Creating A Python Tic-Tac-Toe Game Using Pygame
Hello guys, welcome back to the Pygame Series, today we are going to build another simple but cool game. Today I am going to show you how you can build a Python. But, moving far let me give you the definition of the Tic Tac Toe Game.
Definition of Tic Tac Toe Game: It is a traditional strategy game where two players look for different turns to complete a row, a column, or a diagonal with either three O’s or three X’s drawn in the spaces of a grid of nine squares. The squares contain different noughts and crosses. It is typically a paper-and-pencil game but now programmed like a computer game. The player whoever first completes placing three of their marks in a horizontal, vertical, or diagonal row in a square wins.
Now, as we have completed the first step. Let us move on directly on how to create a Python Tic Tac Toe Game using Pygame.
Requirements for the Game:
- A good & fast processing PC with a Python environment & pygame package installed. You can choose Mac Book, Asus Zenbook, Dell Inspiron, or any Pc with a high processor.
- Code Ide or Code Editor.
- A notebook for writing important notation.
- Your Focus.
Working of our Pygame:
Our Tic Tac Toe is programmed in other to allow two users or players to play the game in the same time. It’s GUI game & gives an instant alert when players wins or losses or draw the game.
Steps to build a Tic Tac Toe Game:
- First of all, create a folder named any in your PC & drag it to your code editor.
- Secondly, open your command prompt(CMD) & install the Pygame package by typing Pip install Pygame command.
- Thirdly, make a file called main.py & folders called image. It will you to store all your codes & image resource files needed for the game.
- Set your codes which are given below to your respective files. You can download the image file this is given in the button link.
- Lastly, run your Pygame by typing Python main.py in your Command. That’s it you have your game.
