What is the separation of concerns in a C++ game engine?

What is the separation of concerns in a C++ game engine?

Separation of concerns is a design principle that divides a program into distinct sections, each addressing a separate concern. In a C++ game engine, this means organizing code into modules like graphics, physics, and input handling, making it easier to manage and maintain.

Can you give me an example of how this is implemented?

Sure! For instance, in a C++ game engine, you might have a Graphics module responsible for rendering, a Physics module for handling collisions, and an Input module for user controls. Each module interacts through well-defined interfaces, allowing for independent development and testing.

What are the benefits of using this approach?

The benefits include improved code maintainability, easier debugging, and the ability to reuse modules across different projects. It also allows teams to work on different parts of the engine simultaneously without conflicts.

Are there any downsides to this approach?

Yes, potential downsides include increased complexity in managing module interactions and the overhead of ensuring that all modules communicate effectively. It can also lead to performance issues if not designed carefully.
