Lockdown HUD

[ErrO]

Soo, I'm making my own hud and I want it to say about lockdown in middle of the screen, what's the function of lockdown like
if lockdown then
draw.SimpleText("Lockdown has started", "Lockdownfont", 0, 0, Color(255,255,255,255), TEXT_ALIGN_CENTER)
end

What do I replace "lockdown" with?

HUD, if you are interested.
