Twine Version: 2
Story Format: Harlow3
Hi all,
I would like to display different passage according to the current time of day.
I know how to display (current-time : ) but I don’t know how to use “if” condition to detect if it is the morning, afternoon or evening.
Thank you in advance for your tips

Welcome Tharmine,
If you use a variable to track time you can call for a passage in a hook.
For instance, given a variable named $period:
(if:$period is "afternoon")[(display: "afternoon")]
If you track time more precisely, you’d like to use a numeric variable, going from 0 to 23, or even from 0 to 1439 if you happen to like to track to the minute.
For instance, given $hour:
(if:$hour >12 and $hour< 19)[(display: "afternoon")]
Hi, thank you for your help.
I want to use the “real” time of the player (as from his pc).
I can get it by using (current-time) but I don’t know what to do with the result (because it does not return just a number apparently).
It does return something like “1:50 PM”, and I don’t know how to use an IF function with > or < to determine if it is before or after a specific time.
Thank you
I assume you use the (current-time:) macro.
Edit: rewritten because of edit error.
Yes I do
Great. Here’s a tentative code:
{
(set: $time to (current-time:))
(if: (str: $time)'s length < 8)[(set: $time to "0" + it)]
(set: _a to (number:(substring: $time,1,2)))
(if: (substring: $time,7,7) is "P")[(set: _a to it+12)]
(if: _a < 7)[(display: "night")]
(elseif: _a < 13)[(display: "morning")]
(elseif: _a < 18)[(display: "afternoon")]
(elseif: _a < 22)[(display: "evening")]
(else:) [(display: "night")]
}
First, I add a ‘0’ if hours is before 10.
Second I make the two first characters a numeric variable.
Third I add 12 if it’s after noon.
Then it’s a simple (if:) ... (elseif:) ... (else:) statement.
Be aware I’m not sure how hours from midnight to one and from noon to one are displayed by a computer, as I live in a country where we usually write hours under the 00:00 to 23:59 form, so you may have to tweek my code a little because of these hours.
Edit: I probably should have use _time instead of $time. The less story variables, the better.
wow, thank you.
We also write time like you, so should not be a problem.
I will test this, thank you very much for your help, reading your script make it more understandable for me.
After research I’m convinced there’s no such thing as 0:45 am nor 0:45 pm, so here’s the last tweak:
{
(set: $time to (current-time:))
(if: (str: $time)'s length < 8)[(set: $time to "0" + it)]
(set: _a to (number:(substring: $time,1,2)))
(if: (substring: $time,7,7) is "P")[(set: _a to it+12)]
(if: _a is 12)[(set: _a to 0)]
(if: _a is 24)[(set: _a to 12)]
(if: _a < 7)[(display: "night")]
(elseif: _a < 13)[(display: "morning")]
(elseif: _a < 18)[(display: "afternoon")]
(elseif: _a < 22)[(display: "evening")]
(else:) [(display: "night")]
}
I’ve added two checks to ensure the hours after midnight and noon are considered as 00 and 12 instead of 12 and 24.
Thanks, your code yesterday worked perfectly already.
But if this one is better I’ll take it 
Thank you again for your help
My code of yesterday would not have worked for a player playing between 00:00 and 00:59, nor between 12:00 and 12:59 because the computer doesn’t write time with 00:xx but 12:xx.
You can easily check that by changing your computer’s timezone, something I didn’t think of yesterday.
Thank, I did change my clock but did not test every possibilities. Encore merci !
