Introduction

Virtual items are game items, that can be purchased using game currency or can be rewarded as completing an Achievements. The Virtual item can also be minted an turn into NFT through the PLAY Dev Dashboard.

For example, a virtual item can be:

• Racing Game: It can be different types of cars.

• Puzzle game: It can be a bunch of hints pack.

• Match-3 game: There can be different types of power-ups.

• Shooting Game: Different types of guns, ammo etc

Virtual Items can be created using the PLAY Dev Dashboard.

VirtualItem

• id (string): Unique id for the virtual item.

• name (string): Name of the virtual item.

• description (string): Description of the virtual item.

• appIds (List<string>): List of project id where your item can be accessed.

• createdAt (long): Date and time of the item creation.

• updatedAt (long): Date and time of the last update on the item.

• createdBy (string): User ID of the creator of the item

• updatedBy (string): User ID of the last person who updated the item.

• isStackable (bool): Indicate if the item can be stored under the same ID in the inventory.

• tags (List<string>): List of tags to filter the items.

• properties (List<Property>): List of properties you can store in json format to retrieve with the virtual item.

• prices (List<PriceInfo>): List of prices defined for this item. Used to process transaction with the user's currencies.

Virtual item class methods

• IsNFT();

  • Return a bool to let you know if the virtual item is an NFT or not.

• GetRGNCoinPrice();

  • Return the price in rgn-coin if the item is an NFT.

• GetCustomCoinPrice(string currencyName);

  • Return the price based on your custom currency setup in the virtual item.

Get All Virtual Items for current app

using System.Collections.Generic;
using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    public async void GetAllVirtualItem()
    {
        List<VirtualItem> virtualItems = await VirtualItemsModule.I.GetVirtualItemsAsync();
        foreach (var virtualItem in virtualItems)
        {
            Debug.Log($"Virtual item id : {virtualItem.id} \n" +
                $"virtual item name : {virtualItem.name}");
            // etc
        }
    }
}

Get with pagination

There is also a method overload for pagination requests. The pagination means you request not all items at once for the project. In this example every request contains 5 items. Each time you call the method, 5 more items will be loaded and added to the loaded item list.

using System.Collections.Generic;
using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    private List<VirtualItem> allLoadedItems = new List<VirtualItem>();
    private VirtualItem lastLoadedItem = null;

    public async void GetVirtualItemsPaginationAsync()
    {
        List<VirtualItem> virtualItems = new List<VirtualItem>();
        if (allLoadedItems.Count > 0)
        {
            lastLoadedItem = allLoadedItems[allLoadedItems.Count - 1];
            virtualItems = await VirtualItemsModule.I.GetVirtualItemsAsync(5, lastLoadedItem.id); // Get 5 more items
        }
        else
        {
            virtualItems = await VirtualItemsModule.I.GetVirtualItemsAsync(5, ""); // Get 5 first items
        }
        allLoadedItems.AddRange(virtualItems);
        Debug.Log(allLoadedItems.Count);
    }
}

Different ways to retrieve virtual items :

Get by tags

using System.Collections.Generic;
using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    public async void GetVirtualItemsAsync()
    {
        List<string> tags = new List<string> { "guns", "rifles" };
        List<VirtualItem> virtualItems = await VirtualItemsModule.I.GetByTagsAsync(tags);
    }
}

Get by ids

using System.Collections.Generic;
using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    public async void GetByIdsAsync()
    {
        List<string> ids = new List<string> { "item_one_id", "item_two_id" };
        List<VirtualItem> virtualItems = await VirtualItemsModule.I.GetVirtualItemsByIdsAsync(ids);
    }
}

Updating Virtual Items data

using System.Collections.Generic;
using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    public async void UpdateVirtualItemInfosAsync()
    {
        string virtualItemId = "some_virtual_item";
        await VirtualItemsModule.I.SetNameAsync(virtualItemId, "New Virtual Item Name");
        await VirtualItemsModule.I.SetDescriptionAsync(virtualItemId, "New Virtual Item Description");

        List<string> newTags = new List<string> { "tag01", "tag02" };
        await VirtualItemsModule.I.SetTagsAsync(virtualItemId, newTags);
    }
}

Storing and getting custom json data :

It is possible the store and retrieve custom properties json string associated with virtual item. The json string should be UTF8 formatted string not longer than 100k characters.

using UnityEngine;
using RGN.Modules.VirtualItems;

[System.Serializable]
public struct MyCustomVirtualItemData
{
    public int MyInt;
    public string MyString;
    public float MyFloat;
}

public class VirtualItemExamples : MonoBehaviour
{
    public async void UpdatePropertiesAsync()
    {
        string virtualItemId = "some_virtual_item";

        var myCustomData = new MyCustomVirtualItemData()
        {
            MyFloat = 42.78f,
            MyInt = 51,
            MyString = "Hello World"
        };
        string propertiesJson = JsonUtility.ToJson(myCustomData);
        await VirtualItemsModule.I.SetPropertiesAsync(virtualItemId, propertiesJson);
    }

    public async void GetPropertiesAsync()
    {
        string virtualItemId = "some_virtual_item";

        var jsonProperties = await VirtualItemsModule.I.GetPropertiesAsync(virtualItemId);
        MyCustomVirtualItemData myCustomData = JsonUtility.FromJson<MyCustomVirtualItemData>(jsonProperties);

        Debug.Log(myCustomData.MyString);
    }
}

Updating and downloading the virtual item image :

using UnityEngine;
using RGN.Modules.VirtualItems;

public class VirtualItemExamples : MonoBehaviour
{
    public async void UpdateVirtualItemImageAsync(string virtualItemId, Texture2D virtualItemImage)
    {
        byte[] bytes = virtualItemImage.EncodeToPNG();
        await VirtualItemsModule.I.UploadImageAsync(virtualItemId,bytes);
    }
}

To download virtual item image you can use following code:

using UnityEngine;
using RGN.Modules.VirtualItems;
using RGN.Model;
using System.Threading.Tasks;

public class VirtualItemExamples : MonoBehaviour
{
    public async Task<Texture2D> DownloadVirtualItemImageAsync(string virtualItemId)
    {
        byte[] bytes = await VirtualItemsModule.I.DownloadImageAsync(virtualItemId, ImageSize.Small);
        Texture2D resultTexture = new Texture2D(1, 1);
        resultTexture.LoadImage(bytes);
        resultTexture.Apply();
        return resultTexture;
    }
}
