- New near_unloaded API that supports custom
distance parameter, map bounds check, and
some optimizations.
- Add area automatic unload check support to ABM
API and add to applicable ABMs, replacing many
old manual checks.
Note that the explicit unload check is only strictly
necessary when something will happen due to
a node NOT being present in the area, e.g. something
igniting due to absent coolant, or soaking quantity
being reset due to missing sources. In simple cases
where the absence of a thing causes the ABM to do
nothing, then the standard check can work because
the default action is to do nothing anyway.
Witness checks include data about the node in
place at the time that the witness even occurred,
so players are not awarded credit if the node they
see there was changed again afterwards. A lot of
old witness code inserted the witness right
before the node was changed, since the node
change was done as a tail call, but this does not
work with delayed witnessing because the
delayed witness data would be tied to the old
node, not the replacement one.
Moving witness to after node setting should fix
a number of broken hints that should have been
delayed-witnessable, e.g. brick bonding.
This makes mass-production of etched concrete
nodes a lot less tedious and more interesting.
There's now an incentive to manage multiple
separate styluses for larger projects.
By restricting the recipes we check based
on the name of the central object being
checked, we can do many fewer craft
checks per item and avoid expensive
checks.
Register a "rootmatch" property for all
recipes that represents a broader, quicker
test for recipe eligibility. False positives are
allowed but false negatives are not.
Since most recipes are eligible, we can
use this to build an index for fast lookups
of subsets of recipes to run and skip most
of the other ones.
