6.     public int myChar;
7.     private int price;
8.     public Text text;
9.     public Text priceText;
10.     void Start()
11.     {
12.         price = GetComponent<BuyScript2>().price;
13.     }
14.     void Update()
15.     {
16.         if (myChar == 1)
17.         {
18.             if (GlobalValues.character == 1)
19.             {
20.                 text.text = "selected";
21.                 priceText.text = "";
22.             }

60.                     priceText.text = "";
61.                 }
62.             }
63.             else
64.             {
65.                 text.text = "$" + price;
66.             }
67.         }

Using global variables come with a lot of overhead. The system you are using seems overly complicated and I would simplify your system. You could try something like this...

Code (CSharp):

1. using System;
2. using UnityEngine;
3.  
4. public class PlayerManager: MonoBehaviour
5. {
6.     // stores the locks for Player
7.     private string PlayerLocks { get; set; }
8.     private string PlayerPrice { get; set; }
9.     public static PlayerManager Instance { get; set; }
10.  
11.     // reset lock keys
12.     private void DefaultLocks()
13.     {
14.         // 1 = locked player
15.         // 0 = unlocked player
16.         // first one should be unlocked.
17.         PlayerLocks = "01111";               //EDIT ME
18.         PlayerPrice = "0,100,200,300,400";   //EDIT ME
19.         SavePlayerKeys();
20.     }
21.  
22.     public bool LockedPlayer(int playerId)
23.     {
24.         // if 0 value sent, return true
25.         if (playerId.Equals(0)) return true;
26.  
27.         int locked = Convert.ToInt32(PlayerLocks[playerId - 1].ToString());
28.  
29.         return Convert.ToBoolean(locked);
30.     }
31.  
32.     public float PricePlayer(int playerId)
33.     {
34.         float playerPrice = 0;
35.  
36.         // if 0 value sent, return true
37.         if (playerId.Equals(0)) return playerPrice;
38.  
39.         string[] splits = PlayerPrice.Split(',');
40.    
41.         float.TryParse(splits[playerId - 1], out playerPrice);
42.  
43.         return playerPrice;
44.     }
45.  
46.     public void UnLockPlayer(int playerId)
47.     {
48.         // if 0 value sent, return
49.         if (playerId.Equals(0)) return;
50.  
51.         // stores new locks.
52.         string tempKeys = "";
53.  
54.         for (int i = 0; i < PlayerLocks.Length; i++)
55.         {
56.             char c = PlayerLocks[i];
57.             if (i == playerId-1) c = '0';
58.  
59.             tempKeys += c;
60.         }
61.  
62.         PlayerLocks = tempKeys;
63.         SavePlayerKeys();
64.     }
65.  
66.     void Awake()
67.     {
68.         Instance = this;
69.         DontDestroyOnLoad(gameObject);
70.  
71.         if (!PlayerPrefs.HasKey("PlayerKeys"))
72.             DefaultLocks();
73.         else
74.             LoadPlayerKeys();
75.     }
76.  
77.     // save lock keys
78.     private void SavePlayerKeys()
79.     {
80.         PlayerPrefs.SetString("PlayerKeys", PlayerLocks);
81.         PlayerPrefs.SetString("PlayerPrice", PlayerPrice);
82.         PlayerPrefs.Save();
83.     }
84.  
85.     // load lock keys
86.     private void LoadPlayerKeys()
87.     {
88.         PlayerLocks = PlayerPrefs.GetString("PlayerKeys");
89.         PlayerPrice = PlayerPrefs.GetString("PlayerPrice");
90.     }
91. }

 

Here is a sample manager for the player manager.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class GameManager: MonoBehaviour
4. {
5.     public PlayerManager _playerManager;
6.  
7.     void Start()
8.     {
9.         _playerManager = PlayerManager.Instance;
10.     }
11. }

 

in my Buyscript :

by default character 1 is free and open to use. however at the moment if you start the game and go to the shop its ui text is showing select.
i would like it shows selected because it is free.
and then when user bought a new character , then character 1 ui text become select and new unlocked character ui text shows selected instead.
can someone say how to do that?
thanks for any help.
