I use two-button to set the index value, once I click it gave value to the index.

public class tabbar : MonoBehaviour
{
   private int index = 0;
   public int buttonindex;
   public GameObject[] pannels;
   

   // Update is called once per frame
   void Update()
   {
       for (int i = 0; i < pannels.Length; i  )
       {
           if (i == index)
           {
               pannels[i].SetActive(true);
           }
           else
           {
               pannels[i].SetActive(false);
           }
       }
   }

   public void IWasClicked()
   {
       index = buttonindex;

   }

}

the first one is ok to set 0,but the second one no work?? any ideas?

CodePudding user response：

Try this and don't forget to update your buttonIndex:

public class tabbar : MonoBehaviour
{
   public int buttonIndex;
   public GameObject[] pannels;

   private void UpdatePannels(int index)
   {
       for (int i = 0; i < pannels.Length; i  )
       {
           pannels[i].SetActive(i == index);
       }
   }

   public void IWasClicked()
   {
       UpdatePannels(buttonIndex);
   }

}
