I recently needed a countdown timer for a game I wanted to port but wasn't able to find a tutorial online. The code wasn't exactly difficult, but it would have saved me some time, so I figured I would upload the template I made for myself so others could use it.

This will show the timer on screen in total seconds (set to the highest maximum number by default) and in digital clock format (00:00:00).

-- countdown timer
-- by ryanb_dev

-- hours:minutes:seconds
-- max 32767 seconds
-- 9:06:06

function _init()
    timer = {
        text = "",
        hours = 0,
        minutes = 0,
        seconds = 0,
        active = true,
        seconds_left = 32767,
        math_seconds = 0,
    }
    last_time = time()
end

function _update60()    
    if (timer.active) then
        timer_update()
    end
end

function _draw()
    cls()
    //actual seconds
    print(timer.seconds_left)
    //clock format
    print(timer.text)
end

function timer_update()
    timer.text = ""

    timer.seconds_left -= time() - last_time
    timer.math_seconds = timer.seconds_left
    last_time = time()

    timer.hours = flr(timer.math_seconds / 3600)
    timer.math_seconds -= timer.hours * 3600

    timer.minutes = flr(timer.math_seconds / 60)
    timer.seconds = flr(timer.math_seconds % 60)

    timer.text = timer.text.."0"..tostr(timer.hours)..":"

    if timer.minutes < 10 then
        timer.text = timer.text.."0"..tostr(timer.minutes)..":"
    else
        timer.text = timer.text..tostr(timer.minutes)..":"
    end

    if timer.seconds < 10 then
        timer.text = timer.text.."0"..tostr(timer.seconds)
    else
        timer.text = timer.text..tostr(timer.seconds)
    end

    if (timer.seconds_left <= 0) then
        timer.active = false
    end
end
