My project doesn't have the InventoryUI.cs script

[UnrealStudent]

I’m working on the “RPG Inventory Systems” course, and I completed the “InventorySlotUI.cs Changes” lesson, but now when I try to play the game it gives me errors like this:

“Assets\GameDev.tv Assets\Scripts\UI\Inventories\InventorySlotUI.cs(4,17): error CS0234: The type or namespace name ‘Inventories’ does not exist in the namespace ‘GameDevTV’ (are you missing an assembly reference?)”

“Assets\GameDev.tv Assets\Scripts\UI\Inventories\InventorySlotUI.cs(9,66): error CS0246: The type or namespace name ‘InventoryItem’ could not be found (are you missing a using directive or an assembly reference?)”

It tooke me a while, but I found the source of the problem: In the next lesson about using the debugger tool, I discovered that Rick and Sam had at least one script that I didn’t: the InventoryUI.cs script. Curiously enough, I can find it in Visual Studio Code’s explorer, but it claims that the path to it doesn’t exist anymore. I know that I haven’t moved it and it wasn’t included in the builds you download at the start of course, so where do I get it?

I’m not sure why the script wouldn’t be in there, but here’s the script, you can add to your project:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using GameDevTV.Inventories;
using TMPro;

namespace GameDevTV.UI.Inventories
{
    /// <summary>
    /// To be placed on the root of the inventory UI. Handles spawning all the
    /// inventory slot prefabs.
    /// </summary>
    public class InventoryUI : MonoBehaviour
    {
        // CONFIG DATA
        [SerializeField] InventorySlotUI InventoryItemPrefab = null;
        [SerializeField] bool isPlayerInventory = true;
        [SerializeField] TextMeshProUGUI Title;

        // CACHE
        Inventory selectedInventory;

        // LIFECYCLE METHODS

        private void Awake() 
        {
            if (isPlayerInventory)
            {
                selectedInventory = Inventory.GetPlayerInventory();
                selectedInventory.inventoryUpdated += Redraw; 
            }
        }

        private void Start()
        {
            if(isPlayerInventory)
            {
                Redraw();
            }
        }

        public bool Setup(GameObject user)
        {
            if (user.TryGetComponent(out selectedInventory))
            {
                selectedInventory.inventoryUpdated += Redraw;
                Title.text = selectedInventory.GetDisplayName();
                Redraw();
                return true;
            }
            Debug.Log($"{name} does not have an inventory attached.");
            return false;
        }

        // PRIVATE

        private void Redraw()
        {
            foreach (Transform child in transform)
            {
                Destroy(child.gameObject);
            }

            for (int i = 0; i < selectedInventory.GetSize(); i++)
            {
                var itemUI = Instantiate(InventoryItemPrefab, transform);
                itemUI.Setup(selectedInventory, i);
            }
        }
    }
}

There we go, now my project is working fine. Thanks for the response!
