## About The Pull Request
~~Kept you waitin huh!~~
The projectile refactor is finally here, 4 years later. This PR (almost)
completely rewrites projectile logic to be more maintainable and
performant.
### Key changes:
* Instead of moving by a fixed amount of pixels, potentially skipping
tile corners and being performance-heavy, projectiles now use
raymarching in order to teleport through tiles and only visually animate
themselves. This allows us to do custom per-projectile animations and
makes the code much more reliable, sane and maintainable. You (did not)
serve us well, pixel_move.
* Speed variable now measures how many tiles (if SSprojectiles has
default values) a projectile passes in a tick instead of being a magical
Kevinz Unit™️ coefficient. pixel_speed_multiplier has been retired
because it never had a right to exist in the first place. __This means
that downstreams will need to set all of their custom projectiles' speed
values to ``pixel_speed_multiplier / speed``__ in order to prevent
projectiles from inverting their speed.
* Hitscans no longer operate with spartial vectors and instead only
store key points in which the projectile impacted something or changed
its angle. This should similarly make the code much easier to work with,
as well as fixing some visual jank due to incorrect calculations.
* Projectiles only delete themselves the ***next*** tick after impacting
something or reaching their maximum range. Doing so allows them to
finish their impact animation and hide themselves between ticks via
animation chains. This means that projectiles no longer disappear ~a
tile before hitting their target, and that we can finally make impact
markers be consistent with where the projectile actually landed instead
of being entirely random.

### But how will this affect the ~~trout population~~ gameplay?
Beyond improved visuals, smoother movement and a few minor bugfixes,
this should not have a major gameplay impact. If something changed its
behavior in an unexpected way or started looking odd, please make an
issue report.
Projectile impacts should now be consistent with their visual position,
so hitting and dodging shots should be slightly easier and more
intuitive.
This PR should be testmerged extensively due to the amount of changes it
brings and considerable difficulty in reviewing them. Please contact me
to ensure its good to merge.

## Why It's Good For The Game
Our core projectile code is an ungodly abomination that nobody except
me, Kapu and Potato dared to poke in the past months (potentially
longer). It is laggy, overcomplicated and absolutely unmaintaineable -
while a lot of decisions made sense 4 years ago when we were attempting
to introduce pixel movement, nowadays they are only acting as major
roadblocks for any contributor who is attempting to make projectile
behavior that differs from normal in any way.
Huge thanks to Kapu and Potato (Lemon) on the discord for providing
insights, ideas and advice throughout the past months regarding
potential improvements to projectile code, almost all of which made it
in.
## Changelog
🆑
qol: Projectiles now visually impact their targets instead of
disappearing about a tile short of it.
fix: Fixed multiple minor issues with projectile behavior
refactor: Completely rewrote almost all of our projectile code - if
anything broke or started looking/behaving oddly, make an issue report!

## About The Pull Request
All usages of world.icon_size in code have been replaced with new
`ICONSIZE_X`, `ICONSIZE_Y` and `ICONSIZE_ALL` defines depending on
context
Replaces some "32" magic numbers with the defines
A few bits of code have been modified to split up x/y math as well
## Why It's Good For The Game
Magic number bad, code more readable, code more flexible and I'm told
there's an access cost to doing world.icon_size so minor performance
gains
## Changelog
🆑 tonty
code: made some code relating to the world's icon size more readable

## About The Pull Request
Hey there,
This took a while to do, but here's the gist:
Python file now regexes every file in `/code` except for those that have
some valid reason to be tacking on more global defines. Some of those
reasons are simply just that I don't have the time right now (doing what
you see in this PR took a few hours) to refactor and parse what should
belong and what should be thrown out. For the time being though, this PR
will at least _halt_ people making the mistake of not `#undef`ing any
files they `#define` "locally", or within the scope of a file.
Most people forget to do this and this leads to a lot of mess later on
due to how many variables can be unmanaged on the global level. I've
made this mistake, you've made this mistake, it's a common thing. Let's
automatically check for it so it can be fixed no-stress.
Scenarios this PR corrects:
* Forgetting to undef a define but undeffing others.
* Not undeffing any defines in your file.
* Earmarking a define as a "file local" define, but not defining it.
* Having a define be a "file local" define, but having it be used
elsewhere.
* Having a "local" define not even be in the file that it only shows up
in.
* Having a completely unused define*
(* I kept some of these because they seemed important... Others were
junked.)
## Why It's Good For The Game
If you wanna use it across multiple files, no reason to not make it a
global define (maybe there's a few reasons but let's assume that this is
the 95% case).
Let me know if you don't like how I re-arranged some of the defines and
how you'd rather see it be implemented, and I'd be happy to do that.
This was mostly just "eh does it need it or not" sorta stuff.
I used a pretty cool way to detect if we should use the standardized
GitHub "error" output, you can see the results of that here

## Changelog
Nothing that really concerns players.
(I fixed up all this stuff using vscode, no regexes beyond what you see
in the python script. sorry downstreams)
* Moves spawners and decals to a different init/delete scheme
Rather then fully creating and then immediately deleting these things,
we instead do the bare minimum.
This is faster, if in theory more fragile. We should be safe since any
errors should be caught in compile since this is very close to a
"static" action. It does mean these atoms cannot use signals, etc.
* Potentially saves init time, mostly cleans up a silly pattern
We use sleeps and INVOKE_ASYNC to ensure that handing back turfs doesn't
block a space reservation, but this by nature consumes up to the
threshold and a bit more of whatever working block we were in.
This is silly. Should just be a subsystem, so I made it one, with
support for awaiting its finish if you want to
* Optimizes garbage/proc/Queue slightly
Queue takes about 1.6 seconds to process 26k items right now.
The MASSIVE majority of this time is spent on using \ref
This is because \ref returns a string, and that string requires being
inserted into the global cache of strings we store
What I'm doing is caching the result of ANY \ref on the datum it's
applied to. This ensures previous uses will never decay from the string
tree.
This saves about 0.2 seconds of init
Done using this command sed -Ei 's/(\s*\S+)\s*\t+/\1 /g' code/**/*.dm
We have countless examples in the codebase with this style gone wrong, and defines and such being on hideously different levels of indentation. Fixing this to keep the alignment involves tainting the blames of code your PR doesn't need to be touching at all. And ultimately, it's hideous.
There are some files that this sed makes uglier. I can fix these when they are pointed out, but I believe this is ultimately for the greater good of readability. I'm more concerned with if any strings relied on this.
Hi codeowners!

Timers, signals, and components need to know when the thing they're
attached to is getting destroyed or bad things happen. Since any datum
can make use of these every destroy needs to call parent.
Adds spell cards. They're a wizard spell that shoots a burst of 5 semi-accurate homing cards.
Projectiles now have a homing framework, complete with some variant of simulated inaccuracy.
The said wizard spell will make use of a new mob component, that allows that mob to select targets by moving their cursor near them. It will give a visual and lock onto the nearest mob to the cursor, allowing the homing projectiles to target on the locked on mob/object.
Removes colliding variable from projectiles - We never used it after Bump was refactored to Collide.
Images soon when I get the lockon datum-components to work.
* Cross Z support
* Fixes projectile cross-Z
* removes unnecessary code
* don't draw impacts if you're not impacting
* fix
* unneeded var
* No mapcheck()ing anymore, space does it for us 2.0
Moves beam rifle snowflake code up to projectile level for a proper hitscan system.
