* pass_flags handling refactor + rewrites a part of projectiles for the n-th time (#54924)
Yeah uhh this'll probably need testmerging even after it's done because yeah it's a bit big.
If y'all want me to atomize this into two PRs (pass flags vs projectiles) tell me please. Pass flags would have to go in first though, in that case, as new projectile hit handling will rely on pass_flags_self.
Pass flags:
Pass flags handling now uses an atom variable named pass_flags_self.
If any of these match a pass_flag on a thing trying to pass through, it's allowed through by default.
This makes overriding CanAllowThrough unnecessary for the majority of things. I've however not removed overrides for very.. weird cases, like plastic flaps which uses a prob(60) for letting PASSGLASS things through for god knows why.
LETPASSTHROW is now on pass_flags_self
Projectiles:
Not finalized yet, need to do something to make the system I have in mind have less unneeded overhead + snowflake
Basically, for piercing/phasing/otherwise projectiles that go through things instead of hitting the first dense object, I have them use pass_flags flags for two new variables, projectile_phasing and projectile_piercing. Anything with pass_flags_self in the former gets phased through entirely. Anything in the latter gets hit, and the projectile then goes through. on_hit will also register a piercing hit vs a normal hit (so things like missiles can only explode on a normal hit or otherwise, instead of exploding multiple times. Not needed as missiles qdel(src) right now but it's nice to have for the future).
I still need to decide what to do for hit handling proper, as Bump() is still preferred due to it not being as high-overhead as something like scanning on Moved(). I'm thinking I'll make Moved() only scan for cases where it needs to hit a non-dense object - a prone human the user clicked on, anything special like that. Don't know the exact specifics yet, which is why this is still WIP.
Projectiles now use check_pierce() to determine if it goes through something and hits it, doesn't hit it, or doesn't go through something at all (should delete self after hitting). Will likely make an on_pierce proc to be called post-piercing something so you can have !fun! things like projectiles that go down in damage after piercing something. This will likely deprecate the process_hit proc, or at least make it less awful.
scan_for_hit() is now used to attempt to hit something and will return whether the projectile got deleted or not. It will delete the projectile if the projectile does hit something and fails to pierce through it.
scan_moved_turf() (WIP) will be used for handling moving onto a turf.
permutated has been renamed to impacted. Ricocheting projectiles get it reset, allowing projectiles to pierce and potentially hit something again if it goes back around.
A new unit test has been added checking for projectiles with movement type of PHASING. This is because PHASING completely causes projectiles to break down as projectiles mainly sense collisions through Bump. The small boost in performance from using PHASING instead of having all pass flags active/overriding check_pierce is in my opinion not worth the extra snowflake in scan_moved_turf() I'd have to do to deal with having to check for hits manually rather than Bump()ing things.
Movement types
UNSTOPPABLE renamed to PHASING to better describe what it is, going through and crossing everything but not actually bumping.
Why It's Good For The Game
Better pass flags handling allows for less proc overrides, bitflag checks are far less expensive in general.
Fixes penetrating projectiles like sniper penetrators
This system also allows for better handling of piercing projectiles (see above) without too much snowflake code, as you'd only need to modify on_pierce() if you needed to do special handling like dampening damage per target pierced, and otherwise you could just use the standardized system and just set pass flags to what's needed. If you really need a projectile that pierces almost everything, override check_pierce(), which is still going to be easier than what was done before (even with snowflake handling of UNSTOPPABLE flag process_hit() was extremely ugly, now we don't rely on movement types at all.)

Replaces like 70-80% of 0 and such, as a side effect cleaned up a bunch of returns
Edit: Most left out ones are in mecha which should be done in mecha refactor already
Oh my look how clean it is

Fixes throw_at() to look nicely for xeno leap by adding the diagonals_first argument.
Removes useless gateway/Crossed and gateway/Bumped().
Changes throw_at() to use diagonal directions.
I replaced the atom variable "throwpass" with the LETPASSTHROW pass_flags
I readded hit_check proc to catch things getting on the thrown thing's tile during its sleep(1) (especially needed for mobs running towards the thing), the only other possibility would've been to add throwing checks in atom/movable/Crossed() (called after every move) and I don't think it'd be worth it.
I added the item var "thrownby" to be able to continue to log the thrower of the item when it hits a mob. It removes the need for a thrower argument in throw_impact() and hitby().
They
This means that multi-tile things may not handle correctly, but the only thing that used it was atmos for double wide doors, and they are used in one location that is unlikely to have atmos changes
see: http://www.byond.com/forum/?post=1852790 for justifcation. (tl;dr: accessing .locs causes memory leaks)
Adjusts the click code to not use client/Click(). The code is largely unchanged, except that it allows the compiler default behaviour of calling atom/Click(), and then forwards the call to mob/ClickOn(). I had some reports that melee combat mixed with movement was behaving oddly, and I believe it may be due to the use of client/Click; the byond documentation says that redefining client/Click() causes additional overhead, and it isn't strictly necessary.
