Cyclic array access Lua vs C-languages

wrap

--
-- In C style languages you can cyclically access elements of an array using the modulus operator
--
-- Lua-style psuedo code:
--
-- array = {'a', 'b', 'c', 'd'};
-- i = 0;
-- while true do
--     print(array[i % array.count()]);
--     i++;
-- end
--
-- Will print abcdadbcdadcd... for ever
 
--
-- Lua having arrays indexed from 1 makes this a pain in the ass
-- Here's how to translate the above from c-style language to Lua
-- 
 
array = {'a', 'b', 'c', 'd'}
i = 1
while true do
    print(array[i % #array + 1])
    i = i + 1
end
 
-- Will print bcdadbcdadcd...
-- Note that it starts from 'b' so that may require special case code for the above type of loop.
