Examining Unity's C# coroutine pattern for game effects reveals a practical use case: replacing ugly hand-written state machines with clean, readable coroutine functions. Using C++23's std::generator, the author implements a Unity-style effects manager in under 100 lines that runs per-frame coroutines, advancing each one step per game loop tick. The post also shows how yielding renderable objects instead of side effects enables parallel execution with TBB, making the approach both ergonomic and efficient for game effect systems. ## Full article daily.dev links to this article rather than hosting it.
