v0.31:Contaminant
| This article is about an older version of DF. |
Contaminants are a new feature introduced with 0.31.01. There are numerous types of contaminants in Dwarf Fortress, such as mud, blood, (stone) dust, vomit, snow, and pus.
Creating Mud
Any time a tile is covered in Template:L, Template:L will be created on that tile. Mud is usually necessary before doing any kind of Template:L.
Tracking
With the creating of this new contaminants system Template:L and other Template:L that walk over contaminants can track them onto other tiles that they pass through. Dustings and spatterings which represent small amounts of a contaminant do not appear to be tracked around. Larger amounts of contaminants will be picked up by a dwarves left foot and can then be transferred to other tiles.
The tracking of contaminants is now a configurable option, which defaults to NO (in Dwarf Fortress mode). The actual options are WALKING_SPREADS_SPATTER_DWF and WALKING_SPREADS_SPATTER_ADV in data/init/d_init.txt.
Flowing
Water that Template:L over contaminants can pick them up and redistribute them as the water moves. Water does not appear to move mud, although mud will be created any time water covers a tile. The mechanics of redistributing contaminants using water is not well understood although there have been some observations of strange behavior when mixing blood and water.
- adding 7/7 water on top of a pool of blood creates more pools of blood at the edge of the water as it moves and evaporates.
- an overflowing reservoir that contains some blood creates blood everywhere the water flows.
- water will create mud on any non-muddy tile, and moving water will frequently redistribute the mud.
