Tic Tac Toe

We're gonna continue on our `Tic Tac Toe` game developed from last semester. This is a two-player game where each player takes turns to mark a square on a 3x3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game.

This time, we're gonna make some adjustments so that human players can play against the computer.

Code Refactor

Code refactoring is the process of restructuring existing code without changing its external behavior or functionality. It improves the internal structure, readability, and maintainability of the code, making it easier to understand, debug, and extend in the future.

Common Refactoring Techniques

• Extract Method: Pulling out a piece of code from a long function into its own method to reduce complexity and improve readability.
• Rename Variables: Giving variables meaningful names to improve clarity.
• Remove Duplicate Code: Eliminating redundant code by creating reusable functions or classes.
• Separation of Concerns: Use python modules to separate different functionalities into distinct files, making the codebase more organized and manageable.

Task

We're going separate the starter code run.py into multiple files:

• game_logic.py: Contains the game logic functions like check_win and check_tie.
• colors.py: Contains the color constants used in the game.
• drawings.py: Contains the drawing functions like redraw and button_rect.
• main.pyThe remaining code after moving functionsout. It contains the main running loop of the code

Here's what your main.py should look like after refactoring:

• main.py

Please finish the rest of files

Player vs. Computer

To make the game more interesting, we're gonna add a computer player that can play against the human player. The computer player will make its move based on a simple algorithm that you will implement.

Computer Strategies

We've disucssed several strategies that the computer can use to make its move:

• - First Available Move
  The computer makes a move on the first empty location on the board.
• - Random Move
  The computer makes a random move on the board.
• - Center Move
  The computer makes a move to occupy the center of the board.
• - Corner Move
  The computer makes a move to occupy a corner of the board.
• - Edge Move
  The computer makes a move to occupy an edge of the board.
• - Winning Move
  The computer makes a move that will lead to a win.
• - Blocking Move
  The computer makes a move to block the opponent from winning.

We have no class next week. Have a good Holiday!!

End of Year Assignment

Dec. 15, 2024

No class next two weeks, we'll resume on Jan. 4th, 2025

We've talked about game menu screen this weekend. Basically, your game should have two views

• Menu Mode
• Game Mode

Menu Mode allows user to select among the three levels, namely Easy, Hard and Pro

Game Mode is where the game is played. The computer player will make its move based on the selected level.

Homework

Try to complete the game on your own during the break.

We'll discuss the solution on Jan. 4th, 2025.

Here's a demo of a finished game

Class Meet 01/04/2025

We've compleleted the following on class:

• menu view button click
• navigation logic of two game views
• clicking on a level shows Game Board view
• clicking on Start Over shows Menu view

Please find out the lastest src code here Homework

• Implement three strategies for computer move, namely, easy, hard and pro,
• Determine the computer strategy based on the user-selected level
