Help with creating a health tag.

[Wimpface]

So, I've been unable to find any help regarding this for the last few days and I've not found it in any layout so far to take references from.

What I want is a tag that changes color (from green to red) based on the units health, I've tried a bit with oUF.ColorGradient but it has not worked out well for me. (i.e I've done something wrong.)

If anyone would be just as so kind to help me out with this, I'd appreciate it a lot.

Regards,
Rhiren.

oUF_Freeb uses ColorGradient and you can glance at it here if it helps.

Thanks, can't believe I overlooked it.

Also, don't get confused in my updateHealth function. There are 2 different ColorGradients, r,g,b applies to text and x,y,z to the health bar.

EDIT: I added "self" into the function, and now I get a different error. I'll paste the code/error below here.

oUF.Tags['[rhealth]'] = function(self, unit)
	local min, max = UnitHealth(unit), UnitHealthMax(unit)
	
	local status = not UnitIsConnected(unit) and 'Offline' or UnitIsGhost(unit) and 'Ghost' or UnitIsDead(unit) and 'Dead'
	if(max ~= 0) then
		r, g, b = self.ColorGradient(min/max, .69,.31,.31, .65,.63,.35, .33,.59,.33)
	end
	
	return status and status or min ~= max and ('%s'):format(shortVal(min), shortVal(max)) or max
end

oUF.TagEvents['[rhealth]'] = 'UNIT_HEALTH'

change self to oUF.ColorGradient

Edit: your return status needs some work, but I don't know a fix off the top of my head. *sleepy*

Cheers, however, it does not seem to do any coloring at all now but I don't get any errors. Could it be that I'm using a "short value" function?

oUF.Tags['[rhealth]'] = function(unit)
	local min, max = UnitHealth(unit), UnitHealthMax(unit)
	
	local status = not UnitIsConnected(unit) and 'Offline' or UnitIsGhost(unit) and 'Ghost' or UnitIsDead(unit) and 'Dead'
	if(max ~= 0) then

	return status and status or min ~= max and ('%s'):format(shortVal(min), shortVal(max)) or max
end
