Genesis is a simple game engine based on SDL2 and written in modern C++. The engine is used in my own project [**ArkanoidWithoutAnEngine**](https://github.com/Atennop1/ArkanoidWithoutAnEngine), it appeared when I was doing that project and soon decided to separate the system part into a separate solution, like my first small engine. It's supported on both Windows and Linux, and can be connected as a static library or as a dynamic one. It is also written in a strictly OOP style, with minimal distortions.

You can find information about the structure and components of the engine in [**documentation**](https://github.com/Atennop1/Genesis/blob/master/DOCUMENTATION.md), see usage examples in [**this file**](https://github.com/Atennop1/Genesis/blob/master/examples/README.md) and check installation guide in [**this file**](https://github.com/Atennop1/Genesis/blob/master/INSTALLATION.md)

### Techniques

- Clean OOP and DI

- Custom game loop

- Custom AABB physics simulation

- Self-written smart pointer

### Tools

- SDL2 

- CMake

## Conclusion 

The project became a big boost for me in understanding the work of game engines, the CMake build system and C++ in general. Thanks to it, I understood many things, faced many problems in development and overcame a long way from a simple vector ball output using the Windows API, to this, albeit small, but full-fledged engine, with its own physics, game cycle, memory management system, which can be assembled for both platforms and as a static and dynamic library. Also thanks to it, I understood how to develop and grow further, so now I am moving forward in a new direction, towards new challenges.
