C++

Hi! I'm new here and new to game development, but not new to C++. I actually found you through Ogre 3D's website. I've been working with Ogre 3D for some time and development is very slow and tedious. I basically managed to make it work using SDL2 for sound, keyboard and gamepad, but I'd have to dive into even more tedious job of making tools like level editor, etc. And I haven't even mastered Ogre 3D after 4-5 months, feels to me like I'm not going to get to the needed skill level to make a game that I imagined, it would probably take many years before I reach that level. I watched your promotion video and it looks like your development environment allows users to actually focus on making the game, but I also noticed that you're saying C# is used as a scripting language, which I'm not familiar with at all, so I was wondering if it's possible to write the code in C++ somehow? And also I'm wondering if there will be a performance loss in comparison with Ogre 3D, since C++ is much faster than C#?

Just to clarify my concerns about C#. If I understood correctly C# compiler produces bytecode which is then used by JIT compiler to compile that bytecode into machine code during runtime and that's why C++ compuler code is way faster, the fastest possible with optimizations turned on, because it's immediately native to the machine. And this is everything you already know, but I was merely stating one of my concerns. Second concern is that I won't be able to directly use any of my C and C++ libraries. I've read about Unity having ability to use DLL's if developer specifies functions and maps arguments to types that are similar or equal in C#. Is maybe your engine having similar ability and if so can you please provide me the link with tutorial explaining that? Thanks!

Hi!

You can use C++ code or code made with another language. Need to make a dynamic link .DLL library. On GitHub you can download SDK. Easiest way to use "Sources\Engine\NeoAxis.Core.Native" library to add your code inside it.

But! C# is not slower than C++ in total. It running as an machine code same way as C++ code. C# code may be slower on certain tasks, but the .NET compiler evolves very quickly. Just one page about latest .NET optimizations: https://devblogs.microsoft.com/dotnet/performance-improvements-in-net-6/. C# gives 2-10 times faster and safer development, the such development optimization has a big sense. For very critical scenarios you can use C++ in a pair with C#.
