• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Triggering an animation based the local time of Dusk + a time offset

Hi Folks,

I'm using a simple conditional statement to trigger a fireworks display between 18:30 and 20:00 local time in Alaska.

<UseTemplate Name="Asobo_GT_Update" >
<FREQUENCY>0.2</FREQUENCY>
<UPDATE_CODE>
(E:LOCAL TIME, hour) 18.50 &gt; (E:LOCAL TIME, hour) 20.00 &lt; and
if{ 1 (&gt;Z:TRIGGER_FIREWORKS1) } els{ 0 (&gt;Z:TRIGGER_FIREWORKS1) }
</UPDATE_CODE>
</UseTemplate>

This works fine except as the time of the year changes then evenings become lighter/darker and at the height of the summer it will still be very light at 18:30

Is it possible to recode this trigger statement to use the time of the local Dusk plus say 30 minutes so that the fireworks always trigger after dusk and then run for a few hours so it will be usable all year round?

regards
Kev

Don't think so but you can add a date variable and have up to 365 unique start times. However, I think you can also apply a "year" parameter, so, even more.

With RPN complex formulas can be defined, so either recreating the sunrise-equation (for math geniuses) or, alternatively, using if-else branches per season should be possible. Pseudo code:
// Earliest time at the evening (about +/- 2 months around 21 december):
if LOCAL MONTH OF YEAR >= 11 AND LOCAL MONTH OF YEAR <= 2
-> apply times valid for winter
els if LOCAL MONTH OF YEAR >= 5 AND LOCAL MONTH OF YEAR <= 8
-> apply times valid for summer
els
-> apply times valid for spring and autumn
