- 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.
We were using action log level for a lot of
things because by default MT does not seem
to capture info logs to stderr. On "production"
servers though this makes too much noise and
makes it hard to find actual player actions.
Servers that want info logging will just have
to configure/compile it in.
It seems like Minetest actually generates terrain
beyond the map limit boundaries and raycast
and get_node can retrieve them server-side, even
though they aren't rendered client-side and air is
still filled with ignores. This causes players to see
"stone" with looktips looking thru the bottom of
the world. Fix it with an explicit check for world
bounds.
