How Video Games Are Coded? (Explained for Beginners!)

When you’re playing a video game, it’s easy to think that the programmers just created what they wanted and then pressed play.

But in reality, this is not how things work at all. There are many steps that go into coding a video game.

How video games are coded

How Video Games Are Coded?

The first step is finding an idea and then turning it into a prototype that you can test. Once the design document has been approved, programmers will start coding and testing the game to ensure it is playable. Once there are no problems, the video game can be published.

What Language Are Video Games Coded In?

Video game programmers will mainly use C, C++, Java, or Python. Each language has its own benefits and drawbacks that need to be considered when making a decision about which language to use for a project.


C is a low-level language that is used for system programming and software development.

It is efficient and easy to learn but can be difficult to read and write.


C++ is a powerful object-oriented language that has many features that are not found in other languages.

It is also efficient and easy to learn. However, it can be difficult to debug code written in C++.


Java is an object-oriented language that was designed for networked applications.

It is platform-independent, easy to learn, and has excellent documentation.

However, Java code can be slow when compared to code written in other languages.


Python is an interpreted language that is easy to learn and can be used for rapid prototyping. Its syntax resembles Java and C. It is known for its readability and comprehensibility.

What Steps Are Involved to Code a Video Game:

  • Finding an idea
  • Paper Prototyping
  • Prototype Testing
  • Design Document and Get Approved
  • Start Coding
  • Final Test
  • Publish

Finding a Unique Idea

The first step in coding a video game is to find an idea for the game.

This can be done by brainstorming and coming up with many different ideas or having someone else come up with one.

It’s important that you choose something new because if you’re just playing around, it will not be fun at all!

Paper Prototyping

Once you have an idea, it needs to be turned into a prototype.

This can be done with pen and paper or on the computer.

The point of this step is to start thinking about how your game will work in more detail than just what happens when people actually play the game.

Prototype Testing

Once there’s a prototype, it has to be tested by your friends and family.

They can give you feedback about what they liked, wanted to see more of, or just didn’t like at all.

Design Document and Get Approved

Once the prototype has been tested, it’s time to create a design document for your game.

This will outline everything that needs to happen in the video game and any challenges or difficulties that might arise from the game’s concept.

The design document needs to be approved by the person who came up with the idea for your video game before it goes any further because they are ultimately responsible for making sure that everything in this document is doable and realistic.

Start Coding

Once there’s a design document, you can start coding!

This means writing code that will make sure that the video game works properly.

There are many different languages and tools used to do this, but most of them depend on what type of video game you’re making.

Programmers start to add in all of the different programming elements.

This includes things like coding how objects interact with one another (for example, if someone is trying to get from point A to point B and there are steps they need to take along that journey), or changing what happens when a player does something certain in-game.

After adding elements a programmer can start to tweak and adjust the game as they go along.

If a player gets stuck on a level, for example, they may need to change something about it so that players can continue playing.

They’ll also be tweaking things like how quickly an object moves or whether or not players are allowed to finish off enemies just by walking through them.

Final Test

Once you have coded your video game, it needs to be tested again!

This time with experts who can give feedback about whether or not there are any problems with the game


Once there are no problems, it’s time to publish your video game!

This means uploading all of the files that you have created for your video game onto a website or app so people can play it.

What Does the Code for A Video Game Look Like?

The code for a video game (like all other programs) is written in a programming language.

The most popular languages are C++, Java, Python, and JavaScript.

Code Example:

If we want to move “Mario”. The code will look like this.

  1. While(playing) 
  2. if(keyDown()) 
  3. dir = getDirection(); // dir will be -1 or 1 
  5. mario.x += velocity * dir; // mario will move to left or right depends on the dir value 
  7. display (mario) // will display mario in the appropriate x position.

What Language Are Video Games Coded In?

Video games are coded in many different languages. Some of the most popular ones include C++, Java, and Python.

Since every language has different features, a developer may choose one that best suits their needs.

