am probably a noob for asking this. I'm guessing Lua is actually http + some other languages
Lua is a different language from what you see roblox has.
Well, in a way. Roblox uses a highly simplified version of it. I'm pretty sure there's some http stuff you can do in roblox.
Roblox isn't really necessarily even Lua. I mean it is, but it is a much easier way of using Lua so that it is more understandable to people of younger ages. To my knowledge Roblox's Lua is the only thing that is usable. If you understand one language though then it's really easy to get used to another. Make sure you use the Roblox wiki for help on specific things. It is a big help and a big time saver! You could also try digging around other people's scripts to learn how to script yourself. Just try to figure out what all of the code is doing. :) Hope I helped.
