Proc Details

proc
apply_gauze
(/obj/item/stack/gauze)

apply_gauze() is used to- well, apply gauze to a bodypart

As of the Wounds 2 PR, all bleeding is now bodypart based rather than the old bleedstacks system, and 90% of standard bleeding comes from flesh wounds (the exception is embedded weapons). The same way bleeding is totaled up by bodyparts, gauze now applies to all wounds on the same part. Thus, having a slash wound, a pierce wound, and a broken bone wound would have the gauze applying blood staunching to the first two wounds, while also acting as a sling for the third one. Once enough blood has been absorbed or all wounds with the ACCEPTS_GAUZE flag have been cleared, the gauze falls off.

Arguments:

gauze- Just the gauze stack we're taking a sheet from to apply here

proc
change_bodypart
(/obj/item/bodypart/new_type)

Proc to turn bodypart into another.

proc
check_wounding
(woundtype, damage, wound_bonus, bare_wound_bonus)

check_wounding() is where we handle rolling for, selecting, and applying a wound if we meet the criteria

We generate a "score" for how woundable the attack was based on the damage and other factors discussed in /obj/item/bodypart/proc/check_woundings_mods, then go down the list from most severe to least severe wounds in that category. We can promote a wound from a lesser to a higher severity this way, but we give up if we have a wound of the given type and fail to roll a higher severity, so no sidegrades/downgrades

Arguments:

woundtype- Either WOUND_BLUNT, WOUND_SLASH, WOUND_PIERCE, or WOUND_BURN based on the attack type.
damage- How much damage is tied to this attack, since wounding potential scales with damage in an attack (see: WOUND_DAMAGE_EXPONENT)
wound_bonus- The wound_bonus of an attack
bare_wound_bonus- The bare_wound_bonus of an attack

proc
check_woundings_mods
(wounding_type, damage, wound_bonus, bare_wound_bonus)

check_wounding_mods() is where we handle the various modifiers of a wound roll

A short list of things we consider: any armor a human target may be wearing, and if they have no wound armor on the limb, if we have a bare_wound_bonus to apply, plus the plain wound_bonus We also flick through all of the wounds we currently have on this limb and add their threshold penalties, so that having lots of bad wounds makes you more liable to get hurt worse Lastly, we add the inherent wound_resistance variable the bodypart has (heads and chests are slightly harder to wound), and a small bonus if the limb is already disabled

Arguments:

It's the same ones on [/obj/item/bodypart/proc/receive_damage]

proc
drop_limb
(special, dismembered)

limb removal. The "special" argument is used for swapping a limb with a new one without the effects of losing a limb kicking in.

proc
get_mangled_state
()

get_mangled_state() is relevant for flesh and bone bodyparts, and returns whether this bodypart has mangled skin, mangled bone, or both (or neither i guess)

Dismemberment for flesh and bone requires the victim to have the skin on their bodypart destroyed (either a critical cut or piercing wound), and at least a hairline fracture (severe bone), at which point we can start rolling for dismembering. The attack must also deal at least 10 damage, and must be a brute attack of some kind (sorry for now, cakehat, maybe later)

Returns: BODYPART_MANGLED_NONE if we're fine, BODYPART_MANGLED_FLESH if our skin is broken, BODYPART_MANGLED_BONE if our bone is broken, or BODYPART_MANGLED_BOTH if both are broken and we're up for dismembering

proc
get_organs
()

since organs aren't actually stored in the bodypart themselves while attached to a person, we have to query the owner for what we should have

proc
get_wound_type
(checking_type)

Get whatever wound of the given type is currently attached to this limb, if any

proc
on_owner_nolimbdisable_trait_gain
(/mob/living/carbon/source)

Called when TRAIT_NOLIMBDISABLE is added to the owner.

proc
on_owner_nolimbdisable_trait_loss
(/mob/living/carbon/source)

Called when TRAIT_NOLIMBDISABLE is removed from the owner.

proc
on_paralysis_trait_gain
(/obj/item/bodypart/source)

Called when TRAIT_PARALYSIS is added to the limb.

proc
on_paralysis_trait_loss
(/obj/item/bodypart/source)

Called when TRAIT_PARALYSIS is removed from the limb.

proc
painless_wound_roll
(wounding_type, phantom_wounding_dmg, wound_bonus, bare_wound_bonus, sharpness)

Allows us to roll for and apply a wound without actually dealing damage. Used for aggregate wounding power with pellet clouds

proc
seep_gauze
(seep_amt)

seep_gauze() is for when a gauze wrapping absorbs blood or pus from wounds, lowering its absorption capacity.

The passed amount of seepage is deducted from the bandage's absorption capacity, and if we reach a negative absorption capacity, the bandages falls off and we're left with nothing.

Arguments:

seep_amt - How much absorption capacity we're removing from our current bandages (think, how much blood or pus are we soaking up this tick?)

proc
set_brute_dam
(new_value)

Proc to hook behavior associated to the change of the brute_dam variable's value.

proc
set_burn_dam
(new_value)

Proc to hook behavior associated to the change of the burn_dam variable's value.

proc
set_can_be_disabled
(new_can_be_disabled)

Proc to change the value of the can_be_disabled variable and react to the event of its change.

proc
set_disabled
(new_disabled)

Proc to change the value of the disabled variable and react to the event of its change.

proc
set_owner
(new_owner)

Proc to change the value of the owner variable and react to the event of its change.

proc
set_stamina_dam
(new_value)

Proc to hook behavior associated to the change of the stamina_dam variable's value.

proc
try_dismember
(wounding_type, wounding_dmg, wound_bonus, bare_wound_bonus)

try_dismember() is used, once we've confirmed that a flesh and bone bodypart has both the skin and bone mangled, to actually roll for it

Mangling is described in the above proc, /obj/item/bodypart/proc/get_mangled_state. This simply makes the roll for whether we actually dismember or not using how damaged the limb already is, and how much damage this blow was for. If we have a critical bone wound instead of just a severe, we add +10% to the roll. Lastly, we choose which kind of dismember we want based on the wounding type we hit with. Note we don't care about all the normal mods or armor for this

Arguments:

wounding_type: Either WOUND_BLUNT, WOUND_SLASH, or WOUND_PIERCE, basically only matters for the dismember message
wounding_dmg: The damage of the strike that prompted this roll, higher damage = higher chance
wound_bonus: Not actually used right now, but maybe someday
bare_wound_bonus: ditto above

proc
update_wounds
(replaced)

update_wounds() is called whenever a wound is gained or lost on this bodypart, as well as if there's a change of some kind on a bone wound possibly changing disabled status

Covers tabulating the damage multipliers we have from wounds (burn specifically), as well as deleting our gauze wrapping if we don't have any wounds that can use bandaging

Arguments:

replaced- If true, this is being called from the remove_wound() of a wound that's being replaced, so the bandage that already existed is still relevant, but the new wound hasn't been added yet
