Help with Countdown GUI (possibly using delta timer)

[r0uge]

Hey, I would like to make my GUI show a countdown for the "INNOCENTS HAVE UNTIL 4:00 TO HIDE" instead of just a set string - i.e. "INNOCENTS HAVE " .. time_left .. " LEFT TO HIDE".
However, I don't know how to do this. Could anyone help me?
Here is the function I have currently below:

funrounds[2] = function()
    local function BeginRound()
      if CLIENT then
        local showtext = true
        hook.Add("HUDPaint","FUNROUNDMESSAGE",function()
          surface.SetDrawColor(0,0,0,255)
          if LocalPlayer():GetRole() == ROLE_TRAITOR then
            surface.DrawRect(0,0,surface.ScreenWidth(),surface.ScreenHeight())
          end
          if showtext then
            surface.SetFont("Bebas70Font")
            local w = surface.GetTextSize("FUN ROUND")
            surface.SetTextPos(surface.ScreenWidth()*0.5 - w/2, surface.ScreenHeight()*0.3)
            surface.SetTextColor( math.sin(2 * RealTime()) * 127 + 128,math.sin(2 *RealTime()+2) * 127 + 128, math.sin(2 *RealTime()+4) * 127 + 128, 255 )
            surface.DrawText("FUN ROUND")
            local w,h = surface.GetTextSize("HIDE AND SEEK - INNOCENTS HAVE UNTIL 4:00 TO HIDE")
            surface.SetTextPos(surface.ScreenWidth()*0.5 - w/2, surface.ScreenHeight()*0.3+h+5)       
            surface.DrawText("HIDE AND SEEK - INNOCENTS HAVE UNTIL 4:00 TO HIDE")
          end
          timer.Simple(60,function() showtext = false end)
          timer.Simple(60,function() hook.Remove("HUDPaint","FUNROUNDMESSAGE")
            hook.Add("HUDPaint","FUNROUNDNOTIF",function()
              surface.SetFont("Bebas30Font")           
              surface.SetTextPos(5, 5)
              surface.SetTextColor( math.sin(2 * RealTime()) * 127 + 128,math.sin(2 *RealTime()+2) * 127 + 128, math.sin(2 *RealTime()+4) * 127 + 128, 255 )
              surface.DrawText("FUN ROUND")
              local _,h = surface.GetTextSize("HIDE AND SEEK")
              surface.SetTextPos(5, 5+h)       
              surface.DrawText("HIDE AND SEEK")
            end)
          end)
        end)
      else
        tnum = tostring(math.floor(#player.GetAll() / 8)+1)
        game.ConsoleCommand("ttt_traitor_max "..tnum.."\n")
        game.ConsoleCommand("ttt_detective_max 0\n")
        for _,entity in ipairs(ents.GetAll()) do
          if entity:IsWeapon() then
            entity:Remove()
          end
        end
        for _,ply in pairs(player.GetAll()) do
          if ply:GetRole() == ROLE_TRAITOR then             
            game.ConsoleCommand("ulx freeze "..ply:GetName().."\n")                     
            timer.Simple(60,function()
              game.ConsoleCommand("ulx unfreeze "..ply:GetName().."\n")
              game.ConsoleCommand("ulx god "..ply:GetName().."\n")
              ply:SetRunSpeed(600)  
            end)
          end
        end
      end
      hook.Add("Think","FUNROUND_THINK",function()
        if CLIENT then
         
        else
          for _,ply in pairs(player.GetAll()) do
            if not(ply:IsGhost() or not ply:Alive()) then
              if (ply:GetRole() == ROLE_TRAITOR) then
                ply:Give("weapon_ttt_knife")
                for _,knife in pairs(ply:GetWeapons()) do
                  knife.SecondaryAttack = function(self)
                    return
                  end
                  knife.AllowDrop = false
                end
              end
            end
            ply:SetCredits(0)
          end
        end
      end)
    end
    
    local function EndRound()
      if SERVER then
        game.ConsoleCommand("ttt_traitor_max 32\n")
        game.ConsoleCommand("ttt_detective_max 32\n")
        hook.Remove("Think","FUNROUND_THINK")

            game.ConsoleCommand("ulx ungod "..ply:GetName().."\n")
            ply:SetRunSpeed(500)
          end
        end
      else
        hook.Remove("HUDPaint","FUNROUNDMESSAGE")
        hook.Remove("HUDPaint","FUNROUNDNOTIF")
      end
    end
    
    hook.Add("TTTBeginRound","BEGINFUNROUND",BeginRound)
    hook.Add("TTTEndRound","ENDFUNROUND",EndRound)
  end

Assuming [i]time_left[/i] will be a number of seconds left and that you are looking to get the real OS time, you can do something like this:

"INNOCENTS HAVE UNTIL" .. os.date( "%H:%M:%S", os.time() + time_left ) .. "TO HIDE"

You can remove the ":%S" part of the format specifier if you don't want the seconds.

I don't think you understand what I mean. I wanted it to be a countdown from 60 seconds that changes the text every second.

Oh, right. You can use:

local key = HasteMode() && "ttt_haste_end" || "ttt_round_end"
local time_left = string.FormattedTime( math.max( 0, GetGlobalFloat( key, 0 ) - CurTime() ), "%02i:%02i" )

You can then draw the text as follows:

local text = "INNOCENTS HAVE " .. time_left .. " LEFT TO HIDE"
local w,h = surface.GetTextSize(text)
surface.SetTextPos(surface.ScreenWidth()*0.5 - w/2, surface.ScreenHeight()*0.3+h+5)       
surface.DrawText(text)

Countdown example: [url]https://dl.dropboxusercontent.com/u/26074909/tutoring/hud/sh_hud_countdown.lua.html[/url] - This calls a hook on client when count-down is up, same with server. It has some config options, it networks from server to client... Example Start and ExampleNetwork are examples of how to run it, the concommand will start it too.

Basically, you only need to network the start CurTime( ) and the duration. CurTime is synced to clients so with those 2 values you'll be able to easily calculate time remaining to hide..

Thanks for your responses, I ended up doing it a different way but yeah.
