So, the thing is I've heard of os.date() but I don't know how to use it.
I looked online but no sources were helpful. Maybe there is another way to get the date.
I'm trying to make a live event, and some code that would check if it is the date of the event. If so, then do event. If not, don't do event.
Thanks!
I'll show an example here of using os.date first. I have some suggestions at the end.
local dateTable = os.date("!*t") -- !*t and *t are magical "format strings". !*t means give me the
-- date in the UTC timezone (basically london's timezone), whereas *t will give the date based
-- on the current systems local timezone, this will refer to the roblox server so it's unclear what
-- that will really mean.
if dateTable["year"] == 2019 and dateTable["month"] = 7 and dateTable["day"] = 4 then
-- happy fourth of july
else
-- not doing the event :(
end
That check will obviously have to go in a loop. If you want something more granular in terms of time (maybe your event lasts only 3 hours) look into the os.date documentation here for what else you can find in the dateTable ... https://developer.roblox.com/en-us/api-reference/lua-docs/os.
What I would end up suggesting instead is that if this is a one-off event then you can compute the timestamp ahead of time (something used in computer science to signify a moment in time by the number of seconds elapsed since the "UNIX Epoch" (https://en.wikipedia.org/wiki/Unix_time)) and then check os.time() against it. os.time() gives you the number of seconds. What I like about this is it becomes much clearer how to do time intervals. For example, say I want a july fourth celebration this year to start at midnight in the UTC timezone and last for 10 hours after that. I went to a website https://www.unixtimestamp.com/ and found out that the timestamp I want it to start at is ... 1562198400 (seconds since the unix epoch).
while true do
if os.time() >= 1562198400 and os.time() <= 1562198400 + 10 * 60 * 60 then
-- party code
else
-- no party code
end
wait()
end
EDIT: An epiphany. We don't actually need to do loops to wait for the right time, we can actually use wait with this last method here ...
local servertime = os.time() -- the initial time
local eventstart = 1562198400 -- what time I want to wait for
local diff = eventstart - servertime
if diff > 0 then -- if it hasn't happened yet
wait(diff) -- no loop needed!
end
print("woop woop")
-- celebrate until diff == -60 * 60 * 10 or soemthing ...

os.date requires one of the two arguments: "!*t" or "*t". This will make the function return a table that can be indexed with many keywords, like "day," "year," "month," "sec," and "hour."
um
