Q$3$: Add a row of bricks and other features to finalize creation of Breakout.

$($DentStewA$4$Q$3.$pde$)$

In this question you will take the code you created in Q$2$ and modify it$.$ You will add a row of bricks to the top wall.

When the ball hits a brick, the brick should $$disappear$.$ The ball should bounce off

the top wall as before. This process should repeat until all of the bricks have been

hit, at which stage the screen should be greyed out and two buttons should appear.

One button will restart the game, and the other will close the window.

$$ To achieve the required funcitonalities, the following variables must be

declared.

o Constant NUM$\_$BRICKS for the total number of bricks. Choose

a value of $10$ or less, so that each brick can be identified by a

single$-$digit number.

o Constant BRICK$\_$HEIGHT.

o boolean variable gameOver to indicate that the game is over and

the buttons should appear to give the user the choice of starting a

new game or quitting.

o boolean variable exit to indicate that the program should end.

o Constants for the restart button: RESTART$\_$LEFT, RESTART$\_$TOP, RESTART$\_$WIDTH and

RESTART$\_$HEIGHT.

o Constants for the exit button: EXIT$\_$LEFT, EXIT$\_$TOP, EXIT$\_$WIDTH and EXIT$\_$HEIGHT.

o A String called brickHitNums which will store the brick numbers that have been hit by the ball.

For example, if the ball hit bricks $3$ then $7$ then $0$ then $4,$ then this String should contain $"3704".$

$$ The following functions must be created to achieve the required functionality:

o resetParameters: This function will not have any parameters and will return void. The purpose of

this function is to reset the ball position and speed, and the String brickHitNums, in order to start

a new game.

COURSE NUMBER: COMP $1010$

$4$

o boolean isInString$($String$,$ int$)$: This function should determine whether or not the String

contains the given integer digit. For example, isinString$("3704",7)$ should return true, but

isinString$("3704",6)$ should return false.

$$ Remember that $7$ and $\text{'}7\text{'}$ are different types of data. You will need to use some casting or

conversion.

$$ This function will be called by drawBricks function to determine whether or not a

particular brick has been hit.

o drawBricks: This function will be a void function with no parameters. It must perform following

tasks:

$$ Draw the row of up to $10$ bricks, as specified by numOfBricks.

$$ While drawing, determine if the ball is touching any brick. If so$,$ add that brick$$s number

to the String brickHitNum, but only if it is not already there. Use the isInString$()$

function to help.

$$ If any brick has been hit, do not draw that brick. Draw the bricks that have not been hit.

$$ If all of the bricks have been hit, update the gameOver variable to indicate that the game

is over, and that the option buttons should be presented to the user.

o displayExitOptions: The purpose of this function is to display two buttons after the game is over.

One will be labelled Restart and the other Exit. Based on which

button the user clicks, call the appropriate function and update

any appropriate variables.

o mouseClicked: Use this function to determine which button the

user has clicked.

$$ If user clicks on Restart, call the resetParameters

function to restart the game.

$$ If user clicks on Exit, use exit$()$ to stop the program.
