reverse status bars (again)

[j3rem1e]

I reopen a really old thread, but with the 7.0 patch, the "ReverseBar" function doesn't work, and I don't have any idea why. Calling "tex:SetPoint" with any parameters doesn't seem to have any effect.

I am using a custom fork of oUF_Mono witch use this function :

local ReverseBar
do
    local UpdaterOnUpdate = function(Updater)
        Updater:Hide()
        local b = Updater:GetParent()
        local tex = b:GetStatusBarTexture()
        tex:ClearAllPoints()
        tex:SetPoint("BOTTOMRIGHT")
        tex:SetPoint("TOPLEFT", b, "TOPRIGHT", (b:GetValue()/select(2,b:GetMinMaxValues())-1)*b:GetWidth(), 0)
    end
    local OnChanged = function(bar)
        bar.Updater:Show()
    end
    function ReverseBar(f)
        local bar = CreateFrame("StatusBar", nil, f)
        bar.Updater = CreateFrame("Frame", nil, bar)
        bar.Updater:Hide()
        bar.Updater:SetScript("OnUpdate", UpdaterOnUpdate)
        bar:SetScript("OnSizeChanged", OnChanged)
        bar:SetScript("OnValueChanged", OnChanged)
        bar:SetScript("OnMinMaxChanged", OnChanged)
        return bar;
    end
end

Using ReverseFill doesn't work either, because of the Smooth plugin : calling SetValue in a PostUpdate callback make the bar going from right to left continually. I'll try to hack this plugin, but this solution doesn't look very good to me.

Any help appreciated, and I apologize for my bad english :-)

Same as j3rem1e.

I have been asking this few months ago and zork tried his best to enlighten me, but I was so stupid to understand his effort...

I was damn busy for last couple of months finishing my work and finally back here to solve this old problem.

Tried with haste's method:

Health:SetReverseFill(true)
Health.PostUpdate = function(Health, unit, min, max)
   Health:SetValue(max - Health:GetValue())
end

as well as Monolit's method which I modified a bit to match my taste:
(BUT, I definitely left a contribution comment!)

A.CreateHealthBar = function(f, unit)
    local Health;
 
    if unit == "player" or unit == "targettarget" then
        Health = CreateFrame("StatusBar", f:GetName() .. "HealthBar", f);
    elseif unit == "target" then
        Health = A.ReverseStatusBar(f);
        Health.PostUpdate = A.PostUpdateHealth;
    end
 
    Health:SetFrameLevel(Health:GetFrameLevel() + 1);
    Health:SetStatusBarTexture(HEALTH_BAR);
    Health:SetStatusBarColor(0.85, 0.86, 0.84, 1);
 
    if unit == "player" then
        Health:SetPoint("TOPRIGHT", f, "TOPRIGHT", -1, -1);
        Health:SetSize(f:GetWidth() - 12, f:GetHeight() - 12);
    elseif unit == "target" then
        Health:SetPoint("TOPLEFT", f, "TOPLEFT", 1, -1);
        Health:SetSize(f:GetWidth() - 12, f:GetHeight() - 12);
    elseif unit == "targettarget" then
        Health:SetPoint("TOP", f, "TOP", 0, -1);
        Health:SetSize(f:GetWidth() - 22, f:GetHeight() - 12);
    end
 
    Health.bg = Health:CreateTexture(nil, "BACKGROUND");
    Health.bg:SetAllPoints(true);
    Health.bg:SetTexture(BACKDROP);
    Health.bg:SetVertexColor(0.08, 0.08, 0.08, 1);
 
    f.Health = Health;
    f.Health.bg = Health.bg;
end
 
-- Thanks to Monolit from WoWInterface for sharing this code!
local StatusBarUpdaterOnUpdate;
local StatusBarOnChanged;
A.ReverseStatusBar = function(f, unit)
    local statusbar = CreateFrame("Statusbar", f:GetName() .. "HealthBar", f);
    statusbar.updater = CreateFrame("Frame", nil, statusbar);
    statusbar.updater:Hide();
    statusbar.updater:SetScript("OnUpdate", StatusBarUpdaterOnUpdate);
 
    statusbar:SetScript("OnSizeChanged", StatusBarOnChanged);
    statusbar:SetScript("OnValueChanged", StatusBarOnChanged);
    statusbar:SetScript("OnMinMaxChanged", StatusBarOnChanged);
 
    return statusbar;
end
 
StatusBarUpdaterOnUpdate = function(updater)
    updater:Hide();
 
    local b = updater:GetParent();
 
    local tex = b:GetStatusBarTexture();
    tex:ClearAllPoints();
    tex:SetPoint("BOTTOMRIGHT");
    tex:SetPoint("TOPLEFT", b, "TOPRIGHT", (b:GetValue() / select(2, b:GetMinMaxValues()) - 1) * b:GetWidth(), 0);
 
    local d = select(2, b:GetMinMaxValues());
 
    local x;
 
    if d ~= 0 then
        x = (b:GetValue() / (d - 1)) * b:GetWidth();
    end
 
    tex:SetPoint("TOPLEFT", b, "TOPRIGHT", x, 0);
end
 
StatusBarOnChanged = function(statusbar)
    statusbar.updater:Show();
end
 
A.PostUpdateHealth = function(statusbar, unit, min, max)
    if UnitIsDeadOrGhost(unit) then
        statusbar:SetValue(0);
    end
end

Unfortunately, those two approaches does not seem to work for me either...

Could we please get some help regarding this?

Thank you!

If this can help you, I have fixed oUF_Mono by using the following function. Probably not the prettiest things to do as I am not an addon coder, but at least, it works and it's compatible with the Smooth plugin :-)

local ReverseBar
  do
	local ReverseSetValue = function(self, value)
		local minv, maxv = self:GetMinMaxValues();
		self.__value = value;
		self:__setValue(maxv - value);
	end
	local ReverseGetValue = function(self)
		return self.__value;
	end
	function ReverseBar(f)
		s = CreateFrame("StatusBar", nil, f) 
		s:SetReverseFill(true)
		s.__setValue = s.SetValue;
		s.SetValue = ReverseSetValue;
		s.__value = s:GetValue();
		s.GetValue = ReverseGetValue;
		return s;
	end
  end

Sweet!

I'll have a go with it

Thank you !!
