Proc Details

proc
blow_up
(/mob/user)

used for sawing guns, causes the gun to fire without the input of the user

proc
on_unwield
(/obj/item/source, /mob/user)

triggered on unwield of two handed item

proc
on_wield
(/obj/item/source, /mob/user)

triggered on wield of two handed item

proc
process_fire
(/atom/target, /mob/living/user, message, params, zone_override, bonus_spread, burst_firing, spread_override, iteration)

Handles everything involving firing.

gun.dm is still a fucking mess, and I will document everything next time i get to it... for now this will suffice.

Returns TRUE or FALSE depending on if it actually fired a shot. Arguments:

target - The atom we are trying to hit.
user - The living mob firing the gun, if any.
message - Do we show the usual messages? eg. "x fires the y!"
params - Is the params string from byond /atom/proc/Click code, see that documentation.
zone_override - The bodypart we attempt to hit, sometimes hits another.
bonus_spread - Adds this value to spread, in this case used by dual wielding.
burst_firing - Not to be confused with currently_firing_burst. This var is TRUE when we are doing a burst except for the first shot in a burst, as to override the spam burst checks.
spread_override - Bullet spread is forcibly set to this. This is usually because of bursts attempting to share the same burst trajectory.
iteration - Which shot in a burst are we in.

proc
sawoff
(forced)

Used on init or try_sawoff

proc
try_sawoff
(/mob/user, /obj/item/saw)

Handles all the logic of sawing off guns,

gun /obj/item/gun
