I propose to introduce Python classes to implement the Game Loop pattern. Using these tools, I show how to refactor the code in the previous post to get a more robust and readable program.

Thanks to the Pygame library we installed in the previous post, we can draw 2D graphics. In this post, I propose to introduce controls with the keyboard as well as some improvements like window centering and frame rate handling.

In the previous posts, I introduced enough of Python and patterns to start creating games with graphics using the Pygame library.

Pygame is a popular library for creating 2D games. Like the random library we used before, the …

The time has come to see our first design pattern: the Game Loop Pattern! This pattern can give us many good ideas to refactor our game in a very effective way.

It is now time to organize/refactor our code! When you begin, this is a strange process since the final code does the same as before. However, refactoring is the only way to create a code easy to maintain and expand.

In the previous post, the magic number is always the same. I propose now to introduce random numbers to change the magic number every time we launch the game. I also present imports and more on integers.

In previous posts, I only used strings and booleans. In this one, I use a new data type called “int” (for integer) that allows the storage and computation of natural numbers (numbers without a decimal part). I use them to create the famous “guess the number” game!

The previous game only allows one try: you have to restart it to propose another word. In this post, I introduce loops, and I use them to repeat the game until the player finds the magic word.

Programs in the previous post always lead to the same result. Here, I show you the basics of branching, or how to change the flow of a program depending on cases.

If we want to display a message when the player types a specific word, we can use the following syntax:

word = input("Enter t…

In the first post, we saw how to install an IDE and how to display a message; it is time to add some interaction with the player.

Create a new python program and type the following line:

input("Press Enter to continue...")

If you run the program, you get the fol…
