When programming a new game, most of the time you implement some basic features and start from there. As the game gets bigger, your code gets more interwoven, and the classes bigger. And before you know it you end up with spaghetti code and god classes, and that’s the last thing anyone wants.

Let’s assume we’re programming a racing game, and we have a class called RaceCar. Soon enough that class will contain a method to update it’s state, to draw it onto the screen, to accept user input, etc. It will become huge with all kinds of different functionality in there. So how can we divide up our game so it’s nicely split up into modules and classes? Just read on and learn ;).

The game loop is the heartbeat of every game, no game can run without it. But unfortunately for every new game programmer, there aren’t any good articles on the internet who provide the proper information on this topic. But fear not, because you have just stumbled upon the one and only article that gives the game loop the attention it deserves. Thanks to my job as a game programmer, I come into contact with a lot of code for small mobile games. And it always amazes me how many game loop implementations are out there. You might wonder yourself how a simple thing like that can be written in different ways. Well, it can, and I will discuss the pros and cons of the most popular implementations, and give you the (in my opinion) best solution of implementing a game loop. (more…)

This guide describes the coding style that I developed over the years. My style isn’t very widespread. As a matter of fact, I don’t know anyone who comes even close to the weird way I program. But I like it and want to share it with you anyway (you lucky bastard!). I use it for all kinds of programming languages: C, C++, Java, C#, Python,… .
