Through this course, I was able to understand the basic overview of a game engine by building one myself, which allowed me to infer that commercial engines likely operate in a similar manner internally. In particular, while looking at the engine and renderer code structured using the Singleton pattern, I was once again able to feel how excellent code can be when a program is built through proper design. By changing project settings in Visual Studio, I learned practical knowledge not typically covered in school classes—such as managing project folders and building engine code as a separate DLL to link it rather than just running a simple executable. This made me feel like I’ve taken another step closer to becoming a professional developer. I believe this will be a great help to those who want to understand game engines.
