The end result of the project is a text adventure game.

The goal of the project is to give you the opportunity to synthesize much of what you have learned this semester by working on a larger programming task.

Also, for the first time in the course, you will be responsible for making many specification and design decisions.

In fact, the project is structured in two parts:

• 80% of your mark is for completing a basic set of requirements (referred to as the baseline requirements in this handout)
• 20% is for adding further enhancements of your choosing.

NOTE:The docstring for load_map has been slightly modified as of Tuesday, November 17.
You now have the option to store the map as a nested list of strings.
e.g. The map
1 2 5
3 -1 4
becomes [['1','2','5'], ['3','-1','4']]OR [[1,2,5], [3,-1,4]]. It must be either one of these.

Working with a Partner

It is highly recommendedthat you work with a partner for this project. You may work alone or in groups of two. Pair programming and the ability to get assistance from a partner are significant advantages and will help you better understand the material. You may only discuss your assignment with this partner (if you have one) or the course staff (TAs, instructors).

Please make sure to form a group on MarkUs. You must form a group and submit only one copyof your submission.
To form a group, one of you must invite the other to join. Then, the other student who is invited must accept the invitation.

To work by yourself, choose the option to Work Alone on MarkUs.

The Story

For this project, you are to write a small-scale adventure game that takes place at your campus at the University of Toronto. The plot is as follows.

Youve got an important exam coming up this evening, and youve been studying for weeks. Last night was a particularly late night on campus. You had difficulty focusing, so rather than staying in one place, you studied in various places throughout the building as the night progressed. Unfortunately, when you woke up this morning, you were missing some important exam-related items. You cannot find your T-card, and youre pretty sure that youre not going to get into tonights exam without it. Also, you seem to have misplaced your lucky exam pen even if they let you in, you cant possibly write with another pen! Finally, your instructor for the course is nicer than your CSC108 instructors in that they are allowing you one handwritten page of information in the exam. Last night, you painstakingly crammed as much material onto a single page as humanly possible, but thats missing, too! All of this stuff must be around the building somewhere! Can you find all of it before your exam starts tonight?

If you havent played a text adventure game before, its worth messing around with one to get a feel for how it works. You can play one called Adventureonline here.

Objective

Your adventure game will allow players to try to find all of the required items prior to the exam starting.
If the player finds all of the items and brings them to the exam room before the exam starts, they win the game. (See Winning the game below for more details)

Getting Started

1. Download the available starter code here: adventure.zip
2. Unzip this file. You will now have a directory named adventure that has all necessary starter code in it.
3. In PyCharm, File > Open and select this directory.

Baseline Requirements

At a minimum, you are required to implement the following functionality:

DOCSTRINGS

You must write docstrings for all of your functions. Use either one of the two docstring styles we have covered this semester. You are welcome and encouraged to write as many helper functions as you like in order to eliminate duplicate code and make your program easier to read.

LOCATION DESCRIPTIONS

Each location in the game has an associated description. Keep in mind that a location does not necessarily have to be a room it could be a courtyard, a portion of a street surrounding the building, etc.

1. Print either a full or brief description upon each visit.
   Each time a player enters a location, they must be given a description of the location (a longer description if this is the first time the player is visiting it, a brief description otherwise). Text adventures generally display the full description of a room only once, when the room is entered the first time. Subsequent visits to the room yield only a brief description that alerts the gamer to where they are, without repeating scenery and other descriptive information.

1. Each location must have a number associated with it.
   Both the full and the brief description MUST contain the location number associated with that location as a header, e.g.: LOCATION 0
You are on the first floor of the UTM Library. There is an empty study room to the South, an exit from the library to the North.

   If printing out the location number spoils your game somehow (depends on the plot and puzzles in your game), you may choose instead to print out a unique name for the location instead, like so:

   LOCATION: UTM LIBRARY
You are on the first floor of the UTM Library. There is an empty study room to the South, an exit from the library to the North. The above would be examples of a brief description of a location.

