MiniHealthbar

[Vranx]

This is a very simple mod that shows your health/mana, target health and pet health in bars in the middle of the screen:

It no longer works with the current patch and I haven't seen any oUF huds I can use either. It is a very small mod, can anyone tell me what is wrong with it?

function SetMinihealthbarColor(tex, hp, colorSet)
	local r,g,b;
	if hp > 0.75 then
		r = colorSet[1];
		g = colorSet[2];
		b = colorSet[3];
	elseif hp > 0.5 then
		local f = ((hp - 0.5) * 4);
		r = colorSet[1] * f + colorSet[4] * (1 - f);
		g = colorSet[2] * f + colorSet[5] * (1 - f);
		b = colorSet[3] * f + colorSet[6] * (1 - f);
	elseif hp > 0.25 then
		local f = ((hp - 0.25) * 4);
		r = colorSet[4] * f + colorSet[7] * (1 - f);
		g = colorSet[5] * f + colorSet[8] * (1 - f);
		b = colorSet[6] * f + colorSet[9] * (1 - f);
	else
		r = colorSet[7];
		g = colorSet[8];
		b = colorSet[9];
	end
	tex:SetGradient("VERTICAL", r,g,b, r,g,b);
end

function SetMinihealthbarText(text, value)
	if value > 0.99 then
		text:SetText("--")
	elseif value < 0.01 then
		text:SetText("")
	else
		text:SetText(string.format("%i", value * 100))
	end
end

local function HasNormalPowerLevel()
	local type = UnitPowerType("player");
	if type == 0 then --Mana
		if UnitPower("player") < UnitPowerMax("player") then return false; end
	elseif type == 1 then --Rage
		if UnitPower("player") > 0 then return false; end
	elseif type == 0 then --Energy
		if UnitPower("player") < UnitPowerMax("player") then return false; end
	elseif type == 6 then --Runic Power
		if UnitPower("player") > 0 then return false; end
	end
	return true;
end

local function UpdateBar(name, value, max, colorSet, absNum)
	if absNum == nil then absNum = false; end
	local frame = getglobal(name);
	local tex = getglobal(name .. "Texture");
	local text = getglobal(name .. "Text");
	local per = value / max;
	if value == 0 then
		frame:Hide();
	else
		frame:Show();
		SetMinihealthbarColor(tex, per, colorSet);
		tex:SetHeight(frame:GetHeight() * per);
		if absNum then
			SetMinihealthbarText(text, value/100);
		else
			SetMinihealthbarText(text, per);
		end
	end
end

local AllyColorSet = {0,1,0, 1,1,0, 1,0,0};
local EnemyColorSet = {1,0,0, 1,1,0, 0,1,0};
local PowerColorSets = {
	{0,0,1, 0,0,1, 0,0,1}, --Mana

function UpdateMiniHealthBar()
	if UnitHealth("player") < UnitHealthMax("player") or not HasNormalPowerLevel() then

		MiniHealthbarFrame:Show();
		UpdateBar("MiniHealthbarSelf", UnitHealth("player"), UnitHealthMax("player"), AllyColorSet);

	else
		MiniHealthbarFrame:Hide();
	end
end

function MiniHealthbarFrame_OnEvent()
	UpdateMiniHealthBar();
end

function MiniHealthbarFrame_OnLoad()
	this:RegisterEvent("UNIT_HEALTH"); 
	this:RegisterEvent("UNIT_MANA"); 
	this:RegisterEvent("UNIT_RAGE"); 
	this:RegisterEvent("UNIT_ENERGY");
	this:RegisterEvent("UNIT_RUNIC_POWER");
	this:RegisterEvent("PLAYER_TARGET_CHANGED");
	UpdateMiniHealthBar();
end

Any help would be appreciated.

You seem to have not posted the XML, but it's got the global "this" issue and the UnitPowerType() function has changed.

[Dridzt]

Try this.

Fixed a couple obvious bugs I saw apart from API,
but it won't support alternate powertypes (holy power, soul shards, eclipse etc) without some extra work.

Added hunters at least and should work for the rest like before.

Edit:
Btw now that I have your ear you may want to update the author on Power Auras Classic.
I was developing it for about a year (wow 2.4 to 3)
But it's been at least as long since Smacker has had it with major code changes (basically a rewrite) and features.

[Vranx]

I was hoping all the errors would be in the Lua file.

TYVM Dridzt. I show the holy power, etc on my oUF_Neav frames, this is perfect for just seeing minimal info center screen. Will change the author name tomorrow.