For example, C++ is popular because it gives the programmer control over how memory and resources are handled, while Java offers strong security by default.

Python’s versatility with other programs makes it an attractive choice for many developers too.

Which Software Is Used for Creating Games?

To create video games, you need a software program that can handle all the necessary coding.

There are many different programs to choose from, but the two main ones used in game development are Unity and Game Maker Studio.

Why Use Unity for Game Development?

Cross-platform development

Unity is a cross-platform tool that can be used to develop games for multiple platforms.

This means you can create one game and then publish it on PC, Mac, iOS, or Android.

For example, if an indie developer wanted to make a game with the intent of publishing it on mobile devices, they could use Unity as their development tool and then publish it on iOS or Android.

The Unity Asset Store

The unity asset store sells a huge variety of assets that can be used to create the game world, including models, textures, environments, and more.

This means indie developers are able to spend less time creating basic art assets for their games, saving them both time and money.

Unity Is Free

Unity doesn’t charge for the software to be downloaded.

This means that it has a lower barrier of entry, and indie developers can get started with game development more quickly without having to spend any money upfront on licenses or subscriptions.


Unity is made up of modules.

This means that you can pick and choose which parts of the engine to use for your game depending on what it needs, such as whether or not a game requires physics simulation.

Modular software allows indie developers to spend less time worrying about how every part of their games will interact with one another and more time focusing on their game design.

User Friendly

Unity is written in C++, but it has a simple user interface that makes coding easy to learn for beginners.

Unity isn’t just for indie developers, though; large companies like Disney use the software too!

For example, they used Unity to create “The Jungle Book” movie.

Unity Allows for Rapid Prototyping

One of the most popular uses for Unity is as a game engine to create prototypes quickly and iterate on designs.

This means that you can come up with an idea, make it into a prototype in under five minutes and then get feedback from your team or family members without having to spend a lot of time.

Why Use Game Maker Studio for Game Development?

Game Maker Studio is easy to use drag and drop game engine, which means that anyone can create a working prototype of their ideas in minutes.

It has a large library of prebuilt assets, including models, textures, and sound effects available for purchase from the GMS store or through third parties like Open Game Art.

You can publish Game Maker games to multiple platforms, including Windows, Mac, and Linux.

It has a large library of prebuilt assets, including models, textures, and sound effects available for purchase from the GMS store or through third parties like Open Game Art.

It has a free version that allows you to export your game for play on Android or iOS devices in order to get feedback without having to spend money upfront.

You can use the built-in scripting language GML (similar but more powerful than JavaScript) to make games without having to learn any other programming languages.

It has a large library of prebuilt assets, including models, textures, and sound effects available for purchase from the GMS store or through third parties like Open Game Art.

It is free and doesn’t require a subscription or license fee in order to download the software.

It has an intuitive user interface which makes it easy for beginners as well as people with traditional development backgrounds to pick up quickly.

There are also many tutorials available online that teach you how to use the software as well.

There is a large community of people who can help with making your game through forums, chat groups, or even just by commenting on games posted in the open Game Jams section of their website.

It uses cel-shaded graphics, which means that it will look good on mobile devices as well.

You can export your game code into an executable file for the end-user to download and play on their desktop computer without having to worry about any of the technical details that might be required by other development platforms.

It has a built-in marketplace where you can sell or share games with others while also being able to track how many downloads they have.

You can also create and sell your own games on the marketplace as well or use it for free in order to find others who are making similar games that you could collaborate with them on instead of competing against each other.

It has a built-in map editor, which means that you can create a fully functional video game without even having to write any code at all.

It has its own scripting language called GML, which is easy to learn and has many tutorials available for it online.

It also allows you to export games in order to work with multiple platforms, including Linux, Mac OS, and Windows computers, as well as tablets or mobile devices like Android phones or iPhones.

You can use Game Maker’s built-in map editor without having to write any code at all.

It is easy to use and doesn’t require knowledge of a programming language, so it’s perfect for beginners or people with traditional development backgrounds who want an easier learning curve.
