Getting Started with Game Programming

According to a 2022 Statista survey, 70% of adults in the United States played video games on at least one platform. That means that if you’re reading this, chances are that you’ve played a game or two. But even with such a huge number of people playing video games, the number of people who know how to code a game is far smaller. 

In many ways, coding a new game can be just as fun as playing games, and it’s pretty easy to dive in. Maybe you want to eventually become a professional game developer for a studio. Or perhaps you just want to make a fun custom game for yourself or to share with your friends. Either way, it all begins with just a bit of code.

Coding Languages for Games


The Scratch coding language is an amazing place to start learning the process of making games! It has an easy-to-learn block-based interface that allows even beginning coders to quickly build code. While it is simple to pick up, it also has a surprising amount of depth to it that has led to some pretty amazing games on the platform.

One of Scratch’s best features is that you can easily see the code used to build all of the games hosted on its platform if you’re interested in how to make a game of your own


JavaScript is the coding language that helps support most of the interactivity that you can find on the web, which has made it a pretty popular language to learn. Its extremely flexible and lightweight nature makes it a great choice for building browser-based games that can be played on computers or mobile phones. Since mobile gaming is popular among such a large number of gamers, making a JavaScript game can be a great choice.


Python is best known for being a quick and easy coding language for automating small, repetitive tasks. It’s super fast for the tasks it’s good at, but it can have a hard time scaling for larger applications. That said, it is an excellent coding language for making smaller games, and even some larger games use Python as their main language.


C++ is the main coding language used in AAA games today (games produced by major publishers) and for a lot of good reasons. As a compiled language, it runs super fast and offers a ton of flexibility. It isn’t the easiest language to learn for complete beginners but is useful enough for game makers to be worth the effort. 

Another big benefit of C++ is that many of the most popular game engines can be used with it, including the well-known Unreal and Unity engines.

Introduction to Game Engines

While it is definitely possible to build a great game from the ground up, many modern games are incredibly complex. There’s a ton of code running in the background that a game creator most likely doesn’t want to program by hand. Instead, game creators will typically turn to a game engine to take care of the framework so they can focus on making a great game!

What are Game Engines?

Game engines are collections of code that need to be running in the background so that a game can run as it is supposed to. Many game engines include a variety of code libraries that creators can pull from so that they can create exactly the game that they want but with far less manual coding. 

Some of the things that a game engine might take care of include the code managing object collisions, sound effects, game physics, and more.  

Ultimately, if the game you want to make is more complex than you can reasonably code by hand, a game engine is the collection of tools that you’ll need to make it all possible.

Steps to Code a Game

So you’ve learned some code, you know about game engines, and you have a basic idea of the game you want to make. Now you want to know how to program a video game. 

Great! Let’s get started.

Making a game can be broken down into a series of steps that, if followed, will result in a game that can be played. All games, no matter how simple or complex, need to follow these basic steps. 

  1. Choose the type of game
  2. Add your game’s visuals
  3. Write the game logic
  4. Test the game
  5. Play the game with your friends!

1. Choose the type of game

The first step in programming a video game is choosing what kind of game you want to make. This includes thinking about how you want the player to interact with the game, the general theme of the game, and how the player will be able to win or lose the game.

2. Add your game’s visuals

The game’s visuals include everything that the player can see on the screen. That means the player’s character, any objects they might collide with, like enemies or coins, and the background setting.

3. Code the game logic

The game logic is the actual code that runs the game. Depending on how complex your game is, you may be able to code everything yourself, or you may need to use a game engine that pulls code in from larger code libraries. 

This is the step that many people think of as “programming a video game,” even though it is only one step of the process.

4. Test the game

The moment of truth! Testing the game to make sure everything works means pushing the game to its limits. Be sure to test every aspect of the game to make sure that everything works as intended. If something isn’t working right, it’s time to debug. Otherwise, the game is ready for primetime!

5. Play the game with your friends!

Success! You’ve finished the game! The final step is to release it into the wild and enjoy the fruits of your labor by playing your game with your friends. 

These five steps can be used to make all sorts of games, from the simplest Scratch game to a AAA shooter. 

Types of Games You Can Code

It’s important to remember that different types of games are made with different coding languages, but ultimately, no matter what type of game you want to code, or where you want to play them, the ability to code is what will get you there. 

So, just what types of games can you code? 

Web-based Games

Browser-based games are some of the easiest to code and access. Platforms like MIT’s Scratch allow even beginner coders to create and share fun games with minimal overhead. However, web-based games don’t pack a lot of power, which can be limiting.

Console Games

Console games are what most people think of when they hear the word “video game,” but they’re really only one of the types of game that you can code. Interestingly, even though consoles like the Xbox and Playstation are designed for the sole purpose of playing games, they’re only the third most popular place to play video games. 

Computer Games

Personal computers are incredibly powerful machines, and native computer games are capable of providing the absolute best game experience in terms of graphics and speed. If you want a game on the cutting edge of what’s possible, this is the type of game for you. But while computer games are the best-performing option, they’re only second-place in popularity.   

Mobile Games

Around 70% of Americans that play video games play them on a mobile device. That means that of all the types of games that you can code, mobile games have the greatest potential audience.

Coding Video Games

Now that you have a bit of an idea of how to program a video game, you might be wondering how coding video games actually works in real life, or perhaps even how you could become a video game designer or developer. 

The process of making a AAA game (the highest production value game) is typically the work of entire teams rather than something one person does on their own. That’s because the different parts of the process, from coming up with mechanics, to drawing the assets, to coding the actual game logic are all very distinct skill sets that people can specialize in. 

Working as part of a team allows everyone to focus on the parts of making a game that they know the best and results in a much better product.  

If you want to become a game developer, the best place to start is by figuring out which part of the process is the one you like best, and then work on learning everything you can about that particular role. Don’t know what part you’d want to do?

Start by coding a simple game on your own!
