Update and Get PlayerPrefs during runtime?
Hello there,
So I am working on my ingame store where a user can buy a powerup. Once he purchases it, an integer value gets increased by one which is then stored to a PlayerPref. However, during gameplay, the script checks the if the amount of that integer becomes equal to or less than 0, if it does, it's supposed to disable it. But, this doesn't happen until I reset the scene.
Basically, the GetInt doesn't update in realtime. It only updates once I reset the scene. My idea is to disable the powerup once its amount reaches to 0 which is stored in a PlayerPref. I hope I made it clear. Is there any way I can do that?
Here's a piece of code that might be helpful

Could you tell us which one of your three PlayerPrefs keys is the one which doesn't update? Which file/function/line does that call occur on? Which integer is being incremented?
Or actually, could you just print(PlayerPrefs.GetInt(...)); before and after you write to it so you can see for yourself if the value is updated or not. I am thinking the problem is not with PlayerPrefs but with your code. See this example, it works just fine...
using UnityEngine;
public class PlayerPrefsRealTime : $$anonymous$$onoBehaviour {
public int output;
void Update() {
PlayerPrefs.SetInt("Time", (int)Time.timeSinceLevelLoad);
output = PlayerPrefs.GetInt("Time");
}
}
