oUF Absorb bar

[sticklord]

Hello!

I've got a problem with oUF that i just can't get my head around. Basically its a absorb bar that goes from 0-100% of a units hp, anchored to the health. It's mostly working fine, but if the unit have an absorb on itself when the unitframe is first viewed after a login, it maxes out. If i have opened the unitframe before they get an absorb however, it works fine.

Creating the bars:

-- Absorb bar
local TotalAbsorb = CreateFrame('StatusBar', nil, self.Health)
TotalAbsorb:SetStatusBarTexture(config.absorbtexture, "OVERLAY")
TotalAbsorb:SetFrameLevel(self:GetFrameLevel() - 1)
TotalAbsorb:SetStatusBarColor(1,1,1,1)
TotalAbsorb:SetAllPoints(self.Health)
TotalAbsorb:Hide()
 
local spark = TotalAbsorb:CreateTexture(nil, 'ARTWORK', "OverAbsorbGlowTemplate")
spark:SetSize(20,5)
spark:Hide()
TotalAbsorb.spark = spark
 
-- Incoming Heals
local incHeals = ns.CreateStatusBar(self.Health)
incHeals:SetPoint('TOPLEFT', self.Health:GetStatusBarTexture(), 'TOPRIGHT')
incHeals:SetPoint('BOTTOMRIGHT')
incHeals:SetFrameLevel(self:GetFrameLevel() - 1)
incHeals:SetStatusBarColor(0, 1, 0, 0.5)
incHeals:SetFrameStrata('MEDIUM')
incHeals:Hide()
 
-- Absorbing Heals
local necroHeals = ns.CreateStatusBar(self.Health, 'OVERLAY')
necroHeals:SetFrameLevel(self:GetFrameLevel() - 1)
necroHeals:SetStatusBarColor(1, 0, 0, 0.3)
necroHeals:SetReverseFill(true)
necroHeals:SetPoint('TOPLEFT')
necroHeals:SetPoint('BOTTOMRIGHT', self.Health:GetStatusBarTexture(), 'BOTTOMRIGHT')
 
self.HealPrediction = {
    incHeals = incHeals,
    necroHeals = necroHeals,
    TotalAbsorb = TotalAbsorb,
    Override = ns.UpdateIncHeals,
}

And the update function:

function ns.UpdateIncHeals(self, event, unit)
    if (self.unit ~= unit) then return end
    local hp = self.HealPrediction
    local curHP, _, maxHP = self.Health:GetValue(), self.Health:GetMinMaxValues()
    local incHeal = UnitGetIncomingHeals(unit) or 0
    local healAbsorb = UnitGetTotalHealAbsorbs(unit) or 0
 
    if ( healAbsorb > 0) then
        hp.necroHeals:SetMinMaxValues(0, curHP)
        hp.necroHeals:SetValue(math.min(healAbsorb, curHP))
        hp.necroHeals:Show()
    else
        hp.necroHeals:Hide()
    end
 
    if ((incHeal - healAbsorb) <= 0) or (curHP == maxHP) then
        hp.incHeals:Hide()
    else
        hp.incHeals:SetMinMaxValues(0, maxHP - curHP)
        hp.incHeals:SetValue(incHeal - healAbsorb)
        hp.incHeals:Show()
    end
 
    if (hp.TotalAbsorb) then
        local absorb = UnitGetTotalAbsorbs(unit) or 0
        if (absorb == 0) then
            hp.TotalAbsorb.spark:Hide()
            hp.TotalAbsorb:Hide()
        else
            hp.TotalAbsorb:SetMinMaxValues(0, maxHP)
            hp.TotalAbsorb:SetValue(math.min(absorb, maxHP))
            hp.TotalAbsorb:Show()
            hp.TotalAbsorb.spark:ClearAllPoints()
            hp.TotalAbsorb.spark:SetPoint('BOTTOM', hp.TotalAbsorb:GetStatusBarTexture(),'BOTTOMRIGHT', 0, -1)
            hp.TotalAbsorb.spark:Show()
        end
        print(unit, self.unit, absorb,"VALUE:",math.min(absorb, maxHP),"MAXHP", maxHP,"POINTS",hp.TotalAbsorb:GetPoint())
    end
end
