Okay so ive been trying to make a healthbar useing a Ragebar i found in a youtube video. this is the code:

Code:

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
    local player_rage = Unitpower("player", 1)
    local red, green, blue = 0,0,0
    if player_rage > 60 then
         red, green, blue = 0,1,0
    elseif player_rage > 20 then
         red,green,blue = 0,1,1
    else
         red,green,blue = 1,0,0
    return red, green, blue, 1
end

and i tried changeing it to:

Code:

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
    local player_health = health("player", 1)
    local red, green, blue = 0,0,0
    if player_health > 60 then
         red, green, blue = 0,1,0
    elseif player_health > 20 then
         red,green,blue = 0,1,1
    else
         red,green,blue = 1,0,0
    return red, green, blue, 1
end

Any1 could help me make this work?

The second line would need to be:

Code:

local player_health = UnitHealth("player")

so i changed it to.

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
local player_health = UnitHealth("player" )
local red, green, blue = 0,0,0
if player_health > 60 then
red, green, blue = 0,1,0
elseif player_health > 20 then
red,green,blue = 0,1,1
else
red,green,blue = 1,0,0
return red, green, blue, 1
end

yet it gives me the error:

[string " return function(progress, r1, g1, b1, a1, r2, b2, a2)..."]:15: 'end' expected(to close 'function' at line1) near '<eof>'

got any idea what this error means?

Put an 'end' before the return statement.

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
local player_health = UnitHealth("player" )
local red, green, blue = 0,0,0
if player_health > 60 then
red, green, blue = 0,1,0
elseif player_health > 20 then
red,green,blue = 0,1,1
else
red,green,blue = 1,0,0
end
return red, green, blue, 1

like this i guess, gives the error:

[string " return function(progress, r1, g1, b1, a1, r2, b2, a2)..."]:16: 'end' expected(to close 'function' at line1) near '<eof>

does the "if player_health > 60 then" need to be something else? like "if player_health% > 60% then"?

No, you removed the end that closes the function when you added the end to close the if statement..

Lua Code:

function(progress, r1, g1, b1, a1, r2, g2, b2, a2)
    local player_health = UnitHealth("player")
    local red, green, blue = 0,0,0
    if player_health > 60 then
        red, green, blue = 0,1,0
    elseif player_health > 20 then
        red, green, blue = 0,1,1
    else
        red, green, blue = 1,0,0
    end
    return red, green, blue, 1
end

All this function does is return a color code based on how much health you have.
