what's the result of PlayerPrefs.Get... if the key/value was never set?

Question

I'm wondering what the result is specifically if you try and get something from player prefs that was never set.

So like, if you did

 int x = PlayerPrefs.GetInt("ThingThatDoesntExist");

where "ThingThatDoesntExist" was never set anywhere in code

I can't find the player prefs data on my phone and thusly cant see if my variables are being created properly

Thanks for any help

ok, thanks, I see that obviously now after clicking the link : \

So I guess the default keys are int = 0, float = 0.0 and string = "" ? not sure where to find that info

Thanks again : )

Actually "defaultValue" is an optional parameter. Just look carefully at the signature of GetInt / GetString / ...

You usually want to pass your own defaultValue like this:

 int x = PlayerPrefs.GetInt("ThingThatDoesntExist", -1);
 if (x == -1)
 {
     Debug.Log("Not set yet");
 }

Alternatively you can check if the key exists with Has$$anonymous$$ey before you even try reading it.
