Tic-Tac-Toe Project

Overview:

In this unit, coders will create the classic game of tic tac toe in their browser! The user will input moves as player X or O on a tic tac toe board. When a player wins, the game will end and a message will display the winner.

Day 1

Planning

• Complete the project planning document.

Set-Up

• Go to the repository
• Fork this repository to your github account and import into a new Glitch project
• Make your site live on gh-pages
• Submit your website using the link on the Agenda

JavaScript

• Declare a variable that keeps track of the current player and set it equal to either a string of "X" or "O"
• Declare a variable that keeps track of the total number of turns taken and set it equal to 0
• Declare a variable of a boolean type that will signal whether or not the game has ended and set it equal to false
• Declare a function called with two parameters that removes the button of the corresponding ID, and changes the text of the div that is the tileId to the player variable.
• Declare a function with 0 parameters that will change the current player to either "X" or "O" depending on the current player. Decide where to call this function.

Wrap

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

Day 2

JavaScript

• Declare a function with 3 parameters of the tileIds, and return if the value of the each of the tileIds are equal to the current player. This function will check if the player has won.
• Declare a function that will call the function above on all of the vertical combinations of tiles.
• Declare a function that will call the function above on all of the horizontal combinations of tiles
• Declare a function checkDiagonalWins that will call the function above on all of the diagonal combinations

Day 3

JavaScript

• Implement behavior that will change the title to "It's a draw!" and end the game by changing the boolean variable to true after 9 pieces are placed. Do this by writing a function that will add 1 to the current turns, and check if that counter has reached 9.
• In each of the win functions, if the win condition is satisfied, set the end game variable to true, and change the title to "[Player] Wins!"
• Update your functions to check if the game has ended first before placing a piece.
• Determine the appropriate location to place the Win functions

Wrap

• Push your changes!

Project Extensions:

• Add in your own css to personalize your project
• Create a button that will reset the game back to the original (this requires clearing the Xs and Os, and putting the "move" buttons back)
• Keep track of the score between the two players: X wins, O wins, and draws
• Change the 9 button functions to instead be one generic function on the button selector
• Change the board to be 4x4 and end the game when there is a 4 in a row
