · 2d game if-statements controls

Can somebody help me out? How can I refresh the script with right/left arrow?

I already tried while loop(probably i use it in the wrong way.)

 public class ReadableBook : MonoBehaviour
 {
     public Transform player;
     public Transform book;

     public GameObject PressE;
     public GameObject glowingBook;

     //public GameObject openedBook;

     public float minRange;
     public float maxRange;

     public GameObject[] pages;

     int broj = 0;
     int pressEmath = 0;
     // Start is called before the first frame update
     void Start()
     {
         glowingBook.SetActive(false);
         PressE.SetActive(false);
         //openedBook.SetActive(false);
         //pages.enabled = false;
         pages[0].SetActive(false);
         pages[1].SetActive(false);
         pages[2].SetActive(false);
     }

     // Update is called once per frame
     void Update()
     {

         if((Vector3.Distance(player.position, book.position) >= minRange) && (Vector3.Distance(player.position, book.position) <= maxRange))
         {
             if(Input.GetKeyDown(KeyCode.RightArrow))
             {
                 broj++;
                 Debug.Log(broj);
             }
             if(Input.GetKeyDown(KeyCode.LeftArrow) && broj > 0)
             {
                 broj--;
                 Debug.Log(broj);
             }
             glowingBook.SetActive(true);
             PressE.SetActive(true);
             if(Input.GetKeyDown(KeyCode.E))
             {
                 if((Vector3.Distance(player.position, book.position) >= minRange) && (Vector3.Distance(player.position, book.position) <= maxRange))
                 {
                     if(Input.GetKeyDown(KeyCode.RightArrow))
                     {
                         broj++;
                         Debug.Log(broj);
                     }
                     if(Input.GetKeyDown(KeyCode.LeftArrow) && broj > 0)
                     {
                         broj--;
                         Debug.Log(broj);
                     }

                         pages[2].SetActive(false);
                     }
                     else if(broj == 1)
                     {

I think that is better to create a separate method that enable a certain page when certain number is given, I made it to do a loop, so u can just increase or decrease brog in the Start() method without care about the limits here using a for loop with a if nested to identify the one to enable

   public void EnablePage(int brog){
         //create a loop from pages for any integer given
         int index = brog%pages.Length;

         //invert negative value
         if (index < 0)
               index = pages.Length + index;

         //print page to enable
         Debug.Log("stranica " + index.ToString());

         for (int i = 0; i < pages.Length; i++){
              if(index != i)
                 pages[i].SetActive(false);
              else
                 pages[i].SetActive(true);
         }
   }
