projectile

This file is not good Fucked up var names lie ahead Caution, traveler

General cleanup todo: Go through undocumented math and document it Remove bad vars, fill in gaps then created Deduplicate info between this and proj_data

Vars
angle	Angle of this shot. For reference @see setup()
armor_ignored	Does this projectile pierce armor?
called_target	Target for called shots behavior - by default does not affect projectile behaviour
called_target_turf	Turf of the called_target during projectile initialization
collide_with_other_projectiles	Below stuff but also this is dumb and only used for frost bats and I don't even know why it's used there. TODO remove
crossing	No clue. Assoc list seems like? Also accessed as a non-assoc list sometimes. fuck. TODO
curr_t	No clue. Related to curr_t. TODO
data	Arbitrary projectile data. Currently only used to hold an object that a projectile is seeking for a singular type. TODO remove
facing_dir	Default dir, set to in do_step()
forensic_ID	Forensic ID of the gun, etc that shot this projectile, used for forensics on implanted projectiles
goes_through_mobs	Whether this projectile can freely pass through mobs
goes_through_walls	Whether this projectile can freely pass through dense turfs
has_died	For disabling collision when a projectile has died but hasn't been disposed yet, e.g. under on_end effects
hitlist	List of atoms collided with this tick
implanted	What kind of implant this projectile leaves in impacted mobs
incidence	Reflection normal on the current tile (NORTH if projectile came from the north, etc.) TODO can maybe be replaced with a single dir check when relevant? not 100% sure why we need to track this always. Might be crucial, dunno
initial_power	TODO this var also feels dumb. convert to initial() prolly (on data not on this)
is_processing	Yeah this sucks. TODO remove. I don't care bring the bug back so we can actually fix it
max_range	Maximum range this projectile can travel before impacting a (non-dense) turf
mob_shooter	Mob-typed copy of `shooter` var to save time on casts later
orig_turf	Original turf this projectiles was fired from
pierces_left	Number of impassable atoms this projectile can pierce. Decremented on pierce. Can probably be axed in favor of the component. TODO remove
power	One of the two below vars needs to be renamed or removed. Fucking confusing I don't know why this var is here it just stores the result of a proc called on the proj data. TODO revisit
proj_data	Projectile data; almost all specific projectile information and functionality lives here
reflectcount	Number of times this projectile has been reflected off of things. Used to cap reflections
shooter	The mob/thing that fired this projectile
special_data	Bullshit var for storing special data for niche cases. Sucks, is probably necessary nonetheless
targets	List of all targets this projectile can go after; useful for homing projectiles and the like
ticks_until_can_hit_mob	Tracks the number of steps before a piercing projectile is allowed to hit a mob after hitting another one. Scarcely used. TODO remove?
travelled	Number of tiles this projectile has travelled
was_pointblank	Whether this projectile was shot point-blank style (clicking an adjacent mob). Adjusts the log entry accordingly
was_setup	TODO axe this after testing. Used very infrequently, looks redundant
wx	What the fuck is this comment your shit jesus christ ????? TODO
xo	TODO dunno what these are. guessing 'original x' and 'original y' but all the code involving them is mathy and i don't have the patience rn Fill in if u know ty
