proc
expose_turf
(/turf/exposed_turf, reac_volume)

Applies this reagent to a /turf

proc
get_inverse_purity
(purity)

Gets the inverse purity of this reagent. Mostly used when converting from a normal reagent to its inverse one.

Arguments

purity - Overrides the purity used for determining the inverse purity.

proc
get_taste_description
(/mob/living/taster)

Should return a associative list where keys are taste descriptions and values are strength ratios

proc

proc
normalise_creation_purity
(normalise_num_to, creation_purity)

Used when you want the default reagents purity to be equal to the normal effects (i.e. if default purity is 0.75, and your reacted purity is 1, then it will return 1.33)

Arguments

normalise_num_to - what number/purity value you're normalising to. If blank it will default to the compile value of purity for this chem
creation_purity - creation_purity override, if desired. This is the purity of the reagent that you're normalising from.

proc
on_burn_wound_processing
(/datum/wound/burn/flesh/burn_wound)

Called in burns.dm if the reagent has the REAGENT_AFFECTS_WOUNDS process flag

proc
on_hydroponics_apply
(/obj/machinery/hydroponics/mytray, /mob/user)

Called when this chemical is processed in a hydroponics tray.

Can affect plant's health, stats, or cause the plant to react in certain ways.

proc
on_merge

Called when two reagents of the same are mixing.

proc
on_mob_add
(/mob/living/affected_mob, amount)

proc
on_mob_dead
(/mob/living/carbon/affected_mob, seconds_per_tick)

Ticks on mob Life() for as long as the reagent remains in the mob's reagents.

Usage: Parent should be called first using . = ..()

Exceptions: If the holder var needs to be accessed, call the parent afterward that as it can become null if the reagent is fully removed.

Returns: UPDATE_MOB_HEALTH only if you need to update the health of a mob (this is only needed when damage is dealt to the mob)

Arguments

mob/living/carbon/affected_mob - the mob which the reagent currently is inside of
seconds_per_tick - the time in server seconds between proc calls (when performing normally it will be 2)

Called after a reagent is transferred

proc
overdose_process

Called if the reagent has passed the overdose threshold and is set to be triggering overdose effects. Returning UPDATE_MOB_HEALTH will cause updatehealth() to be called on the holder mob by /datum/reagents/proc/metabolize.

proc
overdose_start
