Add timer via OmniCC + 2 other small Questions

[hank]

Hey there,

i write an small Strength of Soul (+ slowimmun buff 4-piece pvp set) oUF Plugin but ive no idea how to add a Timer like OmniCC do for Actionbuttons - may u can help me there? (btw there IS a timer but i would be better to see this overlay u know?)

Code (3files):
http://pastebin.com/fxnH93Gd
(CreatePanel, CreateShadow and Point are Tukui functions btw)

and the other 2 small question that came in my mind:
1.
Does

do
   stuff
   stuff
   stuff
end

make any sense? I mean the "do" without something like "for .. do" ?
Cause i saw code like this many times.

2.
Does this makes sense:

f:RegisterEvent("PLAYER_ENTERING_WORLD")
f:SetScript("OnEvent", function()
  stuff
  f:UnregisterEvent("PLAYER_ENTERING_WORLD")
end)

PLAYER_ENTERING_WORLD only occurs 1 time after /rl, correct? So why should I unregister this event? It just get loaded again after the next /rl?

Thanks in advance
hank

as far as the overlay goes i have no idea (check OmniCCs code)

question 1:
do ... end simply defines a chunk/block in the code anything local to that chunk can only be accessed from within the chunk as such it can be used to separate out code see http://www.lua.org/pil/1.1.html and http://www.lua.org/manual/5.1/manual.html#2.4.2 for more details

question 2:
PLAYER_ENTERING_WORLD fires every time you see a loading screen so if you use it to initialize some settings on login then you should unregister it after first use

OmniCC automatically adds timers to the widget-type Cooldown (unless told not to more or less), so if you want for OmniCC to provide the timer just add a Cooldown-frame.

Thanks u both

Problem with the Cooldownframe is, that it resets everytime UNIT_AURA occures and ive no idea how to stop it.

I created a sos.cd frame now +

if sos.cd then
	sos.cd:SetCooldown(GetTime(), duration)
end

the duration is correct but yeah as I said...
i tried to add sos.cd:UnregisterEvent("UNIT_AURA") when its shown but that doesnt helped.
