货币不保存硬币，我想加载分数

Question

大家好，我有分数和货币问题，游戏有硬币所以玩家可以收集它们所以我想要的，硬币添加到货币文本，每次我自动播放他们增加了我在游戏中获得的金币，最后加载并保存货币，所以当我重新打开游戏时，我可以看到收集的硬币没有改变

这是GameManager脚本

public Text scoreText, coinText, modifierText, hiscoreText;
private float score, coinScore, modifierScore;

    public void GetCoin()
{
    diamondAnim.SetTrigger("Collect");
    coinScore++;
    coinText.text = coinScore.ToString("0");
    score += COIN_SCORE_AMOUNT;
    scoreText.text = score.ToString("0");
}

这是shopPanel脚本

//test
public static int money = 0;
public Text coinsTxt;
public Text currencyTxt;
public static int totalMoney;

void Awake()
*{
         currencyTxt = PlayerPrefs.GetInt ("Coins");
}*
private void Update()
{
     coinsTxt.text = "Coins: " + currencyTxt;
    coinsTxt.text = "" + money;
}

void TotalMoney()
{
    money += totalMoney;
    currencyTxt.text = "" + totalMoney;
}

硬币脚本！

public class Coin : MonoBehaviour {

private Animator anim;

private void Awake()
{
    anim = GetComponent<Animator>();
}


private void OnEnable()
{
    anim.SetTrigger("Spawn");
}

private void OnTriggerEnter(Collider other)
{
    if (other.tag == "Player")
    {

        //CurrencyManager.gameManager.AddMoney(1);
        GameManager.Instance.GetCoin();
        anim.SetTrigger("Collected");
    }
}

}
