ForgeGradle (probably sensibly) yells at me about doing this. However:
- There's a reasonable number of mods doing this, which establishes
some optimistic precedent.
- The licence update in Aug 2020 now allows you to use them for
"development purposes". I guess source code counts??
- I'm fairly sure this is also compatible with the CCPL - there's an
exception for Minecraft code.
The main motivation for this is to make the Fabric port a little
easier. Hopefully folks (maybe me in the future, we'll see) will no
longer have to deal with mapping hell when merging - only mod loader
hell.
Maybe the capability system was a mistake in retrospect, as we don't
store the peripheral outside, so there's no way to reuse it. That will
probably come in a later change.
As a smaller fix, we pass the invalidate listener directly. The lifetime
of this is the same as the computer, so we don't create a new one each
time.
There's still the potential to leak memory if people break/replace a
computer (as listeners aren't removed), but that's an unavoidable flaw
with capabilities.
Fixes#593
This exposes a basic peripheral for any tile entity which does not have methods
already registered. We currently provide the following methods:
- Inventories: size, list, getItemMeta, pushItems, pullItems.
- Energy storage: getEnergy, getEnergyCapacity
- Fluid tanks: tanks(), pushFluid, pullFluid.
These methods are currently experimental - it must be enabled through
`experimental.generic_peripherals`. While this is an initial step towards
implementing #452, but is by no means complete.
This registers IPeripheral as a capability. As a result, all (Minecraft
facing) functionality operates using LazyOptional<_>s instead.
Peripheral providers should now return a LazyOptional<IPeripheral> too.
Hopefully this will allow custom peripherals to mark themselves as
invalid (say, because a dependency has changed).
While peripheral providers are somewhat redundant, they still have their
usages. If a peripheral is applied to a large number of blocks (for
instance, all inventories) then using capabilities does incur some
memory overhead.
We also make the following changes based on the above:
- Remove the default implementation for IWiredElement, migrating the
definition to a common "Capabilities" class.
- Remove IPeripheralTile - we'll exclusively use capabilities now.
Absurdly this is the most complex change, as all TEs needed to be
migrated too.
I'm not 100% sure of the correctness of this changes so far - I've
tested it pretty well, but blocks with more complex peripheral logic
(wired/wireless modems and turtles) are still a little messy.
- Remove the "command block" peripheral provider, attaching a
capability instead.
So very little works, but it compiles and runs.
Things to resolve over the next few days:
- Horrible mappings (should largely be resolved by tomorrow).
- Cannot send extra data over containers - we'll have to see what Forge
does here.
- Turtle models are broken
- No block drops yet - this will largely be cherry-picking whatever I
did on Fabric.
- Weird inventory desyncs (items don't show up initially when
interacting with a CC inventory).
- Probably lots of other things.
Look, I originally had this split into several commits, but lots of
other cleanups got mixed in. I then backported some of the cleanups to
1.12, did other tidy ups there, and eventually the web of merges was
unreadable.
Yes, this is a horrible mess, but it's still nicer than it was. Anyway,
changes:
- Flatten everything. For instance, there are now three instances of
BlockComputer, two BlockTurtle, ItemPocketComputer. There's also no
more BlockPeripheral (thank heavens) - there's separate block classes
for each peripheral type.
- Remove pretty much all legacy code. As we're breaking world
compatibility anyway, we can remove all the code to load worlds from
1.4 days.
- The command system is largely rewriten to take advantage of 1.13's
new system. It's very fancy!
- WidgetTerminal now uses Minecraft's "GUI listener" system.
- BREAKING CHANGE: All the codes in keys.lua are different, due to the
move to LWJGL 3. Hopefully this won't have too much of an impact.
I don't want to map to the old key codes on the Java side, as there
always ends up being small but slight inconsistencies. IMO it's
better to make a clean break - people should be using keys rather
than hard coding the constants anyway.
- commands.list now allows fetching sub-commands. The ROM has already
been updated to allow fancy usage such as commands.time.set("noon").
- Turtles, modems and cables can be waterlogged.
OK, so let's get this out of the way, there's some actual changes mixed
in here too. I'm really sorry:
- Turtles can now not be renamed with unnamed item tags (previously it
would clear the name, this seemed a little unideal).
- commands.getBlock(s)Data will also include NBT.
Now, onto the horror story which is these inspection changes:
- Make a lot of methods static
- Typo fixes
- Make utility classes final + private constructor
- Lots of reformatting (ifs -> ternary, invert control flow, etc...)
- ???
- Profit!
I'm so going to regret this - can pretty much guarantee this is going to
break something.
There's several reasons for this change:
- Try to make ComputerCraft.java less monolithic by moving
functionality into separate module-specific classes.
- Hopefully make the core class less Minecraft dependent, meaning
emulators are a little less dependent on anything outside of /core.
Note we still need /some/ methods in the main ComputerCraft class in
order to maintain backwards compatibility with Plethora and
Computronics.
