Okay so, this is a small problem. I am having a hard time with a line of code from a help on here. The tip is from 2012 and it is only giving me a problem with the line 25: ** _card = Instantiate(asst, position, rotation)**
What is going that I don’t get? it is telling me I cannot change an Object to a GameObject.

    public enum SuitEnum {
        Hearts   = 1,
        Clubs    = 2,
        Diamonds = 3,
        Spades   = 4,
    }

    public class Card {
        private SuitEnum _suit;
        private int _rank;

        public SuitEnum Suit { get { return _suit; } }
        public int Rank { get { return _rank; } }

        private GameObject _card;

        public Card(SuitEnum suit, int rank, Vector3 position, Quaternion rotation) {
            // to do: validate rank, position, and rotation
            string assetName = string.Format("Card_{0}_{1}", suit, rank);  // Example:  "Card_1_10" would be the Jack of Hearts.
            GameObject asset = GameObject.Find(assetName);
            if (asset == null) {
                Debug.LogError("Asset '" + assetName + "' could not be found.");
            }
            else {
                _card = Instantiate(asset, position, rotation);
                _suit = suit;
                _rank = rank;
            }
        }
    }

    public class Deck {
        private List<Card> _deck = new List<Card>();
        private List<Card> _discardPile = new List<Card>();

        public void Shuffle() {
            /* To Do */
        }

        public Card TakeCard() {
            if (_deck.Count == 0)
                return null; // the deck is depleted

            // take the first card off the deck and add it to the discard pile
            Card card = _deck[0];
            _deck.RemoveAt(0);
            _discardPile.Add(card);

            return card;
        }

        /* ...etc... */
    }

You are calling Instantiate but your class is not a MonoBehaviour. There is no Instantiate method in this class. You should be getting an error about that. The error you mention might be because the compiler doesn’t know what that non-existing method should return so it assumes it’s a System.Object.

I think you should be calling UnityEngine.Object.Instantiate and casting that to a GameObject or you should make this class extend MonoBehaviour

All you’re missing is a cast. Try adding “as GameObject”, something like this:

    else {
                         _card = Instantiate(asset, position, rotation) as GameObject;
                         _suit = suit;
                         _rank = rank;
                     }
