💻 PROJECT #3.1: Adventure

Overview & Setup

One of the first games coded for early computers in the 1970s was called Colossal Cave Adventure. It was a text-based interactive fiction game where you had to make your way through an elaborate cave. The program only understood one word or phrase commands like north, south, enter, take, etc.

You can try playing adventure recreated online following some of the commands in this walkthrough. Part of the challenge is finding the commands that the code will understand.

In a game like Adventure, if, else if, and else statements can be used to respond to commands from the user like n, s, e, w.

  1. Go to the CS2 Project 3.1 assignment on Blackbaud and follow the provided GitHub Classroom link.

    📁 Clicking the link generates a private repository for your project with the appropriate starter code. Note that projects are stored within the BWL-CS Organization, so you cannot access it from the “Your Repositories” page!

  2. Open the repository in a Codespace whenever you spend time working on the program, in class or at home.

    ⚠️ Always remember to commit changes after every coding session!

  3. When your project is complete, submit the link to your repository page (not the Codespace!) in the CS2 Project 3.1 assignment on Blackbaud.

Instructions & Requirements

Copy in the starter code below and run the program. This is a very simple adventure game that lets the user move in 4 different directions. Right now, it only lets the user move north.

import java.util.Scanner;
public class Main {
  public static void main(String[] args) {
    Scanner scan = new Scanner(System.in);

    // SCENARIO #1
    System.out.println("\n\n You are on an island surrounded by water.\n There is a path to the woods to the NORTH, the sea to the SOUTH, and a beach shack to the EAST. \n Which way do you want to go (n,e,s,w)?");
    String command = scan.nextLine();
    if (command.equals("n")) {
        System.out.println("You enter the forest and hear some rustling. \nThere may be tigers here or maybe it's just monkeys.");
    }
    // Add else-ifs for s, e, w, and an else for any other input. Be creative!
    
  }
}
  1. Add in else if statements to go in the directions of "s" for south, "e" for east, "w" for west, and an else statement that says “You can’t go in that direction”. Be creative and come up with different situations in each direction!
  2. How many test-cases are needed to test all branches of your code at this point? 💬 Write your answer in a //comment, and try out your test-cases.
  3. Next, come up with a unique location for your adventure and replace the deserted island theme with scenarios for your location.
    • Your adventure could be set anywhere – a place you are familiar with (like BWL or Manhattan), a place you’d like to visit, or even a fantasy/fictional world.
    • 📝 PLAN & DRAW OUT YOUR MAP on paper before coding!!!
  4. Expand the gameplay by adding more branches (nesting conditional blocks).
    • You do not need to keep the commands as n, s, e, w every time. Just make sure you tell the user what the options are!
    • Don’t forget to take input (scan.nextLine()) for the user’s command before your next conditional block.
    • Follow your map (or flowchart) as you write code for the paths you designed.

Extension

Turn your text-based adventure into a visual one with a GUI (Graphical User Interface)! See my Java Swing demo: GitHub Swing GUI