2. Required Command: Look
   The look command prints out the full description of the current location.

1. Each location must be stored as an instance of the Location class provided in the starter code.

ITEMS

Some of the locations have items within them. These items can be taken by the gamer and carried to another location, where they can then be deposited.

1. Required Command: Inventory
   This command gives a list of what the gamer is currently carrying.

1. Each item must be stored as an instance of the Item class provided in the starter code.

MOVEMENT

Your Player must be able to move through the game world.
Adventure games generally consist of an explorer moving from location to location through a set of interconnecting corridors. From the current location, the gamer can access other reachable locations by traveling in a designated direction: north, south, east, west. Normally, corridors can be traversed in both directions; for example, if you travel east from a foyer to reach a hallway, you can generally travel west from that hallway to go back to the foyer. However, this is not always the case, especially when adventure games involve confusing, twisty or dark passages.

1. Required Commands: Go [direction]where [direction] is north, south, east, west

1. Load data from map.txt file (see starter code), and use this to determine which directional commands are available at each location.

READING FROM FILES INTO CLASSES

You are required to implement the game by writing an adventure engine that uses data files to obtain location and item information. In other words, information about the actual locations and items in your particular game should not be hard-coded, but should instead live in data files that are read by your program. (The benefit of this approach is that you can change your data files to create a new game world, without touching your source code.)

There should be three files in total storing: (1) the entire world map, (2) location data, (3) item data.

Your starter code zip includes these text files:

• map.txt
• locations.txt
• items.txt

The sample data in these text files can be removed or incorporated into your game.

MAP FILE

The map must be called map.txt and stored in the following format:

• Each location is associated with a number
• The numbers are arranged in a grid, showing their position, each number separated by a space
• The (x, y) position of these locations will be used in your code, to determine movement from one location to another
• The number -1 is used to represent non-existent areas

e.g. If the entire plot of our game takes place in an L-shaped building, we can store this in map.txt like so:

1 -1 -1
2 -1 -1
3 4 5


Here, the only accessible locations are 1, 2, 3, 4, 5. The -1 are empty areas.
So, from location 1, the player is allowed to travel only south. From location 3, the player is allowed to travel either north or east. And so on.This map must be stored in self.map in the World class as detailed in the starter code.

A note about (x,y) positions:The x-y coordinate plane here is represented with (0,0) as the top left corner. From there, x increases to the right, and y increases to the bottom. So, for the map above, location 3 is considered to be at position (0,2).

LOCATIONS AND ITEMS FILES

The format of the location and item data files is up to you and partially depends on the additional enhancements that you decide to implement.As an example for item data, we might store items in items.txt using a one line per item format, such as:

1 10 5 Cheat SheetIn this example, there are four fields: three integers followed by a string. The first field is where the item is initially located; please note that it is possible to have more than one item present at the same location. The second field is the number of the location where the item is to be deposited for credit. The third field is the number of points received for depositing the item in that credit location. The last field contains the name of the item.

As an example for location data, we might store locations in locations.txt as follows:

• Line 1: data containing location number. Locations are sequentially numbered beginning at zero.
• Line 2: number of points received for visiting this location.
• Line 3: one line (i.e. brief) description of where you are. Brief descriptions are often used when revisiting a location.
• Line 4: start of (long) descriptive text for the location. Multiple lines are permitted. The word END at the beginning of a line is used to indicate the end of the descriptive text.

For example, a location description (for the UTM Library) might look as follows. LOCATION 0
5
You are on the first floor of the UTM Library. There is an empty study room to the South, an exit from the library to the North.
You are on the first floor of the UTM Library. It's usually crowded at this time of the day, but today it's eerily quiet. Only a few students are studying inside one of the study rooms. You better not disturb them. A librarian stands near the service desk, looking bored and sleepy. There is an empty study room to the South, an exit from the library to the North.
END

Remember, you do nothave to use this format for the items and locations files.

