Fire quickly if they don’t deliver. It’s provocative. Some love it. Some hate it. But everyone talks about it. ...

From Object-Oriented to Data-Oriented Traditional object-oriented programming (OOP) encourages you to model game entities as objects with inheritance hierarchies. While intuitive, this approach leads to poor cache locality, rigid hierarchies, and performance bottlenecks. Data-oriented design, particularly the Entity Component System (ECS) pattern, flips this on its head. With Go 1.18+ generics, we can now build type-safe ECS architectures that deliver both performance and flexibility. Let me show you how. The OOP Problem Here’s the typical OOP approach to game entities: ...
