Create Text Frame with Player's Health

Hey guys, I have zero knowledge in LUA scripting, however I am trying to know a bit more about it. I want to create a simple text on screen which will show the current player's health.
This is what I've done so far, but got stuck:

Code:

local f = CreateFrame("Frame", nil, UIParent)

        f:SetWidth(1)

        f:SetHeight(1)

        f:SetAlpha(1)

        f:SetPoint("CENTER", 0, 0)

        f.text = f:CreateFontString(nil,"ARTWORK")

        f.text:SetFont("Fonts\\FRIZQT__.TTF", 14, "OUTLINE")

        f.text:SetPoint("CENTER", 0, 0);

From here I don't know where to go, can someone help?

Something simple:

Lua Code:

local function UpdateHealth(self) -- Update the health text
    local health = UnitHealth("player")
    self.Text:SetText(health .. '/' .. self.healthMax)
end
local function UpdateHealthMax(self) -- Update max. health value
    self.healthMax = UnitHealthMax("player")
    UpdateHealth(self)
end
 
local f = CreateFrame("Frame", "nibsrsHealthText", UIParent)
f:SetSize(5, 4)
f:SetPoint("CENTER")
f.Text = f:CreateFontString()
f.Text:SetFontObject(GameFontNormal)
f.Text:SetPoint("CENTER")
f.Text:SetJustifyH("CENTER")
f.Text:SetJustifyV("CENTER")
 
f:SetScript("OnEvent", function(self, event, ...) -- when registered events fire.
    if event == "UNIT_HEALTH" then -- Fired when health changes
        UpdateHealth(self)
    elseif event == "UNIT_MAXHEALTH" then -- Fired when max. health changes
        UpdateHealthMax(self)
    end
end)
f:RegisterEvent("UNIT_HEALTH") -- register the events to be used (when health changes happen)
f:RegisterEvent("UNIT_MAXHEALTH")
UpdateHealthMax(f) -- initialise the health text

Hey, thank you so much! However, the text isn't showing up :( Any clue why?

You're dead? :D

It should be gold text in the middle of your screen even if it's just 0/0.

If you're comming from an initial login rather than a /reload you can change the inital text setting to the PLAYER_LOGIN event.

You can change the "UNIT_HEALTH" to "UNIT_HEALTH_FREQUENT" if your doing this in Classic (leave it as is for BCC).

Lua Code:

local function UpdateHealth(self) -- Update the health text
    local health = UnitHealth("player")
    self.Text:SetText(health .. '/' .. self.healthMax)
end
local function UpdateHealthMax(self) -- Update min./max. health values
    self.healthMax = UnitHealthMax("player")
    UpdateHealth(self)
end
 
local f = CreateFrame("Frame", "nibsrsHealthText", UIParent)
f:SetSize(5, 4)
f:SetPoint("CENTER")
f.Text = f:CreateFontString()
f.Text:SetFontObject(GameFontNormal)
f.Text:SetPoint("CENTER")
f.Text:SetJustifyH("CENTER")
f.Text:SetJustifyV("CENTER")
 
f:SetScript("OnEvent", function(self, event, ...)
    if event == "UNIT_HEALTH" then -- Fired when health changes
        UpdateHealth(self)
    elseif event == "PLAYER_LOGIN" or event == "UNIT_MAXHEALTH" then -- Fired when max. health changes
        UpdateHealthMax(self)
    end
end)
f:RegisterEvent("UNIT_HEALTH") -- register the events to be used
f:RegisterEvent("UNIT_MAXHEALTH")
f:RegisterEvent("PLAYER_LOGIN") -- Fires only once before the "PLAYER_ENTERING_WORLD" event.
