Issues with time converting

Help and Feedback Scripting Support
#1

Hello scripters, I am working on my temp ban system and I am trying to convert the time to show how long is left on the user’s ban. I am having some issues with it.

My error:
“ReplicatedStorage.Common.Commands:96: attempt to perform arithmetic (add) on number and nil”


-- My time converting that I use to set my ban time happened(what time the user got banned)

function convertTime(time)
    local day = 86400
    local hour = 3600
    local minute = 60
    
    local lengthNumber = tonumber(string.match(time, "%d+"))

    local time = string.lower(time)
    if string.find(time, "s") then
        seconds = lengthNumber * 1
    elseif string.find(time, "m") then
        seconds = lengthNumber * minute
    elseif string.find(time, "h") then
        seconds = lengthNumber * hour
    elseif string.find(time, "d") then
        seconds = lengthNumber * day
    end

    print("Convert time")
    return seconds
end

-- The time converter I use to check how long is left on the ban

function Format(Int)
	return string.format("%02i", Int)
end

function convertToHMS(Seconds)
    local day = 86400
    local hour = 3600
    local minute = 60

   
	local Minutes = (Seconds - Seconds%60)/60
    Seconds = Seconds - Minutes*60
    local Hours = (Minutes - Minutes%60)/60
    Minutes = Minutes - Hours*60
    print(Minutes, Seconds, Hours)
	return Format(math.abs(Hours)).."h"..Format(math.abs(Minutes)).."m"..Format(math.abs(Seconds)).."s"
end

and here is the code I am trying to execute but errors.


playerProfile.Data.BanTimeHappened = os.time()
playerProfile.Data.BanTime = convertTime(time)
local banTimeInFormat = convertToHMS(playerProfile.Data.BanTimeHappened + playerProfile.Data.BanTime - os.time())
print(tonumber(convertTime(os.time() - (playerProfile.Data.BanTimeHappened + playerProfile.Data.BanTime))))

Which part of the script does it error in?

#3

Right here, with my function not sure why.

#4

You should see an error message in console with a little more information.

#5

This is all there is in the output for errors.

#6

convertToHMS(playerProfile.Data.BanTimeHappened + playerProfile.Data.BanTime

One of these is a number value the other is nil according to that error.

I am aware but I can’t seem to find out why. I think it is my time converting

Print both values, determine which is nil and which isn’t.

BanTime appears to be the one to error any ideas?

#10 
playerProfile.Data.BanTime = convertTime(time)

Something going wrong here then, check the function over.

#11

Errors messages for operations in Luau are non-commutative so it’s easy to find out which data type is which. The first operand is a “number” and the second operand is “nil”.

To OP: What is the value of the variable time in convertTime(time)? It looks like the convertTime function returns nil.

#12

Also avoid using time as a variable, it’s getting flagged as reserved.

The time variable is the input text the user puts example: “1d” which my convertTime function is suppose to change to seconds

#14

You to need to wrap it inside a call to “tonumber()” so that its type is correctly changed before performing any arithmetic operations on it.

#15

Where? In the convert function I need it to be a string

#16

What type of format does the value “time” typically use? Would help out a lot.

print(time)
print(asda)

I know you’re overriding time but you should still avoid using time. And let me know what format “time” is in when its being passed to the function.

#18

So it takes like “1d” and will split the string looking for the number, if it is d then it does the amount of seconds in a day (86400) times the number provided, then returns it in seconds

#19

Yeah, try a print on seconds before it’s returned.

#20 
function convertTime(time)
	local day = 86400
	local hour = 3600
	local minute = 60
	local seconds = 1
	local lengthNumber = tonumber(string.match(time, "%d+"))

	local time = string.lower(time)
	if string.find(time, "s") then
		seconds = lengthNumber * 1
	elseif string.find(time, "m") then
		seconds = lengthNumber * minute
	elseif string.find(time, "h") then
		seconds = lengthNumber * hour
	elseif string.find(time, "d") then
		seconds = lengthNumber * day
	end

	print("Convert time")
	return seconds
end

print(convertTime("25d"))

The function is working for me actually.
