Requests, Response Data and Errors

All UnnyNet methods are asynchronous, the have a callback, which is invoke once the method is complete. The parameter of the callback is inherited from ResponseData.

public class ResponseData {
    public bool Success;
    public Error Error;
    public object Data;
}

public class Error {
    public int Code;
    public string Message;
}
ResponseExample = {
    success: true,
    error: {
        code: 1,
        message: 'unknown error'
    },
    data: //some data depending on the request
}

You need to check if Success is true to be sure that the request was successful and the Data is valid. Otherwise you need to read Error to understand what went wrong. Here is the list of error, which might occur:

public enum Errors {
    NotInitialized = -1,
    Unknown = 1,

    NoAccessToken = 1000,
    StorageRequestsMadeTooOften = 1001,
    NoSuchProduct = 1002,
    StorageError = 1003,

    UnityPurchasing_PurchasingUnavailable = 1010,
    UnityPurchasing_NoProductsAvailable = 1011,
    UnityPurchasing_AppNotKnown = 1012,
    UnityPurchasing_ProductIsNotAvailable = 1013,
    UnityPurchasing_PurchaseFailed = 1014,

    Nutaku_Error = 1100,
};

If everything is ok, you can read responseData.Data if needed.
