This is the same interface used by the ArrayList class and others that you might be familiar with. So we can create another object, albeit not a physical one, called Strategy that takes some input and gives advice on what move to make. I first wrote this game to learn. I thought this would be cool if the button for the 'correct' move glowed to show the user what to do. This method could create a graph of the correct moves. Notice that the players and the dealer are responsible for drawing their own hands. The dealer can only have one hand, has no bank, no bet, no strategy, no card counting. For that, we'll have to have a strategy that the computer players use. How does the compiler know what CurrentHand[0] means? If he does not have Blackjack, you lose your insurance bet and play continues as usual. This is a full-featured Blackjack game with strategies and graphics and even card counting. The Strategy object is going to belong to the Player objects and each player will need an array of Hand objects players can split pairs so they may have more than one hand. You'll notice that the graph changes for each player depending on the strategy chosen. It really just boils down to the few objects outlined above with a lot of fancy code added to make the game more appealing. A Deck object would have just introduced an unneeded layer of complexity. This will have to be a judgment call on your part and that's why they pay you the big bucks. This feature was missing from the original game and if the dealer had blackjack, you just lost immediately. Going back to the design of the objects, you might be wondering why the Dealer and the Player objects don't inherit from some common object. Well that's because there is a lot of supporting code underneath this, particularly to implement the line:. Sometimes it's easier to envision the code you would like to write and then model your objects to allow it. NET windows forms programming I did mostly web stuff then. And there's a shoe from which the cards are dealt into the hands.

When I first posted this application back inI challenged everyone to improve it and provided a list of enhancements I thought were needed. Of course, if the dealer has an ace in the hole, you'll still lose immediately Then I found an article called AquaButton see Readme.

If you snooped at the code carefully, you would have noticed that there was a 'Draw' method in the Strategy class that was never used. The code has also been cleaned up a lot. Nobody took me up on the challenge so I finally got back to adding some of those features myself. But I also wanted my button to be able to take images so I wrote my own version of the button.

Feel free to use this button on its own in your applications. Well, you could do that. Without implementing IListwe would probably have to write something like CurrentHand. This allows us to use array syntax like CurrentHand[0] which really means nothing until we tell here compiler that this means the card at position 0 in the array of cards in the hand.

These objects have relationships to one another as well. My version is available by right-clicking on the playing field and selecting the 'Strategy Window' option from the popup menu. To use this kind of syntax, we must implement the IList interface. But I felt the dealer and the players didn't have enough in common to justify it.

Have fun with this game. For our Blackjack game, we're going to have computer-controlled players as well as human ones.

And if the player is using the High-Low strategy, the graph can change depending on the card count High-Low is the only strategy that does this. The dealer also has a hand that has cards. Now there's a little more work real world blackjack do.

The shoe is real world blackjack to implement as an array of cards, though it must be a multiple of the number of cards in a deck Take a look at the code for this article. And since I was learning, I tried to use every feature and nuance just to see how it worked.

Right-click anywhere else to get general settings like the strategy window.

Shouldn't the Shoe be composed of many Deck objects which are composed of many Card objects? Player controls have been moved to a popup menu because I added so many that the little form window became unmanageable. Now when we deal the cards, we just go around the table taking cards from the Shoe object and adding them to blackjack banker rules Hand objects for each of the players and the dealer.

Players have hands that have cards. For IListwe need to add:. This is easily done by changing our class declaration slightly:. The dealer then looks real world blackjack his hole card and, if he has Blackjack, you are insured and lose nothing.

Anyone who's been to Vegas has probably seen one of these; They even hand them out right at the tables and real world blackjack is legal to refer to it during play. Take a look at the Readme.

When you inherit an interface, you must provide the implementation for all the methods of that interface. GetCard 0 which isn't nearly as cool! The game Blackjack lends itself well to object oriented design because it has physical objects that can be modeled in object-oriented code, i. First among those was insurance. But the most important method to implement is called Item and it looks like this:. Let's take a look at a real world example and a fun one as well. A lot of that stuff wasn't really needed and made the code more difficult to figure out and maintain. So I've streamlined it quite a bit. Initial player setup has been moved from the code to the app. You might also wonder where the Deck object is. This makes it convenient to add code to the form's Paint event like this:. Whenever the dealer shows an ace, the players are given the opportunity to buy insurance which usually costs half the original bet. That may be the case in the real world, but this is an example of where the real world and OOD might better part ways. But don't let it intimidate you. Nice code huh? Right-click on each player circle to get player-specific settings.
