Description
Text Adventure
You will write a very simple text adventure game. When the game is started, a “$” prompt is printed on
the screen to let the player know that he/she can type in a new command. To start playing, the player
will need to load a dungeon file which describes the rooms in your dungeon and how they are
connected. The player begins in an initial room which is specified in the dungeon file.
When the
dungeon file is loaded, the description of the initial room is printed on the screen, followed by a prompt
on the next line. Then the player can issue commands to move in a direction, either north, south, east,
or west. When a player moves, a description of the new room that he moves into is printed on the
screen and the player is prompted to enter a new move. The adventure ends when the player enters the
“quit” command.
The following is a running example showing how your program should respond to commands for an
example dungeon file. The text typed by the user is in bold.
$ loaddungeon dfile.txt
This is an open field west of a white house, with a boarded front
door.
$ north
North of House: You are facing the north side of a white house.
$ east
Behind House: You are behind the white house.
$ south
South of House: You are facing the south side of a white house.
$ quit
Dungeon File Format
The dungeon file will be a text file containing information about each room in a specific format. Each line
of the file will contain information about a single room in the dungeon. Each room is associated with the
following 6 fields of information.
1. Room number: This is a positive integer which uniquely identifies the room.
2. Description: This is a string which is printed when the player enters the room.
3. North room: This is the room number of the room immediately to the north of this room. If
there is no room to the north of this room then this value is -1.
4. South room: This is the room number of the room immediately to the south of this room. If
there is no room to the south of this room then this value is -1.
5. East room: This is the room number of the room immediately to the east of this room. If there is
no room to the east of this room then this value is -1.
6. West room: This is the room number of the room immediately to the west of this room. If there
is no room to the west of this room then this value is -1.
All 6 fields of information about each room are contained in order on a single line in the dungeon file.
Each field of information is separated by one or more spaces. The room described on the first line of the
file is the initial room where the player will start after the dungeon file is loaded. Here is an example
dungeon file which describes the rooms used above in the running example.
1 $This is an open field west of a white house, with a boarded front door.$ 2 -1 -1 -1
2 $North of House: You are facing the north side of a white house.$ -1 1 3 -1
3 $Behind House: You are behind the white house.$ -1 4 -1 2
4 $South of House: You are facing the south side of a white house.$ 3 -1 -1 -1
Notice that the second item on each line, the Description string, is delimited by the $ symbol. This
means that the Description string cannot contain any $ symbols.
Commands
Your program should accept the following commands.
1. loaddungeon: This command loads the information contained in a dungeon file. The command
takes one argument, the name of the dungeon file. This command should be the first command
issued by the player after starting the game.
2. north: This command moves the player into the room to the north of the current room. If there
is a room to the north then the description of the new room is printed. If there is no room to the
north then the message, “You can’t go there.” is printed to the screen.
3. south: This command moves the player into the room to the south of the current room. If there
is a room to the south then the description of the new room is printed. If there is no room to the
south then the message, “You can’t go there.” is printed to the screen.
4. east: This command moves the player into the room to the east of the current room. If there is a
room to the east then the description of the new room is printed. If there is no room to the east
then the message, “You can’t go there.” is printed to the screen.
5. west: This command moves the player into the room to the west of the current room. If there is
a room to the west then the description of the new room is printed. If there is no room to the
west then the message, “You can’t go there.” is printed to the screen.
6. quit: This command should end the program
Submission Instructions
There will be a dropbox on EEE which you will use to submit your code. You should submit a single C
source code file. The code must compile and execute on the openlab machines. The name of your C
source code file should be “Lab1.c”.
