Assignment 2 – Text Based Game
Deadline: 16:00, Dec 12, 2024
1 Process For Assignment 2
Make sure you follow the process as outlined below. Assignment 2 has a different structure and a somewhat different approach to Assignment 1:
1. Clone the repo for assignment 2. (If you haven’t yet accessed gitlab. cs.bham . ac. uk do so ASAP.)
2. Download and unzip the docs . zip JavaDoc file to your own device. In the root folder open the IndexAll . html file. Read through all the package, class, method and field definitions and descriptions.
3. Complete each class in the src folder as defined in the docs.
4. The suggested order for completing classes is:
(a) All classes in org.uob. a2. gameobjects.
(b) All classes in org.uob . a2 . commands.
(c) All classes in org.uob. a2.parser.
(d) All classes in org.uob . a2 .utils.
(e) The Game. java class.
5. For each class:
(a) Complete the required code (methods and attributes).
(b) Run your code using the run. sh command, ensuring it compiles without errors.
(c) Test your code using the test . sh command. You will have errors at first but they should hopefully decrease as you progress.
(d) git add, git commit, and git push your code.
6. Keeping testing after each class is implemented until everything is working.
7. Add the required new features:
(a) Display a map.
(b) Adding a score. You can decide on the rules for how the scoring works but you need to clearly explain it in the video and game.
(c) Combining items.
2 Introduction
In this assignment, you are tasked with updating the Zork style text based game from Assignment 1(https://en.wikipedia.org/wiki/Zork). Please note that it is likely that you will need to start from scratch due to the redesign of the game, but you ARE allowed to reuse your story and and puzzles from Assignment 1.
The game is played by the user entering in various commands (e.g. "move south", "look room", "get key", "use key on chest"), to which the game responds with text based output (e.g. "You pick up the rusty key").
3 Mark allocations
You will receive marks based on two aspects of the game: Firstly, the results of run- ning the test.sh command. We will run our own version of these tests once you have submitted. This command will test each class and method (detailed as in the provided docs . zip and in Tasks 1 - 6). You need to implement all the classes and methods as described in the docs as well as any required for your new features.
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.
• Play through the game once showing all the rooms, puzzles and an example of each of the expected commands.
• Show and briefly explain the code in your Game.java file.
• Show and briefly explain your required new features.
• Show and briefly explain anything else that you did beyond the normal scope of the assignment. This includes any additional features you’ve added.
The screen recording must be shorter than 7 minutes. You can use a text-to-speech app if you do not want to record your own voice.
3.1 Minimum expected commands
The following is a completelist of commands the game must be able to parse (values in angle brackets refer to arguments given to a command, the pipe symbol refers to different options):
• move : Move to a different location as defined by an exit’s name (e.g., ’move north’).
• look |- || : Look around the current room, at an exit, at a feature, or, at a specific item, equipemnt or feature.
• get - : Pick up an item or equipment from the current room (e.g., ’get key’).
• drop - : Drop an item or equipment from your inventory (e.g., ’drop key’).
• use on|with : Use an item in your in- ventory on its own, or on a feature or item (e.g., ’use lamp’ or ’use key on chest’).
• status : Check your current status, or inventory; or get more information about a specific item or equipment in your inventory.(e.g. ’status player’, ’status inventory’, ’status key). Also able to display the map and your score.
• help : Display this help information or get help on a specific topic (e.g., ’help move’ or ’help’).
• combine and : Combine two items into a new item or equip- ment. (e.g., ’combine stick and rock’ or ’combine egg and flour’).
• quit: Exit the game.
NOTE: Some of these commands are not included in the template code and need to be added i.e. combine, status map, status score
3.2 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) features/chests.
• At least four (4) items.
• At least two (2) pieces of equipment.

5 Task 1 - org.uob. a2.gameobjects
These classes represent all the game objects (i.e. Map, Item etc.) that will be used in the game. The GameState class contains the current state of the game. The Container class represents anything that can "contain" another object. This is implemented as another hidden equipment or item in the room which is then revealed when the container is "opened". Usable is an interface that makes GameObjects usable by enforcing access to a GameObjects UseInformation attribute.
6 Task 2 - org.uob . a2 . commands
These classes represent all the commands that the player can execute in the game and that are generated from the parser package. Commands work on the object name, not the id. This package also includes an enum of all CommandTypes and an Exception.
7 Task 3 - org.uob. a2. parser
These classes convert the player’s text into into Commands that can be executed by the game. It firstly sanitises the players input to get it into a correct format. Then it converts it into Tokens using the tokenise method and finally it parses these Tokens use the parse method.
8 Task 4 - org.uob . a2 . utils
These classes read in a text file (as stored in the data directory) into a GameState Object.
An example of the file is shown below and also included in the data directory:
player:pieter map:m1
room:r1,test room,This is a test room for testing. It is bland . ,false , equipment:k0,key,An old rusty key,false,open,c1,rb1,You use the
rusty key to open the chest . Something falls to the floor. . . container:c1,chest,A solid oak chest . ,false
equipment:rb1,ruby,A red ruby,true,reveal,r1,e1,You active the
ruby! Hidden objects become visible! item:d1,diamond,A test diamond,false
exit:e1,north,A door to the north,r2,true
room:r2,second room, This is the second testing room. It is even more bland . ,false
exit:e2,south,A door to the south,r1,false
|
The explanation of each field in the file is given below:
|
player: name> map:
room:<id>,<name>,<description>,<hidden>
equipment:,,,,
target>, result>, description>
container:,,,den> item:,,,en>
exit:,,, room>,
|
9 Task 5 - Game. java
This is the main java class that reads in a GameState, parses user input and executes Commands.
10 Task 6 - New features
Displaying a map in any format you prefer using the status map command. Display the player’s score based on any rules you choose using the status score command. Combining two items using the combine command.
You may add methods and classes as required to get these features to work.
11 Submission Procedure
The general steps to take to complete the project are as follows:
• Set up your gitlabssh access using the setup-git command on vlab.
• Copy your ssh key to your gitlab profile.
• Clone the template repository for assignment 2 from your gitlab.
• 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 cleary explain what each method is doing.
• Once you have completed the code, record a short video using MS Stream. Refer to Section 3 for more information.
• Submit the video to canvas.
• Submit the latest commit hash to canvas.
• 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.
