Minetest game's doors mod was known to cause server errors when passed a nil digger in it's can_dig callback,
due to always attempting to invoke digger:get_player_name().
Fix this by providing a basic fake player which provides this method to can_dig callbacks.
(It should be noted that currently this fix causes doors to be undiggable by quarries.)
model includes a flat extension on one "side" to fix #342
rotate the reactor with the screwdriver with shift-right-click before filling, to
line up the flat side with your cabling. Note that the reactor doesn't actually
care which side the cable comes from.
delete back/bottom texture for power monitor
use "machine bottom" for bottom of force field generator
add cable connection overlay, use it on various machines' bottoms/sides, as appropriate
Radiation now slowly damages you for a while after exposure,
with the effect's time and intensity proportional to the
amount of radiation received. The radioactivity of some
items is reduced to account for the increased damage.
This simplifies radioactivity by removing the 1000 and 0.25 multipliers.
It also increases the effectiveness of protection (I think it was too low
before -- most of the advantage of adding protective layers was just from
the increased distance).
The reactor originaly used a stainless steel shield only
because lead wasn't yet available. Stainless steel shields
are automatically converted to lead shields for legacy reasons.
Changes:
* Make rayIter a global utility, and use it for radiation too.
* prettynum -> pretty_num and cleanup.
* Remove resolve_name/function_exists (unused).
* Cleanup nuclear reactor code.
Adds a cache to the quarry in order to reduce load and send larger stacks through pipes instead of just single items. Coin tossing ensures the cache gets purged around every 200 seconds. The interval isn't fixed in order to prevent material spikes from multiple quarries which got loaded simultaneously. When the cache is full, or the quarry finished, it is purged too.
Don't load the whole digging area when only a small piece is relevant.
Also, move the (time expensive) check whether the air above a block is free to the last position, which spares unneccessary checks when multiple quarries are placed together, or a quarry has to loop over air for another reason.
Squeeze the range of material shielding values. The strongest shielding
materials get weaker, and weaker shielding materials, especially low-end
ones such as dirt, get stronger. The radioactivity of the active
reactor core is increased so that the standard shielding is (still)
only narrowly sufficient.
Make the "radioactive" group value be the safe distance in millimeters
rather than meters, to allow for intermediate values. Use such
intermediate values for the uranium blocks, using the existing formula
with this finer quantisation. All other radioactive nodes retain their
existing radioactivity exactly.
The quarry used to get stuck when it encountered an undiggable node.
Change it to skip past that node, digging whatever later stuff it can.
Necessarily, the current digging position becomes semantically-significant
state: it is no longer sufficient to search the quarry cuboid from the top
on each iteration. The current digging height is reported in the quarry's
interaction form, and can be reset to the top using a button on the form.
Where there is a non-air node within the quarry directly above the
next node to dig, it blocks the quarry's access to that node, even if
everything involved is diggable. Thus an undiggable node casts a shadow
of undug nodes below it. Resolving undiggability of a node is a major
reason to use the restart button.
The new API function is now renamed to pipeworks.tube_inject_item(),
so use it under that name. If it is not available, synthesise the new
API in terms of the old one.
With breaking an active reactor core now causing instant meltdown, having
it breakable by hand is too hazardous. Change it to match steel block,
which constitutes the main part of the rest of the reactor structure.
Replacing the extractor-based system, uranium to be used as reactor fuel
must now be enriched in stages using the centrifuge. Uranium metal can
exist at 36 levels of fissile content, from 0.0% to 3.5% in steps of 0.1%.
One round of centrifuging splits two dust of a particular grade in to one
dust each of the two neighbouring grades. Uranium of each grade can exist
as dust, ingot, and block, with all the regular metal processes to convert
between them. Uranium from ore exists in lump form, and is 0.7% fissle.
The blocks are radioactive to a degree dependent on fissile content.
Thus the chemical refinement and processing of uranium now follows the
standard pattern for metals, and is orthogonal to isotopic enrichment.
Each form of uranium (dust, ingot, block) intentionally looks identical
regardless of fissile grade.
If technic_worldgen is used alone, it defines only one grade of uranium
(as before), but defines it in the regular metal pattern, with lump, ingot
produced by cooking lump, and block crafted from ingots. It identifies
the metal only as "uranium". The multiple grades of uranium are defined
by the technic mod, which identifies each grade as "N.N%-fissile
uranium". The single grade that was registered by technic_worldgen
is redefined to be described specifically as "0.7%-fissile uranium".
For the redefinition to work, technic_worldgen must load before technic,
so technic now declares a dependency on technic_worldgen.
Each fuel rod is made from five 3.5%-fissile ingots, each of which in
turn requires one to start with five 0.7%-fissile dust, so each fuel rod
is now derived from 12.5 uranium lumps (or 25 if the lumps were first
cooked rather than being ground). This replaces the 20 lumps required
by the former recipes. After setting up and priming the centrifuge
cascade, enriching a full set of fuel for the reactor (six fuel rods)
takes 14700 centrifuge operations. It's intended to be a practical
necessity to automate the centrifuge. In the absence of EU upgrades
for the centrifuges, these operations consume 5.88e8 EU, about 0.97%
of the 6.048e10 EU that the fuel set will produce in the reactor.
The intent is that, in this respect as in others, operating a reactor
should carry a very high up-front cost, but ultimately be very profitable.
As the layers of reactor structure now have a practical purpose,
in attenuating the modelled radiation from the core, it is no longer
necessary to make so much of it mandatory in order to motivate players
to build it.
The siren sounds a "danger" tone continuously while it is active and
damaged, such that meltdown is imminent. It sounds a one-off "clear"
tone if it has been sounding "danger" and the danger has passed, either
because the structure is repaired or because the reactor has become idle.
The meltdown check now doesn't trigger meltdown immediately on reactor
structure being compromised. Instead, there's a grace period of up to
100 s, during which the reactor can be repaired. The check doesn't just
look at whether the structure is damaged at all: it looks at how damaged
it is, counting the number of faulty nodes. The amount of damage is
integrated over time, and the grace period is actually 100 node-seconds,
so greater damage causes meltdown more quickly. If the active core is
dug then it melts down immediately, preventing the tactic of digging
the core to avert meltdown.
Incidentally move the meltdown check into its own ABM, from the
technic_run callback, so that it applies even when the reactor is not
connected to a switching station.
Radiation is attenuated exponentially by passing through shielding
material. Radiation resistance values are assigned to all bulk-material
nodes, and the radiation damage ABM traces the path of each radiation ray
to count up the shielding. The relative radiation resistance values are
essentially real, but the effectiveness of all shielding is scaled down
by a factor of about 70 for game purposes. Strength of the existing
radiation sources is increased by varying amounts to compensate for
shielding. Uranium block and ore, both usable as shielding, are made
slightly radioactive, the latter only very slightly.
