Help getting cooldown duration on spells with recharges

[Brusalk]

Hello!

I've been looking high and low and I haven't been able to find any information on this. (Probably because it's kind of obscure, and the only reason I'm looking for it is for backwards compatibility reasons)

Anyway, what I'm looking for is a way to determine the amount of time until a spell that has charges (conflag for example) will hit 1 charge when it first hits 0 charges.

So, for example, take conflag with 2 max charges and a recharge time of 12 seconds. If the player was to cast 2 conflags back to back, I would expect GetSpellCooldown() or GetSpellCharges() to return a duration of 12-GCDDuration, because it took 1 GCD to cast the first GCD, so you've already recharged 1 GCDDuration before the chgarges first hit 0 charges.


Both GetSpellCooldown and GetSpellCharges return 12 seconds as the duration, and the start is the same for both.


I'm looking for a way to determine how much time there is until a spell with charges goes from 0 charges to 1 from the time when it hits 0 charges.


Any help you can give me would be very appreciated! Thanks

I'm not entirely clear on what you're trying to do, but if you're having trouble displaying the correct cooldown on spells with charges, I'd suggest looking at OmniCC, as it shows the correct time remaining until I can cast the spell again once I hit 0 charges.

GetSpellCooldown returns the timestamp of when you first cast it and its duration. All you need to do is subtract the current time from that to get how much time is left.

Here's a complete example.

local text = UIParent:CreateFontString(nil, nil, 'GameFontNormal')
text:SetPoint('CENTER')
CreateFrame('frame'):SetScript('OnUpdate', function()
 local start, duration = GetSpellCooldown('conflagrate')
 if duration > 2 then
  local timeLeft = start + duration - GetTime() -- time until it recharges the first charge, in seconds
  text:SetFormattedText('%d seconds until conflagrate', timeLeft)
 else
  text:SetText('Conflagrate not on cooldown')
 end
end)

@Semlar,

That's not the problem I'm having.

The problem is that the duration for recharge spells (namely Conflag) is ALWAYS 12 seconds, regardless of how much actual time there is left.

The duration is 12 seconds. The duration of the cooldown doesn't change.

The time left is determined by adding the duration to the start time and subtracting the current time.

Okay, so for an example of what I'm trying to describe:

Normal CD (12 second Cooldown):

Cast @ 10
Start = 10
Duration = 12
Start + Duration = 22


Recharge CD (12 second recharge):

Cast 1 @ 10
Cast 2 @ 12
Duration = 12
Start + Duration = 24

However, the expected time for the charges to actually hit 1 is @22sec. (As 2 seconds of recharge have already happened at the time you casted the spell a second time and it's charges hit 0)
