Help expanding an Addon

Transformis · 03-11-13, 09:14 PM

I went looking for an addon that could detect when someone was spam-clicking group food items. I found one but it was outdated. I edited it to work with Banquet of the Wok, tested it and it works. Now I'd like to expand it to monitor all the new MoP banquets in a single addon. Here's what I'm working with so far.

Code:

local Food_Hog_Wok = CreateFrame("Frame", "Food_Hog", UIParent)
Food_Hog_Wok:SetScript("OnEvent", function(self, event, ...) self[event](self, ...) end)
Food_Hog_Wok:RegisterEvent("COMBAT_LOG_EVENT_UNFILTERED")

local alert, started, players = "%s is spam-clicking the Banquet of the Wok! (%s)"

function Food_Hog_Wok:Print(msg)
	DEFAULT_CHAT_FRAME:AddMessage("|cff33ff99Food_Hog|r: " .. msg)
end

function Food_Hog_Wok:UNIT_AURA(unit)
	if GetTime() - started > 180 then
		self:UnregisterEvent("UNIT_AURA")
		return
	end
	if UnitAura(unit, "Food") then
		local name, expiration = UnitName(unit), select(7, UnitAura(unit, "Food"))
		if players[name] and players[name].expiration ~= expiration and expiration - players[name].expiration < 20 then
			players[name].count = players[name].count + 1
			if players[name].count > 2 then
				self:Print(alert:format(name, players[name].count))
			end
		end
		players[name] = players[name] or { count = 0 }
		players[name].expiration = expiration
	end
end

function Food_Hog_Wok:COMBAT_LOG_EVENT_UNFILTERED(_, event, _,_,_,_,_,_,_,_,_, spellID)
	if event == "SPELL_CAST_START" and spellID == 126495 then
		started, players = GetTime(), {}
		self:RegisterEvent("UNIT_AURA")
		self:Print("Monitoring the Banquet of the Wok!")
	end
end

I'd do something like this:

Code:

local alert = "%s is hogging the %s! (%d)"

local foods = {
	[126503] = true, -- Banquet of the Brew
	[126504] = true, -- Great Banquet of the Brew
	[126492] = true, -- Banquet of the Grill
	[126494] = true, -- Great Banquet of the Grill
	[126501] = true, -- Banquet of the Oven
	[126502] = true, -- Great Banquet of the Oven
	[126497] = true, -- Banquet of the Pot
	[126498] = true, -- Great Banquet of the Pot
	[126499] = true, -- Banquet of the Steamer
	[126500] = true, -- Great Banquet of the Steamer
	[126595] = true, -- Banquet of the Wok
	[126596] = true, -- Great Banquet of the Wok
	[104958] = true, -- Pandaren Banquet
	[105193] = true, -- Great Pandaren Banquet
}

local counts = {}
local endTimes = {}

local started = 0

local f = CreateFrame("Frame", "FoodHog", UIParent)
f:RegisterEvent("UNIT_SPELLCAST_SUCCEEDED")
f:SetScript("OnEvent", function(self, event, unit, spellName, _, _, spellID)
	if event == "UNIT_SPELLCAST_SUCCEEDED" then
		if foods[spellID] then
			started = GetTime()
			self:RegisterEvent("UNIT_AURA")
			print("|cff33ff99FoodHog:|r Monitoring", spellName)
		end
	else
		if GetTime() - started > 180 then
			return self:UnregisterEvent("UNIT_AURA")
		end
		local _, _, _, _, _, _, endTime = UnitAura(unit, "Food")
		if endTime then
			local name, server = UnitName(unit)
			if server and server ~= "" then
				name = name.."-"..server
			end
			local t = endTimes[name]
			if t and t ~= endTime and endTime - t < 20 then
				counts[name] = 1 + (counts[name] or 0)
				if counts[name] > 2 then
					print("|cff33ff99FoodHog:|r", format(alert, name, counts[name]))
				end
			end
			endTimes[name] = endTime
		end
	end
end)

UNIT_SPELLCAST_SUCCEEDED fires a lot less often that COMBAT_LOG_EVENT_UNFILTERED, and gives you the same info for your purposes, so you should use that.

Currently it doesn't track different banquets separately, so if someone clicks multiple banquets repeatedly, it will warn about them, but this seems fine.

Wow, thanks!

This looks a lot simpler than the original.

Should

Lua Code:

if server and server ~= "" then

be

Lua Code:

if name and server ~= "" then

?

No. You'll always have a valid unit token from the UNIT_AURA event, so you'll always get a name from UnitName. You just need to check if the server name from UnitName is both (a) non-nil and (b) not an empty string, so you can append it to the name for cross-realm players.

Oh I see, I hadn't though about the difference between nil, and an empty string. Thank you very much for the explanation.
