Hello everybody, I am trying to create a mod where you can find werewolves on the wild but I want them to appear just during the night, maybe from 22.00 p.m untill 06.00 a.m. How can I do this, please? Thank you very much in advance.

I believe you can make an alias on your quest, using 'Create Reference to Object' (enter 'MyWherewolf' as the object) + 'at' 'Player'
You will need to make an alias to the player first, to use the 'at player' part.

Then in the alias conditions use 'GetCurrentTime' to make sure the alias is only created at night

I believe that will work. Keep in mind though there are probably several different ways of doing this. Which way you want really depends on what your trying to accomplish
