![]() ![]() There is no need for the programmer to know how this function is implemented or what is the algorithm required to correctly determine if two shapes are overlapping. For example, it is not rare for a game engine API to expose a function called " IsColliding()" that developers can invoke to check if two game objects are colliding or not. To really understand how this API thing works, let's put it into context. This API allows the programmer to call engine functions and perform hard tasks as if they were black boxes. Game engines and game frameworks usually expose an API to the user. ![]() These engines can be small and minimalist, providing just a game loop and a couple of rendering functions, or be large and comprehensive, similar to IDE-like applications where developers can script, debug, customize level logic, AI, design, publish, collaborate, and ultimately build a game from start to finish without the need to ever leave the engine. But just so we are all on the same page, let's quickly review what game engines are and what they help us achieve.Ī game engine is a set of software tools that optimizes the development of video games. ![]() If you are reading this, chances are you already have a good idea of what a game engine is, and possibly even tried to use one yourself. Create a C++ Game Engine (by ) What is a Game Engine? If you are looking for a comprehensive video book on how to write a C++ game engine, this is a great starting point: Create a 2D Game Engine with C++ & Lua. I won't go into too much technical detail or explain how all these elements are glued together via code. That being said, this will not be a coding tutorial. I'll explain the main elements that are required in a game engine, and give some personal recommendations on how I like to approach writing one from scratch. This article will go over some of the fundamental building blocks that are required to create a simple game engine with C++. Game development is serious business and it can be a powerful tool to learn serious CS concepts. Sepideh ChakavehĪs always, she is absolutely right! If we expose what is hidden under the development stack of any modern game, we'll see that it touches many concepts that are familiar to any computer science student.ĭepending on the nature of your game, you might need to dive even deeper into more specialized areas, like distributed systems or human-computer interaction. "Some people think games are kid's stuff, but gamedev is one of the few areas that uses almost every item of the standard CS curriculum."- Dr. Game development has always been a great helper to get my students motivated to learn more about more advanced computer science topics. So you want to learn more about game engines and write one yourself? That's awesome! To help you on your journey, here are some recommendations of C++ libraries and dependencies that will help you hit the ground running. (This blog post was originally posted on ) ![]()
