project history

 (pconrad) Poker Game | W14 | W16 | M16

Playing the Game

To start the game, type the command

ant run

Game Options :

• Play Single Player : Play versus the computer

• Create Poker Server : Host a socket server on the local machine for a poker game and tells you the IP Address needed for other players to join the server. In order to personally join the server you just created, open a new terminal window, type the command 'ant run' again, and then click "Connect to Poker Server." Further instructions below. (This has temporarily been removed in favor of creating a better PokerGame)

• Connect to Poker Server : Connect to an open poker server. Enter "localhost" or "127.0.0.1" into the prompt textbox to join your own server. Otherwise, enter the IP address of the host you want to connect to (IP address given to the host after creating the server). (This has temporarily been removed in favor of creating a better Poker Game)

• Create Poker Chat Server : Host a socket server for the chat program.

• Connect to Poker Chat Server : Connect to an open poker chat server. Connecting to the chat server works the exact same way as the above 'Poker Server'.

Code Assessment

The code is seperated into a multitude of classes.

• The PokerMain class sets up the menu that you first see when the game starts up. It creates three buttons and does the event handling for them as well.
• One of the buttons creates a PokerServer, which is defined in the PokerChatServer class. This class tries to create a server socket at port 14040. Then, after finding out your IP address using a website (line 45), it prints out your IP address to the stream. The socket continues running indefinitely. Should anything fail, the location of the failure in the code will be printed.
• Another button creates the PokerChatClient. BEFORE the PokerChatClient is created, PokerMain asks for the IP address of the server youre try to connect to. THEN is creates PokerChatClient. This class then sets up a GUI that asks for a username. Then, it tries to create a socket at port 14040. once it is Setup, the ChatBox GUI is set up. The methods inside deal with receiving and sending message as well. Unlike PokerChatServer, PokerChatClient can be exited.
• The last button starts up a new PokerSinglePlayer.
• PokerSinglePlayer is a subclass of PokerGame. The GUI for PokerSinglePlayer is kept in the PokerGameGUI class. this class is also a subclass of PokerGame.
• When the "Play Single Player" button is pushed in PokerMain, first, PokerSinglePlayer sets the chips for the player and the computer opponent. Next, inside the go method, PokerGame's setup method is called. This method makes the player and opponent bet 5 chips to set up the Ante of 5 chips. this "bet" method is located inside of the Player class. Now that the setup method has been called, layoutSubviews and controlButtons is called. both of these methods are located inside of PokerGameGUI.
• The card class creates all 52 cards, assigning them each a suit and a number. Aces have the value "14" as opposed to "1". The deck class puts all 52 cards into an array, and handles shuffling and drawing cards from the deck.

M16 final remarks

Poker Single Player begins to follow a "Factory Design" pattern for PokerGame. Deck is in charge of the deck, Hand is in charge of the player's hand, Player has a hand, TableCard holds the table cards, Poker Game holds Players, a Deck, and TableCards. When we rewrote the Poker Game just for a single player, we completely got rid of our multiplayer version in favor of an understandable design. This is where you come in, we left a good basic heirarchy of the single player game and we want you to extend our PokerGame class to create the multiplayer aspect of the game through the server. See the many issues we created last year and see which ones you can tackle. Feel free to restart the idea of the Chat Button, we kept it there because it had no influence with the Single Player game when we rewrote the code. A good idea is that you should develop a better server with a hierarchal structure to make the PokerServer (aka MultiPlayer Server). Future improvements and ideas that you can do are improving the GUI layout and creating a new class to take on GUI responsibilities of the PokerGame. You can add better animations to the cards (and maybe even poker chips)! The rules sheet opens in a new window, rather, you can add it directly within the PokerGame. You can also integrate chat with the multiplayer game and disable it from the singleplayer mode. This game actually has tons of room for improvement and we can't wait to see what you come up with!

F16 final remarks

To learn about the code, please refer to the code assessment section above. Overall, we have tried to move the code towards setting up a good base for future features. We separated the PokerSinglePlayer into two classes: one that contains the logic, and one that contains the GUI. The PokerSinglePlayer extends GUI, and GUI extends PokerGame. We also made some minor improvements to the gameplay, such as randomizing who gets to bet first and adding the rules image inside of the game itself. Originally, we wanted to add a multiplayer. However, as it stands, PokerServer and PokerClient need a major revamp before that can be done. Please refer to those issues for more information. The first thing we recommend you tackle is improving the CompareHands class. After we created a test class, we discovered that it contains some bugs. We got rid of some major bugs but there’s still a lot of room for improvement. Please read the issue we left for more information on that. From then on, it is up to you whether you want to continue improving single player, or to begin adding more features. Should you choose to improve single player, consider taking the AI out of Poker Single Player and making it its own class. Our dream for this game was to create a multiplayer that allowed you to chat with the players while you played with them. There’s so many different directions you can take with this game, but remember that it is more pertinent to fix present bugs and design issues than it is to add features.

F17 Final Remarks

For an assessment of the basic program structure, please refer to the code assement section above. In addition to fixing some relatively minor issues, such as Javadoc generation and comments, we tried to improve CompareHands and make it easier for the (currently single player only) game to be extended to include multiplayer functionality.

Minor Issues Fixed:

• Added Javadoc comments - added comments to much of the code base
• Added Javadoc publishing to Github Pages - javadoc can now be published online using Github Pages
• Added message displaying winning hand - Added a method to CompareHands to help display the winning hand at the end of a round. Because this method affects the GUI, a possible area of improvement could be to move this behavior into PokerGameGUI or some other GUI class.

Major Issues Fixed:

• CompareHands tie handling - improved how CompareHands handles ties, decreasing bugs
• Seperated OpponentAI from PokerSinglePlayer - We made it easier to add multiplayer functionality by creating and two new concrete classes, User and OpponentAI, each inheriting from a common abstract class, Player. User and OpponentAI contain exactly the same methods, with the only difference being in how takeTurn() is implemented. In user, it simply instructs the GUI to wait for user input. In OpponentAI, it executes the current poker AI algorithm. The AI algorithm is currently extremely easy to beat, and is definitely another area that can be improved.

Since Users and AIs can both be thought of as Players, extending the code to multiplayer should be easier since all players can be referred to using Player references, regardless of whether or not the player is a user or AI.

Recommendations:

Because of the current state of the code base, we recommend refactoring the code for multiplayer before adding new features. Currently, the assumption that the game has only 2 players is reflected in much of the logic and much of the existing code requires significant refactoring to support multiplayer. Some of the issues, such as incorporating the chat server into the game GUI window, are only truly relevant if multiplayer has already been implemented. Additionally, the implementation for new features will likely differ depending on whether or not the game supports multiplayer. Adding too many features without adding multiplayer might make the code too dependent on the assumption that there are only two players for it to be feasible to be extended to multiplayer. One piece of general advice about refactoring the code to allow multiplayer is don't be surprised if you find yourself changing much (or most) of the code. As has been previously stated, the most of the existing code assumes only two players. Adding multiplayer requires significant change to existing code, showing how programming to implementations instead of interfaces can result in a program both difficult to maintain and extend.
