What you should do? Read this all, if you don't understand something, just leave it to later.

http://www.lua.org/manual/5.1/

My advices:

- don't ever give up

- use wikipedia and google for definitions

- write your own examples

- use wiki http://wiki.multitheftauto.com/

- use notepad++

- if you want to take something from other res to your res read all lines slowly, if you don't understand function watch wiki.

IN LUA - CONSOLE

  
function myfirstfunction() 
    print("Hello World") 
end 
  

IN MTA

  
function myfirstfunction() 
    outputChatBox("Hello World") 
end 
addEventHandler(.... 
  

if you have problem with your script use [lua] tags
