Make a countdown clock?
so there has to be a better way to do this. I got it starting at 10:00 and it goes down to 00:00. That's ten minutes. But, here's my way of counting down and there has to be a faster way, help?
local gametime = script.Parent
while true do
wait(1)
gametime.Text = "09:59"
wait(1)
gametime.Text = "09:58"
wait(1)
gametime.Text = "09:57"
wait(1)
gametime.Text = "09:56"
end
And so on to 00:00

The bare bones of a countdown timer conventionally consist of a 'for' loop running backwards.
gametime = script.Parent
totalsec = 600 -- Because 10 minutes * 60 seconds per minute = 600 seconds
for i = totalsec, 0, -1 do
gametime.Text = i
wait(1)
end
This will only display the amount of seconds left, though - not in MM:SS format.
MM:SS FORMAT:
05:30
NOT MM:SS FORMAT:
330
To do so requires the knowledge of the modulo operator (%). A modulo operation returns the remainder in a division operation.
Example:
11 / 5 = 10 r 1
11 % 5 = 1
So, how do you implement this knowledge into the countdown timer? By:
Assigning more variables (minutes and seconds)
Get the amount of minutes left
Get the amount of seconds left without breaching the 59-second boundary
Stick to the first script if you don't really understand the modulo operator for now.
MODULO OPERATION EXAMPLE
For five minutes, this example will print the time counting up.
totalsec = 300 -- 5 minutes
for i = 0, totalsec do -- timer counts up
local Min = math.floor( i / 60 )
local Sec = i % 60
if Min < 10 then -- If minute is less than 10, add a "0," so: "05" instead of "5."
Min = ("0".. Min)
end
if Sec < 10 then -- If second is less than 10, add a "0," so: "08" instead of "8."
Sec= ("0".. Sec)
end
print(Min .. ":" .. Sec)
wait(1)
end
