"GetTotemInfo" help

[Jonisaurus]

I'm trying to create a function that is triggered by "UNIT_POWER" and checks whether I have a totem active or not.

I'm trying to use the "GetTotemInfo" function for this, but I'm not succeeding.
There are 4 returns for this function

haveTotem, totemName, startTime, duration = GetTotemInfo(1 through 4)

here is what they do each:
http://www.wowwiki.com/API_GetTotemInfo

Only one argument (integer for each element, 1 through 4).

Now I'm using i as a variable

for i=1,4 do

for the argument, but that's not the problem.

I need help setting up a functon that checks for each element if there is ONE totem active or not, (NOTE: totemName returns "" instead of "nil" when there is no totem active).

Thank you!

local function HasActiveTotem()
  local active = false
  for i = 1, 4 do
    active = active or GetTotemInfo(i)
  end
  return active
end

HasActiveTotem() would return true/false depending if there is minimum one totam active or not.

You don't even need to store a variable. If you only want to know if any totem is active, you can return out of your function immediately as soon as you find one, without continuing to loop through the rest of the totem slots. You also don't need to explicitly return false, as a nil value is the same.

local function HasActiveTotem()
     for i = 1, 4 do
          if GetTotemInfo(i) then
               return true
          end
     end
end

It's true, not sure why I wrote what I did... :'(

I think you guys made a mistake in thinking that "haveTotem" returns anything else than "true", because it doesn't. It in fact tests whether one has the TOTEM REAGENT, so if one is able to cast any totem of that school. It doesn't test for active totems.

I confirmed this ingame using this macro

/run local haveTotem, name = GetTotemInfo(1) if haveTotem then print("b") end

it always prints "b", regardless of whether I have an active totem or not. It does however not work on my druid.

I think there is no direct way to check for active totems, one has to use

if name == ""

because "name" returns nothing if there is no active totem.

local frame = CreateFrame("frame")
frame:RegisterEvent("PLAYER_REGEN_ENABLED")
frame:RegisterEvent("PLAYER_REGEN_DISABLED")
frame:RegisterEvent("PLAYER_LOGIN")
frame:RegisterEvent("UNIT_POWER")

local function HideAndShow(self, event, ...)
	local unitId, resource = ...
	local class, classFileName = UnitClass("player")
	if unitId == "player" and resource == "MANA" and classFileName == "SHAMAN" then
		print("ABC")
		for i = 1, 4 do
			local haveTotem, name = GetTotemInfo(i)
			for o = 1,4 do
				local frame = getglobal("XiTimers_Timer"..o)
				if event == "UNIT_POWER" and name == "" and event == "PLAYER_REGEN_DISABLED" then
					frame:Show()
				else
					frame:Hide()
				end
			end
		end
	end
end

frame:SetScript("OnEvent", HideAndShow)

Okay, this does not work. Can you help me here? Please :P
There is something wrong with that code, and I'm too tired to find the error.