WINNING THE GAME / LIMITED NUMBER OF MOVES

As mentioned, the gamer wins the game if they are able to bring all exam-related items to the exam room before the exam starts. In your game, you should settle on the number of moves that the gamer is allowed to make prior to the exam starting. If they exhaust their allotted number of moves, then the exam starts and the gamer does not win.You are not required to physically time the gamer. They can take as long as they like to play the game. What matters is the number of moves they make, not the actual wallclock time that elapses while they play. (Is look or inventory a move? Thats for you to decide!)

SCORE

The game should keep track of the users score. The scoring algorithm should include giving points for picking up and depositing the required exam items, as well as performing other applicable actions in the game as you see fit.

1. Required Command: Score
   This command gives the gamers current score. The scoring algorithm should include giving points for picking up and depositing the required exam items, as well as performing other applicable actions in the game as you see fit.

QUIT

Another required command is Quit, allowing the player to quit the game at any time.

Minimum Requirements Checklist

As a summary of the above, here is a checklist of minimum requirements:

• World and player data is stored within a single instance of the World class and Player class
• World map is read from map.txt, and stored as a nested list of integers/strings in World.map (the format of this must be exactly as the starter code describes)
• All location and item data is read from external files locations.txt and items.txt, and stored as instances of the Location and Item classes (the file structures and data structures used to store this info is up to you)
• Minimum required items: T-card, Cheat Sheet, Lucky Pen
• Commands (these must be the exact strings used for the commands not case-sensitive):
  • Go [direction] north, south, east, west
    Players are able to move in appropriate directions, based on map.
  • Look
    Each location has a description.
    Full description is given when look command used, or when first visiting a location.
    Else, brief description is given.
  • Inventory
    Players can pick up and drop items.
    Inventory command displays all items currently in inventory.
    Make sure only items in inventory can be used or dropped, and only items in the current location can be picked up.
  • Score
    Players must have a score which can be seen using score command.
  • Quit
    Quit command allows player to quit game at any time.
• Players total number of moves is limited
• Player can win the game
• Player loses the game if max. number of moves reached
• Required text files are complete (see What to Submit below for details)

Enhancements: Adding Puzzles and Features

To include enhancements in your project (worth 20% of the final grade), your game must have at least one fully implemented puzzle.

The functionality we have described so far moving around, taking and dropping items is one important facet of traditional adventure games. The other is the presence of puzzles that must be solved. Without puzzles, the game can be won simply by running around and picking up everything.

For a good description of the reasoning behind puzzles, and common types of puzzles, see this page all about puzzles. Some puzzles are rather elaborate, relying on performing specialized verbs on multiple items or imposing specific timing requirements. Your puzzles can be simple finding a key in a remote location from the door that it opens or more complex. Regardless, implementing puzzles will require that you extend the commands you support and/or extend the information you store in your data files.

If you wish to further increase the complexity of your game, in addition to this puzzle, you could implement any additional features you like (just keep it G-rated :P).

Here are a few suggestions:

• Even more puzzles!
• Allow the gamer to save their game to a file and restore it later. That way, they dont have to complete the game in a single sitting.
• Add more verbs (actions) that the gamer can perform. For example, you might provide a read command that gives an appropriate admonishment when used on unreadable items, but gives clues if used on a book or a piece of paper. How about an examine command that lets you take a closer look at a given item? An open or unlock command for drawers, cabinets, and doors? (Most of this will require adding additional fields to your data files!)
• Give items a weight, and limit the total weight of items that the gamer can carry. (And why not add a puzzle that requires several items to be present at the same location, but which cannot be carried at the same time because they weigh too much?)

Please dont ask how many marks your enhancements will earn: we cant evaluate your code before the due date!

IMPORTANT:To receive credit for your enhancements, you mustsubmit a written description that explains how your enhancements went beyond the baseline requirements. Submit your description in a plain text file named enhancements.txt. Each puzzle should be described in one short paragraph. The descriptions of any additional features other than the puzzles should not exceed 150 words.

If you did not add enhancements, do NOT submit enhancements.txt; you will still be able to earn up to 80%.

Suggested Milestones

To help you break the project down and keep on track, here is a series of suggested milestones.

