Question

Practically dying here with this, need help ASAP, just need to do hide(), hideBoth(), and matchFound(), then implement them, so far in my version i tentatively made them, but I don't know ho to implement them so i posted the original code before i made my version of the three methods listed above. Need help fast, this is ridiculous.

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. ___________________________________________________________ Lab4.java ___________________________________________________________ package application; import javafx.application.Application; import javafx.fxml.FXMLLoader; import javafx.stage.Stage; import javafx.scene.Parent; import javafx.scene.Scene; /** * Memory Game * This application is a basic memory game.

Answer 1

Please find the Board.java below.

CODE

============================

import javafx.scene.paint.Color;

public class Board {

private Square[][] squares;

public Board() {

this.squares = new Square[2][4];

squares[0][0] = new Square(Color.RED);

squares[0][1] = new Square(Color.BLUE);

squares[0][2] = new Square(Color.GREEN);

squares[0][3] = new Square(Color.YELLOW);

squares[1][0] = new Square(Color.GREEN);

squares[1][1] = new Square(Color.RED);

squares[1][2] = new Square(Color.YELLOW);

squares[1][3] = new Square(Color.BLUE);

}

public void hide( int x, int y ) {

squares[x][y].hide();

}

public void hideBoth(int x1, int y1, int x2, int y2) {

hide(x1, y1);

hide(x2, y2);

}

public boolean matchFound(int x1, int y1, int x2, int y2) {

if(reveal(x1, y1).equals(reveal(x2, y2))) {

return true;

}

hideBoth(x1, y1, x2, y2);

return false;

}

public String reveal( String buttonName ) {

int x = buttonName.startsWith("zero") ? 0 : 1;

int y;

if( buttonName.endsWith("zero") )

y = 0;

else if( buttonName.endsWith("one") )

y = 1;

else if( buttonName.endsWith("two") )

y = 2;

else

y = 3;

return this.reveal(x,y);

}

public String reveal( int x, int y ) {

squares[x][y].reveal();

return squares[x][y].getColorAsCode();

}

/**

* ToString method returns a String representation of the current state of the game board.

* @return String Board colors currently revealed.

*/

public String toString() {

String ret = squares[0][0] + ", " + squares[0][1] + ", ";

ret += squares[0][2] + ", " + squares[0][3] + "\n";

ret += squares[1][0] + ", " + squares[1][1] + ", ";

ret += squares[1][2] + ", " + squares[1][3];

return ret;

}

}

How to Use

==============================

To use matchFound(), you need to obtain the value of x1, y1, x2, y2.

You can refer to reveal(String button) function to see how to obtain the value of x and y of a square.
