Save state between application launches (desktop)

Unity Engine

Can anyone tell me the simplest way to save state between application launches for a desktop application? By ‘state’ I mean a single number or high score.

PlayerPrefs is a good approach if it’s just a few values such as score.

An example:

            // actual construction of menu begins:
            if (!PlayerPrefs.HasKey("save" + i))               // no save file for group [n], new game button
            {
                selectedSlot.newGameButton.SetActive(true);
            }
            else                                               // save file found, label and display load button
            {
                selectedSlot.loadGameText.text = PlayerPrefs.GetString("save" + i);
                selectedSlot.loadGameButton.SetActive(true);
            }

I use this logic block to decide if a button is a new game button or a load game button, and if it is it names it.

To mess with it you literally just (elsewhere).

// add input field string to playerprefs save[slotIndex]
PlayerPrefs.SetString("save" + index, newGameName);

// delete the save file
PlayerPrefs.DeleteKey("save" + index);

So you’ll want to PlayerPrefs.SetInt(“score”, Score);

Isn’t Unity fun.
