This article is about the current version of DF.
Note that some content may still need to be updated.

The following tokens can be used to define and use interactions.

Interaction Usage

In order to actually use an interaction, add the creature token [CAN_DO_INTERACTION:NAME] followed by a series of [CDI:...] tokens. Interactions can also be granted through syndromes using the token [CE_CAN_DO_INTERACTION] (plus the same series of CDI tokens).

The following CDI tokens can be specified:

Token Arguments Description
INTERACTION id Specifies which interaction can be performed. Only to be used with syndromes, since CE_CAN_DO_INTERACTION does not allow specifying the interaction ID directly.
TARGET target ID, target types Specifies how the creature chooses what to target. Target ID refers to an I_TARGET defined in the interaction itself. Multiple target types can be specified. If no target is specified, creature will target any available target within range, even through walls. Valid target types:
  • LINE_OF_SIGHT - the source needs to be able to see the target
  • TOUCHABLE - the source needs to be able to touch the target
  • DISTURBER_ONLY - the target must be whoever disturbed the source
  • SELF_ALLOWED - the target can be the source
  • SELF_ONLY - the target must be the source
TARGET_RANGE target ID, range Specifies how far away the target can be, in tiles. For SOLID_GLOB, LIQUID_GLOB and FIREBALL breath attacks, also determines how far the projectiles will fly before falling to the ground.
LOCATION_HINT Location Hint (see above) ?
USAGE_HINT Usage hint token Indicates when and how CPU-controlled creatures will use the interaction. If no hint is specified, the interaction will be used whenever a valid target is available. Valid values:
  • MAJOR_CURSE - Used in disturbance curses and deity curses. Targets the tomb disturber/temple defiler.
  • GREETING - Creatures will target 'friendly' creatures, usually at random.
  • CLEAN_SELF - Creature targets itself when covered in liquids or dust.
  • CLEAN_FRIEND - Same, but targets other friendly units.
  • ATTACK - Targets enemy creatures in combat. If the interaction specifies SELF_ONLY, CPU-controlled creatures will never use it.
  • FLEEING - Used when fleeing an enemy. Creature will target itself.
  • NEGATIVE_SOCIAL_RESPONSE - Used when a creature is expressing contempt (for example, to a murderer). Used for spitting by civilised races.
  • TORMENT
  • DEFENDv0.47.01 - Used in combat. Creature will target itself.
ADV_NAME text Specifies the interaction's name when used in Adventurer mode.
MAX_TARGET_NUMBER ID, number Specifies the maximum number of things that can be selected for a particular I_TARGET.
WAIT_PERIOD number Controls how often the interaction can be used.
VERBAL Only creatures that can speak will be able to use the interaction. Might also be needed for VERBAL_SPEECH.
VERBAL_SPEECH filename Specifies what the creature says when they perform the interaction. Filename path is relative to /data/speech.
CAN_BE_MUTUAL Presumably, allows two creatures with the same interaction to use it on each other simultaneously, for example, cats cleaning each other.
FREE_ACTION Indicates that performing the interaction doesn't take any time.
VERB self:other:mutual When a creature uses the interaction, a message will display, describing the source as doing this.
VERB_REVERSE ? ?
TARGET_VERB self:other When a creature uses the interaction, a message will display, describing the target as doing this.
BP_REQUIRED Body part criteria Indicates that a particular body part must be present in order to perform the interaction. Criteria are BY_CATEGORY:category, BY_TYPE:type, or BY_TOKEN:token.
FLOW Breath attack token Causes the interaction to create an effect not made of any material. Only makes sense for FIREBALL, FIREJET, or DRAGONFIRE.
MATERIAL Material token:Breath attack token Causes the interaction to create an effect made of a specific material. Doesn't make sense for FIREBALL, FIREJET, or DRAGONFIRE.

Breath attacks

Breath attacks are controlled by the MATERIAL_EMISSION interaction, like so: 

 [CAN_DO_INTERACTION:MATERIAL_EMISSION]
 		[CDI:ADV_NAME:Breath custom material]
 		[CDI:USAGE_HINT:ATTACK]
 		[CDI:BP_REQUIRED:BY_CATEGORY:MOUTH]
 		[CDI:MATERIAL:LOCAL_CREATURE_MAT:CUSTOMMATERIAL:TRAILING_VAPOR_FLOW]
 		[CDI:TARGET:C:LINE_OF_SIGHT]
 		[CDI:TARGET_RANGE:C:15]
 		[CDI:MAX_TARGET_NUMBER:C:1]
 		[CDI:WAIT_PERIOD:50]

The most important part is this line: 

 [CDI:MATERIAL:LOCAL_CREATURE_MAT:CUSTOMMATERIAL:TRAILING_VAPOR_FLOW]

The CDI refers to CAN_DO_INTERACTION; the MATERIAL states that this line shows what the material is. LOCAL_CREATURE_MAT:CUSTOMMATERIAL is your material, and TRAILING_VAPOR_FLOW refers to the breath attack type. Other types are seen below. Also important is this line: 

 [CDI:TARGET:C:LINE_OF_SIGHT]

LINE_OF_SIGHT refers to where the target C may be; others include SELF_ALLOWED (presumably like LINE_OF_SIGHT, but with the creature allowed to target itself), SELF_ONLY (preferable for undirected attacks and TOUCHABLE (for up-close attacks, as trailing flows tend to be).

