Editing Filth

<!-- Game data for this page can be found in \ThingDefs_Misc\Filth_Various.xml -->
'''Filth''' is a broad term for any of several types of tile effects, all of which possess unique in-game appearances. Most types of filth have negative '''[[beauty]]''' and '''[[cleanliness]]''' stats. Filth does not hinder movement, manipulation, or field of view, and cannot be picked up. Filth is often spontaneous and unpreventable, with potentially disastrous consequences. 

Many colonist tasks are directly impacted by the nearby presence of filth. The cleanliness room stat affects [[food poisoning]], [[room]] quality, [[research speed]], infection chance, and [[surgery]] success chance. 

Filth is also a major factor on your colonists' [[mood]]. Pawns who have been in a filthy, ugly environment too long will gain a negative thought. Filth can quickly destroy the quality rating of an otherwise fine room, too, depriving your colonists of potential positive thoughts.

== Generation ==
Filth is most frequently a problem on '''hard floors''' like [[concrete]], [[wood floor]], or [[rough stone]]. These hard floor-types accumulate dirt from pawns much faster than natural terrain, like soil or sand. Several types of filth may stack on the same tile at the same time, with cumulative beauty effects. 

Some types of filth like '''"foot-traffic"''' dirt and colonists' '''trash''' are passively emitted periodically. An animal's [[Filth Rate]] determines how often it spontaneously produces '''animal filth''' on hard floors. In general, large animals produce a lot of animal filth and should thus be kept off of hard floors using [[zones]]. Smaller animals like the [[husky]] or [[cat]] have filth rates equal to or lower than humans.
[[Straw matting]] can be used to absorb some animal filth, but it is highly flammable.

When a pawn is moving from terrain to floors, there is a chance for a pawn to track filth along their path for some number of tiles.{{Check Tag|Detail needed|What filth, what chance, how many tiles. Also add detail to Floors page}}

== Interactions ==
{{Stub|section=1|reason=Account for floor clean time multi}}
Filth is removed from a tile by colonists assigned to [[Work#Clean|Cleaning]] or by rain if [[Roof|unroofed]]. Only filth in the [[Home area]] will be cleaned; tiles outside the home area will be ignored.

Limiting the home area of your colony will substantially reduce cleaning demands on your colonists. By default, a home area is automatically designated around new player structures and zones (this setting may be toggled in the lower right corner icon bar). However, home area designation is '''''not''''' automatically removed from an area, even if player structures are removed.

All colonists clean tiles at the same rate regardless of [[trait]]s or [[capacities]], but some types of floors, like [[Steel tile]]s and [[sterile tile]]s, are faster to clean than others. Some types of filth, like pawn trash, are faster to clean than others, like '''bugblood'''.

Outdoors: Soil does not collect dirt from foot traffic  (it only adds dirt to the shoe soles of pawns), and therefore may be more beautiful to use outdoors than constructed streets.
However, in comparison to streets/paths in the base state soil tiles are only of neutral beauty and have a walk speed penalty.

Indoors: Soil does collect animal filth from Filth Rate. Indoor Soil also spreads dirt to pawns’ shoes. Indoor Soil has -1 cleanliness and -3 beauty per tile indoors.

== Summary table ==
{{Stub|section=1|reason=Sources of [[Ideology DLC]] filths. Add [[Biotech DLC]] filths}}
Certain unsightly objects, i.e. vomit, have one value when under a roof and a lower value when unroofed. This simulates the general disgust of seeing eyesores indoors versus encountering them outside. Some messes can be spread by pawns tracking through them and others can be washed away by rain.

The effect of filth on outdoors beauty is 30% of the effect indoors.
