Disregarding Lua and rbx.Lua (I don't really know them), you don't have much experience in programming languages, it seems (not that I'm really one to speak). HTML isn't even considered a programming language, and VB6 is cheating, lol XD Java is closest to what Ruby is probably like.
And I have no idea if you're talking about RMVX's actual platform and stuff or the scripting function.
