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.
Before it would remain the same across world reloads, and thus would be
out-of-date after leaving the first world. This architecture technically
allows for running multiple servers at once, though that's not going to
matter that soon.
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.
