Background Walls are tiles that create backgrounds. Most wall types are items that can exist in player inventories, and can be placed by players in any area that doesn't already have background walls. Walls can be removed with a Hammer. All walls fall under two categories.
- Housing walls are placed by players or generated in certain structures. They prevent enemies from spawning, but do not do anything to prevent their passage, and a mostly unbroken background of housing wall tiles is necessary for a structure to qualify as a House for attracting NPCs, or to place a Bed that can set a player's spawn point.
- Natural walls are instead found throughout the world in several Biomes, and cannot be placed by players. Natural walls will not stop enemies from spawning, and cannot be utilized for Houses. These walls must be removed by starting from their edge (i.e., there must be at least one adjacent tile with no wall), unlike housing walls, which can be removed from any point. Explosives can remove all natural walls within their blast radius as long as an edge is somewhere within the radius.
Certain walls, such as Obsidian Brick Walls or Dungeon Brick Walls exist in both natural and housing forms. With these walls, the player must break the natural walls and replace them in order to allow them to count as housing walls. Furthermore, the natural form of some walls, such as Dirt Walls or Jungle Walls cannot be harvested, and must instead be crafted or purchased from an NPC.
Walls are generally obtained via crafting, purchasing from NPCs, or by harvesting naturally-occurring walls. One item of crafting material generally crafts four of its corresponding Wall items. Most walls can also be crafted back into the items they were made from (four walls to one item), except for any wall crafted from more than one ingredient (e.g., Stained Glass).
Notes[edit | edit source]
- Dirt Walls generally completely cover the background at Underground depths above zero (see Layer, Depth Meter). Placing new walls in this area would require first tearing down the existing walls starting from the top (the Surface) or the bottom (zero depth), which can be an arduous task. Alternatively, the existing walls can be destroyed using Dynamite.
- At depths below zero, the backdrop of the map is generally no longer covered with actual wall tiles, though this can be difficult to differentiate visually since the background image at these depths can have a similar appearance. Walls can be placed freely here by players.
- Torches and several other furniture items can be placed directly on background walls without requiring blocks below them.
- Walls have no coin value, (excluding wallpaper bought from the Painter) even if they were crafted from rare materials.
These walls are made by the player using various crafting materials.
These walls are purchased from various NPCs.
These walls are spawned when the new world is created, and can all be obtained by some method.
These walls are mainly created when the Corruption, Crimson, or Hallow naturally spreads to them, but they can also be made by using the respective Solution with the Clentaminator. When destroyed, these walls do not drop anything. This technically makes them unobtainable.
These walls are spawned when the world is created but are unable to be created, obtained, looted, purchased, or used by the player in any way. They can be destroyed, but drop nothing (with an exception).
- Unobtainable walls can be utilized with third-party map editors such as TEdit.
