I was able to build a bed in Terraria and I thought it could allow me to sleep. By clicking on it, instead, I set only the spawn point.
Is it possible sleep in other ways or eventually skip nights (or days)?
The 1.3 version of Terraria has now a solution for you.
This item is the Enchanted Sundial.
It is a furniture that can skip one day/night cycle, by setting the time at 4:30 AM. It will also create a new Angler quest.
It reloads every week of in-game time, and no legit action can hasten the cooldown of the furniture :
-placing multiple sundials ?
-remove and place the sundial again ?
Nope, the sundial’s state is stored in the world’s data, you’ll have to wait a full week of in game time, which is 168 minutes (= 2h48m) before the item gets usable again.
