If you’ve ever wanted to create a video game, you may know that you need to learn to be a coder to accomplish this. For some people, they see coding as this impossible challenge in a similar vein to all of computer science, barring their way into the game development industry and becoming a coder. Here in our modern times though, learning to code has never been more accessible!
However, trying to become a coder can definitely be a bit of a challenge if you’ve never touched a single piece of code in your life. So, how to learn coding is definitely not an intuitive process. With many different programming languages and game engines available, though, there are fortunately countless online learning resources and tutorials to help you on your coding journey.
In this guide, we will help you take those crucial first steps on how to learn coding, so that you can more quickly spread your wings and start working on those dream projects you’ve had in the back of your head. If you’re ready to get started and learn how to code, let’s jump in!
What is Coding?
At its core, coding is a human writing down instructions for a computer to run (execute). That’s all code really is – instructions a computer programmer creates. Things like: store the player health, if the health reaches 0 show the game over screen, etc. The computer reads the code and does exactly what it says. But to get from you typing out the code to the computer running it, there are a couple of steps crucial to understanding (and a good first step in tackling computer science as well).
- First, you as a the human/computer programmer sit behind a computer and write code into a program known as an IDE (integrated development environment). Basically, a text editor designed for computer programming.
- Then, that code is compiled which means it’s broken down into 1’s and 0’s for the computer to read (i.e. computer language). At this level, the code (machine code) is unreadable to humans, but the computer knows exactly what to do.
- Now it can be executed and you can begin to use your program, play your game, or look at your website.
Like with our real-world languages, there are also a number of different coding languages. Which one you should learn to become a coder depends entirely on the types of games you’d like the make and the game engine you choose.
One good thing about coding languages, is that pretty much all of them share the same core concepts. This means you can learn one programming language and have a basic understanding of others. It’s just the syntax (grammar) that’s different. Of course, some languages have their own quirks and way of doing things (especially based on how close it is to machine code), but at its core – there are the fundamental concepts of coding:
- If statements
Learning one coding language opens up all others and makes the learning process to become a coder much easier. So if you want to know how to learn to code, always start by just picking up these fundamental aspects in any language! Of course, you may want to dive more into what coding is, so before moving to the next section, you can check out our What is Coding and Why Learn to Code? article or our What is a Developer? Getting to Know the Industry article.
Choosing a Game Engine
Coding games and learning how to become a coder can be a difficult journey. What can make it a lot easier though, is to use a game engine. A game engine gives you the basic foundations such as rendering, physics, inputs, etc, so you can jump straight into coding all the good stuff.
Many people want to code their own game engine from scratch at some point, although for a beginner, I do not recommend that. Creating the engine, in many cases, can take longer than the actual game – and it’s a very difficult and tedious process even for professionals who’ve made computer programming their life. Using an already established engine developed by computer programmers can help make your development process a lot shorter and create a much more polished final product. Plus, it allows you to focus on the foundations as you explore what computer programming has to offer in case you pursue things like software development or web development.
Here’s a list of some popular game engines:
- One of the most popular game engines out there for beginners, Unity gives you tools to create pretty much whatever type of game you want. 3D, 2D, VR, AR, multiplayer, etc.
- Coding Language: C#
- Pros: most popular game engine – even for professional computer programmers, large amount of online learning resources, very versatile.
- Cons: compared to the other engines, Unity has disadvantaged graphics and 2D.
- Unreal Engine
- Unreal has a focus on graphics and is used by many AAA studios.
- Coding Language: C++
- Pros: graphically amazing, used by AAA studios.
- Cons: large game file sizes.
- Godot is an open-source game engine with a heavy community focus. It’s similar to Unity in what you can create and is constantly growing as more people are learning computer programming.
- Coding Languages: GDScript (similar to Python), C#, C++
- Pros: open-source, lightweight, versatile, excels at 2D.
- Cons: less feature-rich compared to other engines, not a large number of learning resources.
- Phaser is an open-source framework for Canvas and WebGL games.
- Cons: limited to what platforms you can build to, might require some web development knowledge too depending on how you host your games.
- GameMaker has been around for quite some time and is great for creating 2D games.
- Coding Languages: GML, C++
- Pros: great 2D, large amount of learning resources.
- Cons: uses its own custom language.
- Pygame is a framework for games made with Python.
- Coding Language: Python
- Pros: lightweight Python framework.
- Cons: Python is not generally used for game development.
That’s quite a list, but where should you start when you’re discovering how to learn coding?
I’d recommend trying out a few engines to see which one suits you best, and even reading a bit more about each one. If you’re not sure about what types of games you’ll want to create, I’d recommend either Unity or Godot for their versatility. However, there is no one right way to become a computer programmer. As long as you want to learn, and have the drive to develop your programming skills, any engine is fine. Either way, a game engine will help ease the process of learning how to code immensely!
Creating Your First Game
So you’ve got your game engine, now it’s time to start coding a game and become a coder finally. Yes, just doing it is part of the process of how to learn coding!
You may have an idea of what game you want to create, but I can almost guarantee that the scope is too large, especially for a first computer programming project. When first learning to create games and writing code, you need to start small. Most people recommend re-creating a simple retro game such as Pong or Breakout. These games have a small scope, basic graphics, and simple mechanics.
Okay, so we’re ready to make a game but what do we actually make first? I always like to start with the player controller. That being a platformer character or a paddle from Pong, try and create the player first and we can build out from there.
Next, what does the player need to do? In Pong, they need to hit a ball, so we can implement that. When coding a small game like this, it’s always best to start with the player and expand from there. Of course, when you become a coder, you’ll find what works for you the more projects you build.
- Begin coding the actual player so you can get a feel for the game.
- What does the player do? Start coding that into your game so your player has something to interact with.
- What is the player trying to achieve? This may involve coding the win state for your game. In Pong, for example, this is detecting when the ball has gone past an opponent’s paddle.
Knowing or Understanding Coding
There’s a difference between knowing how code works, and understanding how code works. Knowing is taking in the information and having that stored in your mind. Understanding involves being able to apply it in new circumstances. Both are vital and come at different times. Watching courses and tutorials will give you the knowledge of how to code, but only through doing it yourself – will you truly understand it and actually learn how to code. Don’t assume just because you know what variables, arrays, loops, and functions are that you’ve mastered everything computer programming!
When you’re learning coding, I highly recommend you follow along and create the content alongside the presenter/teacher as that’s the best way for it to soak in. Also, work on your own projects. Giving yourself a coding challenge will help you develop your problem-solving skills and further understanding of the coding language/game engine.
