## About The Pull Request
Right now, each time life processes we need to run has_gravity, and
check its output against a bunch of thresholds.
We could save off that second bit by caching the previous value, but
we'd still be only updating this every 2 seconds.
This potentially delayed updating leads to really janky feeling behavior
around transition points too (like when moving on/off the sand on tram
station)
So instead of doing this updating off life(), let's make it event based.
We'll decompose has_gravity, and take all the values it relies on, and
check for them changing ourselves.
That way we get instant response, and can save all the wasted
has_gravity calls.
This constant checking on movement adds a few signal registrations, a
connect_loc, and some logic on living/Moved
The Moved logic increases Moved's self by 50%, roughly 1 second a round
at worst.
Don't have concrete numbers for the connect_loc
(new self / old self)
In constrast, handle_gravity is currently on average maybe 15 seconds.
I could JUST save maybe 13 seconds and not spend the 1 by storing the
previous gravity value, but I think this is worth the ux changes. It
does add some extra resistance to change, but s much nice.
Moved some functions around too, and removed now redundant
update_gravity calls
## Why It's Good For The Game
Snappier gravity, faster Life()
## Changelog
🆑
qol: Human gravity will react to changes instantly, instead of waiting
for the next process tick. Hopefully this feels better and not worse