1. Settle the specification and plan your enhancements.
   The specifications provided tell you what operations your program must provide, but not all the details of how it should behave under every circumstance. Go through all of the operations and make those decisions. For example, how does the gamer indicate that they are ready to write the exam? (This could occur automatically once all of the items are in the proper place, for example.) Next, plan what your puzzle(s)/enhancement(s) will be. If you have ambitious plans, you would be wise to have some simpler enhancements in mind, just in case you get behind. Finally, you should work with your partner to create a schedule for milestone completion. Write it down and refer back to it often.
2. Decide on your input format for locations and items.
   Keeping your proposed enhancements and puzzles in mind, how will you represent locations and items in the game? You can start with our sample data formats above, but you will have to extend them as you add to the baseline requirements. (Remember that, while location/item data can be represented however you choose, the format for map.txt and for storing the map in a nested list must be done EXACTLY AS STARTER CODE DESCRIBES .)
3. Begin coding with a datafile parser.
   Get started on the load... methods in the World class. Having your code read the map, items and location data from the data files, and creating the required items in memory, is a good first step.
4. Implement the movement commands.
   Implement the directional commands (north, south, etc.) so that the gamer can travel between locations. Descriptions of locations should be displayed, including any items present there, but item manipulation itself will be left to the next milestone. Here, ensure that the gamer cannot travel in a direction that is not prescribed by your world map. For example, if a location has no exit to the north, trying to go north should yield a suitable theres no exit in that direction message or something similar.
5. Add item manipulation. This involves allowing the gamer to get and drop items. Keep an inventory of what the gamer is currently carrying, and allow them to inspect this inventory. Be sure that the gamer cannot pick up an item that is not in the current location, or drop an item that is not in their inventory. Note:you should be able to complete the above milestones using the provided World, Player, Locationand Itemclasses. For the next milestone, you may have to add to or modify these classes, or create new ones.
6. Enhancements: Add and test a puzzle and any other enhancements.
   By this time, you have had the experience of implementing the baseline requirements and you can make a better estimate as to how much work your planned enhancements will be. Put this together with how many days you have left you may not quite be on your planned schedule and decide whether to revise your plans. Then go ahead and implement your enhancements. Add any specific commands that are required to complete the puzzle and verify that the gamer cannot get around the puzzle.

What to Submit

Hand in all code and files inside your adventure project directoryas an adventure.zip file.
This should include:

• adventure.py: which should contain your main program and all helper functions you have written; make sure all required import functions are included. It is a good idea to run your program one last time before submitting; sometimes students make a mistake during last-minute improvements and submit a program that doesnt run at all.
• all .py files your adventure.py imports classes from
• map.txt, locations.txt, items.txt
• any other files required to run your puzzles/enhancements
• solution.txt, gameover.txt, enhancements.txt (described below)

Before you submit your project, place all of the files you are giving us in a new directory and try to run the game. If you receive unexpected errors, youre missing some of your required game files, and we wont be able to play the game.

REQUIRED TEXT FILES

In order to help us mark your code, you musthand in the following files.
Failure to do so means significant parts of your code may NOT get marked.

• solution.txt
  This should be a plain text file that has one command per line, from beginning of the game to victory.
  The commands in the file should be exactly as they need to be typedduring gameplay.
  Careful about typos or extra characters.
  In this solution.txt file, you must include the command INVENTORYeach time an item is picked up, and each time an item is dropped.
  You must also include the command SCOREafter some point when the score is increased.

• gameover.txt
  This should be a plain text file that has one command per line, from beginning of the game to a game over state.
  The commands in the file should be exactly as they need to be typedduring gameplay.
  Careful about typos or extra characters.

• enhancements.txt
  Hand this in ONLY if you added enhancements. Explicitly detail the puzzle(s) you have added to your game. Each puzzle should be described by one or two paragraphs of text, outlining what must be done to solve each puzzle. Describe any other minor enhancements within 150 words.

• Optional: You may hand in more .txt files showing any extra/special features added to the gameplay.
