Question Cycle through array of letters

Hello I'm doing a padlock, where player need to press buttons and select correct letter.


Trying to do it with 'for' loop, but something doesn't quite gets for me. This is my code:

Code (CSharp):

1.     public char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();
2.     [SerializeField] private Text _letter01;
3.  
4.     public void UpArrow()
5.     {
6.         for (int i = 0; i < alpha.Length; i++)
7.         {
8.             _letter01.text = alpha[i].ToString();
9.         }
10.     }

Thanks!

 

Well currently you're looping through ALL letters, and setting them to the text.
So you'll always end up with "Z", since that's the last letter.
You should hold the index of the current letter.
Then in UpArrow(), add 1 to that index, and set the Text to the new letter.

Code (CSharp):

1.     public char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();
2.     [SerializeField] private Text _letter01;
3.  
4.     private int currIndex = 0;
5.     public void UpArrow()
6.     {
7.         currIndex++;
8.         if (currIndex >= alpha.Length)
9.             currIndex = 0; // Loop around
10.         // Set Text to new Letter
11.         _letter01.text = alpha[currIndex].ToString();
12.     }

 

Thank you!

 

After one picture, I can see that it will be an interesting game. Keep it up!
