question

Do you use Unity to develop your feature? And did you call both methods successfully? If your Give100Coins method call is successful, then you can check whether the virtual currency is reduced in Game Manager->Players->[Your Player]->VirtualCurrency, you can open Game Manager- >Title Overview->PlayStream Monitor page, and then run your program. Here you can see the detailed purchase process about who bought which item, and how much virtual currency has been reduced. If these are all successful, and your game UI still doesn’t be updates, maybe you just need to do it get the value of virtual currency again.

About SDK, we recommend that you keep the latest version.

If you have any errors during the running of the program, please provide us the detailed error messages.

The method "Give100Coins" is succesful and gives 100 coins, when pressing the button, and the virtual currency is being added. Under Game Manager->Players->[Your Player]->VirtualCurrency, I see that my Player has an amount of 28250 coins.

In Unity though, the amount of my virtual currency is not being shown.

Here is the script, that I use to make the amount of coins viewable:

public class VirtualCurrency : MonoBehaviour
{
    public Text HC_Text;
    public CustomAccountManagement CAM;
    private void Start()
    {
        HC_Text = GameObject.Find("HappyCoinsText").GetComponent<Text>(); 
        CAM = GameObject.Find("PlayFabManager").GetComponent<CustomAccountManagement>();
    }



    private void Update()
    {
        HC_Text.text = "Happy Coin(s): " + CAM.HappyCoins;
        //Debug.Log(CAM.HappyCoins);
    }



    public void Give100Coins()
    {
        PurchaseItemRequest purchaseRequest = new PurchaseItemRequest();
        purchaseRequest.CatalogVersion = "ShopItems";
        purchaseRequest.ItemId = "Coins";
        purchaseRequest.VirtualCurrency = "HC";
        purchaseRequest.Price = 50;
        PlayFabClientAPI.PurchaseItem(purchaseRequest, result => {
            Debug.Log("You recieved 100 Coins");
        }, error => {
            Debug.LogError(error.ErrorMessage);
        });
    }
}

The "CustomAccountManagement" is the script where the login/registration is being managed.

Here is the Login part of the script, again, with all the references:

public class CustomAccountManagement : MonoBehaviour
{
    public static CustomAccountManagement customAccountManagement;

    public LoginWithEmailAddressRequest loginWithEmail;

    //Virtual Currency
    public GetPlayerCombinedInfoRequestParams playerInfo;
    public int HappyCoins;



    //Login
    public void Login()
    {
        loginWithEmail = new LoginWithEmailAddressRequest { Email = userEmail, Password = userPassword };
        loginWithEmail.TitleId = PlayFabSettings.TitleId;
        //Virtual Currency
        loginWithEmail.InfoRequestParameters = playerInfo;
        // Request Login to PlayFab API
        PlayFabClientAPI.LoginWithEmailAddress(loginWithEmail, result => 
        {
            HappyCoins = result.InfoResultPayload.UserVirtualCurrency["HC"];
            OnLoginResult(result);
        }, OnPlayFabError);
    }
    public void OnLoginResult(LoginResult obj)
    {
        PlayerPrefs.SetString("EMAIL", userEmail);
        PlayerPrefs.SetString("PASSWORD", userPassword);
        PhotonNetwork.LoadLevel("Lobby");
    }
}
 

I activated these things in the GetPlayerCombinedInfoRequestParams:

Thank you! It worked. I just had to modify your solution a bit.

Here is the working solution, for the people who might want to know it:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using PlayFab.ClientModels;
using PlayFab;
using System;
using TMPro;


public class VirtualCurrency : MonoBehaviour
{


    public TMP_Text HCText;
    public CustomAccountManagement CAM;




    private void Start()
    {
        HCText = GameObject.Find("HappyCoinsText").GetComponent<TextMeshProUGUI>(); 
        CAM = GameObject.Find("PlayFabManager").GetComponent<CustomAccountManagement>();
    }




    public void Give100Coins()
    {
        PurchaseItemRequest purchaseRequest = new PurchaseItemRequest();
        purchaseRequest.CatalogVersion = "ShopItems";
        purchaseRequest.ItemId = "100Coins";
        purchaseRequest.VirtualCurrency = "HC";
        purchaseRequest.Price = 0;
        PlayFabClientAPI.PurchaseItem(purchaseRequest, result => {
            Debug.Log("You recieved 100 Coins");
            //Get Player Combined Info
            PlayFabClientAPI.GetPlayerCombinedInfo(new GetPlayerCombinedInfoRequest
            {
                InfoRequestParameters = new GetPlayerCombinedInfoRequestParams
                {
                    GetUserVirtualCurrency = true
                }
            },
            equals =>
            {
                string coinsOutput;


                coinsOutput = "Happy Coin(s)" + equals.InfoResultPayload.UserVirtualCurrency["HC"];


                HCText.text = coinsOutput;


                Debug.Log("Happy Coin(s)" + equals.InfoResultPayload.UserVirtualCurrency["HC"].ToString());
            },
            failure =>
            {
                Debug.LogError(failure.ErrorMessage);
            });
        }, error => {
            Debug.LogError(error.ErrorMessage);
        });
    }
}
