Makes ship combat significantly more destructive (and a bit deadlier),
especially with non-explosive projectiles.
**Additions:**
- A shell that penetrates a solid (dense) structure will cause spalling.
This spall does 2-30 damage, depending on range and has a high embed
chance. These embedded chunks are large enough to be ripped out by hand.
(But you probably shouldn't). The pilot's suit has 30 ballistic armor,
so a prepared bridge crew can survive a lot of spall.
- Adds a gun that shoots any ship weapon that admins can spawn. Useful
for testing, or for adminbus where they don't want to have to spawn a
whole overmap ship.
- Made several structures destructible, vending machines, computer
frames, grilles (these were just bugged) and watertanks (and their
children). These structures could just block infinite shots and were
common enough to serve as effective armor for the horizon. These now
spawn shrapnel (of their material if it's set), in addition to sheets of
steel when destroyed.
- Added support for negative maim chance. This allows chosen projectiles
to be prevented from decapitating. No more accidentally gibbing the
bridge crew's heads. (Unless they get hit with something really really
big).
**Balance:**
- All non-explosive anti ship rounds got significant buffs. Typically
2-3x Anti-Material numbers.
- Armour piercing anti-ship rounds got massively increased penetration
stats. Typically 4-8 from 1-2.
- Doors now get destroyed in less hits, if they are hit by anti-material
projectiles. Hits to destroy -= Antimaterial / 2
- Francisca frag shells now shoot less fragments but deal more damage.
394 projectiles for every shot was a bit laggy, now it's only 280.
**Shields:**
Shields now take more power. 13-14 megawatts for a 10 strength shield.
Just inside the ship's generation capacity with both the INDRA and
Supermatter running.
Instead of deleting any projectile they are hit by, shields now have
different failure modes.
- Firstly, a piercing projectile has it's penetration reduced by the
shield strength. Eg A shot that would go through 10 walls, only
penetrates 4 after going through a 6 strength shield.
- Secondly, a projectile has it's damage multiplied by 1 - shield
strength / 10, then has shield strength subtracted from it's damage. Eg.
A damage 100 projectile, hitting a 5 strength shield, has it's damaged
reduced to 50, (100 * 0.5), then to 45. (50-5)
- Thirdly, an explosive projectile (that does not penetrate per the
first step) does not explode, but instead deals it's full damage to the
shield.
Hits to the shield now also damage the field itself, not just the shield
tile. As such, a very big hit on the shield can bring the whole thing
down, requiring an engineer to reset it.
Shields can now be upgraded with research components. Additionally,
shield generators can now support more than one capacitor. The
roundstart capacitor on the Horizon is only good enough to support a 6
strength shield.
The upgrades increase efficiency, strength loss over time and charge
speed.
**Overmap Targetting**
Previously, shells would spawn within 20 tiles of their target and aim
directly forwards. This was bugged for shots with burst, which would
instead all aim inwards and mostly miss. This is the reason the Grauwolf
(in addition to the explosion bug below) and Fransisca felt so useless,
only one of every shell in a burst would hit.
Shots now spawn at the map edge, based on the orientation of the
projectile and ship. Diagonals are now accounted for.
Shots are then aimed directly at the target selected on the console,
with 3 degrees of dispersion.
**Bugfixes:**
- Fixes lots of explosions that didn't pass a turf to the explosions
subsystem. This caused the explosion not to happen if the thing hit got
qdeled before the subsystem could get the turf to spawn the explosion
on.
- Embedded shrapnel no longer gets the initial projectile name, this
prevents it getting named shrapnelshrapnel.
- Fixes a bunch of projectile piercing bugs, mostly with grilles and
windows. Shots now go past window frames without hitting them.
- Fixes shields not having a click delay when attacked.

Repaths obj/machinery to obj/structure/machinery. **Note for
reviewers:** the only meaningful changed code exists within
**code/game/objects/structures.dm** and
**code/game/objects/structures/_machinery.dm**, largely concerning
damage procs. With the exception of moving airlock defines to their own
file, ALL OTHER CHANGES ARE STRICTLY PATH CHANGES.
Objects, _categorically_, are largely divided between those you can hold
in your hand/inventory and those you can't. Machinery objects are
already subtypes of Structures behaviorally, this PR just makes their
pathing reflect that, and allows for future work (tool actions, more
health/destruction functionality) to be developed without unnecessary
code duplication.
I have tested this PR by loading up the Horizon and dismantling various
machines and structures with tools, shooting guns of various types
throughout the ship, and detonating a bunch of explosions throughout the
ship.
Based on observed behavior in first live rounds following
https://github.com/Aurorastation/Aurora.3/pull/21862!
changes:
- balance: "Reduces Horizon multi-z hull generator Watt -> Renwick
conversion rate from 0.0002 to 0.00006, given increased capacitor
throughput and reactor outputs."
- balance: "Reduces maximum shield capacitor storage from 200 mJ to 20
mJ."
- bugfix: "Corrects Shield Capacitor TGUI displaying capacitor storage
as Watts instead of Joules."

machines for easier visual identification of whether or not clicking on
that emitter will kill you or not, etc."

better match that of the Emergency Shield Projector (and so they can use
the same overlays mentioned above)."
- imageadd: "Tweaks the Emitter's directional sprites slightly so that
the base doesn't seem to change shape quite so drastically when

Projectors."
- balance: "Increases power draw of Shield Wall Generators."
- balance: "Greatly reduces time for debugger to fix APCs corrupted by
electrical storms."

increasing temperature."
- balance: "Slight adjustments to space heater efficiency formula with a
friendly handwave to entropy."
- balance: "Old power cells have a 5% chance to be defective and have
slightly lower maxcharge than standard cells."
- qol: "Adds extended examine hints to engineering objects."
- qol: "Extends list of object types which INDRA core field will
interact peacefully with."
- qol: "Improved space heater UX (chat msgs changed to balloon alerts,
audible feedback, etc.)"
- code_imp: "Updates many code comments to use DMdocs."
- code_imp: "Consolidates various shield generation machine sprites in
scattered across multiple files into a single shield generator machines
sprite file."

Replace /datum/gas_mixture/proc/return_pressure with XGM_PRESSURE(xgm)
macro. Having such a relatively simple statement contributing proc
overhead to procs called millions of times is ridiculous
Rename /datum/gas_mixture/proc/zburn to react, deleting the old react
which was just an alias for it. Free proc overhead
Turn check_combustibility into a macro CHECK_COMBUSTIBLE(is_cmb, xgm).
also rewrite it slightly so that it only needs to do one pass. Its a bit
nasty so I apologize for that, but speeeeed.
Delete most powernet and obj/machinery/power procs for handling power,
replacing them with macros. The fact that we were unironically calling a
draw_power() on APCs to call draw_power() on their terminals to call
draw_power() on their powernet every single process tick was insane.
Turn `between` into a macro alias for clamp() since the param order is
different
turn `Percent` into a macro AS_PCT
Rewrite significant chunks of update_canmove so its not quite as
horrifying of a proc and hopefully doesn't eat the entire mob subsystem
every movement now
For a robust crafting system, I need a new materials framework.

changes:
Removed shim for old spark system.
Converted all calls to old spark system with calls to new one.
Processor-based effects are no longer pooled, as it had minimal performance impact and was breaking things.
