Your task is to invent and implement an adventure game. You have been given a simple framework
(Zork1) that lets you walk through a couple of rooms. You can use this as a starting point.
1 Read The Code
Reading code is an important skill that you need to practise. You first task is to read some of the
existing code and try to understand what it does. By the end of the assignment, you will need to understand most of it.
2 Make small extensions
As a little exercise to get warmed up, make some changes to the code. For example:
• change the name of a location to something different.
• change the exits – pick a room that currently is to the west of another room and put it to
• add a room (or two, or three, ...)
These and similar exercises should get you familiar with the game.
3 Design Your Game
First, you should decide what the goal of your game is. It should be something along the lines of: You
have to find some items and take them to a certain room (or a certain person?). Then you can get
another item. If you take that to another room, you win.
For example: You are at Pinetree Secondary. You have to find out where your computer
class is. To find this, you have to find the front office and ask. At the end, you need to find the class
room. If you get there on time, and you have found your textbook somewhere along the way, and you
have also been to the homeroom class, then you win. And if you’ve been to the Tim Hortons more than
five times during the game, your exam mark halves.
Or: You are lost in a dungeon. You meet a dwarf. If you find something to eat that you can give to the
dwarf, then the dwarf tells you where to find a magic wand. If you use the magic wand in the big cave,
the exit opens, you get out and win.
It can be anything, really. Think about the scenery you want to use (a dungeon, a city, a building, etc)
and decide what your locations (rooms) are. Make it interesting, but don’t make it too complicated. (I
would suggest no more than 5 rooms.)
Put objects in the scenery, maybe people, monsters, etc. Decide what task the player has to master.
4 Implement the Game
Decide what classes you need to implement the game, then implement and test them.
The base functionality that you have to implement is:
• The game has several locations/rooms.
• The player can walk through the locations.
• There are items in some rooms. Every room can hold any number of items. Some items
can be picked up by the player, others can’t.
• The player can carry some items with him. Every item has a weight. The player can carry
items only up to a certain total weight.
• The player can win. There has to be some situation that is recognized as the end of the
game where the player is informed that he/she has won.
• Implement a command “back” that takes you back to the last room you’ve been in.
• Add at least four new commands (in addition to those that were present in the code you
got from us).
• Add characters to your game. Characters are people or animals or monsters – anything
that moves, really. Characters are also in rooms (like the player and the items). Unlike
items, characters can move around by themselves.
• Extend the parser to recognize three-word commands. You could, for example, have a
command give bread dwarf to give some bread (which you are carrying) to the dwarf.
• Add a magic transporter room – every time you enter it you are transported to a random
room in your game.
