This project requires you to implement a text adventure game using the C programming language. A text adventure game is a form of interactive fiction in which players use text commands to control characters, influence the environment, and navigate a virtual world. The first text adventure game developed between 1975-1977 was called Colossal Cave Adventure. If you have never played a text adventure game you should give it a try to get the idea. The goal of this lab is to practice various aspects of the C programming language to help you prepare for implementing a text adventure of your own.
At the heart of a text adventure game is the state of the world that you interact with. This can include players, rooms, items or objects, and anything else that one could imagine simulating in a virtual environment. The virtual world consists of a set of "rooms" that are linked together to form locations that can be navigated through directions such as north, south, east, west, up and down. A room has a description as well as objects that can be taken by a player, or more typically referred to as an avatar, controlled by the user of the game. An avatar can be a character that is controlled by a user or it can be a non-player character. You could also extend the notion of a player to one that is controlled by an Al. An avatar can also have an inventory (e.g., backpack) that can hold items collected as they navigate from room to room. Items can and should be used to change the state of a room (i.e., unlock a secret room or win the game).
A text adventure is played by placing a player's avatar in a starting room or location and allowing the user to provide text input. To get an idea of how this works you can check out many example plays of the adventure game online. In general, there are several actions that can be played in a particular location including navigation such as "look" to provide a description of the location the player is currently in or go west to navigate to a new location (if you are able to go that direction). You can also pick up objects such as "take key", apply an object in a location with use key", or get rid of an object with drop key". The objective of a text adventure game is up to the designer of that game. It could be to successfully navigate out of a maze of twisty passages or find a hidden item in a location and deliver it to a final location. The possibilities are endless, however, these games often involve a puzzle the player must solve and very often contain an easter egg to make it more interesting.
Your primary objective is to use the C programming language to design and implement a functional text adventure game as described in the previous section. You are required to design and implement the appropriate data structures and corresponding algorithms that will enable a human player navigate their avatar through a virtual world and solve a puzzle that you design. The general design of the game is up to you, however, you must satisfy the following requirements:
Game Requirement
1. Your game must have at least 8 rooms.
2. Your game must allow rooms to contain items.
3. Your game must implement an avatar where the avatar has an inventory (a place to put items).
4. Your game must allow an avatar to "see" the room they are in with the command look.
5. Your game must allow an avatar to move through each room using the command "go DIRECTION" where DIRECTION is a direction: north, south, east, west, up, down.
6. Your game must allow an avatar to pick up items with the command "take ITEM" where ITEM is the name of an item in a room.
7. Your game must allow an avatar to use an item with the command "use ITEM" where ITEM is the name of an item in the avatars inventory. The effect of using an item depends on the room the avatar is in.
8. You must implement at least one instance where an item alters the state of a room that the avatar is in.
9. Your game must allow an avatar to drop an item with the command "drop ITEM" where ITEM is the name of an item in the avatars inventory.
10. Your game must have a winning state (allowing the game to end).
1. You must use C structs in your code to represent various game objects.
2. You must use pointers in your code.
3. You must use dynamic allocation in your code using malloc/calloc.
4. You must deallocate memory in your code using free.
You are encouraged to be as creative as you would like with this game. Your virtual world can be anything ranging from fantasy and sci-fi to places on the UMass campus, home, or vacation. Your virtual world can be inside a building or outside, the possibilities are endless, but it is up to you to come up with the world. You are also welcome to introduce additional commands that allow your avatar to interact with the virtual world in various ways.
You should organize your code into multiple C files. In particular, you are to have the following files:
