*Rules*
1. For each class refer to its corresponding test to verify field and method naming
conventions.
2. Although there are many ways to construct an application, you are required to
adhere to the rules stipulated below (to achieve marks).
3. If variable names are not stipulated, you can use your own names for variables.
This shows that you have written the application (we will check for plagiarism).
4. Inclusion of extra imports is strictly prohibited and will lead to a substantial
penalty. You are restricted from using external libraries or any libraries that are
not pre-included in the provided skeleton code.
5. Do NOT change or modify files included in the "test", "lib" or "out" folders.
6. Do NOT modify the template code. However, you are allowed to create your own
methods if they are needed.
7. You MUST complete this assignment independently, producing your own code –
Do NOT discuss or share your code with others. Any use of external generative-
AI or code source is prohibited. Any cheating behaviour will result in a zero score
for this module and will be subject to punishment by the University.
8. It is *STRONGLY ADVISED AGAINST* utilizing any translation software (such
as Google Translate) for the translation of this document.
9. The jUnit tests included in the skeleton code are basic and only scratch the surface
in evaluating your code. Passing these tests does not guarantee a full mark.
10. Wrong file structure leads to a substantial penalty. Make sure you have followed
the Submission Instructions on the Assignment 1 Canvas page.
11. Make sure you complete all the required sections.
12. Make sure you have pushed the version of your code that you want marked to
gitlab.

1 Introduction
In this assignment, you are tasked with creating a basic text-based game in the style of
Zork (https://en.wikipedia.org/wiki/Zork)
The game is played by the user entering in various commands (e.g. "move south",
"look", "search chest", "get key"), to which the game responds with text based output
(e.g. "You pick up the rusty key").
You need to create your own narrative or story for the game. This narrative can be
of any genre: science-fiction, cosy cooking game, fantasy, detective noir, etc. The game
consists of "rooms" or "areas" which the player can travel to and perform actions in.
Your game also needs to present puzzles to the player. Puzzles involve the player
using an item in their inventory. The game will also provide the player with a score
based on how many "rooms" they have visited and how many puzzles they have solved.
Finally, the game also needs to display a text-based map of the game world as the
player is exploring.
2 Mark allocations
You will receive marks based on two aspects of the game: Firstly, the results of running
the test.sh command. We will run our own version of these tests once you have submit-
ted. This command will test each class and method (detailed as Task 1 - 6). You need
to implement all the classes and methods shown in the Task sections.
Secondly, you will need to submit a screen recording showing you playing the game
and discussing the code. Your screen recording needs to have the following:
• Show your face and your student card or any other valid proof of identity (e.g.
Passport or drivers license).
• Play through the game once showing all the rooms, puzzles and an example of
each of the expected commands. Do this in the order given in Section 2.1
• Show and briefly explain the code in your Game.java file.
• Show and briefly explain anything additional, innovative, or interesting you did
in the game.
The screen recording must be shorter than 5 minutes. You can use a text-to-speech
app if you do not want to record your own voice.
2.1 Minimum expected commands
The following is a minimum list of commands the game must be able to parse (values
in angle brackets refer to arguments given to a command):
4
• "move <direction>" - (<direction> can be "north", "south", "east", "west"). The
player moves to a new room based on the direction.
• "look" - Displays a description of the room the player is in.
• "look <feature>" - Displays a more detailed description of a feature in a room.
A feature is a fixed object in the room.
• "look <item>" - Displays a description of an item. This should only work if the
item is in the player’s inventory.
• "inventory" - Displays a list of all items the player has obtained.
• "score" - Displays the user’s current score.
• "map" - Displays a text-based map of the current explored game world.
• "help" - Displays a help message.
• "quit" - Quits the game.
2.2 Additional commands
You need to add additional commands of your choice for the puzzles you will create.
For example, "open toolbox" will open a toolbox. Then "take crowbar" will take the
crowbar out of the toolbox and put it into the user’s inventory.
