Creating NFT Inventory

After requesting the project inventory from Xerial services, the JSON response needs to be processed to create an instance of the UserData class.

Usage

using System.Collections.Generic;
using UnityEngine;
using SimpleJSON;
using Xerial;

public class NFTResponseHandler
{
    public void HandleNFTResponse(string response)
    {

        XerialServices.instance.inventoryManager.inventory = null;

        JSONArray jsonArray = JSON.Parse(response).AsArray;

        if (jsonArray != null && jsonArray.Count > 0)
        {
            JSONNode rootNode = jsonArray[0];
//Deserialize the object array            
        }
}

Deserializing NFTs from Project Inventory Data

To deserialize the NFTs from the JSON response within the project inventory data.

NFT

First, we retrieve the node containing NFT data from the JSON response received from the server. c

NFT nft = new NFT();

int quantity = rootNode["quantity"].AsInt;
nft.amount = quantity;

JSONNode collectionNode = rootNode["collection"];
nft.collection = new Collection();

JSONNode metadataNode = rootNode["metadata"];
nft.metadata = new Metadata();
 
JSONArray tokensArray = rootNode["tokenIds"].AsArray;
nft.tokens = new List<Token>();

Collection

nft.collection = new Collection();
nft.collection.Id = collectionNode["id"].Value;
nft.collection.TxHash = collectionNode["txHash"].Value;

Metadata

nft.metadata = new Metadata();
nft.metadata.name = metadataNode["name"].Value;
nft.metadata.description = metadataNode["description"].Value;
nft.metadata.image = metadataNode["image"].Value;
nft.metadata.externalUrl = metadataNode["externalUrl"].Value;

JSONNode contractnode = rootNode["metadata"]["contract"];

nft.metadata.contract = new Contract();

nft.metadata.attributes = new List<Attributes>();
foreach (JSONNode attributeNode in metadataNode["attributes"].AsArray)
{
    Attributes attribute = new Attributes();
    nft.metadata.attributes.Add(attribute);
}

Contract

JSONNode contractnode = rootNode["metadata"]["contract"];

nft.metadata.contract = new Contract();
nft.metadata.contract.address = contractnode["address"].Value;

Attributes

nft.metadata.attributes = new List<Attributes>();
foreach (JSONNode attributeNode in metadataNode["attributes"].AsArray)
{
    Attributes attribute = new Attributes();
    attribute.type = attributeNode["type"].Value;
    attribute.name = attributeNode["name"].Value;
    attribute.value = attributeNode["value"].Value;
    nft.metadata.attributes.Add(attribute);
}

Token

nft.tokens = new List<Token>();
foreach (JSONNode tokenNode in tokensArray)
{
    Token token = new Token();
    token.tokenId = tokenNode.AsInt;
    nft.tokens.Add(token);
}

Store the NFT inventory

Create NFT Instances: For each NFT entry in the JSON data, we add an instance of the NFT class to represent the NFT inside the inventory.

if (XerialServices.instance.inventoryManager.inventory != null)
{
    XerialServices.instance.inventoryManager.inventory.AddNFT(nft);
}
else
{
    XerialServices.instance.inventoryManager.inventory = new NFTInventory();
    XerialServices.instance.inventoryManager.inventory.AddNFT(nft);
}
