Testing the Adapter pattern implementation

To test our implementation in your instance of Unity, copy all the classes we just reviewed into your project and attach the following client class to an empty GameObject in a new Unity scene:

using UnityEngine;

namespace Chapter.Adapter
{
    public class ClientAdapter : MonoBehaviour
    {
        public InventoryItem item;
        
        private InventorySystem _inventorySystem;
        private IInventorySystem _inventorySystemAdapter;
        

        void Start()
        {
            _inventorySystem = new InventorySystem();
            _inventorySystemAdapter = new InventorySystemAdapter();
        }

        void OnGUI()
        {
            if (GUILayout.Button("Add item (no adapter)"))
                _inventorySystem.AddItem(item);

            if (GUILayout.Button("Add item (with adapter)"))
                _inventorySystemAdapter.
                    AddItem(item, SaveLocation.Both);

        }
    }
}

We now can build a new inventory...
