Could even just do the logic in c++/c# and have it compile to a DLL, then include the DLL in whatever language, ruby/js/python/whateveryouusehere and use the globally available API to do what you want it to.
Events? Databases? Character data? do it in c, access through API calls. Not hard.
That's right, because programming is an incredibly easy job, poke a key and it works.
Especially when working with an LLM who just tries to pretend that the code you give out will be correct, and you'll pretend it's correct too, until you tell him to add a complication, and all the code that was written shoots you in the face with the force of a shotgun....
Since I'm starting to spell it out, I'll say that Teary uses the standard RPG Maker MV, the standard event generator, not JS, I don't remember having to get down to look at his code when I was trying to break into the game. This means you're going from a language known to LLM to a language not really known to him (but he knows a bit of it, I use LLM myself now).
I also want to say that to work with LLM you need to be a head above him in knowledge of the language, otherwise he will sell you some strange function that doesn't work in the right places.
All in all, the world is not as simple as you think. LLM is incredibly useful, but you have to know how to use it, and that skill alone can take a long time to learn.
And the engine itself does not allow you to relax. For example, take Ruby, which you mentioned. For example, you know that if you load a DLL, because RPG Maker VX uses Ruby 2, your new modern C functions may not work correctly because it won't parse the Windows API right? You know that Joyplay is very bad with caches, and your DLL can just plain go missing because they load resources in parallel with startup (known issue that TOT 7F runs very poorly on Joiplay just because of this)? And there are an insane amount of gems that LLM doesn't know about. It's like saying ‘hey guy, why are you drawing so slow, just train an Stable Diffusion model, and produce 10 drawings per second’. No argument, probably some parts will be good, but the ones that don't come out will be incredibly annoying and may take you longer to fix than if you were writing entirely by yourself.
