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.
Tool workshop can now accept tools to repair via tube. It has upgrade
slots. Battery upgrade reduces its power consumption. Tube upgrade
makes it eject fully-repaired (or unrepairable) items via tube.
Make the generic processing machine code willing to complete more than
one processing cycle in one ABM cycle, and more generally to carry
over leftover processing effort after completing a processing cycle.
The src_time meta item now represents accumulated processing effort
(time multiplied by speed) in a scaled form (to retain fractions),
rather than just time in integral seconds. This affects the MV furnace,
with speed 4 and most recipe times being 3 s, and will be essential for
faster furnaces.
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 switching station and supply converter only semantically connect to
cables in particular directions. Make them visually connect only in
the matching directions. This is done by special-casing in the cable
update logic. If more irregular items arise in the future, or the
existing items start to need facedir logic, this should be generalised
into something like the connect_sides system for pneumatic tubes.
If an operating music player was disconnected from the electrical network
or destroyed, it used to leave the music playing forever. There was
also a glitch upon starting playing, as the music was started by the
form handler but then stopped when the run function realised it wasn't
receiving any power, because it hadn't demanded any yet.
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.
To ensure that only rubber tree trunk nodes that are part of trees
regenerate, rather than those that are used as building blocks, check
that they are sufficiently close to rubber tree leaves. This replaces the
older rule that naturally-grown trunks regenerate (regardless of leaves)
and manually-placed trunks don't (even though manually building a tree
otherwise works). The detection of manually-placed trunks was in any
case broken for users of moretrees, because that mod fails to set the
flag signalling manual placement.
Incidentally also fix a bug that caused rubber tree branches (horizontal
trunk nodes) to turn vertical when regenerating latex. Rather than set
the complete node structure, only switch the type name, as does the tree
tap when emptying the node.
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.
Make the injector's mode button lag-resistant. Display the mode on
the button, as is done with other machines' toggle buttons. Describe
the modes using the same words that are now used to distinguish the
corresponding pipeworks objects. Expand name to "self-contained
injector", now that the pipeworks objects are also called "injector".
Show injector item image along with the item name at the head of the form.
Taking the same time per alloying cycle as other alloys meant that carbon
steel was being produced painfully slowly, becuase it processes much less
material per cycle than other alloys. This change halves the cycle time,
which leaves it still processing less material per second than other
alloying processes, but by a less drastic margin.
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.
There was a small amount of dependency of technic_worldgen on the
technic mod, for configuration loading and the top-level "technic" table.
Resolve that by sharing the configuration and top-level table between the
two mods. This means that technic_worldgen can be loaded before technic,
permitting other mods to depend on it without depending on technic.
The centrifuge, currently only existing in an MV variety, is a machine
that separates a mixed substance into its constituents. Currently the
main use is to reverse alloying of metals. The alloy separation recipes
intentionally only operate on the dust form of metals, making this less
convenient than the original alloying. It also only recovers metal
constituents, not the carbon that went into cast iron or carbon steel.
This change incidentally generalises the technic recipe and
machine infrastructure to handle recipes with multiple outputs.
As unified_inventory's craft guide can't yet handle that, these recipes
are not registered there.
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.
For use on servers that have a mainly creative purpose, the setting
enable_corium_griefing=false will prevent corium from flowing far or
unpredictably and from destroying nodes other than water. All reactor
meltdowns will stay contained.
Reactor `explosion' now replaces the reactor core with a corium source
node. Corium is a new liquid, which flows a bit like lava, but has
the additional feature of destroying nodes to which it is adjacent.
It also randomly turns into a solid form, chernobylite, which makes an
attractive building block. It thus gradually melts its way through the
reactor shielding layers; a meltdown gets worse over time if not cleaned
up promptly.
The mechanism for an active reactor core to damage nearby players is
generalised into a "radioactive" node group. Corium and chernobylite
are radioactive, to varying degrees. Players receive a varying amount of
damage from a radioactive node, depending on proximity. Staying outside
a reactor cube is sufficient to be safe from the active core, but not
sufficient to be safe from a melted core.
Make the use of cans more like the digging and placement of ordinary
nodes, and specifically make it much closer to the use of buckets.
The main change is that left-click with a can is now only used to take
liquid; placing liquid is now done with a right-click. This makes the use
of cans a lot less error-prone, compared to the old scheme of determining
the operation based on the type of node pointed to. Other changes are
that liquid placement is now permitted to replace any buildable_to node,
and the cans obey node protection.
Factor out the logic common to water and lava cans. Provide it in the
form of a technic.register_can() function, which can be called by other
mods to register cans for other liquids.
Drop support for negative mesecon control. This requires users of
negative mesecon control to invert their mesecon signal externally.
Comment on rationale for the way toggle buttons in formspec are managed.
The code formerly attempted to make the forcefield emitter controlled
both manually and by (inverted) mesecon signal, but the two interfered
with each other. In particular, a newly-placed emitted would be
informed that it was getting no mesecon signal, and would therefore
enable itself. Fix this by adding explicit modes for how the emitter
will respond to mesecon signals: ignore them, obey them positively,
or obey them negatively.
The manual control could have been incorporated into this mode setting
by having two "ignore mesecon" modes: always-enabled and always-disabled.
But it seems more useful to have a separate manual master switch, so that
the emitter can be manually disabled without losing the mesecon mode.
So it is now implemented that way.
The low capacity of the prospector turned out to be annoying, while the
other limitations do not substantially detract from fun. Also adjust
recipe to include a blue energy crystal, to explain the source of the
charge capacity.
Use silver instead of gold in the recipe for the red energy crystal,
and mithril instead of gold in the recipe for the blue energy crystal.
This provides more appreciable steps in the expense of the upgrades,
which were too similar, and in particular makes the blue energy crystal
less ridiculously cheap.
LV cables are now paper-insulated, rather than uninsulated (which made
no sense). MV cables are rubber-insulated as before. HV cables are now
plastic-insulated (which they already visually appeared to be). MV and
HV cables are still crafted by adding insulation onto lower-tier cable,
rather than by insulating raw copper; this matches the way machines are
upgraded between tiers rather than crafted afresh.
All electric machine recipes now include cable of the appropriate tier
as the bottom-middle ingredient, immediately below the casing ingredient.
Many LV machines were using a copper ingot in that location.
The casing is intended to be an ingredient in craft recipes for machines.
It isn't actually used in any recipes yet. Although mainly a craft
item, it is defined as a node type, mainly to get an appropriately cubic
inventory image. It is incidentally possible to place it as a node:
this makes some sense, although the empty machine casing isn't actually
useful as a node.
The new tool will say whether a target block type is present in a
specified region, to allow for more targeted digging. It is deliberately
quite weak, with several limitations: only stores enough charge for a
small number of shots; target can only be set by pointing at an example
node; range is limited; accuracy is less than 100%. Some of these
limitations should probably be ameliorated, but not entirely eliminated,
in the future when we have a better idea of game balance.
The inventory image is only a placeholder.
Commit ee0765804c broke the fuel-fired alloy
furnace, by removing the definition of its formspec that it requires to
set up the form upon construction.
A typo in commit d55ecc39f9 made recipes
for alloy cooking, compressing, and all other craft types sharing that
machine code, to be shown with three ingredient slots instead of the
correct one or two.
