How would I make a decal change every week

[Rynappel]

So I want to make a timer which still goes on when players leave the game, and I want it to wait 1 week and then update a decal on a part. I would assume I would have to use something like os.time()?

PS: This is for a weekly fan art type of thing

[Xx_FROSTBITExX (The123)]

function changedecal() -- Whatever function you want to name it
-- Change decal
end

wait(604800 - os.time()%604800)
changedecal()
while wait(604800) do
changedecal()
end

I think this should work fine. 604800 is equal to one week in secs. And yeh, your on the right track. You going to need to use os.time

[Rynappel]

Thanks so much, would this work even if the player isn’t in the server/

[Ulxqra]

Is this play time or real time?

[Rynappel]

It’s real time, I want it to change every week even when the player isn’t in the server.

What’s the modulus for? Why do you have to return teh remainder? I’m confused.

[Ulxqra]

No, I mean: This script right now: Would not run real time.

[FerbZides]

this wouldnt run when the server ends so the server would still have to run for a week for this manner to change the decal

[Xx_FROSTBITExX (The123)]

@FerbZides OP never specified he wanted it to run it synchronised on the server.
@Ulxqra os.time returns the clients time, so it returns the real life time from the client’s machine
@xxIamInevitable I didn’t return the remainder? I’m subtracting the clients time until a week has passed and calling that function

If you want it to run it on the server and not have it reset, your best bet is grab an arbitrary date that’s valid to calculate the time from.

It’s a bit confusing but I suggest you do some research, here are few links:

Os.time week countdown

I have a leaderboard that shows weekly stats. Assuming that I am getting the current week with os.time, is there a way I could have a “countdown” until a new week begins so players would know when the board will reset. (Of course, then it would start to countdown again at the start of a new week) I know how to display it onto a UI, but how would I take care of the scripting end of things. Thanks

Scripting Weekly Leaderboards

To expand upon what others have already mentioned, it might be better to make leaderboards that last up to the end of the week. That way you can do things such as weekly prizes. To make weekly leaderboards, you would first need to figure out what week you’re in, which you can do with os.time() local WEEK_LENGTH = 60*60*24*7 -- week length in seconds local WEEK_NUMBER = math.floor(os.time()/WEEK_LENGTH) -- current week as a number Now that you know your week number, you can make an OrderedDataS…

Os.time returns what system time?

Yeah, that will return the time in UTC, which will be the same regardless of what timezone the client or the server are in. In order to implement your usecase of expiring Twitter codes, you can use this: local timeValue = os.time({ year = 2019, month = 5, -- May day = 5, hour = 13, minute = 16 }) to get the time value for when it will expire. Note that the time values passed into this function are in UTC. Then, you can just use os.time() < timeValue to tell whether the cod…

The percentage is called ‘modulus’, which is basically division, but it instead returns the remainder.

wait(604800 - ostime()%604800)

[Ty_Scripts (IAmTrulyGreg)]

I think this will work:

while true do
       if os.time("%A") == "43" then
           decalweek43.Parent = display
       elseif os.time("%A") == "44" then
           decalweek44.Parent = display
       end
       wait(0.1)
end
