Need help with Event "CHAT_MSG_SYSTEM"

[Akatosh]

I need a way to filter the event "CHAT_MSG_SYSTEM", for friends online / offline and guild online / offline.

And discard the rest.

(or another event that fires when a friend / guild mate, conect or disconect).

I need a conditional (for Kgpanels) that change the color of a text when a friend or guild mate conect or disconect, using that event.

how can I do it?

Thanks!!

The online/offline messages don't distinguish between friends and guildmates, so you have to scan your friends list and figure that out yourself:

local ONLINE = ERR_FRIEND_ONLINE_SS:gsub("%%s", "(.-)"):gsub("[%[%]]", "%%%1")
local OFFLINE = ERR_FRIEND_OFFLINE_S:gsub("%%s", "(.-)")

local function IsFriend(name)
	for i = 1, GetNumFriends() do
		if GetFriendInfo(i) == name then
			return true
		end
	end
end

ChatFrame_AddMessageEventFilter("CHAT_MSG_SYSTEM", function(frame, event, message)
	local action = "OFFLINE"
	local _, name = strmatch(message, ONLINE)
	if name then
		action = "ONLINE"
	else
		name = strmatch(message, OFFLINE)
	end
	if not name then
		return
	end

	if action == "ONLINE" then
		if IsFriend(name) then
			-- A friend came online.
		else
			-- A guildmate came online.
		end
	elseif action == "OFFLINE" then
		if IsFriend(name) then
			-- A friend went offline.
		else
			-- A guildmate went offline.
		end
	end
end)

For kgPanels you'd probably want to put that in the OnLoad script for your panel. I assume you only want to change the color temporarily, in which case you'd want to (a) change the color and (b) set a variable indicating what time the color was changed in the above function, and then add an OnUpdate script to change the color back to the default after a specified amount of time:

self.text:SetTextColor(0, 1, 0) -- change it to green
self.colorTimeout = 5 -- change it back 5 seconds from now

OnUpdate:

if not self.colorTimeout then
	return
end
self.colorTimeout = self.colorTimeout - elapsed
if self.colorTimeout <= 0 then
	self.text:SetTextColor(1, 1, 1) -- change it back to white
	self.colorTimeout = nil
end
