How to Code a Game for Beginners 2023: 5 Easy Steps to Get You Started

Game developers are among the highest earners in the software engineering industry and there is an ever-growing demand for these experts. If you want to learn how to code a game in 2023, this piece is for you. It doesn’t matter if you are a seasoned coder or not. It covers how to code a game for beginners. 

You will learn the core concepts of game development, the differences between game development and design, and the programming languages required for game development. You will also get a preview of some of the best online coding courses for gaming and excellent gaming ideas you can try. 

What Is Game Development?

Game development is the creation of digital games. This covers the entire production cycle from writing the code to launching the final product. According to some, the game development process extends from the conception of a gaming idea to the marketing phase. 

Some developers have all the design and coding skills required to handle every aspect of game development. Other programmers may simply specialize in one aspect of game development and collaborate with others to build the perfect game. 

Video Game Design vs Video Game Development

Video game design is the process of adding aesthetics and interactivity to the user-centered part of a game. On the other hand, game development involves bringing the game to life with lines of code. Game designers are creative types, whereas game developers are more logical. 

Apart from aesthetics, game designers also focus on the storyline, characters, reward systems, and the entertainment or educational value of a game. It deals primarily with the conceptualization of a gaming idea. The game developer then takes that concept and makes it a reality. 

Programming Languages Used by Video Game Developers and Video Game Designers

The most popular programming languages used by game developers and designers are C++, C#, Java, and CSS. Other common options are HTML5, JavaScript, and SQL. C++ is arguably the best choice because it is an object oriented programming language. 

Game developers who learn how to use C++ can create reusable blocks of code and thus exercise more control over the graphical aspect of game development. Similar to C++ is Java, which is a dynamic programming language that game developers like because it supports multithreading and sockets. It is easy to learn if you already know C++. 

C# is another favorite of game developers because one of the most efficient game development resources, Microsoft’s XNA network, is written in C#. One of the best ways to master this language is by attending one of the many reputable C# coding bootcamps out there.

Cascading Style Sheets, popularly known as CSS, is vital for the user interface of a game. It is used to describe the presentation of HTML and XML documents. Game developers can combine CSS3 with JavaScript to create an interactive game.

You must learn one or all these programming languages if you want to code a video game. 


How to Code a Game for Beginners: 5 Easy Steps to Follow

You can learn how to code a video game in just a few steps. However, if you’ve yet to master any of the programming languages listed above, you need to do that before you proceed to the stages below.

1. Conceptualization 

This is the first level of game development, so to speak, and it involves coming up with a game idea, storyline, gameplay, and design. You can’t dive into development without a clear vision for the end product. If you plan to commercialize your game, make sure you research thoroughly and come up with a concept that will sell. 

2. Choose a Game Engine 

A game engine is a program that lays out the software framework required for designing and developing a game. The game engine creates animation, sound effects, graphics, and an array of other features for your game. It is like a visual studio for game development.

The most popular game engines used by video game developers are Unity 3D, Amazon Lumberyard, Game Maker, and Godot. 

3. Create Your Game Design Document 

A game design document is a detailed list and outline of your game. It serves as a guide that sees you through aspects of the game design process. It should contain details about your plans after development as well. Do you have plans to market the game? Do you intend to update it intermittently?

A design document is especially important if you intend to seek out funding for your game. A prospective investor will know you mean business if you have a clear outline of what you want to make and how you intend to make it. 

4. Write the Program for Your Game 

This is where your coding skills come in handy. Start writing your program on the game engine you choose for the project. With the right game engine, even the most complex games can be designed without glitches. Professional developers may be able to build simple games without game engines, but beginner coders are encouraged to use one. 

5. Test, Beta Test, and Launch

After you finish coding, test your game to see if it is working or if it has any glitches. If you’re working with a team, your team members should also test the video game. After that, move on to beta testing. Beta testing involves inviting people in your target demographic to test your game and provide feedback.

Beta testing can either be closed or open. With closed beta testing, only those you invite privately can participate. With open beta testing, the game will be available to members of the public. In any case, beta testers provide valuable feedback about the sound effects and other features of the game so that it can be edited ahead of the final launch. 

Now you’re ready to launch the complete game for public consumption. If it’s a mobile game, reach out to application stores for permission to publish it. As long as it meets the eligibility requirements set by the app store, you can publish it.
