Basic lua: Functions
From The Official Visionaire Studio: Adventure Game Engine Wiki
Tables are one of the features of Lua script, that make the scripting language so dynamic & easy to use, as they allow us to easily create tables, insert, remove & sort data. Tables are often comprised of arrays that usually involve keywords - or an index number - & a value. Tables can be accessed using multiple different methods.

Creating a function
| method 1: automatically generated index values | |
|---|---|
local t = {1, 2, 3, 4, 5, "six", 7, "ate", 9} -- automatically assigns an index number to each value starting from 1
local str = "" -- empty string
for i = 1, #t do -- for 1 to table total, print value of index number
str = str .. t[i] -- add current table index value to existing text data in the str variable
if i < #t then str = str .. ", " end -- if i is less than table entry total then insert ", " into the str variable
end
print("table data: " .. str) -- print the table data
print( "table entry total: " .. #(t) ) -- print total of table entries
