P3: Adventure Game in C++

An adventure game is a natural for having you test your skills at class definition. An adventure game (for those of you who have never been Zork-ed or wandered in twisty tunnels that look all the same) lets you give commands (real simple -- one or two words) to wander through a virtual world. Descriptions of the world are all in text.

Here are the constraints:

• You must have at least five rooms and ten items.
• You must use at least two different class hierarchies. One of them must be the base class Room and derived class variations on rooms. The other can be whatever you want: A Monster hierarchy, a Key hierarchy, whatever.

Your system must be able to run with the following input from the keyboard (without visiting any room twice):

north
east
take key
up
south
use key
quit

After each of these commands, some description of the room (including exits) and current state must be provided. Your game must also support the Look verb to view the description of the room (including exits) and current state. Look by itself should provide the description of the room. Every object should also respond to look, e.g., look key. You must also provide some simple error handling, e.g., for unknown commands, actions on non-existent objects, going to unavailable exits, etc. In short, no matter what a user types, your system must respond reasonably (e.g., "unknown command" or "no exit in that direction") and must not crash. The metaphor of the game, additional rooms, additional hierarchies, etc. are all up to you.

If at all possible, please provide your TA with only one .cc file which can be compiled with g++ on acme. If you need to use .h files, then provide all the files to your TA. In your writeup, please include a run of your system with the above input. You must, as always, include an OOA, OOD, and code listing. Also include a Reuse section. Also, please mail your code to your TA.

Assignments are due December 11 (during Dead Week) in class.

Discuss this assignment in CaMILE.
