... Ok, that is legitimately impressive, from a technical standpoint.
Lua is a high level, not exactly very 'fast', very performant language. It is designed to be very, very human readable, and coding noob friendly.
Getting a 3D physics engine to work ... in lua... is not something I would have thought possible.
Usually you need to use a much lower level language to ... actually do that.
EDIT:
A few other commenters have now pointed out that this is actually using LuaJIT... which passes Lua code to a C compiler, quickly translates and then compiles in C, and then runs in C.
So, that makes much more sense, its functionally running in C, a lower level, compiled code language.
Still impressive nonetheless!
As someone who can't wrap my head around lua syntax, I will have to assume I simply have too much coding experience
I know what you mean lol, but Lua is very noob friendly... it goes fairly far out of its way to make many common functions and data types as compatible with each other as possible... so thats another way it is generally more slow, but also more forgiving, won't just totally error out and be frustrating to a beginner coder.
