How can I make a timer?

Help and Feedback Scripting Support
#1

I currently have a script that counts down from ten minutes (60 * 10 seconds) and displays it on the client’s screen (like a timer) however, this shows the time in seconds, and not minutes then seconds. Is there any way so instead of the timer showing 600 seconds (10 minutes), it will instead show something like 10:00?

How would I go about doing something like that?

Hey there!
Lets say the remaining time (in seconds) is local remainingTime and the string, that will be placed as a text onto your TextLabel will be local text. The code will look something like this:

local minutes = math.floor(remainingTime/60)
local seconds = remainingTime - (minutes * 60)
if #seconds < 2 then
    seconds = "0"..tostring(seconds)
end
local text = tostring(minutes)..":"..tostring(seconds)

I hope you get the point of this code, all you need to do is just to put the code into your while loop and set Text of your TextLabel to text.

An even better solution would be to use some format specifiers.

local function digital_format(seconds)
    return string.format("%d:%02d", math.floor(seconds/60), seconds%60)
end

for i = 600, 0, -1 do
    print(digital_format(i))
    wait(1)
end

%d means digit, whereas %02d means if the number is not 2 digits long, then a 0 will be added to the beginning, which accounts for the seconds being 0-9. So it will look like 5:09 and not 5:9 or something.

I hate to necrobump topics, but is there any way to add hours to this? So I can do something like this: 24:00:00.

It kinda works, except the minutes are outrageously big:

I fixed my equation. the hours were being converted by 24 rather than 60

I did:

local remainingTime = 86401
while true do
	wait(1)
	remainingTime = remainingTime - 1
	local minutes = math.floor(remainingTime / 60)
	local hours = math.floor(minutes / 60)
	local seconds = remainingTime - (minutes * 60)
	if string.len(seconds) < 2 then
		seconds = "0"..tostring(seconds)
	end
	
	if string.len(minutes) < 2 then
		minutes = "0"..tostring(minutes)
	end
	
	local text = tostring(hours)..":"..tostring(minutes)..":"..tostring(seconds)
	print(text)	
end

The minutes are huge (Specifically: 1440 ). They should not be more than 59.

Yeah, i was beginning to spend hours doing calculations on how to get a hour in a fraction and drove myself insane. too tired.
Here’s a workaround using incapz method

local Goal = os.time() + 86400 --24 hours

function HoursConversion(tim)
	return("%02i:%02i:%02i"):format(tim/3600, tim/60%60, tim%60)
end

is tim the seconds remaining???

“tim” would be Goal - os.time()

I quickly threw this script together - basically for the hours it does division, for the minutes it gets the remainder of seconds in an hour and divide by 60 minutes, and lastly for the seconds it gets the remainder of the hour and the minutes.

local Time = math.random(60 * 60, 60 * 135); -- Generate a random number between 3600 (1 hour) and 8100 (2 hours 15 minutes)
print("Time in seconds:", Time);

local Hours = math.floor(Time / 3600); -- Divide by 3600 (number of seconds in an hour)
local Minutes = math.floor((Time % 3600) / 60); -- Get the remainder of 3600, then divide by 60 (number of minutes in an hour)
local Seconds = math.floor((Time % 3600) % 60); -- Lastly get the remainder of 3600, then get the remainder from that (60 being the number of seconds in a minute)

print(string.format("Hours: %d\nMinutes: %d\nSeconds: %d",
	Hours, Minutes, Seconds));

--[[
Time in seconds: W
Hours: X
Minutes: Y
Seconds: Z
--]]

I hope this helped. :slight_smile:
