Sorry for the late reply. To skip night you have to lie down. If you're not lying, you will not skip night. So your animation is actually that option. Enable sleep by lie down animation.

I understood your feature. It is a bit more complex to add option. I need to think how to implement it. I would suggest you leave your player not lying while getting food or taking a poop. If you lie down to restore tiredness, in this update it will get restored to 100% after sleep. So after you're done with food and stuff, get back, and rest or sleep normally.

You see, I made it just Minecraft style. It just worked automatically there without prompting. I liked it.

I just realized, that something is odd in your case :) If you are alone on the server, go to sleep, it would skip night anyway. Even if no one joins the server.

But I probably understand why it needs an option to IMPLICITLY agreee to skip night and still be able to use lying animation.

I will hae to think on some solution to that. The best variant is to make some checkbox, in inventory probably.
