how can I add this function to my lua script?

script_name("HPbar")
script_description("example of using drawBar function")
script_version_number(1)
script_version("v.001")
script_authors("hnnssy")

function main()
if not isSampfuncsLoaded() or not isSampLoaded() then return end
while not isSampAvailable() do wait(100) end
local font = renderCreateFont("Arial", 8, 5)
while true do
wait(0)
if not isPauseMenuActive() and isPlayerPlaying(playerHandle) then
local HP = getCharHealth(playerPed)
local playerposX, playerposY, playerposZ = getCharCoordinates(playerPed)
local screenX, screenY = convert3DCoordsToScreen(playerposX, playerposY, playerposZ)
drawBar(screenX - 50, screenY, 100, 20, 0xBFDF0101, 0xBF610B0B, 2, font, HP)
end
end
end

function drawBar(posX, posY, sizeX, sizeY, color1, color2, borderThickness, font, value)
renderDrawBoxWithBorder(posX, posY, sizeX, sizeY, color2, borderThickness, 0xFF000000)
renderDrawBox(posX + borderThickness, posY + borderThickness, sizeX / 100 * value - (borderThickness * 2), sizeY - (2 * borderThickness), color1)
local textLength = renderGetFontDrawTextLength(font, tostring(value))
local textHeight = renderGetFontDrawHeight(font)
renderFontDrawText(font, tostring(value), posX + (sizeX / 2) - (textLenght / 2), posY + (sizeY / 2) - (textHeight / 2), 0xFFFFFFFF)
end

not sure that i understood you correctly.
first of all, you need to add drawBar function to your script

function drawBar(posX, posY, sizeX, sizeY, color1, color2, borderThickness, font, value)
    renderDrawBoxWithBorder(posX, posY, sizeX, sizeY, color2, borderThickness, 0xFF000000)
    renderDrawBox(posX + borderThickness, posY + borderThickness, sizeX / 100 * value - (borderThickness * 2), sizeY - (2 * borderThickness), color1)
    local textLength = renderGetFontDrawTextLength(font, tostring(value))
    local textHeight = renderGetFontDrawHeight(font)
    renderFontDrawText(font, tostring(value), posX + (sizeX / 2) - (textLenght / 2), posY + (sizeY / 2) - (textHeight / 2), 0xFFFFFFFF)
end

and after that you should use drawBar function (call it) in a loop when you want to show this bar.
this function draws bar for 1 frame, so you should call it every frame in a loop until you want to hide bar.
is it clear?
