Code Programming Tutorials, Guides & Best Practices

A simple inventory system that can add, remove, and use items.

using System.Collections.Generic;
using UnityEngine;

public class Inventory : MonoBehaviour
{
    public List<Item> items = new List<Item>();
    public int capacity = 20;

    public bool AddItem(Item item)
    {
        if (items.Count >= capacity)
        {
            Debug.Log("Inventory is full!");
            return false;
        }

        if (item.isStackable)
        {
            Item existingItem = items.Find(i => i.itemName == item.itemName);
            if (existingItem != null)
            {
                // Stack logic (if needed)
                Debug.Log($"Stacking {item.itemName}");
                return true;
            }
        }

        items.Add(item);
        Debug.Log($"{item.itemName} added to inventory.");
        return true;
    }

    public void RemoveItem(Item item)
    {
        if (items.Contains(item))
        {
            items.Remove(item);
            Debug.Log($"{item.itemName} removed from inventory.");
        }
    }

    public void UseItem(Item item)
    {
        if (items.Contains(item))
        {
            item.Use();
        }
    }
}