Alters the way double clicks are handled, in an attempt to better handle clickspam, as often occurs during pitched combat. This may also be responsible for the above, but I don't know.
Inserts proximity (aka flag) checks in all afterattack() procs. The old assumption was that unless an item used the USEDELAY flag, afterattack() was only called when adjacent, but this is no longer true. This led to beakers, soap, crayons, etc, all being usable at all ranges.
Removes the NODELAY flag, which was unused. Removes all existing uses of the USEDELAY flag so that it can be readded to things that need extra delay.
Removes the hand_* procs, previously used by restrained actions. Instead, the mob helper mob/RestrainedClickOn() has abosrbed basically all the functionality they were used for, which is really only monkeys with jungle fever.
Adds a special case of the Adjacency() proc for doors. This fixes#136, airlocks being unreachable due to border fire doors. However, this only takes us back to the unpleasant position where you have to open-hand the door, switch to a crowbar, and pry open the firedoor; it still needs a better fix.
Modifies Adjacent() for items, to allow items to be accessed properly inside each other and the user. This fixes a few bugs seen in testing.
Sets a maximum telekinesis range (in case you were using cameras).
The telekinetic grab now does nothing at all in melee combat. This prevents double messages where you attack them with the object telekinetically, and then also attack them with the telekinetic grab.
Crayons had a bug where they were drawing at all distances. This is because in old click code, afterattack() only happened at range when you had the USE_DELAY flag, which is no longer true. Proper behavior is to use parameter 3 (proximity_flag), which is 1 when adjacent or 0 if inaccessible.
This adds two atom procs, attack_tk() and attack_self_tk(). attack_tk is used as per attack_hand; attack_self_tk exists on all atoms (not just items) but is similar to the item proc, but without the assumption that it is in the user's hand.
Removes the functionality where entering throw mode would create a tk grab, as it is redundant.
As a default, attack_tk does the following:
* Creates a telekinetic throw for items and un-anchored objects
* Does an attack_hand (paw, animal, etc) for anchored objects
* Does nothing to mobs
As a default, attack_self_tk does nothing. An attack_self_tk was added to closets to open and close them since that's a common thing.
The following items have added attack_tk procs:
* Fire axe cabinet, extinguisher cabinet, and bedsheet bin will drop into their square instead of putting it in your hand
* Doors only open telekinetically if they require no access
* Chairs will rotate if nobody is buckled to them
* Filing cabinets will remove a paper at random.
* Tables and racks return to prevent telehulk smash
This is INCOMPLETE. Adding proper TK interaction to everything is something best done in pieces.
In particular, interacting with mobs and items both open up the floodgates for bugs, so we/I need to decide how we want it to go before we commit, and then fix bugs along the way. Stumbling forward, fixing bugs, and then changing course halfway would be a bad idea.
Fixes#646, #579, #863
Completely redoes the click code. Moves all click related code into code/_onclick for reference. Also moves hud datum code and all the screen object code I could find into code/_onclick/hud, as it is related. Item attack(), attackby(), afterattack(), and attack_self() have been moved into item_attack.dm for consistency.
Completely removes dummy objects and adds atom.Adjacent(user). This proc checks for border items and anything marked with throwpass for determining whether or not you can reach a given square. A turf helper, ClickCross(), was added to facilitate this.
Removes the monolithic Atom.Click() proc in favor of an overridable click handler attached to mobs. Click code no longer uses the : path operator as a consequence, and mob/lastDblClick has been moved to Client/next_click. A few end arounds were necessary (screen objects, buildmode, and spells), but this has been handled by repurposing Atom.Click(); if you have special click code, insert it in the object's Click() function and return 1 to prevent normal processing.
This update adds support for attack_ghost(); the previous "new" click handler had support for it but was never finished. I have taken the liberty of letting ghosts click portals, the gateway, and the teleporter to jump to the intended target square, and kept the previous default action of examine()ing every damn thing you click. It is to be suggested that you could do more with this proc when ghost interactions are enabled.
This update also adds support for double clicking. It is currently only used for ghosts and AIs, because the original (first) click still registers normally. For both of these, double clicking a square will jump you to it, and double clicking a mob will follow it. In the case of ghosts, double clicking bots and the singularity will also set you following it; if you double click your own corpse, you will re-enter it; this also works if your body is in a closet, sleeper, DNA scanner, etc. Default mobs ignore double clicks as normal.
-- NOTE --
There are two flags which were previously unused or misused by click code: USEDELAY and NODELAY. Ostensibly, USEDELAY would double the normal 1sec delay, and NODELAY would remove it.
Using either of these flags as intended would significantly affect the timing of the game. In particular, USEDELAY is currently applied to guns and about everything else that acts at range. I am adding USEDELAY as a half-second increase for now, but I have not put a significant amount of thought into it. I considered lowering the normal 1sec delay to .8sec to balance it, but the consequences of that on combat involve more calculations than I care to make.
NODELAY seems to never have been used, and I did not implement it, but I could do so trivially.
