question

Could you please clarify whether the UserDataSuccess function is the OnSuccess callback function of GetUserData method?

What you mean is to define a global variable GoldAmount, assign a value to it in the UserDataSuccess function, and assign its value to text in the loop, is it right? If so, firstly please make sure the variable GoldAmount has been assigned in the OnSuccess callback function of GetUserData method. Otherwise you cannot get the result of the API outside the callback function.

For clarification, the callback function of API request method pre-defined in PlayFab Unity SDK is designed to execute the code in order through nesting the function in the callback function. It will be difficult to execute functions in order if the callback functions weren’t defined correctly. Could you please clarify did your team defines a bool flag to represent the completion status of API request or could you please provide the code of the definition of UserDataSuccess function for our reference?

You can also add a delegated subscription to add callback function you need. This is my sample code.

    Action<GetUserDataResult> action;


    public void GetUserData(string id)
    {
        action = GetUserDataSuccess;
        action += GetUserDataSuccess2;
        PlayFabClientAPI.GetUserData(new GetUserDataRequest
        {
            Keys = new List<string>()
            {
                "GoldAmonut"
            },
            PlayFabId = id
        }, action, GetUserDataFail);


    }
