v50.15 · v0.47.05 This article is about the current version of DF.Note that some content may still need to be updated. |
| Material properties |
| Defined: Value • Color • Density • Strain at yield • Temperature values |
| Derived: Magma safety • Fire safety |
| Fluids: Depth • Flow • Pressure |
Density is a material property that, along with the volume of the object, affects the weight of an object made from the material.
Density influences weight, and tests show that weight affects how much damage blunt-force weapons do. Additionally, lightweight edged weapons or attacking parts made of certain materials seem to have difficulty piercing tissue layers. Apparently, density in dwarf fortress is in kg/m3. Density also affects fall damage. DF simulates falling by shooting the ground at you, so denser floors do more damage.
