Building

Every building piece has a stability that is passed from the ground up and sideways. The hammer shows it with color: blue is support on the ground, green and yellow are solid, orange and red are at the limit.

Wood holds load worse than stone, and iron beams hold it best and over the greatest distance. Red means a piece is close to its support limit: a piece built onto it will usually collapse unless it gets other support.

Horizontal pieces lose stability faster than vertical ones, so tall buildings stand on pillars. Pieces and stations are in the “Buildings” section.

A piece under a roof does not decay from rain, and a player under a roof does not get wet. A workbench needs a roof over it, otherwise it does not work.

Pieces without a roof or shield over them lose 5% of their health per minute of rain, down to 50%; this does not affect structural support. Most wooden and iron-reinforced pieces (iron beams, iron walls) are affected, while stone, marble and dark wood or ashwood walls and roofs mostly are not. Check the individual piece.

Shelter is checked point by point: a single hole in the roof is enough for the piece under it to start getting wet.

A fire indoors produces smoke that accumulates under the ceiling. If there is too much smoke, the player starts to cough and lose health.

Smoke leaves through an opening in the roof or a chimney. The higher the ceiling, the longer it takes to accumulate.

A fire in the open air causes no smoke problems.

Certain pieces mark a place as the player’s base: a workbench, a hearth, a bed and other stations. Enemies do not spawn near them.

That is why workbenches are placed around the perimeter of a plot: they stop enemies from spawning around it.

Raids can come to the base only if there are enough base pieces nearby.
