how to save cooins after reopen the app?

hi how can i save the coins when u close and open my app, and too have the same valuie on 2 scenes

 

Depends...how secure do you need your coins to be? You have playerprefs, text files, backend services, etc.

 

difference between playerpreft and text files? i dont need secure is my first project

 

Mostly where they are saved and how you access the data. I would say for your first project, you could do playerprefs fairly easy than. If all you want to do is save out coins.

 

yea i want to save the coins between 2 scenes andd when u reopen the app for a cooin shop, can u send me some link of help how to use??

 

i did this

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5.  
6. public class Playersave : MonoBehaviour
7. {
8.  
9.  
10.  
11.     void GetInt()
12.     {
13.         GameController.instance.Updateco();
14.         GameController.coin = PlayerPrefs.GetInt("score", GameController.coin);
15.         PlayerPrefs.Save();
16.     }
17.  
18.     // Update is called once per frame
19.     void Update()
20.     {
21.         GameController.instance.Updateco();
22.         PlayerPrefs.SetInt("Score", GameController.coin);
23.         PlayerPrefs.Save();
24.     }
25.     private void OnApplicationQuit()
26.     {
27.         {
28.             PlayerPrefs.SetInt("Score", GameController.coin);
29.             PlayerPrefs.Save();
30.         }
31.     }
32.     void Awake()
33.     {
34.         PlayerPrefs.GetInt("Score", GameController.coin);
35.  
36.     }
37. }
38.  
39. [CODE]
40. noot working xdd

 

If you don't need secure then PlayerPrefs is your easiest option. I'd recommend saving the coin value after every major coin spend and coin gain event (buying an item, after a level). This will reduce the pain for players if your app crashes for any reason.

 

yea anywya that code is not working xdd, so i add

Code (csharp):

1.  
2. [LIST=1]
3. [*]    GameController.instance.Updateco();
4. [*]        [URL='http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=PlayerPrefs']PlayerPrefs[/URL].[URL='http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=SetInt']SetInt[/URL]("Score", GameController.coin);
5. [*]        [URL='http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=PlayerPrefs']PlayerPrefs[/URL].[URL='http://unity3d.com/support/documentation/ScriptReference/30_search.html?q=Save']Save[/URL]();
6. [*][CODE]
7. [*]in the coins and when u go to menu ??
8. [/LIST]

 

You should generally not save playerprefs in an update like that. It does nothing for you and just keeps writing to the device over and over. Only save if they spend or earn coins.

Your GetInt calls are incorrect. Take a look at the PlayerPref docs for that. You need to assign it to an int value, not do it the way you have written.
