You should be more descriptive so the right people can help you.

I have basically no experience and would like to learn mapping and LUA. I know very basic programming

Edit your post silly xD

Lua is not something people will openly teach, get down core elements ex: functions, tables, k and v pairs etc. And then create something and we can check it.

Lua is not quite easy to learn, since you have to understand a lot of programming logic and functions. I started coding in Lua since November 2015, and also had no experience at all back then. But if you're REALLY interested in coding with Lua, I suggest watching this guy: 〈CODE BLUE〉 He made lots of Lua tutorials, and I highly recommend checking him out.

BUT KEEP IN MIND: You need to have an idea of what you want to create first! Otherwise, all the coding knowledge you'll gain will be for nothing.