You can create any other additional commands you want so long as they make log-
ical sense in your game. You need to use these additional commands to create your
puzzles.
2.3 Minimum game requirements
The following are the minimum requirements for the game. You are welcome to add
more if you want to:
• At least ten (10) unique rooms or areas.
• At least two (2) puzzles.
• At least four (4) items.
3 Task 1 - Position.java
The Position class stores an position in terms of an x and y value. The required methods
are:
• public Position(int x, int y)
The x and y fields need to be declared as public so that other classes can access
them directly.
5
4 Task 2 - Room.java
The Room class stores information about a Room, including a name, description, a
symbol and a Position. The required methods are:
• public Room(String name, String description, char symbol, Position
position)
• public String getName()
• public String getDescription()
• public char getSymbol()
• public Position getPosition()
The symbol is used when displaying the room on the map.
5 Task 3 - Map.java
The Map class stores information about the game Map, including the map array, a width
and height, and the value used for empty map areas. The required methods are:
• public Map(int width, int height) (this represents the rows and columns
starting at the top left of the map)
• public void placeRoom(Position pos, char symbol)
• public String display()
Declare the empty area value as follows: final private char EMPTY ='
.
';
6 Task 4 - Inventory.java
The Inventory class stores the player’s inventory, and is essentially a wrapper around an
array. It includes the maximum items you can store, the current number of items stored
and an array to store the items in. The required methods are:
• public Inventory()
• public void addItem(String item) Adds an item to the array if there is
space.
• public int hasItem(String item) Returns the position of the item in the
array if it is in the array. Otherwise it returns -1
6
• public void removeItem(String item) Removes a specified item while
ensuring there are no empty elements in the array.
• public String displayInventory() Returns a String of all items sepa-
rated by spaces (note that there is a space after the last item as well).
Declare the maximum size as follows: final int MAX_ITEMS = 10;
7 Task 5 - Score.java
The Score class stores and calculates the player’s score. It includes the starting score,
the current score, the number of rooms visited, the number of puzzles solved and the
score per puzzle. The required methods are:
• public Score(int startingScore)
• public void visitRoom()
• public void solvePuzzle()
• public double getScore() Calculates and returns the current score. The
score is calculated as the starting score minus the number of rooms visited plus
the number of solved puzzles times the score per puzzle.
Declare the score per puzzle as follows: private final int PUZZLE_VALUE
= 10;
8 Task 6 - Game.java
The Game class runs the main game loop. You can create any methods you feel you
require but you need to use all the other classes to make the game work. The only
required method is:
• public static void main(String[] args)
You can write this code in any way you want to but here is a hint for a possible
approach:
• Create some Room objects to store information about each Room in your game.
• Create Inventory and Score objects.
• Use a while loop for the main game loop.
• Inside this loop use an if statement to check what commands the user has typed.
Based on the command, the Room the user is in and what items the user has in
their inventory output a different response and update the Inventory, Score and
Map information if appropriate.

9 Submission Procedure
The general steps to take to complete the project are as follows:
• Set up your gitlab ssh access using the setup-git command on vlab.
• Copy your ssh key to your gitlab profile.
• Clone the template repository from your gitlab.
• Do not change any of the code in the template but you may add to it.
• Work on your code, testing it regularly. Use the run.sh script to run the code as
this builds the code correctly as well.
• Use the test.sh script to test your code. This will give you an output similar to
what we will use to mark the code.
• Make sure you commit and push regularly as well.
• Make sure to add comments to your code to clearly explain what each method is
doing.
• Once you have completed the code, record a short video using MS Stream. Refer
to Section 2 for more information.
• Submit the video to canvas.
• Submit the latest commit hash to canvas.
• You will receive an automated message indicating whether we are able to mark
your code.
• If there are no problems you are done with the assignment.
• If there are problems with your submission, update it accordingly and resubmit
the latest commit hash.
