Player prefs not saving on game restart

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using UnityEngine.UI;
5. using UnityEngine.SceneManagement;

7. public class ShopControlScript : MonoBehaviour {

18.  
19.     // Use this for initialization
20.     void Start () {
21.         index = PlayerPrefs.GetInt("CharacterSelected");
22.         moneyAmount = PlayerPrefs.GetFloat ("MoneyAmount");
23.  
24.        isRifleSold = PlayerPrefs.GetFloat("IsRifleSold");
25.  
26.         if (PlayerPrefs.HasKey("IsRifleSold"))
27.         {
28.             if (isRifleSold == 1)

43.             riflee.SetActive(false);
44.         else
45.             riflee.SetActive(true);
46.  
47.  
48.         moneyAmountText.text = "Money: " + moneyAmount.ToString() + "$";
49.  
50.         isRifleSold = PlayerPrefs.GetFloat("IsRifleSold");
51.  
52.         if (moneyAmount >= 5 && isRifleSold == 0)
53.             buyButton.interactable = true;
54.         else
55.             buyButton.interactable = false;  
56.     }
57.  
58.     public void buyRifle()
59.     {
60.         moneyAmount -= 5;
61.         PlayerPrefs.SetFloat("IsRifleSold", 1);
62.         riflePrice.text = "UNLOCKED";
63.         buyButton.gameObject.SetActive (false);
64.         PlayerPrefs.Save();
65.     }
66.  
67.     public void exitShop()
68.     {
69.         PlayerPrefs.SetInt("CharacterSelected", index);
70.         PlayerPrefs.SetFloat("MoneyAmount", moneyAmount);
71.         PlayerPrefs.Save();
72.         SceneManager.LoadScene ("World1");
73.  
74.     }
75.  
76.     public void resetPlayerPrefs()
77.     {
78.         moneyAmount = 0;
79.         buyButton.gameObject.SetActive (true);
80.         riflePrice.text = "Price: 5$";
81.         PlayerPrefs.DeleteAll ();
82.     }
83.  
84.  
85.  
86. }
87.  

 

How do you know that it does not save? Perhaps some other script is calling resetPlayerPrefs()? Try disabling that first, and then read back Player prefs upon start

 

As pointed out, print out the values of your playerprefs. Also, look into a playerpref editor viewer on the asset store. There are free ones.

Now, that being said, don't use floats when you need an int. IsRifleSold is setup as a float, but using an int would be better since you're just using it as a bool tracker. You might set a float to == 0, but it may actually come out 0.00059 for example. So it may never actually equal 0.
