Sample OOP/ECS/DOD project (C++) for an internal Unity lecture in 2018, aimed at junior/future engineers.
This is a super-simple C++ "game" (just a bunch of sprites moving around with very small amount of logic really) I made to show how one might go from a very traditional OOP style GameObject/Component based code to an ECS (Entity Component System) / DOD (Data Oriented Design) based code.

macOS (uses Metal, Xcode 9 project in
I used some excellent other libraries/resources to make life easier for me here:
