In this assignment you will get the “Shiny Buttons” game working (from assignment 5).Begin with your working code from assignment #5. Complete the game so that the following happens:1. Add a private score integer attribute to the ShinyButtons model class. Create a getScore() method
that returns the score.
2. When the user presses the New Game button, the score resets to zero and the game pieces are reset
to a different set of random colors again.3. When the user presses the Quit button, the application stops and the window closes.
4. When there is currently no selected game piece and then the user clicks on a game piece, that game
piece’s JButton becomes the “selectedButton”.Each JButton can have two ImageIcons assigned to
it: (1) the regular icon, and (2) the selected icon:
Regular Icons
Selected IconsAt this point, we have only used regular icons. You can also set a selected Icon for each JButton (i.e.,
a different image) by doing this: (aJButton.setSelectedIcon(new ImageIcon(“…”));. This just
has to be set once, when you create the JButtons. Add the following array to your code and make
sure that you download the additional 7 selected icon images (shown above).Use the array to set the
appropriate selected icon for each JButton according to its current color.
public static ImageIcon[] selectedIcons = {
new ImageIcon(“SelectedRedButton.png”),
new ImageIcon(“SelectedOrangeButton.png”),
new ImageIcon(“SelectedYellowButton.png”),
new ImageIcon(“SelectedGreenButton.png”),
new ImageIcon(“SelectedBlueButton.png”),new ImageIcon(“SelectedLightGrayButton.png”),
new ImageIcon(“SelectedDarkGrayButton.png”)
};Adjust your code so that all JButtons are NOT selected except for the selectedButton, which should
be selected. You can set aJButton to be selected by saying: aJButton.setSelected(true); JAVA
will then show the appropriate image icon automatically. As a result, the background of the button
image should be colored in to a non-white color.5. Adjust your code so that when the user has already selected a game piece, and then an adjacent game
piece is selected that lies beside (i.e., to its immediate left, right, up or down position) the selected
game piece (i.e., the selectedButton) then this piece should swap positions with the selectedButton’s
piece.Note that you should NOT swap JButtons … just game pieces. However, you WILL need to
ensure that the JButtons’ regular and selected icons are properly swapped also. Just create an
appropriate method in the ShinyButtons model class to swap two game pieces when given their rows
and columns … then update() the GUI accordingly.Once the swap is made, the selectedButton
should be set to null so that no JButtons are selected anymore. You should see the swap happen
visually on the window. If the game piece that was pressed was NOT beside the selectedButton’s
piece, then no swap is made and the selectedButton should be set to null, so that no buttons remain
selected.6. Adjust your code so that it automatically highlights any horizontal or vertical sequences of 3 or more
game pieces if they are the same color (see below).In order to determine which game pieces to highlight (i.e., to select), you will need to write some code in
the ShinyButtons class. Create the following attribute: private boolean[][] selectionTable;Create a method in the ShinyButtons class called processTable() which resets the selectionTable to
have all false values and then checks all rows for sequences of same color pieces and then checks the
columns for sequences of same color pieces. Here is some pseudocode for checking the rows:FOR each row r FROM 0 TO 7 DO {
set matches to 0
FOR each column c FROM 1 TO 7 DO {
IF (piece at (r, c) has same color as piece at (r, c-1)) THEN {
increase matches by 1
IF (matches >= 2) THEN
Select all three pieces at row r from column c-2 to column c.
}
ELSE set matches to 0
}
}Do something similar for the columns. Make sure that whenever a new game is started, then the
processTable() method is called. Also, make sure that it is called whenever two pieces’ positions are
swapped (from step 5).Now it is time to complete the game1. Write a public void cleanTable() method in the ShinyGame class that causes all selected sequences
of game pieces to be removed from the game board. As a piece is removed from a row, all game
pieces above it will drop down one row and a new game piece will appear at the top row of the board
(within the same column that the removed piece was taken away).The method should work from the
bottom row upwards and look for selected pieces to remove. Here is the pseudocode:
set newPieceAdded to FALSE
set r = 7
WHILE (r >= 0) DO {
newPieceAdded = FALSEFOR each column c FROM 0 TO 7 DO {
IF (piece at (r, c) is selected) THEN {
// move the pieces down now …
FOR each row r2 FROM r TO 1 DO {
selection of piece at (r2, c) = selection of piece at (r2-1, c)
piece at (r2, c) = piece at (r2-1, c);
}// Add a new piece
set the piece color for piece at (0, c) to a valid random color index
unselect piece at (0, c)
set newPieceAdded to TRUE
}
}
IF (newPieceAdded is FALSE) THEN
decrease r by 1
}To test this, add a private Timer timer; attribute to the ShinyButtonsApp. Add the following
Timer and its event handler within the constructor:
timer = new Timer(500,new ActionListener() {
public void actionPerformed(ActionEvent e) {
// Write code here to clean the table, process it, and then update
}});
timer.start(); // This line starts the timer which will happen every 0.5 seconds2. Finally, we need to work at getting the game to keep score. To record the score, you will need to
update your processTable() method so that whenever the number of matches is 2 or more, you
update the score. Make sure to update the score for both rows and columns, separately.Each time
you find a sequence of 3 or more similar colored buttons, you will update the score as follows (where S
is the size of the sequence):
S-1
score = score + 30 + Σ (i*30)
i=3So, for example, here is the increase in score that should occur depending on the sequence size:
Sequence Size 3 4 5 6 7 8
Score Increase 30 120 240 390 570 780Make sure to test your code carefully. However, it will be hard to test sequences of 6, 7 or 8 … these
can only occur my chance if new buttons are added to a row/column which happen to match the others
in the row. However, you should be able to test sequences of size 3, 4 or 5. Please note, though, that
this game never ends … so the score will increase until the user quits.Keep in mind that nothing special needs to happen with horizontal and vertical sequences that cross.
For example, in the picture above you will notice a yellow vertical sequence of 4 (worth 120 points) and
two horizontal sequences of 3 (worth 30 points each). Hence, for these 8 connected yellow pieces, the
score will only be 120 + 30 + 30 = 180. Similarly, the 5 piece horizontal sequence of dark gray buttons
is worth 240 points and the crossing vertical sequence of 3 is worth 30 points.NOTE: Submit all .java and .PNG files needed to run. You MUST NOT use packages in your code, nor projects.
Submit ALL of your files in one folder such that they can be opened and compiled individually in JCreator. Some IDEs
may create packages and/or projects automatically.You MUST export the .java files and remove the package
declaration at the top if it is there. Do NOT submit JCreator projects either. JUST SUBMIT the JAVA FILES and PNG
files.Note that if your internet connection at home is down or does not work, we will not accept this as a reason for
handing in an assignment late … so make sure to submit the assignment WELL BEFORE it is due !Please NOTE that you WILL lose marks on this assignment if any of your files are missing. You will
also lose marks if your code is not written neatly with proper indentation. See examples in the notes
for proper style.
