  • Examples included to demo creating light sources.
  • A single script that you can add code into that will fire off at beginning of the hour/day/week/month/year.
  • Included manual describes the system and it's functions and variables.
  • Easily pause the complete system for dialog scenes.

Using included functions you can easily:

  • Save and load the time to quickly switch between different times.

Light system dosent work

When i place it in the planet room i notice no change in the day/night engine the lighting system dosen't work.

Now this is strange because it was working on a old version of my project i don't know what happened.

Love it! Can easily sync with delta time.

This is such a great and well commented asset! Time plays an important role in my project so I'm building a lot of systems around it. If anyone needs this to work with delta time here's a quick fix:

* in fun_cycleCreateLists: cycleFullDay = cycleLength;
* in scr_timeCycle_step:
curSec += round(cycleSeconds/cycleFullDay) *; //Replace with whatever variable you're using for delta
global.curSec = round(curSec); //Rounding because delta adds a decimal
* in config_timeCycle: cycleLength now represents seconds instead of minutes, so if you want the cycle to last 20 minutes it should be set to 1200.

Thanks for the review Max!

I did just update the asset with a change to the lighting surface to keep it matched to the objects. If you plan on using the lighting surface go ahead and update to the latest version when you can!

Thanks again.

Great, but bugged

Great with day and night, but the fire pit light sources: 1, are not centered on the fire, and 2, follow the view. please help!

Hello Christian and thanks for trying out this asset.

I was able to recreate the issue with the light source moving oddly with the views and I have some solutions for you to use until I update the asset in the next day or so.
Please feel free to message me with the above Contact Publisher button or here -- >

Hello again Christian, I updated the drawing method of the surface so there are no issues with the lights moving oddly. If you have any further questions please feel to message me on the forum.
If the issue you were having is fixed and you feel inclined please update your rating to reflect the changes.

Thanks again for your message!

I've been looking for something like this for a long time, but i couldn't find anything until now. This is way more than a day-night cycle, you can use it to plan virtually anything. And the documentation is very well done. Loving it! :)