Breath Attack Types

When using types of MATERIAL the format would be: [CDI:MATERIAL:material:sub-material:action-type] action-type being like SOLID_GLOB or UNDIRECTED_VAPOR

When using types of FLOW the format would just be: [CDI:FLOW:FIREBALL]

Token Usage Type Description
TRAILING_DUST_FLOW MATERIAL Lets out a cloud of solid dust. Appears to use cave-in dust physics, causing this to fling around anything it comes in contact with, making it capable of smashing creatures into the ground and flinging them over walls. Creature will attack as normal.
TRAILING_VAPOR_FLOW MATERIAL Shoots a trail of liquid mist at the target which can condense and trigger contact syndromes. Creature will attack as normal.
TRAILING_GAS_FLOW MATERIAL Shoots a trail of gas substance at the target which can be inhaled. Creature will attack as normal.
TRAILING_ITEM_FLOW:item token MATERIAL Shoots a "cloud" of items at the target, leaving piles of this item on the floor. Note that this does not create the actual items or use falling item mechanics (meaning no flying daggers or Touhou-style barrages, unfortunately). Instead, this token acts as TRAILING_GAS_FLOW, except that the material will use its normal temperature - for example, a breath attack of steel anvils will envelop the target in a "burst of steel". Creature will attack as normal.
SHARP_ROCKv0.47.01 MATERIAL Shoots a sharpened solid chunk of spinning substance at the creature, leaving symbols similar to broken arrows, essentially, a projectile weapon. If the cooldown rate is short enough, some creatures with this breath attack will not move, preferring instead to hold position and shoot shards at you, even when you are literally right next to them.
SOLID_GLOB MATERIAL Shoots a solid glob of spinning substance at the creature, leaving symbols similar to broken arrows, essentially, a projectile weapon. If the cooldown rate is short enough, some creatures with this breath attack will not move, preferring instead to hold position and shoot globs at you, even when you are literally right next to them.
LIQUID_GLOB MATERIAL Shoots a liquid glob of substance at the target. Contact syndromes will take effect if the glob hits the target's exposed skin.
SPATTER_POWDER MATERIAL Creates a pile of powder at the specified location.
SPATTER_LIQUID MATERIAL Creates a pool of liquid at the specified location.
UNDIRECTED_GAS MATERIAL Creature occasionally releases a cloud of gas substance. Similar to TRAILING_GAS_FLOW, but undirected, thus affecting a larger area but losing the distance. Creature will attack as normal.
UNDIRECTED_VAPOR MATERIAL Creature occasionally releases a cloud of liquid mist. Similar to TRAILING_VAPOR_FLOW, but undirected, thus affecting a larger area but losing the distance. Creature will attack as normal.
UNDIRECTED_DUST MATERIAL Creature occasionally releases a cloud of solid dust, which will spread and dissipate. Similar to TRAILING_DUST_FLOW, but undirected, thus affecting a larger area but losing the distance - range is roughly the same as that of a cave-in. Creature will attack as normal. DO NOT USE THIS TAG UNLESS YOU WANT TO KILL THE CREATURE AND EVERYTHING NEAR IT AND SEND PEOPLE FLYING. You know you want to.
UNDIRECTED_ITEM_CLOUD:item token MATERIAL Creature occasionally releases a "cloud" of items at the target, leaving piles of this item on the floor. The same comments apply as TRAILING_ITEM_FLOW. Creature will attack as normal.
WEB_SPRAY MATERIAL Emits a burst of webs that entangle target creatures.
DRAGONFIRE FLOW Emits a wide cone of dragon fire that burns target creatures at a scorching 50000 °U . For this you want FLOW instead of a material.
FIREJET FLOW Emits a narrow cone of fire that burns target creatures at 11000 °U . For this you want FLOW instead of a material.
FIREBALL FLOW Emits a fireball that burns the target creature. For this you want FLOW instead of a material.
WEATHER_CREEPING_GAS MATERIAL Creates a cloud of gas that appears at the edge of the map and slowly creeps across the map. Not usable by creatures.
WEATHER_CREEPING_VAPOR MATERIAL Creates a cloud of creeping vapor. Not usable by creatures.
WEATHER_CREEPING_DUST MATERIAL Creates a cloud of creeping dust. Not usable by creatures.
WEATHER_FALLING_MATERIAL MATERIAL Causes it to start raining a particular material. If the material is solid at the outdoor temperatures, it will snow the material instead. Regardless of the nature of the material, being caught in it will give dwarves the bad thought of being 'caught in freakish weather lately'. Not usable by creatures.

Keep in mind that you can use multiple breath attacks, which appears to make the creature choose between them at random. Creatures cannot use the WEATHER effects, these being reserved for regional interactions.

One major difference between GAS, VAPOR, and DUST is that if the material cannot exist in the specified state at the current temperature, it will automatically be created at a temperature allowing it to exist. So if you create a vapor spray that uses rock or metal as a material, that spray will be created at the material's melting point, setting everything it touches on fire. You can also create a freezing spray by using a custom material that has extremely low melting and/or boiling points.

If you give a creature a material breath attack, be aware that it will be caught in the attack more frequently than its targets. Make sure to make your creatures immune to their own breath weapons!
