Playerprefs and collecting currency

Questions & Answers
1

Hello!

I’m having a problem with playerprefs.

I’m trying to add an in-game currency, and while I am able to “collect” the currency, I’m not able to update the amount of currency collected in real-time. It now only adds +1 to my currency when I reset the level (if I have collected >1 currency).

Here is my script. Thanks in advance!

public class CoinTrigger : MonoBehaviour
{
		public GameObject Coin;
		public int coins = 0;
		public Text coinAmount;

		// Use this for initialization
		void Start ()
		{
				coins = PlayerPrefs.GetInt ("Coins");
				
		}
	
		// Update is called once per frame
		void Update ()
		{
				transform.Rotate (0, 0, 50 * Time.deltaTime);
		}

		void OnTriggerEnter ()
		{
				if (Coin.gameObject.tag == "Coin") {
						PlayerPrefs.SetInt ("Coins", coins + 1);
						Destroy (Coin.gameObject);
						coins = PlayerPrefs.GetInt ("Coins");
				}
		}

		void OnGUI ()
		{
				coinAmount.text = coins.ToString ();
		}
			
}

Where are you saving?

PlayerPrefs.Save();

and you need to add 1 to the current value¨

coins += 1;
PlayerPrefs.SetInt ("Coins", coins);

or

coins = PlayerPrefs.GetInt ("Coins");
PlayerPrefs.SetInt("Coins", coins + 1);
