How to implement data reset in PlayerPrefs?

Question

Unity

I need to reset the PlayerPrefs when the application closes, but how can I track any closings? through close everything, if you just exited through the button or brushed off the application, application crashes. Which team can track everything completely?

Answer 1

Application.Quit- there is nothing else. Well, then you can delete it when you open it.

Answer 2

What an awesome example of an XYZ error. You don't need all of this at all - simply because it's a bad use of PlayerPrefs. Prefs are needed just to store information BETWEEN launches. Those. they just need to be SAVE at the exit \ minimize \ save points, and at the start of the game - LOAD. This is the save game.
And within the framework of a running game, it is enough to keep everything in memory

Answer 3

PlayerPrefs is designed to do the opposite, keep the data, not reset it.
If you need to reset on deactivation/exit, you can do the same at startup.

void Start()
{
    Application.quitting += () => { OnClear(false); };
    Application.focusChanged += OnClear;
}

void OnClear(bool b=false)
{
    PlayerPrefs.DeleteAll();
}
