How to use Generic For?

This was answered here.

A generic for loop looks like this:

for index,value in pairs(table) do

end

The variables index and value can be replaced with anything. table should be a valid table.

The code will loop through once for every value in the given table. Each time it loops, the 'value' variable will be equal to the value it's currently passing over, and 'index' will be equal to the number of times it's already looped. In programming lingo, this is called an iterator.

Here's an example:

local stuff = { "Apple", "Pear", "Orange" }

for i,v in pairs(stuff) do
    print(i)
    print(v)
end

--[[

Output:

1
Apple
2
Pear
3
Orange

]]
