Set the username with an inputfield ?

Question

Hi guys, i'm new around unity/c#, and i'm trying to make an online leaderboard for a flappy bird like game,i followed Sebastian Lague's Dreamlo tutorial,and from the looks of it, i need a username,and can't quite figure it how to do it.I put an InputField in the main menu, but it doesn't save it at all. (No completions found for Player prefs) Any help would be awesome. Thanks! This is my wanna be code for that:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class InputName : MonoBehaviour {
 
     public string userName;
     public GameObject inputField;
 
     public void Awake()
     {
         userName = inputField.GetComponent<InputField> ().text;
 
     }
 }

Hi, first you need a public method that takes a string for parameter

 public class InputName : MonoBehaviour
 { 
      public string userName;
  
      public void SetUserName (string text)
      {
          userName = text;
      }
  }

Then, in the editor, add an action to the OnValueChanged event of the Inputfield to point to that method.

You can also save/reload it with PlayerPrefs, like :

 public class InputName : MonoBehaviour
  { 

   public string userName;
   public InputField inputField;

   public void Awake()
  {
      userName = PlayerPrefs.GetString ("playerName", "Player");
      inputField.text = userName;
  }
   public void SetUserName (string text)
   {
       userName = text;
       PlayerPrefs.SetString ("playerName", userName);
   }
   }

And for the sake of code awesomeness, I would use a property/accessor.

 public class InputName : MonoBehaviour
 {
     public InputField inputField;
     
     private string _userName
     public string userName
     {
         get
         {
             if (_userName == string.Empty)
                 _userName = PlayerPrefs.GetString ("playerName", "Player");
             return _userName;
         }
         set
         {
             _userName = value;
             PlayerPrefs.SetString ("playerName", _userName);
         }
     }
     
     public void Awake()
     {
         inputField.text = userName;
     }
     
     public void SetUserName (string text)
     {
         userName = text;
     }
 }
