How make lock/unlock playable characters in character selection screen?[Solved]

Using PlayerPref.HasKey is the best idea I got so far then disable the confirm button... How do I make unlockable characters if I press a key or something transitioning from different scenes?

Here is a character selection script I got from a tutorial. I added my own notes easy for you noobs to understand and I changed a few things.

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. using UnityEngine.SceneManagement;
4.  
5. public class CharacterSelection : MonoBehaviour
6. {
7.     private int selectionIndex = 0;
8.  
9.     private GameObject[] characterList;
10.  
11.     //[SerializeField]
12.     //private Button confirmButton;
13.  
14.     void Start()
15.     {
16.         //Get last character selected
17.         selectionIndex = PlayerPrefs.GetInt("CharacterSelected");
18.  
19.         if (PlayerPrefs.HasKey("UnlockedCharacterJake"))
20.         {
21.             //Unlocked a character named Jake
22.         }
23.  
24.  
25.         characterList = new GameObject[transform.childCount];
26.  
27.         //Get list of available characters
28.         for (int i = 0; i < transform.childCount; i++)
29.         {
30.             characterList[i] = transform.GetChild(i).gameObject;
31.         }
32.  
33.         //Hide unselected characters
34.         foreach (GameObject go in characterList)
35.         {
36.             go.SetActive(false);
37.         }
38.  
39.         //If no saved last character selected, set to default
40.         characterList[selectionIndex].SetActive(true);
41.  
42.     }
43.  
44.     public void ToggleLeft()
45.     {
46.         //Toggle off current character
47.         characterList[selectionIndex].SetActive(false);
48.  
49.         selectionIndex--;
50.  
51.         if (selectionIndex < 0)
52.         {
53.             selectionIndex = characterList.Length - 1;
54.         }
55.  
56.         //Toggle on new character
57.         characterList[selectionIndex].SetActive(true);
58.  
59.     }
60.  
61.     public void ToggleRight()
62.     {
63.         //Toggle off current character
64.         characterList[selectionIndex].SetActive(false);
65.  
66.         selectionIndex++;
67.  
68.         if (selectionIndex == characterList.Length)
69.         {
70.             selectionIndex = 0;
71.         }
72.  
73.         //Toggle on new character
74.         characterList[selectionIndex].SetActive(true);
75.     }
76.  
77.     public void ConfirmButton()
78.     {
79.         //Save character selected
80.         PlayerPrefs.SetInt("CharacterSelected", selectionIndex);
81.  
82.         //Play game
83.         SceneManager.LoadScene("Game");
84.     }
85. }
86.  

 

Nevermind, I think I answered my own question lol. I got it to work by using playpref.has key and disabling button.
