Setup for the Tutorial will give you a starting point to follow the tutorial.The tutorial is divided into several sections: You might find this tutorial and the guide complementary to each other. If you prefer learning concepts from the ground up, check out our step-by-step guide.

This tutorial is designed for people who prefer to learn by doing. The techniques you’ll learn in the tutorial are fundamental to building any React app, and mastering it will give you a deep understanding of React. You might be tempted to skip it because you’re not building games - but give it a chance. We will build a small game during this tutorial. This tutorial doesn’t assume any existing React knowledge. The new docs will soon replace this site, which will be archived. One for the game logic called Game.java, one called Computer.java for a simple computer player and a final TicTacToe.java where we will prompt the user for questions.The updated Tutorial teaches modern React and includes live examples. I’m going to let IntelliJ do all the hard work for me so just create a new project in the directory you want and call it TicTacToe. Once you have decided how to separate your concerns lets start programming! Since our game is super simple let’s let the user always go first and will always be X.

The game logic will be held in a different file as well. In Main.Java is were I will be prompting the questions but I will need to refer to a move done by a user and by a computer. You may want to separate your files differently so fell free to do so. Since Java is an object oriented language we need to think about our game in terms of OOP. Lets first decide how we want to get our project concerns separate. Follow the pictures and descriptions for each step and let’s start coding!

In the future blog post, we will talk about how to make it unbeatable using a minimax algorithm but for now we just need to make something show up on the screen and make sure we know when the game is won. This game will also feature a SUPER easy computer that just places pieces randomly. This version will be made with Java and I will be using the IntelliJ IDE.

We will be making a super simple Tic-Tac-Toe game! This 2 player pencil and paper game has very old origins and is ubiquitous across many cultures.
