How to setup

1. Extends from StoreSO

Override at least abstract method. You should take of saving your data in persistent memory. There are basic methods required to implement in the example below.

using System;
using System.Collections.Generic;
using Sirenix.Serialization;
using UnityEngine;
using UniRx;
using Project.Store;
using BigInt = System.Numerics.BigInteger;

[CreateAssetMenu(fileName = "MyStore", menuName = "Store/MyStore")]
public class MyStore : StoreSO
{
    [OdinSerialize, NonSerialized]
    public ReactiveProperty<BigInt> balance = new ReactiveProperty<BigInt>();

    public override IObservable<Price> OnBalanceChanged(string currency)
    {
        return balance.Select(x => new Price(currency, x));
    }

    public override BigInt GetBalance(string currency)
    {
        return balance.Value;
    }

    protected override void SpendBalance(string currency, BigInt amount)
    {
        balance.Value -= amount;
    }
    protected override void ApplyPurchase(List<IStoreSellable> sellables)
    {
        // Apply purchase here
    }
}

2. Create instance of the new ScriptableObject MyStore

Create instance and do setup. You can add as many currencies as needed. Also you can use it without currencies at all, if you just need to handle in-app purchases.

3. Add StoreInstaller to any gameObject

How to show sellable item(s) in UI

This system is quite independent, but you need to show sellable items for a user, to make ability for a user to buy them. There are multiple ways to do that.

• create prefab for drawing UI element which represent single item for selling. If you need you can use multiple prefabs for different reasons in different places
• add StoreSellableDrawer_UGUI component to the prefab
• bind all required elements to the component

It can be used for showing single sellable item.

Adapters

Adapter generates multiples items, very easy to setup all of them from single place with small amount of setup steps.

• StoreCategoryAdapter - shows list of sellable items from specific category
• StoreCustomAdapter - shows custom list of sellable items
• Or create your own StoreAdapter, for that need to extand from StoreAdapter. Also you may create custom StoreSellableDrawer for any UI system in case if you don't use Unity UI.

How to show player's current currencies balance in UI

CurrencyBalanceDrawer_UGUI_TMP show currency balance and refreshes it when it changed.

How to show separate price of specific sellable item

That is easy. Just create any gameObject with Text component and add PriceDrawer on it.
