Question

“Oh I know, let’s play Rock, Paper, Scissors, Lizard, Spock. It’s very simple.” What better way to expand the classic Rock, Paper, Scissors game than to add Lizard and Spock! Sheldon and Raj brought Sam Kass’s game to life on The Big Bang Theory in “The Lizard-Spock Expansion” episode.

 

Assignment & Discussion

Your task in Programming Assignment 8 is to create a C# console app-version of Rock, Paper, Scissors, Lizard, Spock (RPSLS). Use any of the programming tools and techniques you have collected throughout the term, even the previously banned arrays.

 

The RPSLS rules are very simple:

- Scissors cuts Paper

- Paper covers Rock

- Rock crushes Lizard

- Lizard poisons Spock

- Spock smashes Scissors

- Scissors decapitates Lizard

- Lizard eats Paper

- Paper disproves Spock

- Spock vaporizes Rock

- And, as it always has, Rock crushes Scissors

 

There are a number of ways you may choose to solve RPSLS, including:

- Sequential if/if-else along with &&(Conditional AND) statements

- Sequential if along with switch statements

- Two-dimensional array (Chapter 8)

 

Pseudo-randomly generate Sheldon’s choice andthe Gamer’s choice. No user (Gamer) manual input desired/required. Instantiate an object of the Random class and then generate Sheldon’s number and your (the Gamer’s) number using calls to the Next() method.

 

Implement your RPSLS so that the first person (Sheldon or Gamer) to reach three wins is victorious. Ties do not count for either player. I recommend a while loop as we do have to account for rounds that end in a tie. Note: generate new game choices (numbers) for each round of play.

 

For each round of play, write out each player’s choice, the applicable rule, who wins that round and the updated score. See Example Output below.

 

*** Do not slow down or pause the game play unnecessarily. ***

 

Recommendations

Consider an enumerated type (enum) to represent Rock, Paper, Scissors, Lizard and Spock. I believe you will find the enumeration constants more intuitive in your code than the underlying numerical values.

Pay close attention to sequence, selection and iteration to ensure your RPSLS game plays properly.  

Spend time pseudocoding how you want to solve this challenge. RPSLS is more complex than our previous assignments and may be significantly longer (in terms of lines of code). Take time to develop your algorithm. Don’t just hack it ‘til it works…
