Need help understanding this lua code

[jon]

Hey, Ive been trying to understand the different functions in this lua for awhile now,

Can anyone break this down for me? My brain just cant handle it.

Thanks in advance, Jon

-- Author : Bitt (Alliance Rogue) on Jubei'Thos
--
-- Version 0.3 Date: 9 July 2006
--     Implemented an options dialog which allows toggling of whether the
--             delay time is adjusted for lag.
--     /cdo displays the Options dialog for Chat Delay.
--     Saves the state of the Lag Adjust selection between game sessions
--
-- Version 0.2 Date: 8 July 2006
--     Can be called as a slash command with comman separated arguments
--             EG: /cdel Five seconds have elapsed,5
--
-- Version 0.1 Date : 25 June 2006
--     Allows a message to be delayed by a number of seconds before being
--             sent using SAY
--     Adds 2 x latency to the chat delay

perhaps be more specific on what you need help with? Your post comes across as saying "Teach me Lua!" which frankly, no one wants to do.

I am sure there are plenty of us more than willing to help you understand things if you can tell us exactly what part you are having trouble understanding.

What im trying to do is get this to delay a whisper instead of a /say.


Thanks again, Jon
