TotalAbsorb Element

[zork]

Has anyone worked with this yet?

EVENT: UNIT_ABSORB_AMOUNT_CHANGED

I wrote an oUF element. Not sure how we can fit that in to work with healprediction though. Currently both anchor on self.Health:GetStatusBarTexture().

--[[ Element: TotalAbsorb Bar
 
  Handle updating and visibility of the total absorb status bars.
 
  Widget
 
    TotalAbsorb - A statusbar
 
  Notes
 
    The default StatusBar texture will be applied if the UI widget does not have a
    status bar texture or color defined.
 
  Options
 
    .maxOverflow - Defines the maximum amount of overflow past the end of the
                   health bar.
 
  Examples
 
    -- Position and size
    local absorbBar = CreateFrame('StatusBar', nil, self.Health)
    absorbBar:SetPoint('TOP')
    absorbBar:SetPoint('BOTTOM')
    absorbBar:SetPoint('LEFT', self.Health:GetStatusBarTexture(), 'RIGHT')
    absorbBar:SetWidth(200)
    absorbBar.maxOverflow = 1.05
 
    -- Register with oUF
    self.TotalAbsorb = absorbBar
 
 
  Hooks
 
  Override(self) - Used to completely override the internal update function.
                   Removing the table key entry will make the element fall-back
                   to its internal function again.
]]
 
local _, ns = ...
local oUF = ns.oUF
 
local function Update(self, event, unit)
  if(self.unit ~= unit) then return end
 
  local ta = self.TotalAbsorb
  if(ta.PreUpdate) then ta:PreUpdate(unit) end
 
  local allAbsorbs = UnitGetTotalAbsorbs(unit) or 0
  local health, maxHealth = UnitHealth(unit), UnitHealthMax(unit)
 
  if(health + allAbsorbs > maxHealth * ta.maxOverflow) then
    allAbsorbs = maxHealth * ta.maxOverflow - health
  end
 
  ta:SetMinMaxValues(0, maxHealth)
  ta:SetValue(allAbsorbs)
  ta:Show()
 
  if(ta.PostUpdate) then
    return ta:PostUpdate(unit)
  end
end
 
local function Path(self, ...)
  return (self.TotalAbsorb.Override or Update) (self, ...)
end
 
local ForceUpdate = function(element)
  return Path(element.__owner, 'ForceUpdate', element.__owner.unit)
end
 
local function Enable(self)
  local ta = self.TotalAbsorb
  if(ta) then
    ta.__owner = self
    ta.ForceUpdate = ForceUpdate
 
    self:RegisterEvent('UNIT_ABSORB_AMOUNT_CHANGED', Path)
    self:RegisterEvent('UNIT_MAXHEALTH', Path)
    self:RegisterEvent('UNIT_HEALTH', Path)
 
    if(not ta.maxOverflow) then
      ta.maxOverflow = 1.05
    end
 
    if(ta and ta:IsObjectType'StatusBar' and not ta:GetStatusBarTexture()) then
      ta:SetStatusBarTexture([[Interface\TargetingFrame\UI-StatusBar]])
    end
 
    return true
  end
end
 
local function Disable(self)
  local ta = self.TotalAbsorb
  if(ta) then
    self:UnregisterEvent('UNIT_ABSORB_AMOUNT_CHANGED', Path)
    self:UnregisterEvent('UNIT_MAXHEALTH', Path)
    self:UnregisterEvent('UNIT_HEALTH', Path)
  end
end
 
oUF:AddElement('TotalAbsorb', Path, Enable, Disable)

spawn

-- Bar
    local absorbBar = CreateFrame('StatusBar', nil, self.Health)
    absorbBar:SetPoint('TOP')
    absorbBar:SetPoint('BOTTOM')
    absorbBar:SetPoint('LEFT', self.Health:GetStatusBarTexture(), 'RIGHT')
    absorbBar:SetWidth(self.Health:GetWidth())
    absorbBar.maxOverflow = 1.05
 
    -- Register with oUF
    self.TotalAbsorb = absorbBar

*edit*

I tested the element. It is working properly. Added it to my layout.

Good job, I think this should be part of oUF, too.




Btw, in case anyone wants a text (tag) based solution:

oUF.Tags.Methods['Absorb'] = function(unit)
	local absorb = UnitGetTotalAbsorbs(unit) or 0
	if absorb == 0 then
		return ' '
	else
		return "|CFFE8E35F"..absorb.."|r"				
	end
end
oUF.Tags.Events['Absorb'] = 'UNIT_ABSORB_AMOUNT_CHANGED'

This will also work for various units (using it on my raid/party frames) and output it as a number. You can also change the text color (E8E35F) by using hexcolor codes.

I'm formatting the value to display something like 117123 as 117k, instead. But left that part of the code out for simplicity reasons. Just mentioning it to show that it's easily possible to clean up the output.

It's already done: https://github.com/haste/oUF/pull/176 But it's rather a rework of the heal prediction element as the default ui anchors heal pred to the health bar texture and the absorbs to the heal pred texture. Also same events are used. The problem is that it is an api breakage, so it won't be included in the 1.6 branch. The use of the same code (with some really minor diffences) from a layout can be seen here. Adding the element is here.
