LUA - Get time left before spell is off cooldown

[Deleted]

What is the simplest way to get the time left before spell is off cooldown ?

I'm trying to track Vampiric Blood (blood dk spell).

Can't really find the proper way to do it with GetSpellCooldown. Duration is not helping much.

local s, d, e = GetSpellCooldown("Vampiric Blood")

s+d-GetTime() will return the time left

[dennisdkramer]

start + duration is equal to expiration time, so just

e - GetTime()

it helps to think of these things as large numbers rather than temporally. Expiration time is a time in the future, so its a time number that is bigger than the current time number. Simply subtract the current time number from it and this equation will process towards 0 when the spell comes off cooldown.

e isn't expiration time, but enable. returns 0 if the cooldown starts when the effect finished (i.e. Stealth) or 1 otherwise

Oh yeah derp I'm off the ball today. On a related note I was going to mention to the OP that you really should name your variables something that is more clear than just a single letter. The processing savings of a shorter variable name are negligible and when you start making more complex functions you might end up bamboozling yourself in a similar way to how I just did

If you just wanting to track the cooldown, Why are you not just using Cooldown Progress (Spell) that is built into WeakAura's?

You are aware that there are other addons than WA right?
+just becouse you want to know a cooldown of something doesn't mean you want to see it in your screen
