losing numbers when transfer to another scene ?

I don't know why. but it become a headache
where is the problem ? i need to keep all numbers save and not return to default (ZERO)

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using UnityEngine.UI;
4.  
5.  
6. public class ballpower : MonoBehaviour {
7.    
8.      public int levelsnumbers;
9.    
10.     // Use this for initialization
11.     void Start () {
12.            
13.         levelsnumbers = 0;
14.  
15.     }
16.    
17.     // Update is called once per frame
18.     void Update () {
19.         level1.enabled = false;
20.  
21.    }
22.  
23. void OnTriggerEnter (Collider other)
24.     {
25.          
26.         if (other.gameObject.CompareTag("eatj"))
27.         {
28.             other.gameObject.SetActive(false);
29.             levelsnumbers =  levelsnumbers+ 50;
30.             setcount();
31. }
32. }
33.  
34.  
35.     void savedataformap()
36.     {
37.         PlayerPrefs.SetInt("levelofmaps", levelsnumbers);
38.  
39.     }
40.  
41.     void loaddataformap()
42.     {
43.         levelsnumbers = PlayerPrefs.GetInt("levelofmaps");
44.     }
45.  
46. if (levelsnumbers >= 50)
47.         {
48.             level1.enabled = true;
49.            // level1.image.color = Color.green;
50.         }
51.  
52.     /////////
53. }
54.  
55.  

 

You're never calling loaddataformap in the code you've pasted.

The code you have pasted also won't compile, so I'm guessing something's missing?

If you want the data written to playerprefs to save between play sessions, you have to do a PlayerPrefs.Save() at one point.

 

what I'm missing ?
Baste, the save and load code it should run auto. So if I go to new scene and use the same code file that have all what i save it, have to be there ?

 

How does it auto run? I would like to know how this magic works. I know that PlayerPrefs.Save() is automatically called when you exit the game(not if it crashes or exits prematurely) and it loads PlayerPrefs at the start of the game, but you have to call the functions to get the data it has.

As @Baste pointed out savedataformap()/loaddataformap() are never called and Unity will never call them automatically you need to.

 

if only change the scene,you just need change the “levelsnumbers” to static
