I need some help with events

[evil_oatmeal]

Hey there, this is my first time hanging with lua and generally thje guts of a wow mod, so here's my question:

I'm trying to create something very simple, a mod that reacts to things being typed in the chat frame. Is this possible? could I use some sort of CHAT_MSG event for this? Scenario:

Let's say i had succesfully made this mod, then, I log in to the game and type the word 'cake' the mod would respond by putting a message in the chat frame saying 'You typed cake! Good job!".

Is this doable? And if so how? Thanks in advance for th help

Nobody likes me.... oh well... I'll just go sit in the corner....

yes, it is possible. register the event CHAT_MSG_CHANNEL and once it fires grab the arguments arg1 (the message), arg2 (the sender), arg9 (the channel). Now do your checks (only in specific channel,...) and use string.find() to check if the word you're looking for is in the parsed message...

aha.. cool... I think I understood that... I'm new to this kind of thing, I'll give it a try
so... i would do something like?:

RegisterEvent("CHAT_MSG_CHANNEL")

function OnEvent()

if (event == "CHAT_MSG_CHANNEL") then

and that's as far as i get. Sorry for being a noob

[Maia]

exactly. Now add something like

local message = arg1
local sender = arg2
local channel = arg9
if channel == whatever and string.gsub(message,...) then
   -- do whatever
end

I just never memorize how string.gsub works, but you can find the info at lua.org.

OH! thank you! that's great I'll try it out when I get home today

Hmm... it just doesn't look right, and I keep thinking string.find would be better somehow. I really apreciate you helping me out though

RegisterEvent("CHAT_MSG_CHANNEL")

function OnEvent()

if (event == "CHAT_MSG_CHANNEL") then

local message = arg1

local sender = arg2

local channel = arg9

if channel == whatever and string.gsub(message,...) then

   -- do whatever

end

[evil_oatmeal]

In my code (for what I'm thinking in my head) local sender/channel is irrelevant, and it might seem that channel would be a problem, but I'm pretty sure it won't. So I was thinking:

RegisterEvent("CHAT_MSG_CHANNEL")

function OnEvent()

if (event == "CHAT_MSG_CHANNEL") then

local message = arg1

local sender = arg2

local channel = arg9

if string.find(s, whatever) == whatever then

   -- do whatever

end

string.find should return "whatever" if there is "whatever" written in the chat right?
and if this is the case then then the script would do something whenever someone write "whatever" in the chat? (I think I'm starting to get the hang of this, oh, it's so fun.)

of course you don't need sender and channel - I just assumed you might want to parse that info as well. As for string.find, check out the lua manual:
http://www.lua.org/manual/5.1/manual...df-string.find

but basically you need something like

message = "Hey evil" -- well, in your case it's rather the argument passed by the event
checkFor = "evil" -- the word you want to check
if string.find(message, checkFor) then
  -- do whatever you want to do here 
end

Finally, I'd like to suggest studying some basic macros, and once you know how lua and the wow api works, move on to tiny addons and try to understand what they do by looking at their code.

Well, thanks I'll look around and try to get some more knowledge on how sutff works
