Description

Assignment Submissions

This project will be submitted in two parts. Both parts of the assessment are equally important for the successful completion of your project, so it is essential that you understand the requirements of both parts before you start.

• Assignment 2 :: Mastermind (Part A: Project Plan)

Marks: This assignment will be marked out of 30 points.

Weighting: 15% of your final mark for the unit.

This assignment is the first part of a larger project, which you will complete in Assignment

3. This task consists of your project planning documentation. It will include details of the requirements & analysis of your program, including UML Class diagrams.

The purpose of this assignment is to get you comfortable with planning a C++ programming project for Assignment 3. The task is detailed later in this assignment specification, as are the specific marks allocation.

• Assignment 3 :: Mastermind (Part B: C++ Project Implementation)

Due Date: TBA (Week 12)

Marks: This assignment will be marked out of 100 points.

Weighting: 25% of your final mark for the unit.

This assignment consists of your implementation of your project, as outlined in your Project Planning document (Assignment 2).

Your project must follow your project plan and must be submitted as a Visual Studio project, including all header and cpp files, and any appropriate text files to ensure the program compiles and runs.

This assignment consists of one Application file and associated custom Class files. The purpose of this assignment is to get you comfortable with designing and implementing basic multi-class C++ programs. The task is detailed later in this assignment specification, as are the specific marks allocation.

NOTE! Your submitted files must be correctly identified and submitted (as described above). Any submission that does not comply will receive and automatic 10% penalty (applied after marking).

NOTE! Your submitted program MUST compile and run. Any submission that does not compile will automatically be awarded a ZERO. This means it is your responsibility to continually compile and test your code as you build it.

Assignments 2 and 3 – Mastermind

Assignment 2: Master Mind (Part A)

You are to implement a computer-based variant of the board game Master Mind. This is a two-player deduction game played with a specialised game board in which the aim of the game is to break the hidden code in the fewest number of moves.

You can watch a video on how to play here: https://www.youtube.com/watch?v=ZSXpmIH-_d4 or

read this article: https://www.wikihow.com/Play-Mastermind or even play an online version here:

http://www.webgamesonline.com/mastermind/.

In your version, you will be the code breaker, playing against the computer who is the code maker.

For Part A of the assignment you will focus on the planning of the project. In Part B you will focus on creating the various interactive objects in the game and program the player interactions.

Basic Game Play

First, the code maker selects any 4 coloured pegs (from 8 different colours) in any combination to create the hidden code.

The code breaker now attempts to determine the hidden code by selecting 4 coloured pegs at a time, and placing them in the order they think matches the hidden code.

After each guess, the code maker gives clues – a black peg for the correct colour in the correct position, a white peg for the correct colour but in the wrong position, leaving empty slots if the colours are not in the code.

The code breaker must guess the code in 10 turns or less, otherwise they lose the game.

In your version you can use words, letters, numbers or symbols for the code.

Human Player:

You, as the human player, must be able to input your choices for the hidden code as required by the program. For example: if the program uses numbers for the code then you must enter 4 numbers as your guess. After you enter your guess, the board will update, showing you the accuracy of your guess. You continue until you have cracked the code (you win) or you have run out of turns (you lose).

Computer Player:

Obviously, you as a player can make strategic choices as to which colours to use when guessing the hidden code. However, programming the computer breaking the code is beyond the scope of this assignment. Therefore, the computer will be assigned the role of code maker and the player will be the code breaker (see Assignment 3 brief for more details on this).

Project Plan

Having a clear plan for your project before you begin coding is essential for finishing a successful project on time and with minimal stress. So part of this assignment is defining what will be in your project and what you need to do to actually develop it.

Important: You must also read the requirements for Assignment 3 in order to be able to complete the documentation required for Assignment 2.

The documentation you must submit will include the following:

• A description of “How to Play”

This will be the information you display on the opening screen of your game to inform the player what they need to do in order to play and win the game. Do not just copy the game play description above, make your own description.

Note: This description must be saved as a text file and read into your game when the program begins. You can also use this as a convenient way to display “help” if the player asks for it.

• A development outline of your game

Using a simple outline format (numbered or bullet points) state the main actions that the program will have and then, as sub-points, state the things you will need to do to make that happen.

The outline structure should contain all the elements of your game, as this is a high level description of your approach to the development of your program. You should include at least the following headings and provide examples of happens under each section.

• • The game setup (everything that happens before the game starts)

  • The player’s turn (the sequence of events that happen during a turn)

  • Processing player input (include each of the commands your player can use)

  • Providing feedback to the player (in response to the player’s interactions)

  • The end game conditions (include all win and lose conditions)

  • Additional Features included, if any – see Assignment 3

  • Outline the functionality of all your game classes – see Assignment 3

Here is an example to get you started with your project outline:

15. The Game Setup

    • Display an overview of the game rule so the player knows what to do to win.

      • read this information from a text file

    • Initialise the game elements:

      • add the player – ask for the player’s name, set default variables

      • all the other things that will happen during initialisation including

15. • • • creating the game board

15. • • • initialising other game variables (list them here)

As you can see, you only have to describe the actions the program will take, not the code, for the outline. The idea here is to give you a starting point for when you start writing your code as you can use this as a checklist of the things you need to include.

Assignment 3: Master Mind (Part B)

You are to implement the Master Mind game you started in Assignment 2 by creating a Visual Studio Project using your project plan as described in your previous submission.

