I have been using lua a lot recently and it fucking sucks lol. The language itself is tiny and great don't get me wrong and also you can't do anything with it. What you'll need to figure out instead is whatever jank ass mutation-heavy api someone half-accidentally exposed to it from the real stack. And of course it'll be a modified lua 5.1 or some shit, possibly with some of its most powerful and flexible features stripped out.

I haven't yet run across a lua integration that was actually reasonable to use. Every time it's a choice between "just hack in what I need to but there is no way to verify I've accounted for all the edge cases and it will be fragile as fuck" or "spend dozens of hours wrapping the exposed api in a safer and more usable OO or FP interface."

Oh also I hope you like implementing build systems virtually from scratch, and also dealing with every downside of C if you need anything more powerful than prototypical inheritance.

Six months of professional lua work has really, really drilled into me that a programming language isn't shit without its ecosystem, and it's meaningless to discuss one apart from it. I haven't used blueprints but it sounds a lot better than any lua system I've worked on.

The only really fun part is you'll often come across an undocumented function that someone obviously forgot to remove or didn't understand the implications of and you'll get DEEP system access through abusing it, or even just a straight root shell. No joke.
