How to make Unity 3d gold system : <p>I have a problem. I am facing a problem when preparing the gold system in unity 3d. I am using PlayerPrefs and the system does not work.I am collecting gold, the value is increasing, but when I go out of the game and enter the game again, the gold value is 0 again. I want the gold value to remain the same at the next entrance when I am out of play. 
Can you help me please.</p>
