Status bar gradient

[Riraito]

im trying to make a health bar using a status bar, and what im wondering, is there some way to make a status bar thats all green when its at 100%, and all red at 0%, and everything in between would follow the gradient from green to red. (I hope you understand what im trying to say lol)

ehr, you can set the color on a StatusBar via myStatusBar:SetStatusBarColor(r, g, b, a)

So, I guess that if you could figure out the appropriate values of r, g, and b based on your health percentage, you could do that.

HTH,
F.O.R.

Actually, this wouldn't be too hard to do at all.

local f = CreateFrame("Frame", nil, UIParent);
f:RegisterEvent("UNIT_HEALTH");
f:RegisterEvent("PLAYER_ENTERING_WORLD");
f:SetScript("OnEvent", function() DoHealthBarColor() end )

function DoHealthBarColor()
local h = UnitHealth("player") / UnitHealthMax("player")
PlayerFrameHealthBar:SetStatusBarColor(1-h, h, 0, 1);
end

That should work, barring any minor typos.

ah thanks neuro thats just what I was asking,

Edit: nvm im a dumbass lol

That's just the formula for determining color. It's in r, g, b format, so (1-h, h, 0) means that your red goes up as your health goes down (1-h is the inverse of h), and h means your green goes down as your health goes down.

Actually, looking at that code, while it does exactly what you asked it to do, it's not very pretty. A better version might be:

local f = CreateFrame("Frame", nil, UIParent);
f:RegisterEvent("UNIT_HEALTH");
f:RegisterEvent("PLAYER_ENTERING_WORLD");
f:SetScript("OnEvent", function() DoHealthBarColor() end )

function DoHealthBarColor()
local h = UnitHealth("player") / UnitHealthMax("player")
local r,g=math.min(1.5 - (h*1.5),1), math.min(1.5*h, 1);
PlayerFrameHealthBar:SetStatusBarColor(r, g, 0, 1);
end


The formula for determining the color, "local r,g=math.min(1.5 - (h*1.5),1), math.min(1.5*h, 1)", is a bit prettier.

lol about my second post, I was gonna ask what does 1-h mean because I thought it was a dash, then I realised it was a minus symbol so I figured it out, now im wondering, what makes the second one you posted better? I would have thought the first one was better because itsshorter and looks cleaner imo, but I trust your judgement better lol
