Hi, I decided to get back into C++ by making a project with a clear criteria. This project uses some C++17 features like structured binding so a modern-ish compiler is required. This is my first Show HN post, so feedback and code review is

It does get easier to read and code over time. As an aside, the C++ in this post is pretty much as elegant as it gets.

> Unreal's game-level memory management system uses reflection to implement garbage collection. Yep. Game-level garbage collected C++. Which is exactly what I said, I just a didn't mention GC on C++ to avoid obscuring my po

You asked a question about the array and I answered it. Yeah I missed the part where you said mmap. There's libraries that make that safer, but clearly there's a preference for working with the raw tools here. > Otherwise have

Why couldn't you use a structure to encapsulate the table and then have the destructor to deallocate the the array? This is how vector works.

They do not have garbage collection. You're conflating game development with game engine development. When a big powerful, flexible, C++ engine has been written for you, you can use C# or JavaScript or BluePrints to use the engine to m

Right, you use C++ to build game engines, you can use scripting languages on top of that once the engine is built.

Unreal and Unity were built using C++. They offer garbage collected languages on top of their C++ game engines for scripting game logic. Any significant modifications to the engine will need to be done in C++

Can you give me an example of soft real time game that isn't hurt by the presence of a garbage collector?

It's gross because it's written in "C with namespaces and overloading" Preferring #define for constants over constexpr is 100% the result of C++ bigotry. It's a laughable decision. constexpr gives you the power of t

Do you know why Microsoft rewrote Minecraft in C++? Games can certainly be successful in spite of performance problems, but why purposefully introduce them in the first place? In the case of Notch, he used Java because he was most skilled a
