Just a really rough engine. Mostly low level code.
I have been working on this slowly over a couple of years. I found a demo (https://lnkd.in/gw6GtmZ) to learn from.
I've also been using this to tryout various ideas in C++ I've had, like a foreach loop. So some of the code is inefficient. But I hope somewhat clever. :D
I used Visual Studio 2019 for the IDE.
