How can I make this into minutes and not only seconds?

Help and Feedback Scripting Support
#1

Hello! I am trying to make a stopwatch script go into minutes and not only seconds.

Here is what I have rn:

local timeFormat = "%.3f" 
local tostr = tostring
local format = string.format

game.ReplicatedStorage:WaitForChild("TimeTrials").Changed:Connect(function()
	script.Parent.Label.Text = format(timeFormat, tostr(game.ReplicatedStorage:WaitForChild("TimeTrials").Value))
end)

Output for 1 Minute, 3 seconds, and 3427093 miliseconds:
63.342

What i’m trying to do is this:
1:03.342

If you can help, please let me know. Thanks, WE

you can do some math to convert seconds to minutes, dk the formula check on google

You can use the modular(%) function, as it gives a remainder.

print(63.342 % 60) -- 3.342

So you can get the time by doing:

local Number = 63.342 % 60
print(tostring((63.342 - Number) / 60) .. ":" .. Number) -- 1:3.342

So assuming game.ReplicatedStorage:WaitForChild("TimeTrials") is some sort of numberValue, then you can use the format specifier "%d:%.3f"

local ReplicatedStorage = game:GetService("ReplicatedStorage") -- for ez access
local timeTrials = ReplicatedStorage:WaitForChild("TimeTrials")
local label = script.Parent:WaitForChild("Label")

local TIME_FORMAT = "%d:%.3f"

timeTrials.Changed:Connect(function(new: number) -- ValueBases have a non-inherited Changed event which passes new value
	label.Text = TIME_FORMAT:format(math.floor(new/60), new%60)
end)

since you want to keep the decimal up to the third place, you don’t mod or anything, also obviously dividing by 60 and rounding it down to get the minutes

Yea that works, but the only thing is if seconds is < 9 then, it would show as 0:8.845 and not 0:08.845. Otherwise, that works.

My bad, you do mod by 60, since we are talking about time, I can’t think of a one-liner pattern for this, so I recommend for now just getting the remainder then concatenating it back in :\

So this would make your time format instead be "%d:%02d", so that it pads a zero at the beginning of the seconds, if it is <2 digits

local remainder = new%1
label.Text = TIME_FORMAT:format(math.floor(new/60), new%60)
label.Text ..= string.format("%.3f", remainder)

Were super close. The only problem is this:

1 second, 706 miliseconds

Code:

local TIME_FORMAT = "%d:%02d"

timeTrials.Changed:Connect(function(new: number) -- ValueBases have a non-inherited Changed event which passes new value
	local remainder = new%1
	label.Text = TIME_FORMAT:format(math.floor(new/60), new%60)
	label.Text ..= string.format("%.3f", remainder)
end)

Also it works fine if we remove the miliseconds.

"%d:%.02d"

Missed a period.

Also you can combine the formats :slight_smile:

local secs = 63.342

local function formatTime(seconds)
    return string.format("%d:%.02d.%.03d", seconds/60, seconds%60, seconds*1000%1000)
end

print(formatTime(secs)) -- 1:03.342
