Once a house is determined to be suitable, the player may assign an NPC to it by placing the corresponding NPC flag in it. A generic ' This is not valid housing.' can indicate that the frame is not closed, or that there is no place for the NPC to stand (see below for details). This alert prioritizes walls (both fore and background), then furniture ( door, light source, table, and chair). If it is not suitable, the game will show what the house is lacking. A status message indicating whether the house is suitable or not will be displayed. To check whether a house is suitable for use, press the ⚒ Use / Attack button on the '?' housing query mark and then press again anywhere inside the house. The player can check whether a given house is suitable for NPC use or not, as well as manually appoint a house to a specific NPC. It is accessed by pressing the small house button above the armor slots in the inventory. The housing menu allows managing the placement of NPCs. The requirements for a player-selected Bed to work as a spawn point are similar to those for NPC housing, but weaker players do not need furniture beyond the Bed. NPCs can be moved from these to the player's structures using the housing menu. These can include Floating Island structures, Living Tree treasure rooms, and the structures in the underworld. Once initially found, each will require a suitable house before respawning.Ĭertain naturally-generated structures can serve as houses and may inadvertently attract NPCs if players have placed light sources within them. Similarly, the Guide, Angler, Goblin Tinkerer, Tavernkeep, Mechanic, Stylist, Wizard, Tax Collector, and Golfer will each make their initial appearances regardless of available housing. The Old Man, the Traveling Merchant, and the Skeleton Merchant do not require houses. The Guide will appear upon starting a new world, and if killed, he will require a house in order to respawn. They will also retreat to their houses when it rains and during any event. NPCs generally retreat to their houses at night and remain in them until dawn. The player can check if a structure meets the requirements by using the housing menu's top button, labeled with a question mark ('?'). A structure must meet several requirements in order to function as a house (see details below).

A basic house with the dimensions of 9 (exterior width) × 7 (exterior height).Ī house (or home) is a structure built by the player that town NPCs require in order to spawn, with one house required per NPC.
