Rock Paper Scissors Project

Overview:

In this unit, coders will create a Rock, Paper, Scissors game. To create this project, coders will use JavaScript to take user input, use the Math Library to pick a random computer choice, and use conditionals to determine the winner.

Day 1

Planning

Set-Up

JavaScript

  • Use JavaScript to display the value of the input on the page

HTML and CSS

  • Add any more HTML elements you will need to the page
  • Customize your HTML with CSS

Wrap

  • Save and submit your website using the link on the session agenda.

Day 2

Javascript

  • Outside of your click handler, declare the variables you'll need to track the user choice, computer choice and winner and assign them values of empty strings.
  • Outside of your click handler, declare a randomNumber variable and set it equal to 0
  • When the user initiates the game, generate a random number and assign it to the randomNumber variable.
  • When the user initiates the game, store the user choice.
  • When the user initiates the game, display user choice to the screen.

Wrap

  • Save and submit your website using the link on the session agenda.

Day 3

JavaScript

  • Write a conditional statement which, given the number range of randomNumber, assigns ‘rock’, ‘paper’ or ‘scissors’ to the variable that holds the computer choice.
  • Display the computer choice to the screen.
  • Write conditional statements that compare the user choice to the computer choice to determine the winner of the game.
  • Display the winner to the screen.
  • Clear the input value once a result is displayed.

Wrap

  • Save and submit your website using the link on the session agenda.

Projects Extensions:

  • Style your page to fit the developer's personality
  • Validate the input so that it will return “Not valid input” if the user types in a wrong choice.
  • Accept any form of a word regardless of capitalization (i.e. “Rock” “rock” roCk”)
  • Keep track of total wins and losses, until the page refreshes.
  • Allow for more variety in throwing options. Example: Rock-Paper-Scissors-Lizard-Spock
