Variables
In Lua, variables are very simple, you don't even have to declare a datatype, all you need to do is assign a value.
Var = 1 Var2 = "Im a var!" Var3 = 2 Var4 = Var * Var3 |
Global Variables vs Local Variables
When you declare a variable in Lua, it is globally accessible unless otherwise specified with local.
GlobalVar = 0 |
local LocalVar = 0 |
Functions
Functions in lua are quite easy as well.
function SimpleAddition(x,y,z) local Sum = x + y + z --only accessible from within this context. SumTimesTwo = Sum * 2 -- can be referenced from anywhere in the current file, or wherever file is loaded. return Sum end |
