My assignment guide
Topics: User Defined Functions and MATLAB Conditionals
A Childrens game studio needs you to write a MATLAB Program to allow two players to play the game Tic-Tac-Toe on a computer:
This is a two player (X's and O's) board game.
The game board is a 3 X 3 grid, where each location can hold either an 'X' an 'O' or a space (empty)
Note: we will linearize the grid and refer to the its locations as 1 - 9, for conveyance.
The players take turns placing their mark into one of the (empty) locations in the grid.
The game is won when a player has their mark in all three locations of any row, column, or diagonal.
The game can also reach a stalemate: neither player has won (by above criteria) however all there are no more empty locations in the grid.
Outline:
Create a MATLAB Script .m file
Establish variable(s) to represent the nine board locations
Create the game loop
i.Display the current state of the board – using separate displayBoard function
ii.Get a “valid” move location – note this can only be an empty location [1, 9]
iii.Modify the board variable(s)
iv.Check for a win and report it if so – game must end
v.Check for a stalemate – game must end
Create a MATLAB Function .m file
Establish its name (displayBoard), input(s) , and output (there really is not any)
Write the necessary MATLAB commands to display the Tic-Tac-Toe board, using the given input(s)
Make sure to test your script and function when they are done¸
Notes(s):
Keep track of the total number of moves, for an easy stalemate detection.
Your location choice user-validation loop must also not accept any location that is not currently empty.
At times things will feel very tedious - doing the "same" thing nine times ...
Sample Run(s):
