Achievement broadcast hook

[Soeters]

I'm trying to make my addon Ontario modify the blizzard achievement broadcast instead of printing a new line.
I've searched in AchievementUI.lua from WowCompares but I couldn't find the broadcast function which prints the ACHIEVEMENT_BROADCAST or ACHIEVEMENT_BROADCAST_SELF function.

Does anyone know either the broadcast function, or another way to modify the global string to add the points the achievement provides.

Wowwiki.com has a list here : http://www.wowwiki.com/Events/Achievements.

A little playing around with the code should help you track down the exact one you want but whether any of them also hold the amount for either that achievement or a total figure I don't know.

Thanks I didn't think to events.

Now I only have to do some work around those events with patterns to retrieve the achivement name so that I can get his points.
I think I can do something with that function ChatFrame_MessageEventHandler(self, event, ...) but I don't know if it's protected or not.

Here's some minimal code that may help you get the gist of it. Bear in mind I write my addons without xml files so they're pure lua.

Feel free to download my CatchAndPlay addon which is the smallest one I have that checks the events and outputs the result. You should be able to see what I did with that and thus how you can implement your own addon for this purpose.

local function MyAddon_ExtractAchievementDetails(self,...)
     local firstArgument = select(1,...);
     local secondArgument = select(2,...);

     or

     local firstArgument, secondArgument = select(1,...);

     print(firstArgument);
     print(secondArgument);



end

-- Load any variables and display welcome message
local function MyAddon_LoadVariables(self)
             -- Do Stuff Here to Prepare the Addon
       	self:UnregisterEvent("VARIABLES_LOADED");
end

-- Track Events as required
local function MyAddon_OnEvent(self,event,...)
        if ( event == "VARIABLES_LOADED" ) then 
                MyAddon_LoadVariables(self);
        elseif ( event == "CHAT_MSG_ACHIEVEMENT" ) then
                MyAddon_ExtractAchievementDetails(self,...);
        end
end

-- Register Events and make EventFrame
frame = CreateFrame("Frame","DescriptiveFrameName",UIParent);
frame:RegisterEvent("VARIABLES_LOADED");
frame:RegisterEvent("CHAT_MSG_ACHIEVEMENT);
frame:SetScript("OnEvent",MyAddon_OnEvent);
