Some things I know about this project so far.

Running the code first, to see how the game currently operates.

Implement just one requirement at a time. For example, try implementing the case where after the user clicks 2 squares, both squares are hidden. (Then implement the other cases).

In the game, the user clicks two squares at a time. Both colors are shown, but if they don't match they are hidden again. Need help finishing and getting the objective done.

/** * Memory Game * This application is a basic memory game. The user is shown a 2x4 grid of gray squares. * A square is "revealed" when the user clicks on it - the color of the square is then shown. * Squares are gray when "hidden", and can be red, green, blue, or yellow when shown. * * The user begins by revealing 2 squares. If both squares are the same color, the squares * remain shown, otherwise the squares are hidden again (and turn gray). * * The game ends when the user has matched all of the squares (all colors are shown). */ public class Lab4 extends Application { @Override public void start(Stage primaryStage) { try { // Load the FXML file for the game board Parent root = FXMLLoader.load(getClass().getResource("/board.fxml")); // Set the scene onto the stage primaryStage.setScene(new Scene(root, 800, 400)); // Display the board to the user primaryStage.show(); } catch(Exception e) { e.printStackTrace(); } } public static void main(String[] args) { // Launches the application (calls start method in the process) launch(args); } }

Objectives: JavaFX Code tracing UML diagrams Task: Create an interactiv memoryame It's almost time for midterms, and you'll need a game to help blow off some steam. Create a basic memory game that's fun and flexes your new JavaFX skills Getting Started To begin this lab, download the Eclipse project file here: abc123-lab4.zip This JavaFX project consists of the following, and follows the MVC design pattern: Lab4.java runs the application MainController.java controller Board.java - model (represents the game board) model (represents a square on the board) . board.fxml-view Begin by downloading the code and becoming familiar with each of these classes. If you run the code as given, the following application will be presented: Each of the gray squares is hiding a color. When one of the gray squares is clicked, it will reveal the color underneath. At this time, this is all the application does. Time for you to implement the game play
