[All classes][Health Frames] UNIT_HEAL_PREDICTION

[sadolock]

WoW Freakz link: //
Bug description: The event UNIT_HEAL_PREDICTION doesn't fire on cast time based healing spells (Example : Flash of Light), works only on Healing over-time effects. This event is very useful on healing specs, especially while you're raiding, as the UnitGetIncomingHeals(unit) API updates the Raid Frames health and makes you be more efficient with your mana.
On top of that, the cast time based healings updated on UnitGetIncomingHeals should also add the healing over time effects in the maths, in case it doesn't, just so you know about it too (proof in the Blizzard proof video). For example let's say the unit has Rejuvenation on them ticking for 4k/s and you start casting a Regrowth that will heal for 10k. The overall healing returned on UnitGetIncomingHeals should be the 4k + 10k.
The only part working correctly at the moment is for healing over-time effects, returning the next tick value, which is how it's supposed to work for hots.

You can debug in-game with the following frame:

Code:

local healpredictionFrame = CreateFrame("frame") healpredictionFrame:RegisterEvent("UNIT_HEAL_PREDICTION") local function healPredictionHandler(self,event,...)      local healIncoming = UnitGetIncomingHeals("player")      print("Incoming heal prediction for Player - " .. healIncoming) end healpredictionFrame:SetScript("OnEvent",healPredictionHandler)
