However, if you’re using Player Prefs to only store options settings, you might use Delete All to reset everything, returning all custom settings back to their default values. This will clear a specific key from Player Prefs file.Īlternatively, to delete all created keys, use the Delete All function.ĭelete All clears everything, so it should be used with caution, especially if you’re saving any kind of progress data using Player Prefs. Like this: PlayerPrefs.DeleteKey("myString")
To delete a key that you’ve created, simply call the Delete Key function of the Player Prefs class, passing in the key you want to remove. This means that, if you want to remove a preference key, you’ll need to manually delete it using a script, even when working in the editor. The Player Prefs values are stored locally on the device in a preferences file, meaning that they will exist after the game is closed. String loadedString = PlayerPrefs.GetString("myString") PlayerPrefs.SetString("myString", "Hello!") Like this: public void SetString(string value) PlayerPrefs.SetFloat("myFloat", 0.1234f) įloat loadedFloat = PlayerPrefs.GetFloat("myFloat") The Set Int function allows you to save and load an integer value however, similar methods are also available to store other data types, such as a float. Int loadedNumber = PlayerPrefs.GetInt(myNumber) To load the preference again, all you need to do is call Get Int, passing in the same key. This will create a new stored preference under that name or, if the key already exists, it will overwrite it, using the new value. It works by storing a string, float or integer value to disk with a key, which is a text string that’s used to store and recall a preference.įor example, to save an integer, simply call the Set Int function of the Player Prefs class and pass in the key you want to use to retrieve it again.
