Example
local spell, _, _, _, _, endTime = UnitCastingInfo("player")
if spell then
local finish = endTime/1000 - GetTime()
ChatFrame1:AddMessage(spell .. ' will be finished casting in ' .. finish .. ' seconds.')
end
Result
- If you're currently casting Shadowbolt:
Shadowbolt will be finished casting in 1.234 seconds.
Details
For channeled spells, displayName is "Channeling".
Not sure if displayName ever differs from spell in any other contexts.
As of May 10, 2008, this does not return anything while casting Hellfire, Drain Life, or Rain of Fire with my warlock. The correct API for channeled spells is UnitChannelInfo. It takes the same arguments and returns the same values, but is specific to channeled spells.
New in Patch 3.2 (August 2009), returns 'interrupt' as well. Believe this is a boolean value for whether it is interruptable or not, but needs confirmation.
Also, the official WoW 3.2 patch changes page lists the returns as:
name, nameSubtext, text, texture, startTime, endTime, isTradeSkill, castID, interrupt
Didn't see 'castID' in there before, so added it to the returns list above. Assume it's a number, but this and the return type of interrupt need to be confirmed
