Instructions to
Students
1. This assignment
should be done by each individual student.
2.
You are required
to apply Object-Oriented Programming Techniques in this assignment.
3. Plagiarism will
be treated seriously. All assignments that have been found involved wholly or
partly in plagiarism (no matter these assignments are from the original authors
or from the plagiarists) will score Zero marks. You will be asked
a random question on your program to verify that your submission is your own
work.
4. Your program
must use JDK 1.8 or above to develop.
5. Your program
must be structured and well documented. The first few lines in the source file
must be a comment stating the name of the source file, and the name, course,
class, student number as well as the main methods of the program. Marks will be
deducted if such comments are not included.

Set All to Zero
Problem Specification
In this assignment, you are required to implement a board
game. The game board is a 2-D matrix of
integer loaded from file. The goal of
the game is to set all the integers in the matrix to zero by applying different
items to the game board, different items have different properties and cost
(step count). There is no limit in steps
taken, but if the item set any value in the matrix to negative number, the game
will over.
Game Flow
A game file is required to specify in the command line to
start the game, following is an example:
|
> java Game game01.txt |
The file described the height, width, content and target
step of the game, following is an example:
|
game01.txt 5 5 1 1 1 1 0 1 0 0 1 0 1 0 2 4 2 1 1 4 1 2 0 0 2 2 2 4 |
remark // height of the
matrix // width of the
matrix // line 0 of the
matrix // line 1 of the
matrix // line 2 of the
matrix // line 3 of the
matrix // line 4 of the
matrix // target step |
After the game is initialized,
it starts to ask user to apply different items to the game board. Item can be described by a 2-D matrix of
integer, the default setting of an
Item will print the number stored on screen, except 0 will be replaced by a
space. For example,
|
data
stored in item 1 1 1 1 1 0 0 1 1 0 0 1 1 1 1 1 |
the
way to display item 1 1 1 1 1 1 1 1 1 1 1 1 |
but it can be overridden according to the needs of different
item type (will be explained in detail later).
There are two types of item, they are Bomb and SuperBomb,
Bomb shared the same display property of Item, it costs 1 step to apply Bomb on game board. When a Bomb is applied to the game board, the
value in the game board will be reduced by the corresponding value in the
Bomb. For example,
|
If is applied to 2,1 of the game board 1 1 1 2 2 2
2 2 1 2 1 2 2 2 2 2 1 1 1 2 2 2 2 2
2 2 2 2 2
2 2 2 2 2
i.e.
row is 2 and col is 1, the game board will become 2
2 2 2 2 2
2 2 2 2 2
1 1 1 2 2
1 0 1 2 2
1 1 1 2 |
SuperBomb behave differently, it costs 2 steps
to apply SuperBomb on game board. When a
SuperBomb is applied to the game board, the value in the game board will be
divided by the corresponding value in the SuperBomb. For example,
|
If is applied to 2,1 of the game board 2 2 2 3 2 3
4 3 2 1 2
3 2 3 4 3
2 2 2 3 1 2 3 3
3 3 4 4 3
3 5 6 7 3
i.e.
row is 2 and col is 1, the game board will become 3
2 3 4 3 3
2 3 4 3 3
0 1 1 3 3
1 4 2 3 3
2 3 3 3 |
In this version, SuperBomb only
stored 2 values, either 2 or 1. The
display property of SuperBomb is different from the Item’s default. 2 will be displayed as * and 1 will be
displayed as space. For example, the
SuperBomb above will be displayed as follow:
|
data
stored in item 2 2 2 2 1 2 2 2 2 |
the
way to display item * * * * * * * * |
Player is asked to apply an item to the game board
repeatedly until the player win the game or the game is over. Player wins the
game when all the values in the game board are zero and the game is over when
there is a negative number in the game board.
There are two conditions when player wins:
Condition
1: Step count <= target step count
Condition
2: Step count > target step count
For Condition 1, it displays "Congratulation, well done!" and the game will be
ended. For Condition 2, it displays "Congratulation, you have finished
the game... but you can do even better!" and player will be
asked if he/she want to play again.
When the game is over (player lose), it displays "Game Over!" and
also the game board. Note that, negative
value will be replaced as "X"
and player will be asked if he/she want to play again too.
If the player choose to play again, the game including the
step count will be reset and start again.
Otherwise the game will be ended.
Note that, "Bye
Bye!" will be printed when the game ends.
To simplify the game, the item
list is fixed in this version, there are 6 Bombs and 3 SuperBombs, their matrix
and id are stated as follow:
|
Items 0 1
2 3 4
5 6 7
8 ----------------------------------------------------------- 1
1 1 1 1 1 1 1
1 1 1 1
1 * * * * * *
* 1 1
1 1 1
1 2 1 1 1 *
* * * * * * * 1 1
1 1 1 1 1
1 * * * * * *
* 1
1 1 1 |
Player can use the items as many
time as they wanted.
Following are some sample output without error and exception
handling.