Your completed Master Mind game must demonstrate the following:

• You MUST implement your program using the following classes, as a minimum, you may include more (as appropriate for your game design):

• • Player class: holds a player’s details including their name, score, wins and the number of games played.

• • Board class: holds the current game’s details including each of the player’s previous moves and associated clues, the number of rows and columns used in the game.

• • Application file: holds the main() function and controls the overall flow of the game.

You may include other relevant attributes and behaviours to these classes, as identified in your project plan.

• The Player must be able to do the following:

• • assign a name which is requested at the start of the game and used in the feedback given

• • see all their previous moves at the start of their turn so they can make an informed choice

• • type in a code, using either letters or numbers and seeing appropriate feedback on the accuracy of their input

  • continue typing in codes and seeing feedback until they either “crack the code” or run out of turns

  • quit the game at any time – during or after a game

• The Board in the game should have the following characteristics:

• • a defined number of columns (code slots) and rows (the maximum turns a player has)

  • be able to display each code entered and given feedback as a specific row

  • be able to reset the board to empty at the end of a game

  • not be able to add any more rows beyond the specified number

• The Game Application must do the following:

• • display the “how to play” information at the start of the game

Foundations of C++

Assignments 2 and 3 – Mastermind

• create or select a secret code – using words/letters, symbols and/or numbers

• display an appropriate and uncluttered user interface providing relevant information to the player at all times

• ask for and allow the player enter a code

• compare the player’s code to the secret code and provide appropriate feedback to the player (a symbol for a correct letter/number in the correct position and a different symbol for a correct letter/number but in the wrong position, it is optional to use another symbol if the letter/number is not in the code)

• display the updated game board after each code entered by the player

• terminate the game (player wins) when the player has guessed the code

• terminate the game (player loses) when the player has run out of turns

• provide player stats at the end of the game (wins, loses and score)

• the player should be able to QUIT the game at any time

Program Reflection

You must also provide a 300-word written reflection of your object-oriented design and how well you believe it was to implement. You should cover the following areas:

• Discuss why you designed it the way you did.

  • Why did you create your classes that way?

  • How does this reflect an OO design or approach?

• Discuss how well you were able to code it

  • Highlight any issues you found once you tried to implement your design.

  • How did you resolve these issues?

• If you were to do this project again, discuss how you might change your design to make your solution easier to implement, more efficient, or better for code reuse.

This must be a Word or PDF document which must be included in the same folder as your *.sln file. Your document file MUST be named as follows:

“A3-YourFistNameLastName.docx” or “A3-YourFistNameLastName.pdf”.

Extra Functionality

The marking criteria indicates that you should make some individual additions to this in order to achieve the final 20% of the mark.

Following is a list of additional features you can include, with the maximum number of marks [x] you can earn for each one. You may implement one or more features from the list, but you will only score up to the maximum of 20% of the total assignment marks or 20 marks.

You should aim to add some additional creative elements to the gameplay, as well as advanced object-oriented design elements or advanced use of pointers.

• Add a theme to the game which is incorporated into the game play through the story and the feedback given (for example: Word Detective, Number Cruncher, etc.) [2]

• The player can select a skill level (eg: Novice, Thinker and Master Mind) which modifies the game parameters – the number of elements in the code and the number of rows (turns) the player has to solve it. For example: easy has 4 elements out of 6 with 10 rows, tricky has 5 elements out of 8 with 12 rows and hard has 6 elements out of 10 with 14 rows. [2]

• Implement an appropriate scoring system based on the game parameters – number of turns taken, a bonus for unused rows, +/- point based on a win or a loss, etc. [3]

Foundations of C++

Assignments 2 and 3 – Mastermind

• Read in word and/or element lists from a file (based on word length, such as 4-, 5- and 6-letter words, numbers or symbols) and store appropriately. Word lists should have at least 20+ words of each length. The list used in the game could be linked to a player skill level and/or randomly selected at the start of each game. [3]

• Give the player additional options apart from just typing the code or quitting the game. This could include options to: ask for help (displays an information screen loaded from a file), ask for a hint (displays a random element from the secret code and must be a limited option), ask to resign from the current game but not quit the entire game (ends the current game as if the player ran out of turns and displays the secret code). [4]

• Display the board using ASCII art. [4]

• Allow the game to be saved and restored at the player’s request. [4]

• Allow the player to select what elements will be used in the code (numbers, symbols, letters, words). Words should range from 4- to 6-letter words, while a specific range of numbers or set of letters/symbols should be clearly identified and displayed to the player. The feedback symbols can remain the same. [5]

• Ask the player if they want to be promoted to the next skill level after winning 5 games. If they accept their skill level is increased by one (to the maximum level permitted in your game). Also, if the player loses 5 games in a row they are automatically demoted one skill level (to the minimum level permitted in your game). [5]

• Implement a more sophisticated computer player. The computer player should be able to have its own Player object (including name and any other player stats as required for your game), and score the points the human player would lose plus earn a suitable bonus for the win. It should also make intelligent choices for words/letters, symbols or numbers including using doubles or triples of the same letter/symbol/number. It should also have the ability to give random comments to the player based on how well (or not) the player is doing. [10]

You certainly do not have to implement all of the above to earn marks for extra functionality. Just remember the maximum number of marks you can earn are given in [x]. It is up to you!
