The Code

class DifficultyCard : Card
    {
        protected string CardType;

        public DifficultyCard()
            : base()
        {
            CardType = "Dif";
        }

        public DifficultyCard(int cardNo)
        {
            CardType = "Dif";
            CardNumber = cardNo;
        }

        public override string GetDescription()
        {
            return CardType;
        }

        public override void Process(CardCollection deck, CardCollection discard, CardCollection hand, CardCollection sequence, Lock currentLock, string choice, int cardChoice)
        {
            int ChoiceAsInteger;
            if (int.TryParse(choice, out ChoiceAsInteger))
            {
                if (ChoiceAsInteger >= 1 && ChoiceAsInteger <= 5)
                {
                    if (ChoiceAsInteger >= cardChoice)
                    {
                        ChoiceAsInteger -= 1;
                    }
                    if (ChoiceAsInteger > 0)
                    {
                        ChoiceAsInteger -= 1;
                    }
                    if (hand.GetCardDescriptionAt(ChoiceAsInteger)[0] == 'K')
                    {
                        Card CardToMove = hand.RemoveCard(hand.GetCardNumberAt(ChoiceAsInteger));
                        discard.AddCard(CardToMove);
                        return;
                    }
                }
            }
            int Count = 0;
            while (Count < 5 && deck.GetNumberOfCards() > 0)
            {
                Card CardToMove = deck.RemoveCard(deck.GetCardNumberAt(0));
                discard.AddCard(CardToMove);
                Count += 1;
            }
        }
    }

New Variables

The DifficultyCard class declares a protected variable called 'CardType' as a string. Protected means it will be available in any subclass of DifficultyCard.

Constructors

The DifficultyCard class has 2 constructors, again this is okay as long as they have different parameters:

        public DifficultyCard()
            : base()
        {
            CardType = "Dif";
        }

        public DifficultyCard(int cardNo)
        {
            CardType = "Dif";
            CardNumber = cardNo;
        }

New Methods

The DifficultyCard class adds no additional methods to the parent class.

Process Method

The DifficultyCard class does however override the process method of the parent class. Remember for this to be overridden the Process method will be marked with 'virtual' in the parent class.

This new Process method handles the in game behaviour of the DifficultyCard.
