IMPLEMENTATION OF A SLOT MACHINE

Usage Instructions: Doubleclick the .jar file in Windows or run from the command line by typing java -jar SlotMachine.jar

DIVISION OF RESPONSIBILITIES

In the very first few days of receiving the assignment, Edward put together a rudimentary Backend with a Board.java, Player.java, and Reel (including a virtual reel). Jesse took over the Backend from there and did some heavy lifting by implementing the SpinResult Enum, calculating the payouts in SlotMachineImpl, etc.

Jesse continued to hammer out the Backend while Edward began to design the UI in Photoshop. Once the UI was designed, Edward went to work implementing the GridBagFrame. Jesse added a considerable amount of Code to the GridBag, such as the MultiThreading in reelSpin().

They both did the MouseHandler events while Edward did the Menu Items and associated action listeners. It was Jesse's idea to create the SlotMachineConstants.java class.

BACKEND / GAME LOGIC

File	Description
Board.java	Creates a 2D array that is an abstraction of the 3 x 3 slot machine window.
Payout.java	Allows the developer to change the payouts very quickly and determine whether a line is a winner.
Player.java	Functions for setting an account balance and player name. Also implements a JOPtionPane to prompt player for name when a new game is created.
SelectedRow.java	Toggles a payline row on or off.
SlotMachineConstants.java	Provides static constants for use throughout the program.
SlotMachineImpl.java	Receives the spin results from board[][] and determines whether a particular row is a winner. Then it calculates the payout.
SpinResult.java	Enum which defines the "tokens" (such as Lucky7, Java, BAR, etc.). Assigns a name of the token, a number on the virtual reel, and strings which correspond to the position of the images.

MENU ITEMS

File	Description
FileMenu.java	Extends JMenu. Constructor adds File to the JMenu.
LoadItem.java	Extends JMenuItem. Constructor adds "Load game" to the JMenu. Load's a file with a FileChooser object.
NewGameItem.java	Extends JMenuItem. Constructor adds "New game" to the JMenu. Prompts player for name and creates an opening balance of $100.
QuitItem.java	Extends JMenuItem. Calls System.exit().

USER INTERFACE

File	Description
SlotMachine.java	Main class for running the game.
SlotMachineGridBagFrame	extends JFrame. Provides the UI for the slot machine. Constructs a gridBagFrame that is 8 x 8 for 64 total, equal 1 inch X 1 inch squares. Squares at X = 7, Y = 0,1 have been converted into one JEditorPane which displays the Player's current account balance. We use HTML to set the background of the Pane and light CSS to format the text.

TESTING

File	Description
AdapterMock.java	Test class for slot machine logic

EXTRA CREDIT

Not only did we implement a save and load game feature using Java's FileChooser, we also used MultiThreading in SlotMachineGridBagFrame.java in order to give the effect of a spinning reel.
